an old Byonics MicroTrak 300 APRS tracker and a couple of
different USB GPS's. Is there a cheap/fast/good way to adapt a
USB GPS for this tracker (and set the baud rate to 4800)?
<br>
<br>
All that comes to mind is an Arduino project but that would bring
on additional issues such as power requirements, RFI, size, and
weight.

Thanks and 73,

<p><font face="Arial">Theere is no practical way to convert USB to
serial without some sort of computer or computer-like device
with device-specific drivers. It's going to be far cheaper and
simpler to just use a native serial GPS device. The Globalsat
BR-355 min-puck GPS device is available on Amazon for $36 or
so. This is the serial version of the very popular (and
excellent performing) BU-353 USB version. Just provide 3-5 VDC
and it "automagically" starts spewing out 8-N-1 4800-baud NMEA
data.<br>

<p><font face="Arial">The USB version (BU-353) is now selling for
$10 less. This is truly perverse, given that the USB versions of
these devices are actually a serial device with an additional
serial<->USB converter chip inside. I.e MORE hardware
inside. At one time, the serial and USB versions sold for the
same $30 but I guess the demand and production volume for the
serial version has declined.<br>
</font></p>
<p><font face="Arial">If you are truly adventurous, you might crack
open one of your existing "USB" devices and see if you can
bypass the internal serial<->USB converter chip and get
at the original native serial data stream. [Normally, the
serial<->USB conversion is done with the same Prolific or
FTDI chips used in serial<->USB cable dongles.]</font></p>
