Hi The Furuno receiver on the board is an older model. It’s similar to the M12’s. Not quite as sensitive as the “modern” stuff, but still very usable. Tough to beat the price … hint: the guy takes offers … hint hint Bob > On May 1, 2017, at 5:35 PM, Gregory Beat <w9gb@icloud.com> wrote: > > Interesting surplus GPS receiver / 10 MHz item on eBay > http://www.ebay.com/itm/GPS-Receiver-board-from-TruePosition-GPS-locator/152340314423? > TruePosition GPS Receiver/10 MHz oscillator, auction number: 152340314423 > > Supposedly, this receiver is extracted from Time Position LMU300 model 101333. > Rack unit used at cellular sites, the LMU Universal system assisted to determine mobile phone location: emergency, 911 systems, etc. > Lots of parts :-) > http://www.ebay.com/itm/TruePosition-LMU300-GPS-Navigation-model-101333-/162267042516?hash=item25c7de92d4:g:wEgAAOSwAvJW~UIi > > The Mt.

I've got one of each on the way to me. I've got an e-mail into the authors of the Packrat GPS Receiver Project slides asking about getting my hands on the Arduino code and asking if they happened to have a copy of the full programming reference. :) I'll share what I learn with the group. :) thanks much and 73, ben, kd5byb
