Just to share my latest project on testing stage, GM300 repeater putting out 20 watts on dual antenna setup. https://hosting.photobucket.com/images/d49/alincastre1223/RPT_3.jpeg

Nice!! Motorolian motherships... G.

GMRS would probably do what you want - and might be a really good fit, especially if you want to use hand held portables. GMRS runs on UHF frequencies - and you would not re-use your old VHF antenna(s) for GMRS. If you're more interested in just having mounted radios in your vehicles, then VHF might still be a good option. Pricing for VHF vs UHF/GMRS radios would be comparable. The cost of a Repeater for UHF/GMRS would probably double the overall cost of your system. I think that you should probably try to get some local help - someone who knows radios and could take a look at what you've got, and ask the right questions about what you want to accomplish, and give you some ideas of what might fit your budget. Someone else will probably bring it up - but GMRS licenses run "per family" - ie: One license covers one set of relatives. If it's a family farm, it's pretty simple. If you've got unrelated employees, then potentially you would need to license each of them individually. A VHF or UHF commercial/business License would not have those limitations, but it is more expensive to set up a License for that type of operation with the FCC. I've got a nephew with a family farm out in Indiana. He's running GMRS with a repeater up in the barn, and he gets a good 3-5 miles with portables - even further with his mobiles.

I'm In, thanks!

Thanks to everyone who responded to my inquiry, very good info here. I've just returned from taking the duplexer to a professional radio shop for tuning to 462.550. The Fumie duplexer still has a 20 watt lose on TX. It appear the Fumie is junk and the advise of the radio technician is to stay away from the cheap China duplexers.....all of them. His minimal recommendation was a ICOM at a cost of $395. I think I'm going to investigate using two antennas instead of a duplexer. As long as I have signal separation to prevent bleed-over it will be less expensive and provide full TX power from the repeater. We are moving forward to the next stage of our project. Thanks again for your support! Mike WRJE502

This is absolutely incorrect! No amateur radio service license allows operations on GMRS frequencies. Power level is limited per FCC GMRS rules, not a ham license.

HT antenna - hell NO! Totally misguided. Mobile antenna on the roof your car or maybe base antenna on the top of your house - yes, techniques involving SWR meter and/or power meter might make sense. Beware of people who do not know what they are talking about. Nowadays anyone can start a youtube channel filled with anything. "Do your research!" Lol! Also consider that good SWR does not mean a good, efficient antenna. Dummy load (from a reputable manufacturer) has a perfect SWR.

I think the treaty with Mexico for coordinated land-mobile UHF comms is for 470-512 MHz; link to current treaty dating to the mid-1990s from the FCC page is given below. https://transition.fcc.gov/ib/sand/agree/files/mex-nb/470-512.pdf The treaty region extends 150 km on either side of the border. The GMRS repeater pairs are 462 MHz outputs and 467 MHz inputs, below the 470-512 MHz range of the current treaty, so you're probably right a treaty modification would be needed for coordinated cross-border USA<->Mexico GMRS operation. Taking another look though Part 95 radio services, though the FCC removed the 250 km contact limit for 27 MHz CB, the only country listed with permissible cross-border contacts at 27 MHz is Canada's CB service (General Radio Service). https://www.ic.gc.ca/eic/site/smt-gst.nsf/vwapj/ric18-issue4-oct08.pdf/$FILE/ric18-issue4-oct08.pdf The clincher seems to be Part 95.1733(a)(9) which prohibits foreign (non-US) contacts for GMRS: § 95.1733 Prohibited GMRS uses.(a) In addition to the prohibited uses outlined in § 95.333 of this chapter, GMRS stations must not communicate: (9) Messages (except emergency messages) to any station in the Amateur Radio Service, to any unauthorized station, or to any foreign station; Anyway, good to know. I live in the southwest (New Mexico), so I guess we can't reply to Mexican operators that pop up on the Southwest linked system until some entity works the cross-border treaty issue.

gman's comment only applies if you are in a high-RF environment. Say you lived next to a tower that had a lot of other communications gear loaded up on it, particularly operating in the 450-470 MHz UHF band, such as a lot of police, fire, ambulance, taxi cabs, business band radios, etc... - When one of those repeaters is transmitting, say for instance at 462.950 (a medical paging channel) your radio tuned to 462.600 (GMRS 17) would be overloaded by the nearby strong signal, so it wouldn't hear anything on your desired frequency. Putting a high-gain antenna on a radio with this easy overload-state only makes it overload worse. This is VERY common in CCRs, which typically have no front-end filtering of any kind, and thus no selectivity. It doesn't have to be just a repeater interfering with a CCR either. My Baofeng's get overloaded when the police are using the radios in their cars 2 blocks away. Also, if you have a local TV station on UHF channels 14-21, you can just about forget using a Baofeng radio within 5-10 miles of its tower.

Very good point for us newbies! I have found repeaters not listed here, but local in the area. I figured that the repeater owner would not hear me trying to locate the CTCSS until I had found the correct code to get tone or, no static. I am on the very outer edges of two repeaters AND ONLY HAVE LIMITED time in areas that I can make contact in the mobile situation I am in. But I have found one owner that now listens for me every Weds morning as I pass thru an active area where we can chat. Hes happy his equipment is reaching the far and I'm a happy to know my rig is actually working as designed too.
