Author Topic: Latency returning to RX from XMT on FT-2000D using EQPlus:  (Read 2493 times)

 Huh    This weekend I ran an EQPlus with my brand new FT-2000D. Great results, but I noticed something that I haven't noticed before with other radios using the EQPlus: when I complete the transmission and released the PTT button, the RX (at least the AF output) doesn't bounce back immediately - there is a slight latency - sometimes even up to half a second or more - it's as if the XMT isn't finished - like when you have to wait after a VOX delay, but I'm not using VOX. At first I thought there was something wrong with the PTT button on my mic so I switched - same thing.

    I noticed this when I had the comp and noise gate pumped up pretty high on the EQplus - about 60% on both controls, and running the full 200 watts from the 2000D. Haven't tested without the EQPlus etc yet - need to do some more testing to zero in on the problem. Also sent an email to Julius about it. But I was wondering if anyone here had insight into this issue.

    I think I remember I had something like this a long time ago with an FT-900 that had problems leaking RF (no EQPlus) and there was a feedback loop that was oscillating and continuing after the PTT was released - but when that happened of course I had all kinds of other problems in the shack with RF getting into appliances, current in the mic, RF in my signal etc. But nothing like that now - signal is clean and clear and no side effects at all - haven't heard or felt anything that would suggest an RF problem.

    Thanks

Did you switch the AGC to "slow", or does the EQPlus do that?
