[Elecraft] om2500a

[Ralf Wilhelm]

Hi Chris,

Am no expert (have no k3 and no om2500a)  but I was courious and checked both manuals.
My understanding is that you (or Elecraft) don't "want" the ALC and the keying of the amp is not done via Elecraft's PIN 10.

So, you would key the amp via the Keyout jack of the K3, connect amp's pin 4 to Elecraft's Pin 7 (tx inh), amp's pin15 to Elecraft's pin 5 (gnd) and that's it?.

You will have to turn on the tx inh in the menu of the K3. 

Maybe that is identical to your own guess or someone on the list can confirm this.

Greetings

Ralf, DL6OAP
