Re: [Elecraft] Default K3 transmit delay may be too short for slow QRO amplifiers

My amplifier uses a reed relay and a vacuum relay for QSK. It uses the so-called "AG6K circuit" which supposedly makes the usual Jennings RJ1A relay operate in 2-3 ms. I never had any problems with the default delay of the K3, both before and after installing

With the Elecraft gear (starting with the K3), a sequencer can be started with the KEYOUT output and RF held off by TX INHibit until the sequencer completes. Of course, there are other methods, but to my mind, that is the most "automatic" method - you operate the transceiver as normal and it "ju

From experience, in an operation as you describe, a sequencer is almost mandatory to assure each item switches as it should and that proper feedback on that item to the sequencer to allow it to proceed to the next interval and switching.  I don't feel one can relay just on the radio to perform

The delay can be set from 8-20 ms at present. Given the small time offset, this is actually 5-17 ms (approx). Use small values if possible. With external keying, you can generally compensate by reducing the device’s weighting. Wayne http://www.elecraft.com > On Jun 8, 2018, at 5:02 AM
