The ubiquitous Ameritron non-QSK amplifiers use open frame relays that (according to the instruction manuals) take approximately 15 ms to change states. I've been switching my AL-80B with a PTT signal generated by a microHam CW Keyer, with the PTT lead time set for 18-20 ms.
It seems to me the 20 ms maximum delay for the K3 was a pretty good choice. 73, Chuck Guenther NI0C K2/10 s/n 5853 K3/100 coming soon _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
