First I have a Mc Gregor R60 superhet sc receiver, I need info as to what crystals fit, ie: does it have the early unusual i.f. frequency or regular later standard?
Secondly, I have an unidentified superregen receiver 27mhz , As the relay is samped OS Japan , im asumeing its an early OS unit.
also anyone know what voltages these use?

Re: Receiver Identifications and info
Not sure about the first one Stewart but the Blue aluminium one is almost certainly 470khz IF frequency. 470khz below tx crystal.

Thanks Ron, I suspected the McGregor had a 470 if , you wouldn't know were I might obtain a set of crystals?

Hi Stewart,
Here is wiring diagram for my RS-1 superhet Rx which most likely has the same relay - max 6v/1A
Cheers,
Wayne
