Motorola on a quarter signal

[whynot]

Found this in a tot lot on Saturday... Contacted the city parks division, but not theirs... Still trying to contact the mulch company, but no other leads... The battery is still charged, but the channels are used by a lot of businesses, so I'm having trouble finding the owners...

Motorola RDU2020, tape label on the front says "18" so must be a fairly large set of these somewhere... Looks like they sell for around $200.00, but without a charger, might be hard to get rid of it...

Try lost and found on craigslist

Was it on a particular channel? Turn it on and see what company is using it. Nice find though!

Good idea, dawg... No hits in craigslist lost+found... Thanks for the suggestion!

Kieth-Tx - The radio has two channels and a scanner function... Lots of chatter from a lot of different companies... Auto parts dealers, lawn folks, etc... I may try the nearby school adjacent to the park...

If you know someone who has a frequency counter you can find out the transmit frequencies and then search the internet for scanner frequencies in your city/town and it should give you the names of the companies that use that frequency.

It may be setup to work through a repeater of some sort. I.E. The transmit and receive frequency may be different by about 600khz.

You may also try to find a local communications / commercial radio dealer and they may be able to tell you who it belongs to.

Cool find. I agree, listen in to see who using it, and if you can communicate on it, talk to them.

A company operating a radio system like that is supposed to have a license from the FCC. I used to have to maintain the paperwork for such a system.

Find a local commercial radio technician company that would sell and repair these things. Usually a Motorola dealer will have exclusive territory. There may be some markings on it that they could use to identify the owner. Possibly the serial number of the unit would be recorded in their license information, but I don't remember if that detail is there. If there isn't a Motorola dealer in the area go to any shop that repairs communication equipment and they may be able to tell you where the Motorola guy is.

They may be able to identify the owner from the serial number, especially if they sold the unit to the owner.

Thanks everyone for all the suggestions...
I tracked the S/N down from Motorola to Grainger. They don't keep serial # records, so dead end there...
Also, checked on www.radioreference.com for frequency range in this area... Literally hundreds of companies using frequencies in this range in Orlando, so this might end up being a candidate for flea-bay...
