Icom F510 TX Problem

[stuartm34]

Please help me with this.

I have an Icom f510, which after a forum strand on here I managed to get transmitting. I have today had to reprogram it updating the frequencies.

Now the radio will receive when on the correct channel, but pushing the PTT results in the radio returning to channel 1 (the priority A channel) and does not transmit. This happens even after opening a fresh programming file and loading that.

It's happened to me before and the answer was to turn off the EXO option, I can confirm this time that EXO is off but the error is still occuring.

I now know thanks to an email from Icom, that this is a problem with the firmware installed, I can't really afford to risk not having the radio operational again this week, any chance there is anyone on the forum that can advise me on how to update the firmware?

Did you ever find out about upgrading the firmware?

I've got a very similar problem, my Icom IC-F510 receives just fine but as soon as I key the mic, it shifts back to bank1-ch1 (which I don't have set as either priority or emergency) and there is no TX output on the frequency.

However if I set the radio onto bank1-ch1 and then *double* click the PTT it transmits just fine with good power and audio reported.

Any help or ideas would be gratefully received.

hi all, my problem is almost like yours. RX on ham frequency works fine,but if i trying puch PTT - not transmitting. I tryed use same russian people maked .icf file with their configuration - same effect,RX good, but cant TX... Btw what is EXO option?

I believe its to do with controlling an external alarm.....

EXO/Horn— EXO : Selects the optional OPC-617 HORN terminal (pin 6) condition when receiving the matched 5-tone or Status call. An external buzzer, horn honk, etc., can be controlled with this setting.

ON : Goes to ground when receiving a matched 5-tone code.
OFF : No function.

Changing the setting made no difference to my radio

I think I may have just figured it out.

I opened a totally new 2-TONE config, added a couple of simplex ham frequencies to some channels in bank 1 and had the same problem, RX fine but no TX at all.

I then changed the 2-TONE setting from OFF to 1 in the Bank/Channel config for each channel and resent the config to the radio and bingo TX now working.

hi Netwisdom, could you explain me or show print screen where you changed from off to 1. Thanks

This is what I did to get TX working...

1. Set the radio model as LMR(2Tone)
2. Configure a channel in BANK1 with frequency, power etc etc
3. Under 2Tone heading (between Auto-Reset and Log columns) change it from OFF to 1
