[Elecraft] k3 no RF in transmit

Fri Dec 4 13:26:36 EST 2020

I concur with this statement.  

For instance, SGC makes "smartuners" that can be remotely mounted from your transceiver.  These tuners work automatically to tune the antenna when a transmission occurs.  The long press on the XMIT button function transmits a low power continuous tune sufficient to activate the SGC tuner's tuning function.

The ATU tune works with the internal tuner.

You've made a mistake, a long XMIT (TUN) press is for applying a small amount of output, to match with the antenna (or check the SWR).

ATU TUN (ATU) applies power to the internal tuner, if any, if enabled. Two different functions.
