Our club has a R-105A/ARR-15 that we will be selling on e*#*@) soon.

It is an amazing receiver, however, looking at its design I am wondering why they did not have sufficient leap in logic to make it dual conversion rather than a

single conversion with a rather broad band TRF IF.

  The local oscillator is not band switched and is multiplied for higher frequencies, a very good idea.

So close to a very amazing design, but still amazing enough.
