cheap GPS receivers	Reply

I have a source on cheap GPS receivers for $25 or less based on how many you order. They are the Globalsat BR 305 with the SiRF star II chip set, has built in antenna and its total size is about 2.5 inches square. It has a 6ft cabel with a RJ11 connector (phone cable connector) and its output is RS232 NMEA data. If any one is interested email me at mrgrimes1@yahoo.com

AD or not, these "hockey puck" gps heads are great!! They are superior in every way to the typical Tripmate, which I have 2 of already, and which cost me about $50 each, and took an hour or more each to modify for use with my APRS setups. These Globalsat units draw very low current (~80 mA @ 5VDC) and activate themselves when powered on, unlike the tripmates and some others. They come with an RJ11 telephone-style plug on them, which I promptly cut off and replaced with a DB9 connector. Mine runs easily on: - New Dell laptop with USB-only ports, using a USB-to-serial adapter cable with a pigtail routing 5VDC from the USB cable to the DB9 connector on unused pin #7 - 1 watt xtal controlled board controlled by a Byonics Tiny TrakIII. I added a pigtail to the Tiny Trakker to "rob" 5VDC from the 5V regulator already present. It operates the GPS with no increased heat nor voltage drop on the 5V output. These heads are very small and unobtrusive and I really am tickled with mine. I wish I'd found them first and saved the money and time spent on my first 2 Tripmates. The tripmate can take almost 10 minutes to lock from a cold power-up, and these Globalsat units take less than ONE minute, and are extremely sensitive compared to Tripmates. I have no connection with the vendor except that of a very happy buyer.... Jim W5AOX See mine in action: http://www.findu.com/cgi-bin/find-us.cgi?call=kd5spn-9

You can respond to the MRGRIMES email link in the previous message, or send a query to: DGarrett@Airbiquity.com (MRGRIMES and DGarrett charge the same, and could be the same person) Tell Darrin how many units you want and ask for a shipping price. Quantities from one to six are $25 each, as I recall, but the shipping remains close to the same whether you order 1 unit up to 6 or so. Darrin accepts PayPal and perhaps other methods of payment. Your unit(s) will normally arrive within a week or so unless you pay for overnight shipping. OR, you can buy them from ME, with the connectors of your choice already wired and attached and ready to plug in, at $50 per unit, plus shipping dependent on your address. You'd need to specify what kind of connector you want (USB or DB9 for the data connector, and what kind of connector for the power input... if USB, the unit is powered from that connector). My preference is Powerpole connector for the 12V DC power and DB9 female for the data/GPS output.
