[RFI] When you absolutely positively have to generate 1.5k of QRM

[Roger (K8RI)]

Perfectly legal as far as I can see. It would need approval were it 
being sold as a complete amp. Even then, I see no problem getting that 
approval except for possibly gain which could be easily met and the 
increased price.  Spectral purity?  Probably good, but with dynamic 
predistortoion and run at half its ratings it most likely would be 
great.   A couple of those surplus  50 - 60 Amp Power Supplies at less 
than $50 or $60 ea and that leaves the LP filter, band selection 
circuitry, and cabinet.

It is not a complete amplifier. It is simply a component and the FCC 
would see it as that.  The required LP filter would probably cost more 
than this component. For a nice clean signal I'd want to run a pair of 
them at half the rated power into a combiner.  A combiner and LP filter 
to handle 2 KW might run as much as two of these amps. Then you need a 
capable  PS so in total we are up to around $2,000 to $3,000, give or 
take. That's still a bargain compared compared to what's available on 
the market.
