However, I was more eager to use my more modern, synthesized ICOM 1C-2AT in order to expand the frequencies on which 1 could work packet. This effort became an...

Broadband Excellence That Takes The Power

KLM's KT-34XA TRIBANDER is the 2nd generation of a unique new series of antennas designed to provide superior broadband coverage on 20, 15h and 10 meters- The combination of lossless linear loading and hi-Q air capacitors enables the KT-34XA to outperform all commercial available tribanders and meet or exceed the performance of a conventional stacked monoband system. The lower weight and windload of a single antenna mean reduced tower and rotator requirements, Thus, overall system costs can be...

Radar Jamming

The battle between motorists and moving tax units also known as radar-bearing police cars continues to escalate. Since they're mostly using 10.5 GHz, which almost amounts to sharing our 1 0.0-1 0.5-GHz ham band, perhaps we should keep up with what's been happening. It alt started years ago with the first police radar units, It didn't take long before Regency came out with a detector. Alas, it wasn't sensitive enough to be of any real value which made it worse than nothing because impressionable...
