Solar Power Ham Radio...

It's about time for some ham radio news!

Last week I dug out the old (1970's) Heathkit HW-8 rig, in preparation for Field Day, a communications test held in June. During the weekend event, stations from all over the country try to work each other using a variety of portable, emergency and home powered equipment.

The HW-8 (smaller green radio in photo) puts out 4 watts, and last year I worked over 80 stations. In my testing this week, I worked stations in Japan, Australia, Alaska, and South America.

To give you some idea of the power level, a 4 watt radio is the same power as a night light bulb. My regular station is the equivalent of a 100 watt light bulb, while the maximum power allowed is the same as 15 light bulbs, 100 watts each!

For hams reading this, I use a solar panel and 5 ah battery for power. The keyer (blue box next to clock) is an old MFJ model that runs forever on one 9 volt battery. Antenna is a 40m Ham Stick with 2 radials. Everything but the antenna fits into a plastic tool box.
