Fixed it! It was a bad cap in the control head. The spare head I used to check the radio had the same defect which steered me the wrong direction. (@#$^%%^!!!) C29 is a 22uf 16 volt electrolytic. It had leaked and corroded away the trace that goes from pin 4 of the 5 volt regulator to pin 72 in the ...

It does act like a shorted cap. Today I turned it on after being under my desk for a week. It came on and worked fine for several minutes before going into shutdown. It acts like when the cap is charging it's okay until it's charged then it shorts. I do have a schematic so I'll start looking.

I also have one of those Canadian radios. It was brand new still packed in the boxes and plastic wrap. Those are the low band split models, 136-156Mhz. Mine won't do over 158 either and that's just the way those are.

It won't display program, it won't read or write. I have had some of these that forgot their programming but this one has me stumped. It shows the proper channel for maybe a second when first powered up then goes blank. If I reboot it it won't show anything. If I leave it off for a awhile it will ag...

After less than a second the display goes blank and only the backlight stays on. No transmit or receive. I swapped control heads and no change. I checked for voltages ...

Are you using SP tune mode to enter ham freqs by chance? If so it will say model mismatch. Just ignore the error and proceed.

TK330 programmer
Anyone have a diagram for a programmer for the TK-230/330 portables? I built one from a schematic I found at mods.dk but the darn thing won't work.
