MURS Mobile

Which if any mobile units can be programmed for narrow and 2 watts to use as a MURS mobile? The HT rolling around in the seat is getting old.

There is the RadioShack 19-1210 mobile/base radio, wich comes pre-programmed on 154.6/154.57, and theres a website out there that lets you know how you set it up to do just about any frequency in the 150.01 to about 157.0 frequency range, programming is done via DIP switches. I use mine to monitor my local FD, and talk on the MURS channels. It can only do PL, tho. No DPL, just the 'standard' 38 PL codes. It comes doing TX at .5 Watt, but it will do a max of 5 watts with proper tuning. I would not reccomend using a commercial rig, tho, because it wouldn't be type accepted for the MURS band. Sorry, no /\/\ radios out there for mobile use on the MURS. (at least that you can legally use) I hope all that made sense.

I guess I should have specified Motorola.

Maxtrac radios came in an LPI (Low-Power Industrial) version of 2 watts out. Their model number would likely start out with D04 for UHF, and D03 for VHF. Suggest digging around on the for-sale/wanted forum here, ham swaps, and greed-bay.

Happy hunting.

The low power Maxtracs would only be usable on Chan 4&5. These are allowed 20 khz band width while 1-3 are restricted to 11.25 khz. Of course you could turn the modulation down to 2.5 Khz on the transmitted signal but you would still have the wide open recieve filters in place.

As to the legality of commercial radios, the FCC field office in Houston told me that Part 90 radios are grandfathered. When I asked for something in writting I was sent this:

"(g) Each Multi-Use Radio Service transmitter (a transmitter that
operates or is intended to operate in the MURS) must be certificated in
accordance with Subpart J of Part 2 of this chapter, Provided however,
that those radio units certificated as of November 12, 2002 need not be
recertificated."

I asked about the HT1000 in particular and was told that as long as it was programmed to meet the bandwidth and power requirements it was legal.

I had a M03 VHF 2ch Maxtrac that was a 2w radio. I think there is a M04 UHF as well.

Look for them as well as the D models, they usually go cheap because of the low power tx.

I've seen the 2w Maxtracs on eBay alot going for around $80-ish, but I had no idea that they came factory wtih 2 watts out, I thought the reason they were cheap is because the radio was damaged somehow and the power dropped. Interesting thing about the HT1000 tho, I'll have to keep that in mind. Now does anybody know if MDC1200 signalling is legal on MURS?

Here is the FCC regulation link on MURS http://wireless.fcc.gov/services/person ... perations/. I have two of the Radio Shack mobiles but here in my area the MURS is quiet. I only hear drive thru's.
Good Day, Radio Kid

I think the reason MURS is so noisy around here is that the local rat shack and wal mart were selling a ton of cheap HT's of various brands for a while. The things were flying off the shelf, probably because there is a need for personal coms around here, but everyone despises the local Moto dealer, mainly because of his huge markup in sales prices.

I hear everything from farmers, to mom and dad hollering at the kids, to commercial users that originally licensed for one of the now allocated MURS channels.

All of our local drive throughs are using UHF. Hardee's has multiple channels to move around, along with PL encode/decode on the headset and drive through order units.

Mcdonalds and the others are also on similar 460-470Mhz frequencies.

We have basically the same situation around here, but no farmers. It seems as tho the PL everybody seems to be on is 67.0Hz (or the number '1' on the display for PL tone) The reason this is, is because all Motorola XTN series VHF radios come pre-packeged on what I believe is 154.6, with a PL on 67.0Hz. When the company charges them up and uses them, they (the radios) talk to eachother so they have no need to change the settings, thus ALOT of the MURS users are 154.6 P/L 67.0 Just tought I'd advise not to use that PL.

What about M1225 VHF?

Lowest it can go is any Tech's guess, but I'd say 10 watts?

Hello.

I would use a good quality /\/\ talkie and a CVC.
This would be the best of both, and the talkie can easily be set for 2 watts.
All the newer talkies can do both narrow band and wideband on a per channel basis.
You can sometimes find a good talkie with CVC for under $100 with a bad battery.

Played with a D43 Maxtrac last night and the power will go down to 0 and is stable at 2. I 'spose on could crank the deviation down and change the recieve filters. For now I will program a 2 chanel up on MURS 4&5. I was wanting to avoid 154.600. Primary will be 154.570 on a 20k channel for now.

And I'll watch fleabay for some convertacoms for the HT1000s
