Gerry,
I hadn't heard about the acquisition but it makes sense given that they seem to have been rapidly winding down service support for the shortwave receivers. The most recent Drake receiver I have is a R-8 (although I guess the Eton E1-XM has quite a bit of Drake DNA) but they seemed to be doing pretty well with specialized broadcast gear.
The R-7 and RR-3 are extremely similar and I used the R-7 service manual to troubleshoot my second non-functional RR-3. It has a problem on the digital control board which hopefully will be rectified by a replacement IC.
Dennis,
I would definitely say these two are all male
Some receivers have a feminine touch but these Drakes are all business like.
I imagine post-acquisition the remaining service parts will rapidly disappear.
