With the K4D having two very good receivers I purchased a 2nd transverter from Kuhne. This was a small MKU 432 G2 that sits inside the the instrument case on the top left of this picture. Unlike its big brother it can not be clocked of the Rubium 10Mhz reference and does not have a PA or sequencer.

The TR 432H Transverter drives the A receiver for H -pol RX and the new MKU 432 drives the B receiver for V-pol RX in the K4D. I find the combination of the Kuhne Transverters and K4D receivers offer excellent performance.

In the instrument case (on the left in the photo) along with the V-pol Transverter are four W6PQL FET switches used with the TR434H sequencer outputs. The FET switches drive the Mute, Antenna Relays. LNA 12V and PTT to the HLV-1470 PA.
I can turn the LNAs and V-pol Transverter ON/ OFF from the front panel switches

Distribution & Control Box
The instrument case really acts as a distribution box for the shack and keeps things tidy.
The box terminates the control cable to the control box (relays & LNA) up the mast, TR432H control cable, HF loop relay, K4D PTT selection to HLV-1470 70cm or SPE 1.5K HF PAs and the TX relay which selects V or H pol transmit.
