Icom 7610

Ok. I have a problem:


I am using both my Flex 6400 and and Icom 7610

I am going through the Expert 1.5 Linear. The 7610 is attached to the LAN. But when I key up, the tuner says 'NO PTT.' Can someone help me figure this out?

    My guess is the 7610 does not connect the PTT thru the LAN. You must connect a PTT cable from the rig to the tuner.

    That is what I am thinking. But then how to key the amplifier which requires at PTT, as well?

    Hi Cy, The tuner has a PTT In and a PTT Out. Connect the rig PTT out to the tuner PTT In, then connect the tuner PTT Out to the PTT in of the amp.

    I just did that and it did work. But now I am getting the same message. I will keep working on it.

    Do you have the PTT in and PTT out reversed on the tuner?

    no. from the send (icom) to the PTT in on the tuner

    So when I use lower power, it recognizes the PTT but when I turn it up, it doesn't and it is not keying the amp

    Ah... Sounds like RF getting in somewhere. I would put some ferrites on the PTT cables, but it could be coming on any line to the radio, tuner or amp. I have had very good luck with the mix 31 ferrites from Palomar Engineers.
