Hello! Are you sure of the model number? I am very familiar with Microtel and have a bunch of their stuff, but never heard of a 1900 model. What was its range and how was it described (all in one/modular/etc.)?

I picked up a Micro-Tel Microwave Receiver
(Model 1900) the other day. It's still in transit,
but searching the Web for info on it comes
up empty.
 
Back when it was new, I expect it was not
advertised too widely, but I thought I would
find something, but no luck so far.
 
Any leads on where I may find more info on
this item ? A Service Manual would be ideal.
 
Tnx, Dick, W1KSZ
