[Milsurplus] Think I asked this before about an RCH

[Robert Downs]

I agree.  It could have been done by Scott but if so, USN doesn’t appear to have bought it.  When I was aboard USS Valley Forge (CV-45/CVS-45/LPH-8) in 1967/68 we had two or three RCH’s still aboard.  I couldn’t swear it about the others but the one in the Crew’s rec space across the passageway from the ET shack did not have such a modification.  And the (AFAIK only) RCH manual doesn’t have anything in it on such a mod.

Charlie,

I have 2 RCH and 2 SLRF, (1+2 are waiting for bench time to be recapped) and none of them has a reduction drive. 

I think it must have been a good homebrew modification if it looks like an official mod....

Since the subject of Scotts and their RX's, I have an RCH question I may have asked before, but perhaps a knowledgeable RCH fellow was not on the list then.  Was there ever a dial drive reduction mechanism provided for the RCH series?  The RCH dial is a  metal disk, and on mine is a  reduction drive that is switchable, in or out.  When in, a 2 part metal, spring loaded wheel engages the edge of the metal dial, and friction drive rotates it via the gear drive attached to it.  When out, it is disengaged to allow the main dial to tune it.  The in/out switch, and the vernier tuning knob are concentric to each other. The reduction mechanism is a manufactured device with a casting, not a kluge set up.  When the drive wheel engages the metal dial, it does it perfectly,  it has a detent mechanism that snaps it into position, again perfectly.  I have looked at a lot of RCH pics and that extra knob to the right of the main tune is on none of them.  The next question, which piece of mil
 itary gear, had a mechanism such as this that it could be installed on this RCH?  The knobs are gray, a bar knob to engage/disengage, and a metal knurled knob about 5/8's diameter for tune.  That installation is so good, was thinking it was an official modification, since on the other side of the receiver, somebody screwed up the audio selector and thought they needed to drill a hole and install a toggle switch, one modification excellent, one crap.
