Tuning SWR with an Antenna Analyzer

If you’re at all into antennas aside from your handheld rubber duck antenna, you should try to get an antenna analyzer. Here I am using a RigExpert AA-600: Before using this device, I would just go by the radio’s SWR reading (a poor display of SWR “bars”) to determine if I was close to resonance. The quad-band vertical antenna I have supposedly works with 10m, 6m, 2m, and 40cm. I never had much success with adjusting the end tip of the antenna for 10m until I started evaluating readings using the AA-600. My target frequency was 28.400 MHz for the LARC weekly 10m net, and 28.457 MHz for the SDARC… Read More

Turns out, January 6-7 was “ARRL RTTY Roundup“, a nationwide contest to make contacts in the digital format, so it was easy to catch the conversations on almost all HF bands. I found the CQ‘s in this format a bit odd, and didn’t really know how to format my responses or how to call… Read More

New Callsign: AD6DM

The FCC has granted my request for new vanity callsign: AD6DM Why the new callsign? I wanted something easier to transmit in Morse code. But also, the initials make it a true “vanity” callsign. Truth be told, I applied for a 2×1 callsign and AD6DM was my second choice. But I got beat by a club for that shorter callsign. Those 2×1’s are really in demand! The migration to this new website domain is complete. The old site kf6ujs.net will remain for posterity while this site continues and grows as I do as a ham. Thank you for visiting!
