Re: [Elecraft] K2 TUNE power reduction without ATU installed .

To Dave and Mike I must hold my hands up and admit to starting a  " wild goose chase " . I had misinterpreted the manual and  convinced myself that the power reduction when pressing TUNE relied on an ATU being installed ... I had even proved it to myself ... if I did a TUNE at 25W , it di

Hi Steve, There is no documented method to set a lower TUNE power when a non-Elecraft external ATU is used or when no external matching unit is present. The TUNE button on the K2 keys the transmitter at the requested TX power set by the POWER control, e.g. 100 watts, in the absence of a connected
