PowerGenius XL Tuner: Will it be SO2R as well?

Will the matching tuner for the PowerGenius amp be SO2R as well, or will SO2R require 2 separate tuners?

Thanks

Good question! Technically possible since SPE can do it with the built in tuner in their amps. Once the memories are set, QSy is very quick.

The way Flex plans things, I'm sure this and many others were thought out....

As I understand it based on a conversation I had at the Orlando Hamcation the answer is the tuner is not really set up to be for SO2R.   The tuner will be exceptionally quick in changing frequencies however in an ideal SO2R situation you want two bands tuned at the same time and the tuner only has a single tuning circuit.  Another thing is don't expect it to load up the bed springs on all bands.   It will have a decent tuning range and the number I heard was about 8:1 or so. This is however a lot better than the tuner in my SPE 2K-FA.  It is designed for 3:1 on 160-10 meters and 2.5:1 on 6 meters with a loss of up to 0.8 db in the tuner.  My station has resonant dipoles on 160 through 40 meters and the amp has problems when you get near the band edges on 160 and 80.   Because of this, I also own a Palstar HF-Auto and have put the SPE in bypass mode. Although it is a lot slower the Palstar has a similar tuning range to what the new PowerGenius tuner is going to have and has no problems covering the entire band. Typical tuning time for the Palstar after the frequencies are set is less than 10 seconds.

      The Palstar is great.  The big difference (If I understand correctly) is that the genius tuner
is meant to be mounted at the antenna.

The "tuner" is actually an antenna coupler and is intended to be used as close to the antenna feed point as possible.  Although it can be used at any location along the feedline; even at the amp itself.  It will have a remote control head for control of the device.

But as Rick pointed out, having your matching device near the amp matches the coax and the antenna.  Depending on the extent of the mismatch, there will still be high losses along the coax and that results in energy dissipation as heat, not RF energy.  Placing an antenna coupler at the antenna feedpoint ensures that most of your RF energy is transmitted as actual RF and the amp is presented a nice 50-ohm that matches very well.

This antenna coupler, is it a 4O3A device or from some other company?  Could not find it on the 4O3A web site.  Can someone kindly point me to a link for this coupler.  Always interested in tuning an antenna at the feedpoint....

It will be from 4O3A.  It is not available for purchase at this time.

Ned, you are correct about the location of the tuner and that is really where you want it to be to reduce mismatch losses in the coax feeding the antenna.   If I'm remembering correctly it will have a control head that is connected to the radio/amp by ethernet and the control head will communicate with the actual tuner over the coax feed line.

By the way, you can also remote the HF-Auto with their rather pricey control head or by using the control program written by W1TR.

Having the ability to mount the actual tuner out at the antenna would be great.  In my current situation I just need to flatten the swr a bit for full output power.  I'll mount the tuner here in the shack as I have multiple antennas located on different towers.

I already have the 8x2 Antenna genius along with a set of 4O3A band pass filters and the triplexer.  All the feed lines come to the shack which is why I would need the tuner here next to the operating position.

Not sure why the pic's are sideways.....

SOooo  even with an Antenna Genius the new "Tuner" will connect to either Port A or Port B of the 8X2 antenna genius switch at the shack end.....  OR it will be remote located at the antenna of choice selected by Port A or Port B of the Antenna Genius?

Unless it's setup like the Powergenius, 2 inputs and 2 outputs.

Ah.. OK..  I thought thats what you asked originally but did not see the definate answer.   That is actually what I was expecting on the tuner..  2 inputs from the Amp and 2 outputs to the 8X2 Antenna switch.

Tim states that it will be one input and two outputs: https://community.flexradio.com/flexr...

The plan as I understand it is for the tuner to have only one input and and I believe only one output. The idea being that the AntennaGenius or some other switching system would be use to control which antenna is used.  With each device doing a specific task you will have a the maximum in flexibility in your setup.
