What saddens me is so many hams think a dipole is best because it presents a "perfect match" of 50ohms. Wrong. A dipole is roughly 72 ohms if you are lucky and wildly different depending on height and structures nearby.
Yagi antennas are even worse depending on the design and often need an antenna tuner hidden at the antenna. Get the lowest loss feedline you can use and don't feel guilty about the tuner in the shack.

This can't be good, and it smells of a breach or being pwned by ransomware.

Sent some emails today looking for a local tower rigger to fix my busted 6m beam... Hopefully the rigger who put it up in the first place is still in the business. Also sent an email looking for a replacement piece from the 6m beam manufacturer..]
I love the cherry picker idea! If only I knew someone with a cherry picker who could help! 🙂

At the AMSAT Forum at Hamvention on Saturday, I’ll be showing off this prototype 2U CubeSat Simulator.

If you are there or stop by the AMSAT Booth on Friday or Saturday, make sure you say hi! 🛰️📡😁

HamClock is easy to get going, but (a) any chance there's a retina-friendly option, and (b) is there a friendly fork where the source code is maintained somewhere in git, instead of in tarball-form?

@geerlingguy I don't know how much ham radio you're into Jeff, but by and large has a spotted history with , often because of the possibility that the software might end up being used commercially or that a bad actor (read: entrepreneur) would try to profit off the work that hams donate to the community under the general non-commercial nature of amateur radio.

Good news, the radio club president (KR3LL) and friend works at Kicker and took my LCD module and de-soldered it after which I was able to complete the assembly. It all fits in the case and aligns perfect. I was able to tune it fine. However I'm not getting any RF power out, I can receive fine when connected to an antenna. Do you have any recommendations for tracing the issue?

I need to take the "Big Dog" out more often. It handles the bands so smoothly into an using the 49:1 transformer and easy sending using the American Morse Equipment

I haven't used Walt's 100 Watt 49:1 transformer in awhile. Going to take out for a ride today to see how it handles this morning's band conditions.

Rough day for most activators no matter the band. Even tough for operators. Still nice to enjoy a beautiful day.

First ever #summitsontheair station on the summit of Punta Maggiore (IS0/IS-064) in #Sardina (970m). I made 8 SSB contacts on 14MHz with my Elecraft KX2 and EFHW. Pathless scramble to the summit 🧗‍♂️🏞️ Thanks Chasers! #hamradio #sota #italy #mountains #hiking

As the #solarcycle25 #geomagneticstorm was raging this morning 1400 UTC 10:00 EDT, this was me waving Goodbye to the 20 meter band this as my #WSPR beacon showed fading band propagation. #AmateurRadio #hamradio

Got some clips designed and printed to mount my radio in the Honda Odyssey. It’s a good fit! Now I just need to figure out a solution for the mic.

Since my portable shortwave receiver is hardly picking up anything on HF (including no WWV signals), I think I'm going to wait a bit before digging out my antenna and related gear for working this month's #SKCC #HamRadio weekend sprint.

And 20m went KAPUT. I've succumbed to Mother Nature's #geomagneticstorm. Running 20m #WSPR simultaneously with #FT8 to see what pans out on this #parksontheair #pota activation. #amateurradio #hamradio #solarcycle25 #spaceweather
