KA7EXM / Kanga PIC Power Meter Web-Site
The PIC Power Meter started out as an article
in QEX in the May/June 2005 edition. A companion piece was presented in
QST. In conjunction with the article,
KangaUS offered full kits for sale.
Since 2005, over 100 full kits were sold, and another 100+ sets of PC boards.
The firmware was updated in 2007 to include some minor feature enhancements,
including RS-232 interface support. The project appeared in the 2008 -
2009 handbooks as well (give or take). .
Update 3/2013:
I have just a few PC boards and CPUs available. Contact me directly if you are interested.
Update 5/14/2007:
Version 2.0.0 Firmware Released.
- Power Bar: 2nd line of the LCD display shows 0 to 16 "bars"
of power on a log scale. This lightly mimic's an analog meter's
respone.
- Min/Max hold: Remember the strongest and weakest signal
during a measurement interval. Useful for field strength measurements,
tuning up a matching network, etc.
- Serial Port output: All power measurements (Power, relative
power, watts, VSWR) are output at 9600 bps at a regular interval.
Couple this with a PC program and you have yourself a nice piece of
instrumentation!
Availability: Software / Firmware has been posted.
