[Elecraft] K3s and ICOM IC-2KL

[German Duran]

Hi Christian. I'm using the 2KL with my Elecraft K3s and works well. But it
does not work automatically. When I change the band on the Elecraft I have
to change the band manually on the AT500 and 2 KL because the AT500 and 2KL
does it automatically. I think with the 2KL it is easy to change
automatically because they changes with voltage and not with codes like
Icom and Kenwood amplifiers that change with codes and not with voltages. I
am neither an electronic engineer nor a technician. I am a doctor and it is
difficult for me to modify the 2KL. I keep waiting for your news to see if
you can automatically change the bands in 2KL with your modifications. 73,
German
