Recently, I received a note that Chines radio modems are used for telemetry. The note states that these transceivers are operating on our 2 metre band between 144 and 146 MHz. More details are expected. Along with the note, a link was sent with a URL to a Chinese company, selling these transceivers. They operate… Continue reading »

In my humble opinion, Joe Taylor, K1JT, is a true innovator for the amateur service. As a scientist, Joe received several notable awards. The amateur community should be grateful for his efforts and resulting advancement. Many amateurs may forget that our use of frequency spectrum is justified by experiments, with possible spin-off that benefits everyone…. Continue reading »
Celebrating one year of 60 m in The Netherlands with a surprise from Antarctica!
In a recent post, I reported about my situation, comparing it with CISPR limits and came to the conclusion that these limits do not offer the required protection to comply with the European EMC directive.
