There are a few TMC DDRR-10 2-30 Mhz dual diversity receivers out there but
not many.  Picture and specs at
http://www.geocities.com/vintagetmc/ddr10-1.html

I have had one in storage since 1993 after moving from Atlanta to Dallas and
no longer having a place to put it.  It's the downside of no basements in
this part of the world and a hamshack on the 2nd floor.  It was in working
condition prior to that time, with a few things that needed attention, but
basically working (for example, the synthesizer output stage transistor
needs to be replaced, and the low order digit in the frequency display of
one RF deck needs repair).  I cannot guarantee its current operating
condition, and it is being made available AS-IS only.  It is still
physically ok, and actually very nice looking.  I've lost the screws that
mount the rear cabinet door, but have the door.  It's complete with 2
complete manual sets, all extender cards, some original spares, and even the
original drop-light in the cabinet.  

This is solid state (70's vintage), but one would have to admit it's
something of a boatanchor :)

The particular version of the receiver I have is a Navy AN/URR-64(V).  It
has two receivers (2 RF decks, 2 IF/audio decks) and one synthesiser deck
which can be used to feed none, one, or both receivers.  By contrast, the
FRR-85(V) pictured in the link above has 2 synthesizer units.

I will have some pictures of the rack and modules the week before Ham-Com in
Dallas (Plano) and the radio will be available FOR PICKUP ONLY near DFW
after Ham-Com (very late Saturday 6/9 or after).  It consists of a 6' rack
and 5 modules.  Large and very heavy.

If anyone has a serious interest let me know and I'll send photos when
they're available the week of June 4.  This receiver does not have a belt
clip :)
