The old tube rigs and their frame relay T/R are famous for glitching the leading edge of the first dit or syllable. The problem with arcs is that the arc is not just composed of the single frequency that is creating. The broad signal resulting from the arc will be very highly invested with off-band components There are many faults in the olde stuffe that usually need cleaning up to run smoothly with modern stuff, with the modern expectations.
I never had a KAT500 to go with my Yaesu FT101ZD. I also had to use a foot switch for T/R. 73, Guy On Sat, Oct 25, 2014 at 3:45 PM, Don Wilhelm <w3...@embarqmail.com> wrote: > Eric, > > What is the chance that the transceiver and amplifier are 'spiking' at > keydown time.
