CERT Basic Final Exercise 2/10

I had the chance to be a “survivor” of a mock disaster for the Sacramento Metro Fire Station 21 CERT Basic class disaster simulation today. This normally means having a severe injury and role-playing an often uncooperative survivor. I was to be a victim who had a big hit to the head, and was disoriented and wandering. This meant I did not get to be covered in blood, but only sported a large bruise on my forehead. Maybe I should have chosen to have more contusions on my face or something, would have been far messier. Our disaster event was we were survivors along the debris path of a plane… Read More

SDARC Meeting 2/8: History of Phonetics

We had our monthly meeting for the Stockton Delta Amateur Radio Club on February 8, 2018 at 7:30pm. After usual club announcement and business, we were treated to a presentation by Jim WB6BET of the Lodi Amateur Radio Club (LARC): The History of Phonetics. Jim went on to describe DX phonetics. Emilia KI6YYT, president of LARC, also gave a presentation on the USS Hornet, describing its radio systems and an all-women’s QSO event they held there last year. It was interesting to see the kinds of radios they used on ships back then (one slide had a bank of Harris RF-350s). It’s cool that the club meetings are not only a chance… Read More

ARRL EC-001 Emergency Communications Course

Today marks the day I took the final for ARRL’s EC-001: Emergency Communications Basic/Level 1 course. It’s a 9 week course that I started in November and covers a wide range of EMCOMM topics: From the organizational structure of emergency communicator groups to traffic net etiquette to digital modes to message handling to deployment preparation and expectations. It is designed for those who want to volunteer in ARES or another emergency communications group. The 9 week course is comprised of 29 lessons, with an estimate of taking 45 hours to complete. Along the way, there are assignments/activities for each lesson, and frequent check-ins with a designated mentor of the class.… Read More

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

80m RTTY

I found a load of RTTY on 80m band on Sunday night (1/7/2018). I tuned to 3580 kHz and found a particularly strong signal, so I hooked up my USB soundcard to my laptop, fired up fldigi and made attempts to reply, but I guess my QRP setup didn’t get heard in all the pileup chatter. 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!

More CW Practice

Merry Christmas! Today I landed upon a video by KJ4YZI Eric of HamRadioConcepts (https://youtu.be/Jls-PiR-dBI) entitled “How I learned Morse code fast and easy”. I found the title suspect because CW is neither fast nor easy, but he did help me a lot with this simple video. He learned with the help of an Android app called Morse CT that allows him to practice by tapping the alphabet and numbers on his phone. It never occurred to me that I could tap on my phone screen to learn sending. I have been so slow going because the Koch method is tedious and very hard in the beginning. I was thinking I… Read More
