I have a K2 and added the Elecraft transverter interface using split rx/tx. I am using 28 MHZ as an If and use only TRansverter 1 on the menu. I am using 50/144/222/432 DEM transverters with split lines out using an external switch. The K2 drives the transverters fine but on RX I can hear strong 144 MHZ signals even thought I am on 222. For switching I built a DEM IF switch(no longer sold). It uses a switch and an IF amp on TX &RX plus pots to balance out the power/gain. At first I thought the problem was in the DEM switching box because of the IF amplification and the use of a switch as opposed to a relay. I Then built up a switching box using good isolation relays made by Dow Key microwave. (2) SP4T are used and controlled by a 2P4T switch which also switches the contoll/PTT line but the problem still exists. Has anyone else experienced this problem while using the Elecraft transverter interface?
