Antennas, experiments, engineering and other articles of interest to radio folks. Those opposed to Winlink are attempting to hold removal of the 300 baud HF data limitation hostage. You would think the world of RF connectors of the pedigree of the “N” would rigorously follow the dictates of the standards that define them. Thankfully most do, but exceptions arise and here is one such example of why it pays to “trust, but verify.” Measurements reveal the effects of common mode current on the J antenna. Does one really need to upgrade the antenna that came with your HT? Presented are EIRP measurements of various aftermarket HT aerials to A closer look at type 61 ferrite material in various configurations for RG58 reveals the benefits and insufficiencies of chokes in series. Learning more about several ferrite compositions from the Fair-Rite manufacturer including where to buy them. I measure one example of a ferrite coax choke for response over frequency to understand its suitability for VHF and UHF. EIRP measurements of the 2m end-fed half-wave HT antenna from MFJ aids understanding a dipole is a dipole no matter where you feed it. Thanks to a spiffy new Airspy HF+ SDR receiver I can scratch listening to WWVB off the bucket list. The National Institute of Standards and Technology appears to have the time and frequency broadcast stations on the chopping block given the info contained in their 2019 budget proposal. This is what I wrote to my senator and congressman. DX Engineering supports the build of the Asymmetrical Hatted Vertical Dipole (AHVD) antenna with standard and two custom parts. A writer details how his ham father dissed his family by losing himself in technology. The story serves as a canary in the coal mine for “social media” then and now. Categories Introspection Near Vertical Incident Skywave (NVIS) propagation works wonders when the bands cooperate, but can slam the door shut at any moment. The Diamond Antenna NR770HBNMO paired with their K515S insulated luggage rack mount provides measurable and observable upgrade for my
