FlexRadio 4o3a TGXL Tuner Genius Has Arrived! (Unboxing)

UPS delivered a long awaited addition to the K9ZW ham shack, arriving of course on the only day I was out of town.

I removed what I thought was the inner box from the big generic shipping box filled with packing beans, a box that UPS had roughed up a bit in transit. Final unboxing was deferred to Saturday June 19th 20201 as I wanted to put this tuner into use for some weekend work.

First a few unboxing photos:

Two models in the initial launch, an SO2R version at $2499 and a single-path 1-input-to-3-output version at $2199.

Early PGXL Power Genius Amp buyers who had a TGXL included in their early adopter package should receive their PGXLs by early summer, with new orders to follow.

Looking forward to receiving mine.

FlexRadio makes a TunerGenius XL annoucement

FlexRadio Systems 4o3a partnership project’s long await TGXL Tuner Genius XL is in final beta testing. At the recent online hamfest a video was launched:

Per FCC rule FlexRadio cannot take orders prior to FCC approval but they are collecting a list of interested parties.

To quote the FRS community:  Mack (W4AX) did an excellent job explaining the certification and shipment issues on his latest post on the Flex Forum:

Here’s the official word.

The TGXL’s have shipped.

I am running a very small Beta test to make sure they are rock solid.

I expect that to take three weeks. By then we will have the full FCC and CE certifications.

The first shipments will go to people who purchased a PGXL during the promotional period that included a free tuner.

We expect to clear that backlog not later than the end of June.

At that point shipments will begin to people who are on the wait list.

Firm orders will be taken as soon as we have the FCC and CE certifications.

TGXLs are being manufactured as quickly as possible.

There is a huge demand.

Mack W4AX
Program Manager

Nothing heard in years on the Alpha 4040 or the Kessler autotuners. I’m hoping to seem my PGXLs by summertime.

FlexRadio/4o3a TunerGenius XL – SO2R or 3-port version?

Last weekend Mike WB6DJI posted a very good question about the FlexRadio/4o3a TGXL TunerGenius and choosing between the two initial versions:

Steve
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
better

Do not use 2 Bands at same time with My HF
Remote

I chase some DX but not in 24hr DX contests
here

What are your thoughts Steve

Mike WB6DJI

 

Mike WB6DJI followed this up with an email, as he too like myself is trying to figure out which version would work best for our particular station setup.

So everyone is on the same page the SO2R version (Single Operator 2 Radios) is optimized to rapidly alternate between essentially two parallel RF paths. The paths are distinct and cannot cross. I’ve read a 20ms path-flip number, once each path is stored in memory.  When the radio is a multi-SCU (Spectral Capture Unit) FlexRadio (6700/6600) the single physical radio is well suited to take the place of both radios in the SO2R equation.

The 3-port version is optimized for a single RF path and basically has a 3-port antenna switch integrated into the tuner.  There needs to be a separate feed line from the three possible antennas, one to each designated port.  I’ve not picked out a specific switch time, but the same 5ms for solutions stored in memory would seem likely.

More on the FlexRadio/4o3a Tuner Genius XL

Recently 4o3a SkySat released a series of photographs of initial production Tuner Genius XL units by social media.

In their comments first production was reserved for Hams on “the list,” which likely reflects those who bought a PowerGenius XL/Tuner Genius XL combo.

I’ve not figured out if the photographed version is the SO2R model or the conventional tuner version.

Early look at the FlexRadio/4o3a Tuner Genius Prototype courtesy 4o3a

Beyond the photo and some general conjectures, I have nothing further to share, in respect to not being on the inside of this product’s development nor knowing anything that FRS said could be shared. 

On Facebook 4o3a shared a photo of a Tuner Genius prototype:

What I would share is a guess on my part:

As FRS and 4o3a have suggested that the Tuner Genius will likely come in several versions, do not expect that the fullest featured version is either shown in the picture or will be offered as the “premium” for the early adopter Power Genius Amp (PGXL) purchasers who are owed a tuner.

I can speak what I might do, as FRS has not spoken about what their plans are either in public or private, as I would offer the Tuner Genius in a no-faceplate version as an add-on to the PGXL amp, a stand-alone with faceplate version like the photo shows and a remote version where the matching circuit would be located at the tower base/antenna.  I would also offer a dual-version where several Tuner Geniuses could be slaved to each other to allow very rapid deployment.

To the PGXL early adopters would be offered the no-faceplate add-on version, with the option to buy-up to any of the more involved configurations.

But again that is my off the cuff idea and my only skin in the game is as an PGXL early adopter.
