222 is hard to find in many areas. One problem was when the lower part of the spectrum was taken away for a commercial use which was never developed. The use of VHF/UHF FM repeaters has also suffered with the popularity of DMR. Many DMR repeaters were previously 440 FM, and hot spots have added to the DMR craze.
222 MHz band radios and usage
- Thread starter jaspence
- Start date
220-222 MHz was reallocated in the U.S. to be used by UPS for a data/voice system that their delivery trucks would use. It never panned out. 220-222 MHz is now used by the railroads for the Positive Train Control system that's supposed to reduce the incidence of trains running into each other.
222-225 MHz is now a primary amateur radio allocation in the U.S. Problem is that it's not an amateur radio allocation outside of ITU Region 2 (AFAIK), so the Japanese have traditionally had little interest in developing radios for the band. The Chinese realized that they could add 222 MHz band coverage to some of their radios, though, in my experience, the transmitted signal quality is sometimes pretty poor.

along those lines. i had someone ask me one time what radios run in the 220 range that have dmr mode like the power companies use in that area
Amateur radio in the U.S. is the primary allocation in the 222-225 MHz band. I'm not aware of any power companies in the U.S. using DMR or any other mode in that segment.

If I recall correctly, Kenwood once had a 220-only mobile rig in their lineup.
Rather than retype the list of radios from the past, go to rigpix.com, look for your brand of interest and search for 220, 222, 1.25, or 1.35 in the Band/QRG column.
As for current production, neither Alinco, Icom, Kenwood, nor Yaesu have any 222 MHz radios in their product line.

The Alinco DR235T was discontinued only last year and was the last of the 220 only rigs!
Last of the Japanese brand 220 radios, although it's quite likely that it was built in a Chinese factory like some of Alinco's other radios.
The Anytone AT-588 and TYT TH-9000D appear to be the same radio with a different face plate.

There is also a local to me here in northern Virginia (I tracked them down as they are not in FCC as it is leased spectrum):
Tait III DMR (2 TDM channels on each frequency), Color code 0. Callsign is WRBV929
for 217.000-217.500 frequencies and WRMM943 for 217.500-218. Some frequencies
are used by more than site. Input frequencies for the repeaters are 2 MHz higher.

Yep...but 220 seems to be an afterthought, add on as its only 5 watts out! With the lack of 220 repeaters you better have a heckuva an antenna!!!IF you can trust Bridgecom they show a triband mobile DMR radio that includes 220.

Following Yaesu's lead? Yaesu put out a hand held radio that made 5 watts on 2m/70cm and a whopping 300 MILIwatts on 220. VX-7 If memory serves.

I had a Yaesu VX-6R. They put out about 1.5 or 2 W on 220 and 4 or 5 on the other bands.
Tait makes some 174-225 MHz digital radios. I don't know about availability in the US.

I never had a problem with mine except for the batteries going bad and replacements were too expensive so I sold it.
Kenwood TH-D74A is a Triband handheld doing 2m, 1.25m, and 70cm all at 5 watts
I have two Bridgecom 220 mobiles and one HT. They have discontinued them although they still sell their 220 repeater. I ordered the second mobile because I knew they would be unavailable soon. The Bridgecom radios, at least the latest ones, were made in Korea. Now I think there are mainly Chinese products left. The Yaesu VX6R does do 220 at low power and is still available. Otherwise you will have only Chinese radios to choose from.
We have five 220 repeaters in this area that are not used except that one of them is linked to a 2 meter machine. Really a shame.

TYT TH-350. 5/4 watts on all three bands. Yeah I know, a CCR. But they run about $70, versus the Kenwood that was more like $600, and is now discontinued. The previously-mentioned Yaesu VX-6R is $250 (and only 1.5 watts on 220). I'm sure the Yaesu and Kenwood are better radios, but are they 3.5x or 8x better?
The latest Anytone DMR mobile (AT-D578UVIII-Plus) and the Alinco DR-MD520T (which I'm pretty sure is the same radio with a different front panel) also have 220 but only 5 watts.
