Yes: repeaters use an “offset” to receive on one frequency and then retransmit the signal on their main output frequency. For GMRS, that offset is 5 MHz and the DB20-G is preset for that offset on channels 23-30. So when you transmit on Channel 15 it both transmits and receives on 462.550. Whereas on Channel 23, it also receives on 462.550 but transmits on 467.550. The tone is used by the repeater to determine if your signal should be retransmitted by the repeater on the offset frequency or not.

This should get the job done. This is an extract from the csv version, but it gives you an idea of what you need

Sure, if I want to eliminate one of the main repeaters in the area. I run 2 different scans on my KG1000. Police, EMS and fire on one side and My repeater, Holyoke, Enfield and Glastonbury. Glastonbury is the one that has the DMR break through. But I have DMR interference on all frequencies 1-22. Seems to be pervasive in my area. The emergency frequencies rarely have any interference.

No strawman to it. It might NOT have been what you were referring to, but I can promise you that even today with statewide 700/800 radio systems the ARES guys STILL 100% believe that they should have access to that system and every analog public safety repeater on the air. And it's not just the ARES crowd. The number of average hams that 100% believe that little blurb in part 97 about 'any means at your disposal' means talking to the Po Po is completely acceptable and expected. I had this discussion with a couple hams about 10 years ago. They were adamant that was what it meant. I had to talk to the FCC on business related stuff and ask them as a side question about it and that is exactly what they said. Ham operators can use any HAM frequency in the ham allocation during an emergency. But that was it. They went further to state that modifying a Part 97 (ham) radio was against the rules and at no time should a part 97 radio be used on part 90 frequencies. They also said that even if they were using commercial part 90 radios, that without prior authorization being issued that they would be in violation. They emailed me all of this and I actually printed it out and had it laminated and would stuff it in the face of the hams that were convinced they were authorized by the regulation to talk to the public safety dispatchers on their channels, from their personal radios, if there was an emergency. I run into this about once a month. Someone will bring a radio into the shop they want loaded with public safety frequencies they got from radio reference. Half of the stuff isn't even on the air any more. Hell, some of it I pulled from service. We just tell them that they need letters from the fire chief / sheriff / someone on letterhead with an MOU and we will be happy to program them in. Without the MOU in hand they get nothing.

You need one of these. You won’t regret spending the money. https://www.amazon.com/Upgraded-TinySA-Spectrum-Frequency-Generator/dp/B0BBGK9QJB/ref=sr_1_1_sspa?dib=eyJ2IjoiMSJ9.E2AAv7H7z2PGLOgyJTAO-jFyX5El88briZR7abomJlt6lrN42NjxPUaKIc37w3hBUbBh_ZQs88keonNdxBj2tmSDY6qZPoT1yzD3N4i7oAF8JqLLJ919K2ka6MUwIHRhhGxf84NA519KaW2ymkv3Druf5x1ODuooPRLZZR5r_0JEAVykbfeMWCoo677OWPN_8XDeycpVtmpwi8N9lcPYAAo08cF4Luy0fvCTRpaYnME.uF1TvflqM_sedTmU2VZSBh_uHbIBjR5HKXL5-YeS_hY&dib_tag=se&hvadid=694399657356&hvdev=t&hvexpln=67&hvlocphy=9031792&hvnetw=g&hvocijid=8588421908655988712--&hvqmt=e&hvrand=8588421908655988712&hvtargid=kwd-950925853801&hydadcr=13153_13399500&keywords=tiny+spectrum+analyzer&mcid=273461ec36b53e08a9a40d42412c327f&qid=1753502082&sr=8-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&psc=1

The Garmin Rino screen actually gets brighter and easier to see in bright direct sunshine.

Got one coming. Saw that when ordering a UV28. I like the group option which both radios will do.

The only HT I own with good screen resolution during the day is my Hytera 682. My GM15 Pro is not bad when tilted to shade.

Can’t you eliminate that channel from scanning?

It really helps to know which port to choose if you’re watching the ports in Device Manager when you plug in the cable. You’ll see which virtual port is created by the driver.

New here as well. Did you make it work?

thx

No.

Hey there - im also having harad time - 1. Can you help with chirp settings? I think i got it right its TOne squelch 141.3 (WRQD476) and Duplex is +. 2. How to test repeater outside of hello callsign message. I am in its range but how to test f it goes through and noone is talkin? use 2 radios and try out of LOS communication around it?

Just wait until you see the new DM32 ....

I have to look away so I'm not buying a new radio every 6 months.

I have had to go thru as many as 5 virtual ports in software to find a compatible port for some software. The ports aren't the physical plug in ports on your machine, they are the virtual ports in the software. As the Grand Master points out, different drivers can have their own preference for one port over another - and Windows sucks.

Mine happen at any time during the day and night. Usually more during the day. Seems to wane at night and weekends so I think it's more business related than anything else. It makes it very hard to use my scan function because it gets stuck on the noise even when it's squelched.

No kidding, though, I really like it. It has everything I like about the 5RM with a couple of extra features. The screen is still impossible to read in bright sunlight, though.

Well, there ya go! Spend your 30 bucks and get it all. You're welcome.

Goddamn it, it sure as hell does. A quick look at the amazon link made it look like it was broadcast AM/FM radio, not VHF AM / FM.

Its been a struggle, but we will get through this difficult time.

I think it does. I'm not sure because I'm not interested in listening to air bands. Edited to add: It's advertised as receiving AM 108-136 MHz. Does that cover the air band?

dang, if that had air band receive it'd do basically everything I wanted

It was the bank scanning that decided me. I really like the 5RM. The lack of banks was one of my few complaints about it. The 5RM is still useful for most of my purposes, and will get plenty of use, but there are occasions when the bank scanning will be nice to have.
