FlexRadio 4o3a Tuner Genius XL is headed to production

FlexRadio Systems sent out an update on the Flex-TGXL (Tuner Genius XL) which initially will launch in two forms – a 1×3 matrix (one input and three antenna outputs) and very interestingly an unique SO2R version (two separate radio inputs, each matched to a specific single output).

Preliminary View of the Flex-PGXL Tuner

Those of us with Flex-TGXL pre-purchased as part of being an early adopter of the Flex-PGXL Amp, received a survey where we were asked which version we wanted, or if we would rather have an Antenna Genius switch. I’ve elected the SO2R version for my selections.

Some interesting preliminary information:

Range – 160 to 6 meters (continuous)
Interfaces – FlexRadio LAN, RS-232, CI-V, BCD, PTB (Pin-to-Band), or built-in Frequency Counter.
Matching Range – up to 10:1 SWR
Tuning Time – New Solution 2-12 seconds, Stored Memory Solution 20ms (!!)
Power Rating – 2000 watts at 100% ICAS Duty Cycle
Display – 7 inch touch screen
Power Requirements – 15-26 VDC @ 2 Amp, power supply included
Min/Max Tuning Power – 10 watt min, 200 watt max
Operation – Fully Automatic or Manually Tuned
Rough Dimensions – 12″ wide x 6″ high x 14″ deep (to be confirmed as the spec sheet is a bit confusing)
Weight – 15-1/2 Lbs
Connectivity – Requires a CAT5 cable to connect to your LAN for FlexRadio integration

Preliminary View of Flex-PGXL Tuner

Pricing has not been announced. Everything is a preliminary information release.

This Flex-TGXL is a 4o3a/FRS project and most likely will be built in Montenegro at 4o3a’s facilities.

I’m excited!

    SO2R versus 1inx3out TGXL version debate

    Placed my preference back in Sept 2020 for the1inx3out TGXL version with FRS

    Never operated SO2R but have a 6600M and PGXL ( acquired over 3 years ago )

    My Bands are 40 meter dipole with a 20meter thru 6meters using a HexBeam
    Use my radio remote with a Palstar HF Auto for now

    Thought 3 Bands Remotely would be good if I want to use 3 different antennas like with I do with the Palstar HF Auto

    Been on the fence in trying to decide if SO2R is

    Do not use 2 Bands at same time with My HF

    I chase some DX but not in 24hr DX contests

    What are your thoughts Steve

    Hi Mike WB6DJI

    You pose a good question.

    I’ll have a post on this soon, and it seems to depend more on operating style and where in the feed line path you might be using antenna switches.

    More in the post to follow in the next fews days, as I want to organize my thoughts coherently before I share them.
