[Elecraft] [K2] Solutions for K2 Transverter Quirks

[Steve Kavanagh]

The K2 makes quite a nice IF rig for VHF transverters, but it has a few quirks, like most rigs.  I've put my solutions to two issues up at www.qsl.net/ve3sma/downloads.htm . 

First is a sequencer which switches the RF to the transverter to prevent it from transmitting while its internal antenna relay is switching.  This deals with the lack of any way to stop the K2 from transmitting on CW when the key is pressed.

The other is a bandpass filter which gets rid of most of the problems due to the high RF sensitivity of the transmit IF output circuitry to RF.

These are not extensive articles, but there should be enough there for knowledgeable hams to ccopy...or get ideas for better approaches.
