Mastering SO2R & 2BSIQ with the FlexRadio 6600 & 8600 Series
For serious contesters, the pursuit of rate and multiplier efficiency is a never-ending journey. Traditional Single-Operator Two-Radio (SO2R) setups often require a mountain of external hardware: complex bandpass filter matrices, external audio switches, and intricate interlocking cabling to protect receivers. However, Software Defined Radio (SDR) technology has fundamentally transformed this landscape. Specifically, the FlexRadio 6600, 6700, and 8600 series offer powerful, integrated platforms capable of handling true SO2R and even Two-Bands Synchronized Interleaved QSOs (2BSIQ) with a remarkably streamlined hardware footprint.

Surely there's something cheaper than a goddamned #FlexRadio that could be connected to over a browser or similar, & let me stream the audio.
Like I have a #Tablo, lets me do this with broadcast TV. I want the radio equivalent.

I watched #DXCommander video about #QSODirector a while back. Impressed. Installed & tried it.
Now I'm wishing I could connect Linux machine to both FTdx3000 & RSPDuo & then present like it's a single IP-remote-able modern rig. Like a FlexRadio.

It is all bullshit. A grift. The gov't will pay 10x the price just to move money from taxpayers to contractor oligarchs.
Really, FlexRadio or Honeywell couldn't build a proper comm system??
