[WIham] Some radio questoins

[Jimmy c]

Hi,

well Im going to try and ask a couple questoins and give a update  in one post.
So here goes,

A while back I post I found a old pro 20 scanner, I found crystals cheap so if it dont work im not really out.

OK. One them old crystal radios, as I understand you need 2 crystals per chsnnel one to recieve and the other to transmit. How do you tell if a crystal is a recieve or transmit? 

Last questoin does anyboby know if you can get a programing cord or if you need one of them programing box things to program a RELM / Regency RSP500b VHF Handheld. I cant seem to find alot of info on this rig. 

thanks,
