TX Delay

I received a report of what seemed to be hot switching artifacts when
running QSK with my SPE 2K amp. The K3S was set for the default TX Delay
but the friend who reported the issue later found an email from Wayne
indicating there was some issue with the default TX Delay of 8ms actually
being more like 5ms which would explain the issue.

I've not seen anything more about this and wonder if I've missed something
or Elecraft still working on it?

In the interim I've increased the value from 8ms to 11ms which should put it
in line with the actual 8ms default.

Pete, W1RM

Re: TX Delay

I haven’t tested it, but I recall that the delay is shortened if you use QRQ mode. With the K3S synthesizer, you really don’t need QRQ mode for reasonable hand sending speeds, so turn it off in the menu.

Re: TX Delay

Thanks Vic. I put in a query to Elecraft support about it and am awaiting their reply.

I may have accidentally put the K3S into QRQ mode but my 35 wpm sending hardly qualifies as that.

Re: TX Delay

There used to be a problem with the K3 before the updated synthesizer came out; at just around 30 wpm the keying would start to sound erratic. But with the new synthesizer installed in a K3, or a K3S, there’s no problem at any speed I can send at, even with QRQ mode off.
