In an effort to get more people on digital ham radio easily, I posted a video about how to put together your own multi-mode digital voice hotspot device very inexpensively, and with little effort. I have put together several of these and the work pretty well. Kind of like an oil change, almost anyone can do it. I admit, I used to have a purist mindset about ham radio. All these Internet-dependent modes such as Echolink, IRLP, and even analog repeater inter-linking over the Internet had me thinking “but what happens when the grid goes down?” I’ve experienced some pretty bad fails as a systems & software engineer, and also as… Read More

This past year was an eventful ham radio one. As I begin to look ahead to goals and daydreams of 2019, it’s always good to not expect the past to be the norm, but to take a moment and appreciate all the stuff that’s happened good and bad. Thinking back, it’s amazing when I consider HF newbie AD6DM 2017 vs. AD6DM 2018. Here are some of the things I experienced in 2018: Completed ARRL ARES training: EC-001 Introductory Course. Set up a ham Twitter account @AD6DM. First time having my own QSL cards and people to send them to. Had my first CW QSO with AB6ET. Learned the workings of… Read More
Continue ReadingThe Gamification of Ham Radio
I think contest organizations and the ARRL understand one aspect of fostering activity in the hobby. The logbook awards, contests, and sprints have their roots in achievement, competition, and accomplishment. Stanford gaming theorist Jane McGonigal recently spoke at a Security Conference I attended where she remarked on the incredible amount of time poured into online gaming. More than the combined manpower of the largest companies in the world, games contribute literal trillions of man-hours (billions a week) to seemingly “useless obstacles”. Why? Because games bring out a full-brain engagement like few other daily activities. The same concepts are readily (albeit unintentionally) applied to ham radio. Even contests that aren’t scheduled,… Read More

One of the few things I actually took home from Pacificon 2018 in San Ramon was an Ed Fong “DBJ-2” Dual-band Roll-up J-Pole for 2m/440. A vendor was asking me if I needed a cool base-station 2m antenna (DBJ-1), and I said I already had one set up. I recognized the seller’s nametag and said, “But I do know your name… Do you happen to have any of your famous Roll-up J-pole antennas?” He had only a couple more. I knew about this antenna from SOTA YouTubers KG6HQD Jerry and W6RIP Kevin, and wanted to try one since seeing Jerry throw one over a tree and blanket the whole Los… Read More
Continue ReadingCW and FT8 and PSK, oh my!
In the past month, I’ve finally unblocked my antenna issues and made great strides in the digital realm of ham radio. Using the PreciseRF HG-1 magnetic loop antenna along with my RigExpert AA-600 to get the lowest possible SWR, I have found that I can get out to virtually all over the country simply from putting the antenna on the street. The loop only supports max 45W PEP, so it is definitely a low-power antenna. But I can only imagine how it would function if I were in a flat field or on a peak. With gray-line propagation some days, I see strong signal spots via Reverse Beacon Network or… Read More
Continue ReadingSent first SSTV image
Using SSTV for iOS on my phone and a BTECH APRS-K1 Audio Interface Cable (albeit connected to a Kenwood TH-D74A), I just sent my first SSTV image on 145.510 MHz FM simplex. I don’t think anyone heard, but it was a proof of concept exercise. I recorded the transmission on a separate handheld, using a small voice recorder. Despite this lossy recording method, I was able to reconstruct the image pretty well using the same SSTV app. Here is the recording, give it a try with your decoder: Encoded with Scottie 1, try decoding this SSTV transmission with your own SSTV app. (here’s a media file download link) The implications of this mode are fascinating.… Read More
Continue ReadingFirst CW QSO Confirmed
Today I received my first reply QSL card. And for a CW QSO, no less! On March 7, 2018, during my lunch break I set up my mobile 40m hamstick in the office parking lot and surfed around the CW frequencies of 40m (i.e. 7.000 to 7.125 MHz). It was mostly me calling CQ and with no replies, but toward the end of the lunch hour, I heard someone coming in pretty loud, and slow enough that I could (mostly) make out the characters. By the second callsign send, I could visualize: AB6ET. I hoped I was getting it right. When AB6ET finished, I sent out, “AB6ET DE AD6DM… Read More
