I don't know Chris.  Have you downloaded and compared the FCC report from the SPE 1.3k-FA to see if there's a difference or the same?

Hi Guys... Let's not get too excited about things like this.  Patience.  :)

I believe that the FCC requires that all amplifiers have zero gain from 26 to 28 MHz.

Howard is 100% correct.

So a properly certificated amp will have zero gain on 28.00000000000000000000000 MHz. 

It will have gain on 28.010MHz. If you are an amateur licensee you will not be transmitting exactly on 28.0 MHz. That would put you outside of the legal band and I am pretty sure the stock Flex TURF would not allow it...

The FCC has some strict rules to prevent CB amps. This is one of them. If you've had one of them in your neighborhood tearing up your TV late night because he's talking to skipland you'll appreciate it.

Ria, you are correct. It is just a banal mistake in FCC report. I will send comment to Lab. PGXL does not operate from 26MHz to 27.999 MHz, due to FCC rules.

Did we ever get a ruling on getting rid of the 15db gain rule that was before the fcc last year?

No ruling yet, only a denial of the waiver request that was requested by expert linears.

One thing I do not like is that on 6 meters it needs more than 100 watts to get 1.5kw out. Hopefully that will change.

Ria,

I suspect that the input padding attenuation will change with each band selected. All that would be needed is to reduce the input attenuation on 6 meters. Then the drive would be adequate to see 1.5 KW out across the band.Flex and 403A are chock full of smart guys. We will see 1.5 KW out with a lot less than 100 watts drive on 6 meters, I am sure.

Like a small capacitor across one of the resistors on the input attenuator would
help drive Power XL Amp to get Full Power at 6meters

Same thing with 20 meters. qpp warr drive.

Again this was a very early unit and a lot of things have probably changed since then

Can you change a device after FCC approval ? No need for new approval?

If yes, it's easy for every to get FCC :-)

I don't know how are the rules at FCC

Most Flex Radio's do about 85 Watts to 90 Watts output Power
but with needing 100 Watts output drive can only 
guess Pout will be less than 1.5Kw on some bands :-(
13V versus 14.2V at DC Plug of most Flex6xxx radio's

My 2K-FA puts out 2.2Kw to 2.4Kw all Bands except with 6meters 
with 2Kw Maximum Output but use it solidly at 1.5Kw output
to keep it cool since it's a massive amplifier in size and heavy in
weight compared to others.

Still Prefer the Power Genius since it's Plug N Play with SmartLink 
and v2.0.xx SSDR with remote ability, hopefully they can tweak it
a little so Maximum drive can be less than 100 watts ( say 80 Watts)
and very small in size and light in weight !


My 2K-FA only needs 30 to 35 Watts for 1.5Kw out on all
bands

We need 6-7W, and we have 10dB att in between radio and AMP due FCC restriction. Unit which will be ship soon needs a bit less than 100W. EU model will be with 10W of drive for full power.
We deliver first units for 3Y0Z and this month we will start to ship pre-orders to Flex.

So, the amps headed for the States will need near 100w to drive them to full power?

Based on this I don’t think anyone has anything to worry about.

Here are the first two for UPS pickup leaving today for 3Y0Z via Atlanta.  No problem making 1.5 kW on all bands.  100W drive is required on 6m.

Nice to read that Flex is back in race after changing from Flex PA to Acom PA :-)

The original press release when Acom was contacted to supply amps to Bouvet had said that Flex was still going to supply two PAs and Acom was going to supply the rest (manual tune PAs). So that has not changed. Those are the two of them.

Is there any publication about the IMD3 values of Flex6 from OUT=1W till OUT= max. ?

Also what max. power output on each band at 50 Ohm (not antenna) are possible?

I will most gladly accept the delivery of anyone's new Power Genius XL amplifier for testing in the harsh environment created by having WWV in my backyard.  I'll put your new amp through its paces for a period of one year or until someone else sends me their Power Genius XL amplifier as a replacement for the test.

I will cover return shipping in the original containers and boxes.  Your unit will be as good a new, just carefully broken in and adapted to the high RF environment in Fort Collins.

I offer this service absolutely free of charge.  Just email and I'll give you my shipping address!  Each month you'll received a detailed report of the frequencies and power levels that your amplifier was asked to work on/at along with detailed opinions of performance as I put it through its paces on a daily basis.  Again... you get all of this free.  The only cost involved is the shipping to my QTH.  As specified above I will pay for the return shipping.

This is a deal you cannot pass up!  Your amplifier gets broken in, characterized and used in a difficult RF environment.  You'll have much more confidence once it returns back to your shack that it will meet your needs.

Email for further info on this special offer!
