DOT Frequencies

Post by mems47 »

Does anyone know the rules governing the use of these DOT frequencies (e.g. Red Dot, Green Dot, Blue Dot, etc...)? I was interesting in programming some of these frequencies in our squad radios with DPL's. However, I'm not sure if I can do that without an FCC license.

Thanks,

Sean :-?

Last I checked, I think there were about 7 "dot" frequencies. Most of them were converted to a licence free service, MURS. There is a 2-watt limit on all of them. Other dot frequencies do require a license. As long as you give a valid reason for using them, you should have no problem obtaining one. 151.625 MHz seems to be the most popular (at least around here). There are also others in the UHF band. What frequencies do you already use? Do a search on itinerant frequencies, or others here can add to this.

These are all the DOT frequencies:
Blue Dot 154.5700
Red Dot 151.6250
Green Dot 154.6000
Purple Dot 151.9550
Brown Dot 464.5000
Yellow Dot 464.5500
White Dot 462.5750
Black Dot 462.6250
Orange Dot 462.6750
J Dot 467.7625
K Dot 457.8125
Silver Star 467.8500
Red Star 467.9000
Gold Star 467.8750
Blue Star 467.9250


These USED to be DOT/Itinerant but are now MURS
151.820
151.880
151.940
154.570
154.600

All it takes to get a license for the current intinerant frequencies is a submission of payment. No coordination is needed.

The new MURS frequencies are "licensed by rule", meaning anyone can use them without a license. It is also acceptable to use PL/DPL on these frequencies, but I don't think a repeater is.

You must have a valid GMRS license for the following
White Dot 462.5750
Black Dot 462.6250
Orange Dot 462.6750
If it is for a business you will not get licenced on these.

What radios do you own?: Progreso soup can with CRT

DOT channels...

You guys always leave out 469.500 and 469.550 which you can also get just by asking for them. There are no color or dot designations for these two itinerant channels.

And also note that 154.600 was a dot channel and is now a MURS channel.

The FCC regs on what you can do with MURS as regards to splits, autopatches, etc. are extremely unclear. A cursory reading will tell you that a lot of things are possible using MURS because so many things are not forbidden.

Those frequencies are the other part of the repeater split for Brown and Yellow Dot.

No, they're not repeater inputs. I got a license for them about five years ago and they were/are itinerant simplex channels. Some listings show them as such and other lists, such as the lists above, don't show them. If you doubt this call the LAO and ask them.

Really? I always thought they were for mobile/repeater operation, considering they were 5mhz higher and in that band that's the offset. Hmm...learn something everyday.

"469.500 and 469.550 which you can also get just by asking for them. There are no color or dot designations for these two itinerant channels. "

These ARE itinerant Repeater input(s) are NOT to be used for simplex. These REQUIRE a license.

The MURS freqs are restrictred to 2.5 khz deviation and two watts max.

The 154.57 and 154.60 ARE still used by licensed stations, MURS is SECONDARY to any licensed station operation. They also are 5khz deviation and two watts max, no repeaters or base stations allowed.

Thanks for the confirmation Will, I thought it would be weird to have a simplex channel 5mhz higher in UHF. PM me with when you want to get together about that x9000.
