The Morserino-M32 Reborn

Back in 2024, I wrote about the Morserino CW keyer and trainer, bemoaning that although it looked ideal for my needs it was no longer available due to vital components being discontinued. Note the spelling – don’t put in an ‘h’, as it may take you to a dodgy website.

Whilst researching the QRP Labs Transceiver kit, I noticed (somewhat tucked away, it has to be said) that QRP Labs had the Morserino M32 Pocket for sale for $80.  Yes, they have acquired the licence to manufacture an updated version of this device in a ‘pocket portable’ version.  Since I was buying the QMX+ transceiver kit and paying for delivery, it was a no-brainer to add the Morserino to my order.

I haven’t yet had much time to investigate all its features, but I have tried the capacitative keyer in iambic mode B (the default) and it is delightful. It shows its interpretation of what you are keying and it can also play random morse characters, words, call signs, etc, etc, for practice copying.  I’ve been neglecting my keying and I can see that I’m going to make a lot of use of it.

Because the keys are capacitative, they’re not vulnerable to rough handling, whilst the feel is not much different from the mechanical paddles of my keyer, which are set to a very light touch as recommended by the experts at my club. However, the device is very light and doesn’t have any feet, so will slip around the table unless held down.

It can run from an internal rechargeable cell, so it really is a pocket device. For scale, it is about 12 cm long, 5cm wide and 2.3 cm high
( ~ 4¾ x 2 x 1 inches). (The red labels are mine!)

You have to buy the internal cell yourself, as they can’t send them by courier: it’s an AA size 14500 Li-ion 3.7 v cell with a ‘button’ end, which I had to get from Ebay.  Be careful, as there are a variety of similar cells which have different voltages. You have to unscrew the four screws on the base and lift out the circuit board to fit the cell. When replacing it, ensure that the three wires to the paddle don’t obstruct the speaker or the input knob.

My battery was partially-charged and took some hours to recharge.  Plug a USB C cable to an ordinary cell phone charge and remember to switch the battery switch ON, otherwise it doesn’t recharge.

My M32 Pocket came with firmware version 7 installed but they are now on version 8 which has the Morse learning games and various other improvements. I was able to update the firmware easily from my PC where I have the Google Chrome browser installed. Go to the https://www.morserino.info website and then use a proper data cable to connect the USB port of the M32 Pocket to a USB port of the computer.

Follow the on-screen instructions on the web page to install the required update. You have to say which computer port to connect to.  In my case it was COM3 (Java). It took a few moments to download and install, then the device restarted, giving access to the new features.

I am writing a separate blog about my initial experience with using it.

IZ2UUF Morse Koch CW App

It’s April Fool’s Day, so a good time to review my progress with learning Morse.

I’ve been attending the Sutton and Cheam Radio Society’s regular Monday evening meetings, where a group of us are trying to improve our CW.  Their shack is on top of Epsom Downs, in an excellent location with long uninterrupted views north and south. They’ve got a decent long wire dipole HF antenna and a couple of vertical VHF antennas.  We have been able to hold QSOs with a large number of European stations.

IZ2UUF Morse Koch CW  Android app

I realise that I need 20 wpm to be able to hold QSOs and I’m not getting there using LCWO, so I’ve just started to use IZ2UUF Morse Koch CW, which is an Android app.

I’m finding it excellent. You can select the number of characters (which build up in the same order as LCWO or its own order), the speed and the length of the test.  It sends them on the phone  both in Morse and letters on the screen.  The nice thing is that it repeats each group three times, which is brilliant when you need to catch something subtle.  After each group, it then speaks the characters, so you don’t need to look at the phone, which is good if you’re using headphones whilst walking, for example.

I think I’m making progress.  I’m running it at 20 wpm since I do know at least 40 characters.  My main problem at that speed is confusion between a character and its inverse, such as F and L or K and R.

Obviously at that speed you can’t think about each character, they just have to trigger the correct response.  This is where the repetition is very helpful.

At present I’m using the free version, which has all the features I need right now. I’m thinking of upgrading to the PRO version so that I can do the simulated QSO exercises.

The author of this App is to be highly commended for what must be the best Morse app out there.

Morsle Morse Game

I have just learnt about a Morse Challenge Game at https://morsle.fun/

Each day you are given a five-letter word presented initially at 40 wpm, which initially just sounded like a lot of buzzing to me.

You have to enter your guess at the letters and then any that you get right turn green.  You then get two more goes at that speed.  If you haven’t got it, the speed reduces by 5 wpm to 35 wpm and you have three more goes, and so on.  You can save your statistics and the next day there is another word.  There is also a practice mode if you are trying to improve or you don’t want to wait !

I did manage to get a word at 40 wpm!  This was partly a lucky guess, but funnily enough, the ‘shape’ of the letters did stand out.  For example, you can hear how many symbols are in each letter and perhaps which ones are long and which are short.  The real thing is that with only five letters, you can retain the overall ‘buzz’ and there is then time to think about it.  Very different from a continuous stream of traffic where you have to recognise each letter immediately.

Good fun – worth giving it a go.

Learning Morse

It’s the end of August 2025, the anniversary of me starting to learn Morse seriously. It’s time to review progress and note any lessons that I’ve learnt.

What stage have I reached?

I can read words at a speed of 15 wpm, but with delays between words, so I can’t really manage sentences at that speed. This is because I hesitate over characters, and then miss the next word.
My effective speed is more like 12 wpm.

Overall, I have put in about 2,000 lessons using the LCWO (Learn CW online) app.  This amounts to at least  200 hours of practice, or about 4 hours a week.  It feels like a lot more.

I can send with a Morse paddle and keyer, again at an effective speed of about 12 wpm, but my accuracy and rhythm leave much to be desired.  To send rhythmically, you need to be thinking ahead whilst sending, and this requires you to employ some of the brain’s ability to process characters subconsciously.  This is the same ability that you have to use in order to read Morse at anything more than a snail’s pace.

So at my stage, where I do know about 45 Morse characters, sending helps to improve my reading and vice versa.

Lessons learnt

I have been re-reading some of Chris Rutlowski‘s book on learning and using CW, which I bought a year ago.  The learning process he described made little sense to me at the time – he spends quite a lot of time describing the rhythmic nature of keying, but it isn’t possible to attain a rhythm until you can recall the characters effortlessly.

However, I now appreciate that sending accurately, even using a paddle and keyer, requires you to become much more aware of the rhythmic nature of the character train.  Unless you are aware of this, you will leave incorrect gaps between letters and words that cause confusion to the listener, especially when they’re using a decoding app.

I feel that I should have started to practice keying a little bit sooner, because both sending and reading Morse at a decent speed does require you to feel the rhythm of the characters. However, I didn’t make any progress until someone suggested the https://hamradio.solutions/vband/ website.  This lets you practice keying on a practice channel, or to open a channel with your known contacts.

I have managed a couple of QSOs over radio with friends, but I feel that I have a long way to go to be able to manage 15 wpm reliably, as this seems to be the speed that is needed for straightforward QSOs.

I intend to ‘plug on’ until I reach this stage.

First QSO attempt

I’ve been practising reading Morse using various software tools for around 11months and I’ve been practising keying for a couple of months, using a twin-paddle key.  I can read 10 wpm on a good day, and as others have found, it is slightly easier to key at the same speed, although my ‘fist’ isn’t good.

As I’ve said before, the whole purpose of radio is to communicate and I was very pleased when a friend at the local radio club suggested that we try a QSO (two-way radio contact).

Antenna and Rig

I’ve not yet tried to transmit even though I’ve had a Windom (asymmetrical dipole) antenna since October. My friend is about 10 miles from here, at a low-lying location close to the Thames.  My aerial can supposedly operate from 10 to 80 metres (28 MHz down to 3.5 MHz) although my radio can go down to 1.8 MHz.

Bands

We tried 7.010 MHz to start with, as the band was fairly quiet.  We soon found out why – propagation conditions must have been poor – I could just hear a transmission but there was too much noise for communication.

We then tried 14.005 MHz but that was very noisy.  3.505 MHz and 1.997 MHz were just as poor.  Then we tried 28.005 (i.e. the 10m band) and I received him 599 (i.e. loud and clear). But he couldn’t hear me even though I’d cranked up to 100 watts. That doesn’t make sense, as reciprocity should apply to the signal path: if his signal can reach me, my signal should reach him.

I couldn’t find anything wrong and we’d run out of time.

Trouble-shooting – the BK-IN setting

Coming back later, I realised I had probably fallen into a trap on my Yaesu FT-710.  I set its CW keyer to Elekey (Iambic) Mode B at 10 WPM and I’d set the BK-IN (break in) mode to ON.  This means that the keyer transmits as you key.  If BK-IN is off, it only produces a side-tone that lets you hear what you’re keying, but it doesn’t transmit.

Set for each band
BUT, what I hadn’t realised is that the BK-IN setting (which is set from the touch-screen menu) has to be turned ON for each band separately.  If you change bands then BK-IN won’t be on unless you have previously set it. You have to open the touch-screen menu, find the BK-IN  box and change it.  I suppose this is fail-safe, but there isn’t much indication of the setting, except that the transmission indicators on the tuning dial turn red when the transmitter is sending.

However, I’m inexperienced and I’m thinking about what I’m keying, rather than looking at the radio, so I didn’t notice this.

Accessibility of controls

Unfortunately, the touch-screen menu isn’t that easy to access and use unless you’re very familiar with the radio.  This is the downside of a radio that basically only has two knobs to adjust the settings. For example to change bands, you press the band button on top of the radio but this just brings up a screen with all the bands that can be accessed – and there are a lot.  You then touch the screen to choose the band you want.  So a lot of the settings are fiddly to reach.  Of course, by omitting lot of hardware knobs and switches, the radio can be smaller, cheaper and more reliable  but it becomes more fiddly to operate.

We have arranged another session, so I’m keeping my fingers crossed.

Sending Morse

How to practice sending morse

It is July 2025 and I’ve been learning to read Morse for 11 months. On the lcwo website, I can manage 10 wpm in plain language on a good day, but I’ve been stuck on how to learn to send.

At one time, you could practice ‘off air’ with another ham at your local radio club, but this has limitations – not least as to when you can practice.

Websites

I’ve now come across https://hamradio.solutions/vband/

This is a website that lets you practice privately using your web-browser or you can create or join a ‘channel’ to communicate with another user or users, without a radio connection.  So you can set up with a friend to practice wherever and whenever convenient.

Dongle

You need a ‘dongle’ to connect your key (using a conventional jack plug) to the USB port of the computer and you can immediately connect to the practice channel, which is private.  All the usual single and dual-paddle modes are supported, with the default being iambic-B.  In this mode, the keyer remembers any key that was pressed during the playing of the previous key.  This means that if you squeeze both keys together, you can get R, K, A, N, C or . (stop) depending on exactly which key you touch first and when you release each key.

Dual-paddle key

I have one of the cheapest dual-paddle keys I could find, with a heavy steel base so it doesn’t slide around the desk, see the photo at the top of this page. You can adjust the contact distance of each paddle and also the total pressure required.  I have set the contact distance to the smallest value that doesn’t cause inadvertent contact and a fairly high contact pressure so that you can feel the contact.

I’ve not tried any other dual-paddle keys although you can easily twice to four times as much, i.e. over £200.  The expensive keys certainly look pretty but I’d need a lot more than that to justify buying one.

How is it going?

I’m right at the earliest stage, discovering the best way to use squeeze keying. This is taking a lot of practice to understand as the timing is very critical.  I’ve got it set to 12 wpm, which is a good compromise between the character speed of 18 wpm I set for reading (but spaced to the effective speed of 9 or 10 wpm) and the speed at which I can operate the key.

The main issue I’m finding at the moment is avoiding extra dits: because it remembers the dit key being pressed whilst a dah is being emitted, it is easy to get an extra dit tagged onto characters, or even a double dit before a dah.  This means that I can’t key reliably at any speed at present.

I will report again after a bit more practice.

The Amateur Licence Conditions in 1971

It is interesting to read the Licence conditions that applied in 1971 when I took my Radio Amateur Exam.  I’m specially interest in the Morse test, which was as follows.  In essence, you had to send 36 words at 12 words per minute, and 10 five-digit groups at about 6 words per minute.

The receiving test was the same. Four corrections were allowed in the word element, and two in the digit element, both sending and receiving.

Punctuation symbols were excluded.

The Morse Test Official Requirements

In the sending tests a candidate is required to send 36 words
(averaging five letters per word) in plain language in three minutes
without uncorrected error, not more than four corrections being permitted,
and

10 five- figure groups in 1½ minutes without uncorrected error, not more than two corrections being permitted.

In the receiving tests, a candidate is required to receive 36 words
(averaging five letters per word) in plain language in three minutes, and
10 five- figure groups in 1½ minutes. Each letter or figure incorrectly
received counts as one error, A word in which more than one letter is incorrectly received counts as two errors. More than four errors in plain language and more than two errors in the figure test will result in failure .
The tests will not include punctuation or other symbols. The foregoing particulars are summarised in the following table:-

Learning Morse Code

In earlier decades, the ability to ‘read’ Morse code was necessary to get a full ham licence .  I had no easy way to learn it – I annoyed my family trying to persuade them to help and I gave up.

It is worlds different with the Internet, and I have subscribed to LCWO.net (Learn CW online).  CW means ‘continuous wave’ and is used to refer to Morse, since this is sent by switching a continuous RF carrier on an off, using a Morse key. (The tone you hear in the receiver has not been transmitted – it is generated by the receiver when the carrier is detected.)

LCWO uses the ‘Koch’ method of teaching Morse, and I really like it very much indeed.

It presents Morse characters in a structured way over 40 lessons, starting with the letters K and M (·– and ).  Each lesson introduces a new letter, starting with the 3-character letters, i.e. U and R (··–, ·–·), then adding further letters E and S (·, ···), continuing to build up letters with small differences.

You are presented with groups of 5 characters at random from the set you are learning, in a 1-minute sequence.  You are encouraged to keep the character speed at 20 WPM so that you learn the sound of each letter.  You are not supposed to learn the sequence of dots and dashes.  As you receive a group, you can write the letters on paper or type directly into a window on-screen, and then ask the system to check for errors.  I couldn’t write them down quickly enough by hand, but as I’m a touch typist, it was possible for me to type them into the checking window.

At first it was very difficult to recall and type the letters, but you can increase the letter spacing and I found that I could manage with a character speed of 20 WPM but letter spacing of 10 WPM.  Each time you run it, the character sequence is different and I have a feeling that it more frequently presents the letters you get wrong.

For example, I could not distinguish R and K, whilst I had no problem with S and U. R caused my brain to freeze and by the time I’d decided it was an R, and not a K, I’d missed the next group of letters.   E and M are easy, but the shorter letters take less time so need a quicker response when typing.

Progress

I’m going to blog my progress as an experiment which might help future traveller on the same journey.

First Report – 11th September 2024 – on Lesson 6

My first lesson was on 3rd August 2024.  However, I had 2½ weeks away  in August , so I’m charting my progress from 11th September 2024.  At this point, I have spent maybe 30 minutes a day for 6 weeks on it, and I’m on lesson 6, so I’m not a great student.  But some of the letters are now starting to ‘sing’ to me: I don’t have to think, but I’m still hoping to see the letters appearing like writing in my mind’s eye! I’m hoping to have completed the lessons by Christmas and to start increasing my speed.  We’ll see!

12 days later – lesson 9

Now I’m on lesson 9, so that’s 4 days per lesson. With 31 lessons to go, that’s 124 days or 4 months, I’m looking at the end of January 2025 at this rate!  My problem is confusing A and N, R and K. I’ve been practising just these four letters in the hope that I won’t keep hesitating over them, but I find R is a real menace.

Reading the experience of others, it seems that 10 words per minute isn’t a bad speed, and that when you’re writing the letters down, it is quite difficult to get above 15 words per minute, which is 75 characters per minute, so well above 1 character per second.  To go faster, you need to be a touch typist.  If I ever get to 20 wpm, I’ll be super delighted.

Day 21 – 2nd October

I’m on Lesson 10 – Letter L –  thus my progress has slowed.  I have been practising regularly but perhaps not intensively.  My issue seems to be hesitation over letters beginning with ·– of which there are many: A, R, L and P, along with confusion of ·– and –·  So I have decided to stick with this lesson until these become embedded.

Day 30 – 11th October

I’m still on lesson 10, but to be fair I did have 6 days away, so I have had 8 practice days on this lesson.  After my 6 days away, I’d certainly dropped back and had to spend two days practising my ‘bogey’ letters, which helped a lot. I’m starting to enjoy the differences between A, R and L (increasing number of dits after the dit-dah).

I’ve decided to move on to Lesson 11 which is W (·–).  My brain is saying, ‘Oh, that’s unfamiliar!’ so I must be starting to recognise some (but by no means all) of the other characters without conscious thought.

Day 42 – 23rd October – Lesson 12- letter I (··)

I’ve had a long weekend away and it really does make a difference. Although I know all the letters, I sometimes have to think,  which means that I miss the next ones in the sequence. This is the half-way point in the alphabet and I’m going to try to consolidate these before moving on.

Day 51 – 1st November – Lesson 13 – Stop (·–·–·–)

I’ve now submitted 300 attempts and my average score is over 90 %, but I don’t submit attempts that are clear failures – such as when I get completely lost. In actual fact, I reckon I’ve done at least twice that many listenings that I have discarded.  I’m moving on to lesson 14 (letter J) today. I feel that I am getting better at rapid recall, and occasionally I know a letter without consciously thinking ‘what was that?’.  It’s quite a strange feeling when the letter just appears.

Day 60 – 10th November – Lessons 14 J (·–) and 15 Z (··)

Really struggling! I’m running at a letter speed of 20 wpm with an effective word speed of 9 wpm but I’ve put in an additional word spacing of 0.1.  The extra word spacing has helped to improve my accuracy greatly, because it gives me a little more recall time when necessary.  Still an average of 4 days per lesson, with 26 to go!

Day 68 – 18th November – Lesson 16 =(···–)

Now over 360 attempts and I’m plugging on with the next character, the = sign, sounding very different from anything else. Not half-way yet.  I’m really trying to listen behind each sound – my main problem has become slow recall of some obstinate sounds.

Day 78 – 28th November – Lessons 17 (F··–·), 18 (O), 19 Y(–.)

Over the last 10 days I’ve added around 80 attempts and 3 new letters. It isn’t getting easier because more letters are being thrown at me and so there is more opportunity for confusion: for example F and U are quite similar.  However, I no longer need to think about some of the early letters, so they must me gradually sinking in.

Day 92 – 12th December – Lesson 20  ,(··––)

I’m back after a week away from home.  I spent several sessions practising the eight characters giving me most trouble to ensure I could distinguish them at 20 wpm, but I’m still not perfect on them.  Since first starting, I have now registered 566 attempts, but as I’ve said previously, this excludes attempts that I failed to complete.

Day 100 – 20th December – Still on Lesson 20 , (··––)

It’s Day 100 and although the only real significance of this is an artefact of our choice of numerical base, it’s still worth a note.  I haven’t made progress. I think this is partly because I have been busy with other tasks so have only registered 30 attempts since day 92.  Problems occur when I have to think about a character causing me to  miss the following ones. I have come to the conclusion that sessions lasting less than half-an-hour don’t help me to get better at all. I probably could manage the next letter, V, as it seems simple and distinct. but I’m reluctant to move on until I’ve really firmed up this first half.

Day 109 – 29 December – Lessons 21/ 22  Letters V (···–) and G (·)

This is essentially my end of year report. I’ve just now moved to letter G, which is still very unfamiliar, after finding V fairly easy.   I’ve now submitted 625 attempts, and I have now slowed down to 5 days per character, although that includes several days off during December.   I’m still finding = difficult, even though I started it 40 days ago.  However, I can at last hear the three dots in the middle of that character, so hopefully it will now be easier, as lesson 23 is the digit 5, which is five (rapid) dots.

At this rate of progress, I’m looking at completing the lessons by the end of March – that means I will have taken twice as long as I thought when I started in early August. However, my effective speed should be around 8 wpm, which would be fairly reasonable.

Day 118 – 7 January 2025 – Lesson 23  Digit 5 (·····)

I moved onto lesson 23 – Digit 5 – on 30 December, 9 days ago, because I’d found V, in particular, easy.  But I then had a couple of days off at New Year, mainly because I had a bad cold.  This has set me back.  My problem is hesitation – not instantly recognising certain characters – rather than confusing some characters, so I guess it is recall speed that I’ve got to improve. I’ll plug on, but it seems a long road ahead.

I’ve made some enquiries about sending practice.  My big problem is that most of my evenings are taken up with bell-ringing practice. These practice nights have been settled for decades and are immutable.  I take Monday evenings off to attend my local radio society, but they’re not doing much practical work at present.

Day 128 – 17 Jan 2025 – Lessons 24 & 25:  / (–··–·) and Q (––·–)

I’ve spent most of the past ten days practising ‘code groups’ with the last ten characters as I was finding these more complex patterns difficult to recall quickly.  This means my learning rate has dropped to 5 days per character.  Next we start plugging away with the other digits. At the present rate, that’s another 75 days – still on track for the end of March.

Day 142 – 31 Jan 2025 – Lessons 26 & 27:  9(––––·) and 2 (··–––)

We’re really getting into the long characters with these digits. I’ve had several days away on other things, so progress is slow. My accuracy is not improving and with more digits and some long letters to follow, I must get my head down again.

Day 148 – 6th February 2025 – Lessons 28 to 30: H, 3 & 8

Lesson 30 – only 10 more to go! But my rate has dropped to 5 days per lesson and I’m trying to avoid the temptation to rush through the last 10 characters, because I can still finish by the end of March.  I’ve had a total of 778 attempts including both the lessons and the character groups.  That’s five attempts per day on average. I’ve used the character groups to help firm up the distinctions between some characters that I hesitate over.  Looking back, it’s interesting to note that some characters that gave me trouble are now as clear as a bell, although some that were clear have become muddy.  For example, S was quite clear, but now I’m onto H, distinguishing S, H and 5 (···,····,·····) needs more effort.

Day 157 – 15th February 2025 – Lesson 31: B (–···)

I’ve had a total of 814 attempts so far and I’m really struggling with the digits – I’ve done 5, 9, 2, 3 and 8, so that’s half of them. I know the distinctions between them but I often have to think about what I’ve just heard. Interestingly, I’ve become reasonably good at distinguishing S, H and 5.  My problem is still speed of recall since moving back from the code groups to all 31 characters. With three letters, 5 digits and one symbol left, the end is in sight. I’m glad because I’m getting a bit disheartened regarding my speed of recall.  All I can do is to practice every day: I do think I’m putting the time in.

To keep up my rate of progress, hopefully I will have tackled ? and 4 by the next report. I’ve had a few long sessions today and I think I’m making progress again.

I note that the old Post Office Morse test didn’t include any symbols, and that letters and digits were tested separately.  However, since call signs are a mixture of letters and digits, that was a bit of a let-off.

Day 168 – 26th February 2025 – Lesson 32: ? (··––··)

I’m up to a total of 700 attempts on lessons  and 151 on code groups. I haven’t been doing as many attempts per day due to other demands, but my accuracy is improving and I’m ready to start Lesson 33 (digit 4) today. It will be a tall order to finish the lessons by the end of March.

Day 177 – 7th March 2025 – Lesson 33 – 35: 4 (····–),  7(––···), C (·–·)

Perhaps I’ve stepped on a bit too far in 9 days but 7 and C are familiar to hams anyway.  There are 2 letters (D and X) and three digits (0, 1 and 6) to go and 24 days to the end of the month, so I could finish all the lessons by then, although I will be away for a few days. I’ll need to intensify my practice, as speed of recall is once again an issue, especially some of the punctuation characters.

Day 189 – 19th March 2025 – Lesson 36-37: 1 (·––––),  D (–··)

I’ve been away for a long weekend, which has limited my progress, plus getting a new Anytone Hand-held (mentioned elsewhere) has been a distraction. My speed of recall has worsened with being away, but with three more characters left, I can hopefully cover them in the 12 days remaining this month.

Day 196 – 26th March 2025 – Lessons 38-40: 6(–····), 0(–––––) ,
X(–··–)

Yippee! I’ve reached the last of the 40 lessons and now need to improve my speed and accuracy.  I can manage all characters sent at 20 wpm  with a character spacing giving 8 wpm plus an extra 0.1 word spacing. The characters I learnt earlier on, especially those with special uses, now ‘speak’ to me – in other words, I just know them.  I’ve spent the last few sessions using the custom code groups feature to rehearse similar characters, especially B, H, X, =, ? and the digits, as I’m still hesitating or getting them confused.

End of March 2025 My Goal is Reached !!

So I have reached my goal of learning the first 40 characters.  I shall now gradually increase the effective word rate – I’d like to reach the old Post Office test rate of 12 wpm, and then start sending practice.

I’m told that one reaches barriers at certain points and that these can require a lot of persistence to breach.  This has been my experience with change-ringing, which has taken years of persistence. I just hope that my brain hasn’t become too inflexible.
