<pre wrap=""> Been away from APRS mobile for a while. What is a good GPS
receiver to use with the D700 mobile? I see lots of GPS modules now
for drones as well as micro controllers. In the old days used a garmin
OEM unit.
Al, k9si

devices with great success. This is the SERIAL version of the

<p><span id="productTitle" class="a-size-large">These devices come
with a mini-DIN connector on the end of a 6-foot cable that was
intended to mate with one of two accessory cables. One was just
wire terminated in a DB9 serial plug. The other terminated in a
serial<-->USB converter dongle. Just chop the DIN plug
off, strip the wires and splice them to a cable with the 2.5mm
GPS connector plug for t he D700. <br>
</span></p>
<p><span id="productTitle" class="a-size-large">Note you will need a
5VDC (*not* 12VDC !!!) power source for the GPS. (Additional
contacts in the DIN connector were +5VDC IN & COMMON.)
You might cannibalize an old lighter-socket cell-phone charger.
These are often available at dollar stores (or hamfests) if you
don't have one lying around. Just be sure it is 5 VDC, not 3.3
VDC or some other odd voltage.</span></p>
