Looking for recommendations for a radio I can use to call and receive my position on logging rds. I don't know what type of radio is used (vhf uhf.?) Looking for an economical brand. I mean cheap btw not "buy quality once" economical. Other question is, do i need a license to call my position? I assume people would rather see me calling without the paperwork as opposed to not calling and being surprised to see me on the rd. Also would need to know how to find the channels being used on a given rd.

I know this has come up before but I'm not very proficient with the search feature here.
