Doing some major pre-planning for the ham radio event I am volunteering for today: determining where the aebleskivers booth is, and when the Abba tribute band gets on 🤪 #hamradio#aebleskiver
Direct generation of radio waves using a special generator:
Next super long wave Grimeton #SAQ transmission on 17.2 kHz will be on Alexanderson Day July 6, tuning of the transmitter 8:30 UTC, transmission 9:00 UTC
Since it is in the audio spectrum, It can be received in Europe using merely a long wire and a sound card input! More specialized loop or active antennas are advisable. #hamradio #electronics
Reading the wikipedia article on microwave ovens and found this sentence in the part describing the frequencies they use:
"The third, centered on 433.92 MHz, is a narrow band that would require expensive equipment to generate sufficient power without creating interference outside the band, and is only available in some countries"
You know what this means? With a big enough amplifier, you could cook your food with a Baofeng.
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.
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! 🙂
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 #hamradio has a spotted history with #foss, 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?
