[DSP-10] 8 Watt Amp.

[Perry Ogletree]

The DSP-10 is a 2 meter high performance DSP based SSB/CW transceiver.
The "brick" originally used with the DSP-10 had a companion PC board and 
support circuitry.  Huston is looking for that PC board.  The module that 
board used, however, is no longer made.  The FET module(s) I mentioned were 
class "AB" modules and would produce 15 or 30 watts output with 15 miliwatts 
of drive depending on module.  RF Parts did stock them at one time but I 
have not researched it for several years.  The bias circuit for the FET 
modules was much simpler than the original bipolar module and there were 
example PC boards and circuits on the module makers Web site.
