help with Icom IC706MKIIG	Reply

Every time I press the "Press-to-talk" button on my microphone the transceiver shifts frequency. What am I doing wrong?

How much does it shift and what mode are you on? I can think of several reasons why this would happen (repeater shift, being on CW instead of SSB, and having the radio set to split frequency mode are the three I can think of) Dan

Dan; I am in FM mode and the frequency shift is like from 146.940 to 146.950 and if I press the mic button agai it goes to 146.960. I don't know if I am in split frequency or not. How do I check that

Is that all it does? Every time you press it, it doesn't try to go into transmit but it just goes up another click in frequency?

From the other thread, to check if you're in split. "It sounds to me like you have the split frequency button on (SPL on the M1 menu). --Dale, K4EQ" I looked at the manual... check to make sure your "up" button isn't stuck or shorted. You might want to look at Page 8 of the owner's manual. The hand mic is wired strangely such that the switch that grounds the PTT line when you press PTT also switches the grounds to the up and down buttons. PDF manual here if you don't have it handy: http://www.icom.co.jp/manual/external/transceivers/IC-706MK2G.pdf Don't know if that gives you any clues, but it seems possible that the PTT and UP/DOWN could easily interact if some wires got crossed or buttons got stuck.

is it the repeater shift you are looking at?? typipycally the offset on 2 m is 600k, so if you listen on 147.33 the transmitter will be on 147.93, and some repeaters use a non standard shift. you have 3 modes in fm, + 600, - 600, and simplex. ( 0 offset) if you have other modes you can run split on hf or offset 700 or so on cw. check your settings.

"I am in FM mode and the frequency shift is like from 146.940 to 146.950 and if I press the mic button agai it goes to 146.960." You're not in split, because if you were, then every time you let off the PTT button, you would go back to your original frequency of 146.940. It would start there, go to the other frequency when you key the mic, then go back to the original frequency when you let up. It would do that over and over. It's also not the repeater offset, because other than the fact that the split would be greater, it would still work exactly the same as working split - start at one freq, freq would change a certain amount when you key up, then you'd go back to your original freq when you let up on the mic button. If I were you, I'd try a total reset and see if that helps. Unless you've been re-wiring the mic or something, I bet that resetting the radio will help.

You already been giver the FM offset, but the other thing that does this is split operation (Tx on one VFO, Rx on the other). Alan, KØBG www.k0bg.com

"I am in FM mode and the frequency shift is like from 146.940 to 146.950 and if I press the mic button agai it goes to 146.960." ----------------------------------------------------- Split and repeater offset DOES NOT do this. I don't know of any setting on the radio that would do this. It sounds like a problem with the radio. First I would try a full reset of the processor. Next you might try a different microphone. The mike up/down buttons will cause the frequency to go up or down - maybe there is some interaction between these buttons and the PTT button.

What most responders seem to be missing from his later post is that the freqency keeps "walking" up the band by 10KHz with every PTT button press.
