Satellites, Transverters, and a Flex

I’ve been combing through many of the community posts and have a decent sense of what’s required for satellite operation. I think I may already know the answer, but I wanted to confirm with the community.

From what I understand, the Flex 8400 has only one XVTR port, which means it can’t operate in full-duplex mode on its own. To achieve true full-duplex cross-band operation, I’d need a Flex 8600 and two separate transverters — one for uplink and one for downlink.

Unfortunately, I overlooked this limitation when I bought my 8400. At this point, it seems like upgrading the Flex and buying transverters might not be the most cost-effective path. I’m starting to think that purchasing a second radio dedicated to satellite operation could be the better option.

I’d really appreciate hearing some thoughts or advice from others who have been down this road.

    My understanding is that, while the 8400 indeed has only one transverter jack , the radio is capable of full duplex operation. The single SCU limitation means it can only receive on one antenna at a time.

    Hey Neil, thank you for responding, I suppose that would not be a problem to only receive on one antenna at a time since the up and down links are typically on different bands?

    So if I use the below Q5 transverter, the 8400 will still work.

    I believe that there is a way to daisy chain Q5 transverters. You might want to check with them to see if that can solve your problem.
