Transverter question RX and Tx lines

  • Updated 8 months ago
A few years ago, I did a lot of EME on 144, 432 and 1296, and that was before my Flexradio days.
My question is as follows;
I will be using a  Kuhne transverter on 144 that has an input for a tx input line and an Rx output line. That then will be fed to coaxial relays and a low noise preamp at the antenna. 

I can see how I get the low level tx output from the 6700 or the 6500,on 28mhz, using the transverter plug,
So I need 2 lines from the 6700/6500, so where do I get the rx back into the 6700/6500?
Do I use connectors 20/21 or  22/23 and if so how do I use them.

Thanks
Ross

Ross, this is quite thoroughly covered in the Flex-6000 Hardware Reference manual and the SmartSDR Software User Guide. You will probably have to read both of the manuals to get the full picture for connecting and configuring a transverter. The Flex is actually designed for a single port transverter, where both transmit and receive are on a common line that connects to the transverter port, but there are instructions for using a two-port transverter like yours as well.

You can get the rx back to the 6700/6500 by connecting to RX A or RX B BNC ports on the back.  In Smart SDR you just select which one you are using under the Blue RX antenna option (Red is the TX antenna) above the freq readout at the top of the slice your using.

You can also use the preamps located under the ANT box on the left of the SmartSDR screen should you desire.

Thanks for the advice, Am I correct in assuming by your reference to RXA and RXB ports these are the ones referred to in the hardware manual, and are shown on the details of the rear panel as SCU-A  or SCU-B?

Thanks
