Data Burst on MURS

jaymatt1978 · #1 (**permalink**) 07-08-2009, 9:55 AM

Over the last few days I've hear data bursts over MURS 1 (151.8200) has anyone else in Northern Bergen County heard the same thing?? Wish they would use a PL so I could lock it out!

You could be receiving a facsimile transmission on murs,which is a form of data.
That is allowed on that channel even though it's seldom used. If you had a camera and a sstv converter,you could transmit pictures as long as your not using more than 2 watts out!

I've heard the same thing on MURS in IL. Turned out to be Garmin Astro. -

It appears that sub audible selective squelch is not a product feature.

Garmin has stuff which transmits on murs channels? I knew they had a model which transmitted on frs/gmrs channels. So can you use the astro to talk on murs channels too?
Other murs users might be interested in this.

Yup, look at the Astro user's manual. It lists the MURS freqs. that it works on. I know a person who uses Astro and loves it.

Well that's cool,because other members here on RR have been looking for radios which are "type accepted" with all 5 murs channels pre-programmed.
Is that unit capable of pl tones on murs too?
I might want one for camping!

After a cursory look at the user manual, it did not mention sub audible tones.

Believe I read awhile ago that Garmin received an FCC waiver allowing thier GPS transmitting equipment to be FRS/GMRS/MURS type accepted.

IMO and from others, Garmin makes great GPS products. Wish I bought their stock IPO!

Great so it looks like I'll never find out WHERE it'sd coming fro]m. Although two watts isn't that hard to trace?!

Not without DFE or a directional antenna. If hearing the data burst bothers you, you could program your radios with a PL if they are PL capable.

It may also not be GPS that you're hearing too...

At this moment I'm hearing data bursts on all 5 MURS frequencies. Some sound a lot stronger than the other and it almost sounds like APRS data heard on 144.39.. I'm recording a sample for anyone who wants it. Also there is almost no break in between transmissions. Maybe half a second at most. So since I'm scanning all freqs in one bank with the delay feature off, it sounds almost like constant data.

Also, I may have read somewhere that it might have to do with GPS and Geo-caching for those of you who follow that.

Garmin Astro GPS unit uses MURS channels.

Probably nothing to do with geocaching. If it has anything to do with GPS it would be RTK or DGPS data. Is there any farming, oil/gas exploration or surveying in your area?
I could be something else totally different too.
