The following are downloadable files for codeplug programming and firmware updating for the AnyTone AT-D868UV and AT-D878UV handhelds and the TYT MD-380/390 handheld radios. few great FaceBook groups and Youtube videos to help you get your head around this.
ZUMspot Raspberry Pi Info and Setupĭave, AI6VX published an excellent tutorial for setting up ZUMspot hotspots. We sell ANYTONE AT-D868UV DMR HAND HELD at Radioworld UK for all your. Specifically 431.0125 MHz, 431.025 MHz and 431.0375 MHz are three good hotspot simplex channels that conform with the local SoCal 70cm bandplan. If you have neighbors close by who are using these frequencies already or you are on a promontory, you might consider using higher frequencies between 431.0375 and 431.600 MHz in 0.0125 MHz (12.5 KHz) increments. As there are NO suitable hotspot frequencies in the 435-450 MHz band segment, we suggest starting at the lower edge of the 431.00-431.60 MHz segment. The important consideration here is not as much the 10 mW hotspot devices themselves but the 5W handheld transceivers and the 25W-50W mobile DMR units transmitting on the hotspot frequency. When picking a simplex frequency to operate a hotspot on it is important to maintain good operating practice. I suspect these all work with the 878 as well.
On our nets we discuss various commercially made and homebrew hotspot hardware. I've come up with some cool settings for my D868 that I thought I'd share. SBARC DMR Talkgroup: 31073 Hotspot Frequencies (OpenSpot, Zumspot, etc.)Ī “hotspot” is merely a 10 mW transceiver used to connect to the DMR network when a repeater is either out of range or a user desires additional flexibility.
