If Elecraft could add a menu item that allows the user to select from a list of delay times, including the current value set as a default, then everyone would be happy and not have to make hardware changes to their amps and those with faster amps won't have to do a thing. I for one am not blaming Elecraft for the deficiencies of my amp, but am just asking if they could modify the firmware in the K3 to allow me and others to select from various delay times. So far there's been no response from Elecraft concerning this subject after a few days of discussion on this list. We don't even know if they could easily make the modification in the firmware. If they decide to respond to this issue and say they won't or can't do it then I'll be glad to look for a hardware modification to my amp.

I think the problem is not elecraft rigs but amplifiers that have unreasonably slow switching times. 10msec or longer is unreasonably slow and I think it's 'unreasonable' to blame the manufacturer of the radio because the amp manufacturer saved a few bucks and used a cheap, slow relay instead of a proper RF relay. None of my Icoms give me the ability to alter the key delay for slow amplifiers either. The correct approach is to mod the amp to improve matters. the other option is to use the PTT input with a footswitch to take care of RX/TX changeover 73 Brendan EI6IZ _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
