[Amps] complicated Bias circuit

[Paul Decker]

Hi Paul,
Agreed!  But it's in my shack now, while I don't need qsk, I do need TX/RX capability.

you should see the inside of the power supply and the RF decks, absolutely gorgeous and stunning construction.  I had them at near-fest here this past week to sell and everyone commented at how well built they were.

At some point I'll post some pictures.

It looks like they're capable of supplying some well-constructed amps to the 
ISC markets.  Unless there's a specific requirement from a customer, they 
wouldn't ordinarily supply QSK circuitry, especially at the power level for 
their target market.  The facilities look nice too.  Would love to have 
access to their production equipment.
