[Boatanchors] A design project?

I have an RME VHF-126 converter that covers 6 meter band, 2 meter band
and the 220Mc band. I also have an RME converter that covers 80 through
10 meters.
The VHF-126 converter has a huge tuning dial as well as a band switch
which indicates a fixed frequency output while the HF converter has only
a band switch which would indicate that it is only a converter and NOT a
tuner.
Now the first thing I need to know is just what frequencies these two
converters put out. BUT on BAMA there are no documents on either of
these rigs. Does anyone know of a source...realatively inexpensive, of
course......for such data. I would be happy just to know the output
freq for the VHF unit and the output band for the HF unit.
Where the design comes in is that it would seem that in the case of the
VHF unit it would be a very nice project to design a fixed frequency
receiver to run the converter/tuner into. Since it would only have to
be a single frequency receiver and not need to be frequency agile it
would seem that a very GOOD receiver with all sorts of bells and
whistles and AM/FM/SSB/ etc could be done relatively easily without a
lot of frequency agility to mess up the design. In the case of the HF
converter you still only have to deal with a 1mhz wide receiver so it
still gets rid of a lot of complexity.
Yes, I could get a wide band multiple freq receiver that covered the
frequencies I needed for the converter outputs, but that is over kill
AND since I could eliminate a bunch of front end crap it would seem that
maybe, rather than design something already designed, a very well
designed Military Surplus rig that was otherwise not of much use could
be utilized.
This is still in the brain storming stage so any comments of any sort
are welcome.
