Hi Dimitry,

I strongly agree. I HATE foot switches, because I'm very poorly 
coordinated. :) I've never used anything but VOX in my own station for 
any mode, and I do RTTY, CW, and SSB contesting, run FT8, JT65, JT9, 
MSK144 for small signal work. With every rig I've owned since 2003 (when 
I had time to back on the air) I've been able to set the delay between 
transmitted RF and the DC signal to pull in the TR relay for a power amp 
to the value that my amps have needed. The high quality, well designed 
amps I've used have never needed more than 8 msec.

That's me. Everyone is different. :)

73, Jim K9YC
