Hello FRG-7 users, i have one heading my way and on the rear there is a port simply labeled "counter".....According to the prior owner, he said "?
Gilfer Shortwave and Electronic Equipment Bank were big shortwave radio stores back in the day and they did mods to Frog 7s to take a digital counter." The thing is I cant find much information out there on what kind of digital counter it could take and if its something others here have seen.
Thanks,
Lou
