I’m sorry for the late reply, John.

Glad to hear the IDE is working for you and you were able to update the units.

If you are up for it, I recommend trying the firmware updater at a reduced serial port rate, say 115200, and let us know what you find.

Thanks for the prompt reply. I wanted to provide an update.

-Most importantly, I was able to get 4.1 installed on both my machines.

-I was not able to use the Morserino-32 Firmware Updater to do so. After deleting all the firmware images and re-downloading (to verify files were not corrupt), I attempted the steps in appendix 4 again. I got confirmation via the CMD prompt that the update was successful but still nothing was displaying on the LCD. I then attempted the appendix 4 with the addition of the "erase" command. Still nothing.

-I found the solution to be the IDE software. After figuring out how to use the software, I was able to compile V4, and upload. Both machines now seem to be in working order at this time.

I appreciate your help and if there is a solution to get the Morserino-32 Firmware Updater to work I am all ears.

I am a Flex radio user. I use the remote keyer software to have the keyer or Morserino key my radio remotely. The software provides side tone. It is free snd runs on Windows. I use a RS232 interface for a straight key. Although there is a slight delay. You do not need to connect to a Flex with this software. You just select the correct com port and place an empty phone jack in the Morserino. Works great with my cell ops class.

It worked only partially, but I attribute my shortcomings to not fully utilizing the LineOut from the Morserino as Willi suggested above.

My next step will be to develop a hardware mixing device, basically a set of Op-Amps wired as summing amplifiers.

The trouble is not trivial:
We need to mix the PC microphone electret style with the sidetone output of the morserino.
We also need to mix the sidetone output from the Morserino into the Headphones of your PC headset... so the audio coupling occurs from the headphones to your ears.

The way I see it: we basically need to Wye (split) the sidetone output from Morserino, and then using summing amplifiers mix the sidetone with two signals: the PC headphone and also the PC Microphone.

If you try to use the PC LineIN to carry the sidetone, you'd need a software solution to send the sidetone to the Zoom call.

My lack of understanding of impedance is my downfall.  I don't think you can simply sum together the lineout from Morserino with the Mic input of the PC Headset.

Thank you very much for the responses above.  I used the M32 TRRS output and got clean audio using the line-in on the PC.  Here is a breakout cable that worked well https://www.amazon.com/Qaoquda-Balanced-Terminal-Adapter-Connector/dp/B07RXS3ZYN/ref=mp_s_a_1_4?dchild=1&keywords=Trrs+breakout&qid=1617335181
During my CWOps class, I switched Zoom audio from "Mic" to "Line in" and the group felt it was not appreciably better than what I sounded like with acoustic coupling over the microphone. So I haven't pursued mixing yet.  I'll try the VAC software which looks interesting.

It could be a cold solder joint that intermittently goes open.

I might suggest re-flowing the solder joints.

Hi Willi,

I tried two different phone chargers, a dedicated Raspberry Pi power supply and the USB port on two different computers. All with the same results. Also I used at least three different cabels which all do power my Rpi very fine!

Power via USB stopped working after just one hour #issues #morserino

Florian Meißner DO1MRV
 

Hi @all,

After I received my Morserino 2nd generation, Firmware 4.0.1, last week, I finally assembled it today and tested it. Therefore I powered the Morserino via its USB port on the Heltec module and it stared up fine as expected. But after about an hour, the Morserino stopped working completely that way. No more LED indications, dark screen, no sound what so ever.

But when I disconnect the USB cable and instead power the Morserino via the Lipo battery, it still works like a charm. So as already discussed in https://morserino.groups.io/g/main/topic/78721108?p=,,,20,0,0,0::Created,,usb,20,2,20,78721108,ct=1&ct=1, there seems to be a problem with the 5V distribution from the USB socket.

I also did measure the voltage across the power pins of the Heltec module in the following configurations. For all tests with USB power I used the same powerbank / cable setup, the powered the Morserino successfully at the beginning as well as several different USB power supplies and PCs.
Heltec module inserted in the Morserino
Powered via USB, battery disconnected
5V - GND       0V
Vext - GND    3,3V
3V3 - GND     3,3V
Powered via battery, USB disconnected
5V - GND       0V
Vext - GND    0V
3V3 - GND     0V
Heltec module removed from Morserino
Powered via USB, JST on the bottom disconnected
5V - GND       0V
Vext - GND    0V
3V3 - GND     0V
Unfortunately, the thread linked to above did not mention what really was at fault. I hope, you can help me with this one. Since the Morserino is brand new, it is somewhat disappointing that one function quit that rapidly!

73,
Florian DO1MRV

Well ... it seems 70 year old eyes are not quite as sharp as they once were.  Touched up all of the rotary solder joints and now everything seems to work as designed.  You have done some great work.  Thank you!

Gday,

I'm looking for VK Morserino Ops interested in using Zoom for practice and a chat. I'm new to both Zoom and Morserino.

In 1988 I passed 5WPM for my Novice Call, but life got complicated and CW was dropped and I never got to sit for the 10WPM exam. My K Call, VK8KMD was grandfathered into an Advanced Call. I still feel guilty about that, and feel I should be able to have an on-air CW QSO at 10WPM or more.

I love the Morserino for its wide range of learning options. I'm 73. It would be nice to meet Ops who are awake when I am.  Alice Springs time is UTC/Zulu +9.5 and doesn't move from that.

I'm on QRZ.com.  73 Greg VK8KMD
