[Elecraft] Acom Amps

[Brendan Minish]

I have never had a hot switching issue with the K2, the timing is more
than adequate even with TR set to 0 
I have even tweaked my K2 for faster QSK 
Perhaps Wayne could comment on the timings but I have never seen an
issue here nor have I a problem with Keyclicks with either radio in QSK
mode with the Acom 1k. I have checked for clicks as they are most
annoying
BTW the 1000MP is not good in the click department if unmodified. 

The acom 1k's CPU controller will actually take the amp off line if it
detects hot switching
