WTD: Schematic or link to online source for same Kenwood TM261A
Per the subject line or would like to talk to anyone who is familiar
with the memory or mode control of the memory or processor in this radio. I'm looking at a function "F" button (switch) that works (beeps and will cause a press-time-out) but doesn't otherwise effect any control. Gord VE1AJF |

I'm looking at a function "F" button (switch) that works (beeps and will cause a press-time-out) but doesn't otherwise effect any control. Sorry, no tech info, but a couple of thoughts. The fact that it beeps indicates that the key is being scanned, and that the microprocessor is running. When you way "Press timeout" do you mean that the "F" indicator lights, then goes out after an appropriate time out period of no activity. If so, this tells us that the key is being scanned correctly (interpreted as Function). If no "F" indicator, there may be a fault in the keyboard matrix which is causing the key to be interpreted as something else. Do all of the other keys work normally? If so, and the "F" indicator is lighting when you press Function, then it pretty much has to be a "software" issue, the microprocessor is not acting on the key properly. If other functions don't work, then the radio could be locked - Press F then LOCK (leftmost key iirc) to unlock it. If that't not it, try a full reset - hold MR while power-on, then release, and when you get "all segments on" on the LCD, press MR again. That should restore the radio to factory defaults (you will use you programmed memoryies etc.). Gord VE1AJF Dave VE3DRD -- dave06a@ Low-cost firmware development tools: www.dunfield.com dunfield.

Howdy Dave and thanks for the reply......at this point I've been sent a
schematic and am studying it. The current operational status of the radio is that it has programmed frequencies and the display is in CHANNEL mode and, as programmed, the radio transmits normally (including DTMF) and receives normally. I can't change the display however or enter into VFO mode. The rotary encoder works (just selects these channels). The MR or memory recall button only functions to activate a scan of the channels (by holding it in for 1sec). All pushbuttons indicate with a beep when pressed (and a second beep is emitted after approx 1.5 secs if held pressed). In reply to your questions......

Sounds to me, like you're missing a "lock out" command too. Check the manual
for such a function. You're probably right about the "Mic" lock switch, if it is as I've usually seen. "Gord S" wrote in message ...

Thanks for the reply radiosrfun! I don't believe this radio is in a
lock mode as I don't see the lock "key" symbol indicating on the lcd display (as it should indicate). It basically seems that the radio has one symptom which is that the Function key has no effect (other than to indicate that it's basically working by causing a beep when pressed). Having said that, I can not reset anything either so despite not indicating a LOCK condition, the processor doesn't seem to be re-configurable. radiosrfun wrote: Sounds to me, like you're missing a "lock out" command too.

Do you have the "owners" manual to do a "reset" - even though you said you
tried doing one? I looked for a copy of the manual - but - the one I found, all the pages weren't there. It was missing about the last 15 or so. I hope you can find the issue..... If someone has a "full" copy of the "owners" manual, "schematic" or "Service" manual, maybe some ideas can be tried. I'll look around, but hopefully others can hop in and help.

I do have the owners manual, so that I can see how the radio is supposed
to operate and be reset if desired. Nothing seems ambiguous to the instructions. This isn't my radio and was brought to my bench for the appearance of the problem as described - owner is competent in it's operation etc. Thanks for taking the time to reply so far! radiosrfun wrote: Do you have the "owners" manual to do a "reset" - even though you said you tried doing one?

Just wish I had a copy of the "Service Manual" to help more - but I
don't......... I'm sure they're out there - for the purchase - which is what it appears the next step "might" be. I don't know what else to suggest being I don't have any of the manuals here to refer to. Sorry "I" can't be of more help at the moment. Sometimes, it is a matter of overlooking the minor stuff - which is why I also asked if you had done that. I've been there and done that as I'm sure you and many other's have. IF I can come up with anymore info - I'll pass it along. Right now - without schematics, etc.... I'm in the dark too. Good luck! Just a sec...... Got to "Rec.Radio.Swap" - there was a guy - not sure if he floats in these groups or not - his name is Cliff. Used to have a Kenwood Shop. Ask for him - or post your query there - maybe he'll pick up on it and be able to give a hand. "Gord S" wrote in message ...
