Second KH6WZ APRS Unit Completed   Leave a comment

KH6WZ APRS Unit Two (KH6WZ-5)

My “high power” version of the tracker box is complete. This unit is housed in an aluminum instrument case, and uses a mobile radio (Radio Shack HTX-252) with 10W and 25W capability for remote locations. The GPS unit is an old Garmin Street Pilot Color Map.

The bottom of the box (on the left) is used to store cables, the original microphone in case I need to use it as a “radio,” a GPS and a two meter whip antenna. A gel-cell would fit nicely in this space for “truly portable” operation.

CEO Dave Sumner Plugs Ham Radio and DIY on Urgent Communications Site   Leave a comment

ARRL CEO David Sumner – K1ZZ – wrote a great story on Amateur Radio and the hands-on experience this technical hobby – and free public service – provides.  Click here to go to the Urgent Communications story. . . .

But – Dave did not mention what’s going on on the ham radio microwave bands. Click here to visit the San Bernardino Microwave Society (SBMS) and the 50 MHz and Up Group and the North Texas Microwave Society (NTMS)  to see what we are doing on the frequencies way up there. . .
