Thanks for the comments...I have 3 boxes, one of them is flakey in that it locks up...I redid the firmware, still flakey...I think I have an extra chip...will try and replace???

SO2R Box sending at <1 WPM
My trusty old (10+ years?) SO2R box just started sending CW at <1 wpm.? No matter what I did with N1MM's or the box's internal speed control, no change in CW speed.? There are 3 different DIP ICs of which there are two of two types.? I swapped both "pairs" and reseated the single DIP.? I then reloaded the firmware and, voila, it's back to working perfectly again!
?
I guess corrosion had built up on the pins over the years (it is humid in SE Texas) or a nearby lightning surge had scrambled something.? Anyway, the bottom line is that if you see this behavior in your trusty SO2R Box, it may not be catastrophic.? These things are built like tanks in my experience.
?
Good luck,
Bob K5WA

This group is for the YCCC SO2R Box.? The SO2R Mini group is SO2RMini.
The SO2R Mini does not speak the OTRSP protocol.? On Windows there is a program which communicates via OTRSP and talks to the Mini using the commands which are an extension to the WinKey protocol.
??? Paul, K1XM
I'm making the move (back) to a linux desktop after many years away. I've got solutions for many of my issues but finding a way to control my SO2R mini is one of the remaining tasks.?
?
I've looked at the OTRSP command set and it seems simple enough, but I'm not having any luck getting the commands to the box. If I need to send something like "RX1" to the device, is that expected to be ASCII or Hex encoded??
?
I've attempted to just echo some commands to the serial device with no luck. Bringing up a terminal program attached to the port at n81 9600 baud doesn't do anything either.? I know I have the correct port from the output of dmesg and watching the connect/disconnect messages.?
?
Any input would be appreciated!?

My ultimate goal was to get it working with my elgato streamdeck, which should be simple enough if I can figure out this issue.?

The voltage loss is due to a bad via on the board.? You jumpers it the same way that I’ve done it.
The old part number for that IC is a 2502-4.? The revised part number is a TLP542 or similar.? I’ve used several different ICs of that same numbering range.? I can look tomorrow- I may have one in the garage I can send you.

Update on Low audio:
?
From my good friend WD8DSB:
Today Mike (W9RE) and I did some troubleshooting on a YCCC SO2R box at Mike’s and found we had lost 5 Vdc on pins 11 and 15 on the MAX9722A but we had 5Vdc on pins 2 and 3. We then did continuity checks and saw something like 3 Meg Ohms between pin 2 and 15 as an example. We decided we must have had a broken trace so we installed a jumper between C104 and C107 pins that normally have 5Vdc to reestablish 5 Vdc on pins 11 and 15 and this fixed the original problem of no audio output.
?
BTW my box has a white DIP for U3 where my spare (just repaired box) has a black DIP for U3.? I am not using Icom rigs right now but should I replace it anyway?? If so what part number should I order?
?
Thanks,
?
Mike W9RE
?
?
I obtained? a spare (backup) SO2R Box+ and comparing it to my original unit I notice that the audio is say a good 6db lower when listening to radio 1 when plugged into either channel 1 or channel 2.? This is only with the radio plugged into either DIN,? 12Vdc and audio out plugged in and of course flipping the rx switch.
?
Any things I should check or buy for replacing??
?
Paul was there a chip that was universally replaced in the original buy?? I think the vintage of both units is the same.? Seems like I remember something about a green or white device that should be replaced (updated)?
?
Tnx,
?

Hi Mike,

There were some units that had bad solder connections on one of the surface mount chips - I think it was the audio amplifier.? I would open it up to check.

Before you open the SO2R Box remove the speed pot knob and the nut that holds it to the case.? If you don't you will damage the pot.

Once you have it open, connect it up and try it.? While you are listening to the audio press on the leads of the audio amplifier (the smaller surface mount chip) with an insulated tool - a toothpick would work.? If the audio level changes then you have a bad solder connection.

I was in Test Mode and when I hit M1 on either radio the radio would swing wildly in/out of transmit but I could not hear any audio (monitor was turned up) and still no rx audio.? I tried rebooting the radios with the same thing happening. Finally after a while I found that the PTT was held low by my SO2R Box to both radios.? Rebooting the SO2R Box fixed the problem.?
?
Now tonight Nov 14 I had this happen:
?
I was in a little bit of a hurry tonight getting things turned on and then ran into a big problem.? Whenever I would key a radio they would go into transmit and not come out.? I ran into this thing last week before the SSB Sprint and corrected it by rebooting the? SO2R box but this time it didn't work.? I guess I will have to reflash my SO2R box

W6FB replied:
I had this issue with my SO2R+ box a few weeks ago. I believe it was caused by killing power on the box instead of flipping the front panel power switch to off.
The solution was to bring up the SO2R Utility and reset the box, which resets the eeprom to default values. It worked until the next time I powered it off by?
killing the main +12V supply. I again reset the EEPROM with the utility and it has worked fine ever since.?
?
I learned my lesson, I now power it on and off with the front power switch, then when it is off, power off the main 12V supply.

So before I reflash is there anything I should look for using the utility so I can pinpoint what happened?? I have always just killed power and I have not used the switch on the SO2R Box.

This leads to a few questions - when is EEPROM written? Are there triggers, if so, what?
I have a specific sequence for powering off my station - Power off the K3s (both with KIO3As), then power off the supplies. I have two Astron 35A linear supplies, one for each K3 station, which includes KPA500 and KAT500, BPFs, etc. The supplies are wire-ORed using a 20A dual schottky diode device which allows for either supply to power the common devices. The output of this device feeds power to the SO2R+ box, Elecraft W2 Power/SWR box and a few other things.? Since most things are powered down before the SO2R+ box, it makes sense that there is a very slow voltage decay.
I have had very few issues with the SO2R+ box for many years until just a few months ago, which is about the time I actually started using it in SO2R mode. The problem manifested itself as Mike describes, SO2R+ unit holding PTT low, but to just one radio. Using the SO2R+ utility to reset EEPROM fixed it both times it occurred. I changed my power-down process to switch off the SO2R+ box when I power off the K3s, and have not seen a recurrence since.
If you need some testing done, I am willing, but not until after CW WW.?
