I don't get it at all - it doesn't run much power, so unless it's perched on the top of a mountain or hanging from a balloon - does it do very much? The frequencies are so close that desense means big and heavy cavities, or aerial spaced a very long way apart - have I totally missed the point? Probably, knowing me!

Interesting. They're also using 446.9875mhz as the repeater's RX channel so you'll need a huge antenna and your transmissions might go all the way around the world because it's such a low frequency. Don't know why they didn't choose a frequency in the UHF band or maybe on the VHF band would have been better then they could have had a crossband repeater.

Indeed, but they quote mhz, milli-hertz! With a small 'h' at that!

More power to your elbow mate, but I think you guys will be making yourself a sitting duck if someone get's the hump.

I notice their FB page says 446.9875 is an old SRBR channel......it isnt !

hope they're not near the coast as its rather close to a navy POLYCON frequency!

What are the chances of a 0.89375MHz split working with out cavities, or a big separation between antennas on Baofeng Radios?
