Hi Paul, Reset did it! Tnx.

Hi Mike, The microprocessor must be initialized with a programmer. So you can't plug in a blank microprocessor and install the firmware. Does the SO2R Box Utility communicate with the SO2R Box? If

I recently powered up my trusty old SO2R box. It lite up the TX1 red LED which is normal, but both Green LED's were on !?! If I flipped the RX selection switch from 1 to 2, the Green LED's both went

Tom, I hope it helps! Best of luck, Bob K5WA

Bob, 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??? Will pop the

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

Ahh, that makes sense. Thanks for the quick response! -Steve [email protected]> wrote:

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

Mike 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

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

Dennis, Thanks much. Right now I am not using Icom rigs but I remember that to a slight extent. I tried pushing on the audio IC and no improvement as Paul suggested. Going

Mike The original unit used 2502-4 ICs to do the keying and PTT. We replaced it with a TLP442 or similar to improve keying with Icom rigs. I may have some in the shack- I'll look later

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

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.

Hi Mike, It sounds like the SO2R Mini's Winkey was initialized improperly. Does it happen if you use it with a different program? If so I would re-flash it. Paul, K1XM

Paul, Another different problem developed tonight with the SO2R box and wonder if you have any isuggestions or have seen this before. Computer was set

Thank you will do. Good luck next week! Alex. AK1MD

I have not looked at the EEPROM code in several years. I will try to look after the CQ WW. Paul [email protected]> wrote:

Hi Alex, I think this issue is N1MM specific, and not related to the SO2R Box. You may get a better answer on the N1MM Logger reflector. Paul, DU1/K1XM [email protected]> wrote:
