To provide the interfaces, designs, etc. that are not public domain, to 
provide substitute software, etc.,  you are talking about spending for 
one receiver, about as much as a complete stand alone receiver, IMHO.

You might be able to strap some of the auto controls out of circuit and 
use the basic receiver block diagram as a simple receiver.  What I 
suspect is that the sub receiver probably used some front end filtering 
shared with the main receiver, and that is costly to recreate the tuned 
front end.

It may be that the receiver board was more independent, but my SWAG is 
it was just duplicating a detector, and perhaps an IF string.  Did it 
even have an independent audio out circuit?

You would have to study the block diagram and schematics well before 
embarking on such a project.  I would also speculate that the demand 
would be so intermittent or low that it would not be economical to kit 
up by a vendor.

Certainly, there is nothing in it for Ten Tec, who after all, are 
selling a complete transceiver with improved sub receiver.

But, if you go to the theory of operation of the model, you might answer 
these questions after some study.

I have seen many wonderful circuits supplanted by later model upgrades, 
and I have often wondered why you could not put the whole to work as an 
independent whatever.  invariably, upon close study, these wholesale 
removed circuits are nothing more than a compact storage of parts which 
you might reuse in something else completely different.  And, that is 
how they usually end up in our junkboxes.
