Hoovers and Handhelds

/

The German Bundesnetz Agentur has banned the sale of TESVOR model6 robotic vacuum cleaners, because it not only used lasers to chase your cat or dog, it also sported a wireless link, complete with a networked remote control.

It came into circulation without CE mark or any appropriate paperwork regards the wireless parts, so the TESVOR model S6 does no longer makes its rounds. While we could smile about that, the same Bundesnetz Agentur struck closer to home, and also banned the import, sale and use of the popular Baofeng UV5R dualband handhelds. Several Amateur Radio news outlets reported speculations that this may lead to a ban across Europe.

Informed postings on the Ei7Gl blogspot confirmed what Polish authorities found out in tests conducted on imported UV5R radios: Their transmitted spectrum is not clean enough, so the Polish authorities informed their German colleagues, who in turn quickly announced this ban

New Web-Based RSGB EMF Calculator

The RSGB has launched a new version of the Society’s EMF calculator v11d which is now available in a new browser-based version as well as the spreadsheet version. The web browser version does not require you to have Excel or another spreadsheet on your computer. It also has several great new features to make compliance checking simpler and quicker. You can find both versions on the RSGB emf web pages or you can go direct to the new web version.

Novel SSB transceiver Design with only Seven Transistors

/

When Pete Juliano N6QW sat down to design a sideband transceiver for the 20 Meter (14 MHz) ham radio band, he eschewed the popular circuits that makeup so many designs. He forged ahead, building a novel design that he calls Pete’s Simple Seven SSB Transceiver, or PSSST for short.

What makes the PSSST so simple is not only its construction but the low component count. The same circuit using four 2N2222A’s is used on both transmit and receive.
