Hi Paul –

I thought that the 191/375 used the same tuning units. Only difference being the operating voltage of 12 or 24. 73 – Mike

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 and 

SCR 183/283 radios...and the BC 375 to a lesser extent but still a few.
