I am confused why in the write up on the SCR 506 that Ray quoted that it said :

"but takes the patience of Job to sort out the millions of tuning units"

What tuning units....the SCR 506 didn't use any tuning units.

The BC 191 in the SCR 193 that it replaced used a few tuning units

The radios IMO opinion that used a lot of tuning units were the GF/RU andĀ 
SCR 183/283 radios...and the BC 375 to a lesser extent but still a few.

It's also one of the most "fun" receivers to operate. Used one at the USS Ling in NJ for 11 years. Just a great receiver and built like a battleship. Sure wish I had one now!

Yes, Ray, I always found the comment on the RAL to be particularly amusing: being a very "economically challenged" young ham, I used an NIB RAL-7 as my main station receiver for around 12 years for every mode, and found it to be a superb receiver. I still consider it to be the finest HF TRF receiver ever built.

My ONLY complaint with it was the non-existent frequency read-out.

I also had an RAK. I used it to copy the VLF Navy stations for code practice. One thing I was surprised about was that the RAK provided "single signal" selectivity: the "other side" of "zero-beat" simply wasn't there. I still don't know how RCA accomplished that.

Many may regard the authors comments as derogatory but I find them entertaining.
Especiallly like the comment on page 71 of the manual with regard to the RAL.
