I would like come back with possible issue on my F6700, since last month i am tried to use actively QSK on my F6700, unfortunately , in reference with https://community.flexradio.com/flexradio/topics/qsk-on-6700?topic-reply-list%5Bsettings%5D%5Bfilter... ,   i getting popping between character what assume strong, plus I am hearing very weak relay click in tact with my CW keying,  this is audible(but weak) with TX=ANT1, RX=(ANT2, RXA or RXB). Only combination where relay clicks inaudible is TX=Transverter port and RX = any other. Somebody who owner of F6700 can check this behavior for me ? 
In case usage QSK with PIN diodes  or different RX/TX ports should be no relays switching at all.This is a issue only of my radio or some other behavior?

    The pin diode switching is actually audible if you are listening closely enough.  I can't tell from your description whether this is what you are hearing or not.  If it is much quieter in CW than it is in SSB, then you are probably hearing the pin diode (sounds like a higher pitched 'ping' than the normal 'clack' of the other relays).

    We have done some significant work on CW over the last few months.  Stay tuned and give v1.9 a try when it is released and let us know whether this improves things for you.

    Yeah Eric, i think you are right, this is not like strong relay click(ex: in case band switching or during radio start up) but higher pitched 'ping' what audible untill speed ~85WPM in tact with CW keying where afterward (over ~85) no swithcing with every CW  what visible on the waterfall like uninterrupted transmission with some flashes periodically(i assume SW case) and  i see sounds very good : "We have done some significant work on CW over the last few months" - very pleasant wait for ability work QSK at 40-50wpm
