Good Morning! It's January 1st, 2025, and I'd like to wish you a very Happy New Year! I mentioned on Patreon yesterday that, in a sense, I’m happy to see 2024 in the rear-view mirror. Frankly, it was a tough year for our family in many ways, but even amidst the challenges, there were moments of celebration and joy.

Todays #POTA activation was at GB-4807. I activated with my mcHF, homemade in 2015, on the higher HF bands with 10W CW.

A added bonus was meeting up with @qrper.bsky.social Thomas K4SWL (M5SWL with his UK call), as well as Bob M6BOB. #hamradio

Watch Out: “Gift Card” Scam Emails Targeting Hams
by Thomas (K4SWL) Lately, I’ve been receiving emails that look like they’re from ham radio friends — complete with their name and callsign in the “from” line. At first glance, they seem legitimate. But when you check the actual email address (not just the name that shows up in your inbox), it’s clearly not from them. For example, the "from" line might read, "Thomas (K4SWL)" but the email address is something more like abc4567@gmail.com.

Getting there, however, takes a little planning.

The previous morning, I'd planned to use my Xiegu X6200 but discovered the battery hadn't charged properly after a firmware update–not the radio's fault, but my own for not checking the PD power supply I was using.

Amateur Radio Has Never Been More Affordable — So Why Do Some Things Seem So Expensive?
by Thomas (K4SWL) When I meet a newly minted amateur radio operator, I often start by telling them, "You couldn't be entering our community at a better time!" And I really mean that. We have incredible support communities, both in person and online. Amateur radio has become far more accessible than it once was. And the cost of getting on the air has dropped dramatically.

I didn’t have enough time in the day to travel further afield than my local Blue Ridge Parkway—my park-away-from-home these days—so I headed there with a field kit packed in the car.
