Maybe a web controlled appliance plug? I have one that operates a dehumidifier that I can operate with an app on my iPhone. Use something like that that has a relay inside - just wire it up for your amp main.

Unfortunately for me, I am trying to operate remotely. I may just have to get a web switch and turn the amp on and off. I am hoping that some one has a better solution.

My 2 Meter amplifier has a remote head that has the keying input located on the back of it. I opened it up and wired a toggle switch in line with the circuit with an LED. I labeled it STBY/OPR like on my Ameritron AL-1200. I just flip the 2 meter amp "out" of the PTT circuit when I'm not using it.

Initially I had the amp connected to PTT-out but that would key the 2m amp if I transmitted on any band. To help with this, I put the optional jumper on P8 in the transverter so that it put out 5v on ant3 (2m out) while transmitting. I then built a simple NPN grounded emitter circuit to key the 2m amp by grounding its PTT-in when 5v show up on output of the transverter. Here is the shocker: 5v show up on 2m transverter out whenever I transmit on ANY band. How disappointing. Am I missing something? Is there a simple fix?
