Call me slow, but I just maybe thought of something.

Chatting with someone in LA on 420.675 Cactus Intertie....

For kicks and giggles, checked the Salt Lake County Utah - Amateur Radio Link here in RR


I scroll down to:

449.00000

I have never noticed that before.


Anyways... would this explain why I hear Sooo many Keyups/Repeater Kerchunking on 449.0000 ??

Yeah there are alot of repeaters linked up, we "had" a couple down here eastern/south eastern Utah linked up too , on cedar mountain emery.. I got to check if its still operating

 

[enosjones]

I think there are some on Navajo mountain too near lake Powell into Arizona and into Nevada as well

Cactus has a nice presence in AZ. 449.000 is also used in AZ & is tuned perfectly - covers huge area! $125 a year for access into a great system.

Snow Pk links to Chuck & into Phx

North Kingman, Havasu, Williams, Flag & into New Mexico.

South Telegraph to Lemmon to Jack's in NM.

Aren't the frequencies below 440 MHz usually used for links? Here in SoCal, most of the traffic I hear on 420-440 MHz is repeater linking with occasional ATV and clueless CCR unlicensed users.

California coordinators are moving to increase the availability of repeater frequency. So far specific to 420-430. The 440 DMR repeaters slowly move to lower frequencies. Narrow banding 440mhz give more space. I'd suspect California is or has looked @ that option increase space even more?

Hotspots, some people use lower or upper part of 430mhz for personal low power Hotspots. I run a few Hotspots which 3 simplex & 2 are duplex. I've had to utilize 420mhz with a 3mhz offset that works well for duplex which is used to monitor - about 4 statics on each slot.

That's news to me. The SoCal UHF spectrum manager ( SCRRBA ) seems to be very tight lipped about things. Some years ago they changed the frequency spacing from 25 kHz to 20 kHz to add more channels. I know many hotspot users will pick 420/430 MHz frequencies for their link since it's relatively low power. The problem with that would seem to be while the hotspot is very low power, users forget to reduce the power of their handheld radio.
