    Okay just recently checked my 7300 and seems I don't have a problem with overshoot but I do have just over 4.3ms of RF after the amplifier send line opens. I also see there is a DC shift on the RF out but that might be just in my DSO I'll look into that. But there doesn't seem to be an acknowledgement of the issue or a fix as yet.

    I haven't used the 7300 on my amplifier a KPA500 yet, currently using my 991A whose timings are correct.

    I't would be easy enough to kludge as mentioned above or use the relay timing from the relay used for PA switching but would prefer a fix from ICOM

    Everybody with a 7300 does ! (and the 9700 has too)
