CAKE Crumbs August 12<\/h4>\n

Tom  KW6S and Ron W6WO  were the only ones present today but of course weenjoyed some good conversation. Tom brought a power amplifier for 6m which he made from scratch 40 years ago. It looked brand new and demonstrated construction to a most professional standard – a truly fine example of home brew.  Tom also showed a  WSPR lite 200mW beacon product and outlined his plans for assessing  antennas, we look forward to hearing more.<\/p>\n

\"6m<\/p>\n

We discussed advances in solid state RF power devices and in particular those made by IXYS. These are designed for non-linear PA operation in class D and E that operate at KV levels and at frequencies well above HF. Their use in the ISM band 13.6 MHz is of particular interest. The driver can be used as a standalone QRP amplifier with a CMOS square wave input. Ron mentioned he built one a few years back that produced  sinusoidal output of 15Watts after filtering- mW input to Watts out ! Both of us are well aware of the special need for a clean DC  power supply and cautious pulse widths to avoid destruction.<\/p>\n

The article entitled AREDN  Amateur Radio Emergency Digital Network in the  June 2017 QST was discussed.  Tom recalled that we had considered a similar project in the past but had not acted on it as a regional project.
\n This final sentence of the article may revive our interest. ” Plans have been formulated to link Ventura and Santa Barbara counties in 2017 and San Louis Obispo, Monterey , San Benito and Santa Clara counties
\nin 2018 “. Clearly this prompts the question “Why not Santa Cruz ?” Interest anyone ?<\/p>\n

73 for now, we  hope to see you on Sept 9th<\/span><\/span>, same time, same spot on the dial
