Here is a nifty code practice program called ZZCODE. Click the button to download ZZCODE.ZIP, which contains the source code, ZZCODE.BAS, and an MS-DOS compiled executable, ZZCODE.EXE. These files must be extracted from the ZZCODE.ZIP archive using PKUNZIP version 2.04g.
Also, look at my comments on the "ARRL-Recommended" power connector.
Digital, analog and RF circuit design.
I now work for Raytheon Systems Company in

Tour de Tucson APRS map, November 22, 2014. †
This web map needs some filtering. On the upper right side are some icons, find the one for "filter", click to open the filter list. The box for "All stations" should be checked. One the right side of the items in this list is a red down arrow, click this arrow for the following items: Igates, Difipeaters, Station type: Weather, Station class: AIS ships. These should now be red items below "and not". Check the boxes for all of these items, and they will be excluded from the map removing unneeded clutter.
