[ARC5] Looks Very Interesting

[Jay Coward]

Your right. I forgot there's no LO in the ARR-1. And your idea would then work.

There is no local oscillator for first down conversion in the ARR-1 or the ARR-2.  The YG UHF signal is modulated by a broadcast band frequency.  What looks like the first down converter in the ARR-1 and the ARR-2 is actually a demodulator whose output is the broadcast band frequency.  Hence there is no need for two motors.  It looks to me like the combination of ARR-1 + R-24 + Yardley whould function exactly like the motorized ARR-2.  Mike, W6MAB

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?

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?
