To talk to a friend, simplex (no repeater) and a tall antenna may work for them.

Generally you set your dual band mobile radio to access a 2m repeater and use the UHF side of the radio in a simplex fashion with an HT to cross band through your mobile to increase the range of your HT. In Texas the UHF areas set aside for this are 440.750 - 440.975 Cross Band Repeat - Fixed 445.750 - 445.975 Cross Band Repeat - Mobile Backyard repeaters are a different matter. These pairs are not assigned and available for anyone to use on a temporary basis for events like bicycle rides and marathons, etc. CTCSS tones are required VHF CH 1 - 145.250 out / 144.650 in UHF CH 1 - 441.300 out / 446.300 in UHF CH 2 - 441.325 out / 446.325 in UHF CH 3 - 441.350 out / 446.350 in UHF CH 4 - 441.375 out / 446.375 in I have a Motorla GR1225 setup as a portable repeater to use at events. The duplexer is tuned in between .325 and .350 which allows operation on all 4 frequencies without desense. We have had occasion where we start on one frequency and get interference and have to switch to one of the other 3 --jv On 6/8/2020 8:40 AM, SETX Telecom via BVARC wrote: Texas had, not sure if they are still there after the VHF FM Society has been changing things without membership voting on it, allocated several crossband pairs for such use. In any case, TSQ should be use to prevent lock up and interference. As well as lowest power needed...typical ham rigs cannot handle broadband at full power anyway and will tend to burn up the PA if used at high or even medium power levels in xband rptr mode On Mon, Jun 8, 2020, 8:22 AM Rob KC5RET via BVARC <bvarc@bvarc.org<mailto:bvarc@bvarc.org>> wrote: Hello all, Was reading one of my facebook groups today and there was a ham looking to setup a small low powered crossband repeater so he could communicate reliably with a friend, but he wasn't sure what to look for. I'm pretty sure he needs a set of "Non-coordinated crossband repeater pair frequencies." Where would someone look for such a thing? I performed a google search and didn't find a consensus. My guess was, even though it would be a non coordinated repeater, he would need to check with the repeater coordinator in his area, to find out what those frequencies would be. Thoughts? 73, Rob, KC5RET EM20KE ________________________________________________ Brazos Valley Amateur Radio Club BVARC mailing list BVARC@bvarc.org<mailto:BVARC@bvarc.org> http://mail.bvarc.org/mailman/listinfo/bvarc_bvarc.org ________________________________________________ Brazos Valley Amateur Radio Club BVARC mailing list BVARC@bvarc.org<mailto:BVARC@bvarc.org> http://mail.bvarc.org/mailman/listinfo/bvarc_bvarc.org
