priller Posted October 24 Report Share Posted October 24 Morning all, can I get a sanity check on local freqs/tones/repeaters/nets? https://www.radioreference.com/db/browse/ctid/1946/ham Using this as reference point, for the GMRS freq at bottom of page. That's not a repeater right? That's just a freq+tone to use? Same question for the Amateur bands listed in that link? I need a GMRS Elmer to help me figure this all out haha. Have a good day folks.

Are you asking about that Charlotte 575? Yes, that’s a repeater. See how it has a frequency of 462.575 MHz. That’s where you receive it. Right next to that it says “Input Frequency 467.575 MHz”. That is the frequency that you must transmit to the repeater on. That’s how full duplex repeaters work, they receive on one frequency and simultaneously transmit on another. Receiving and transmitting simultaneously is called “full duplex.” There’s also simplex which means transmitting and receiving at different times on the same frequency. Your handheld radio, if it’s a designed to be a GMRS radio, has a group of repeater channels. Sometimes they’re numbered 23-30, sometimes they’re labeled rp15-rp22 or something like that. They automatically transmit on the repeater input frequency and receive on the repeater output frequency. Tones are used to limit access. They reduce interruptions from people on the same frequency but they don’t offer any security. WRUU653 and WRHS218 2 Quote Link to comment Share on other sites More sharing options...

Thanks Steve, I guess I was confusing myself between all of the listings on RadioReference, whether those are repeaters or just chat 'nets. I've been listening to plenty of ham chatter (I'm not licensed yet on amateur), but yet to make GMRS contacts. Having a lot of fun trying to figure it all out. Thanks again SteveShannon 1 Quote Link to comment Share on other sites More sharing options...
Socalgmrs Posted October 24 Report Share Posted October 24 What he said. It’s right there on the link you sent right next to the out out frequency. Unless I don’t understand the question. Quote Link to comment Share on other sites More sharing options...

Nets usually, not always, happen on repeaters. It’s usually a time to take roll call and test equipment. Chatting is chatting. Usually happens on repeaters and simplex.

I think I confused myself at first thinking it was just local simplex. I'm sure once I make first GMRS contact things will make a bit more sense. I'm trying to use https://mygmrs.com/repeater/4438 as it should cover my location. Should be simple enough to reach and use correct tone, but I haven't been able to confirm with contact or squelch tail yet. Will keep trying. I'm just a noob with HT, but having fun.

Thanks for the help Start by listening without a DPL code on the receive side. Understand that not all repeaters have a squelch tail and many will not have people listening at all times. By listening without a code or tone you’ll hear everything. Once you are sure you’re hearing the repeater work on transmitting to the repeater. You must have the right DPL code on your transmitter or the repeater will disregard your transmission. Once you know you are able to transmit to the repeater, then go back and add a tone or code to your receiver to limit what you receive to the repeater.

You're talking about the Charlotte 462.575 / 467.575? Yes sir, that's GMRS repeater pair alright. I didn't really notice what you were referring to, but that's a GMRS Repeater, not Amateur Radio 70cm. Quote Link to comment Share on other sites More sharing options...
