Unless you operate from a fighter plane, I can't imagine any need to be concerned with this. Sitting on a less than sturdy desk, on tile floor at ground level, no vibration. I can't imagine issues

Re: QDX caution
That's essentially what JS8call is -- using the free text packets of the FT8 protocol for a more normal (albeit slow) QSO.

Re: QDX caution
There is something to be said about the +15 dB processing gain of FT8 and varying amounts with all of the JT modes. (or 25 dB if you compare to SSB). I actually am a ragchewer when I am able, which

Re: QDX caution
You can always use the 13 character free text mode of FT8 to have a regular (non-contest) QSO at about the equivalent of 5 WPM. ?Just pick a clear frequency well away from the usual FT4/8 watering

Re: QDX caution
Well Dave, I'm 33 and I am pretty immune to it.? I tried it a couple times a couple years ago... not my thing.? I like JS8 Call but not FT8.? The QDX can be used for more than just FT8 though.

Re: QDX caution
I must be old enough to be immune to FT8, etc. Built two digital xcvrs, played with them during the winter in Florida a year ago, got bored and have both ready to be given away to any club member.

If you use silicone try to find the "neutral cure" type, which does not emit (as much of) the vinegar-smelling fumes when it cures.

Re: QDX caution
Agreed. I like FT4 as well for the points you make. I think making FT4 a bit different by adding a "contest field" would be interesting. For example, this weekend there were stations calling CQ LCT on
