[ARC5] Looks Very Interesting

Remember, the ARR-1 is the tunable VHF front end and first down conversion to MF. The R-24 is the second down conversion and  IF and detector. Since the ARR-1 has a fixed LO, it has a variable frequency IF out. Thus a tunable second conversion down converter / IF in the R-24. To "autotune" this arraignment  you would have to have two motors but have different tuning characteristics for each and synchronize them.
 That's why they developed the ARR-2 and its eventual "autotune" version. And again, the Yardley mechanism is larger than the ARR-1.

I have two ARR-2s, one with, and one without, the motor.  We're not talking ARR-2 here.  If the Yardlley Spot Tuner fits on an R-26, it seems to me it should also fit on an R-24.  I think the ARR-1 or ZB-3 output should be tunable by the R-24.  Or is it just a coincidence that both the the YG system and the Yardley have six channels numbered 1 thru 6?  Mike, W6MAB

It would not fit. The later ARR-2 had some models with a motor to change   channels rather than a spline cable.

Couldn't this Yardley gizmo be used on a Broadcast Band ARC-5 with an   AN/ARR-1 connected to tune to the six channels of the YG Homing system?

The original two pole     six position switch assembly, true...you had to 
provide some sort of     enclosure for it, it had no markings on it other 
than channel numbers,     and that's not a good strategy for large scale 
installation...      However, as I mentioned earlier this morning, there is 
a C-188/ART-13,     C-189/ART-13, and C-284/AR shown at 
http://aafradio.org/flightdeck/box.htm - and the serial     numbers for 
these number in the hundreds.  You can recognize the     first two control 
boxes as designed for the Yardney because they have     "Preset Receiver" 
channels from 1 to 6 shown on the front panel.      The C-284 could 
reportedly be used with both the Yardney *or* the     ARR-15, and they 
dropped the channel number limitation reminder on the     front 
panel...guess you were supposed to know by now that the Yardney     had only 
six channels.

That'll work too. :-)

I have one of those as     well...:'(
