[Elecraft] Driving an external amp with base K2
I am trying to drive an external amp, 300W amp, with my base QRP K2. The issue I am having is that during SSB mode transmissions, the amp's T/R switch often opens and closes between the sylables of some words. Is there an adjustment I can make in the K2 to help lessen this? Otherwise, it seems to working well. Also, when working with such an amp with CW, should it be set for AM mode? 73, Bill - WA5PB ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Why don't you use a manual keying line instead of using the rf sampling keying. Gregg R.

To the best of my knowledge, the amp does not have an external keying line available. 73, Bill - WA5PB -Original Message- From: Gregg R.

Re: [Elecraft] Driving an external amp with base K2
It's easy enough to create one and put a switch in to turn the sense circuit on and off. I've done this on many amps, especially on VHF/UHF amps to cure this SSB problem. Gregg R.
