[ARC5] Frequencies For Surplus Gear

[releazer at earthlink.net]

I have a PRC-25, two PRC-77 and an ARC-114, all in operating condition.  These sets can't get 52.525.  The closest they can get is 52.5.  Is there a good, accepted frequency used by such radios?

Yesterday I finally got the correct antenna for my ARC-116.  Is there is a generally accepted 220 MHZ frequency for AM radios in that band?

Thanks!
