[Milsurplus] Xtal for ARC-1

[telegrapher at att.net]

I'd like to find a crystal for my R-28 and ARC-1 receivers for 144.450
Mc which is the local 2 meter AM channel.  May never hear them way out
here in the boonies but one never knows in this game.  

I think the one for the ARC-1 is 7485 Kc.  Dunnow what it would be for
the R-28 VHF receiver.

The ARC-1 unit is a CR-1B/AR holder.  Is it the same for the R-28 VHF
command receiver?
