Sparky’s Links for September 2024

Here’s what Li’l Sparky stashed in his nest of bookmarks this month.

Carol, KE6SRN filed new reports from Alaska and, closer to home, from Hoyt Mountain.

Savi, W1SAV worked some POTA at Crystal Cove and Rio de Los Angeles.

NASA’s Next-Generation Solar Sail Mission

Tony, K6TTP writes: It seems that hams could bounce radio signals off this reflective sail to communicate with other hams.  It would be a much larger target than a satellite, the ISS, or the moon.  But I think the location is problematic.
Hackaday also posted an article on the sail.

WBCQ: A One-of-a-Kind Shortwave Radio Station – Radio World
There are all kinds of shortwave radio stations in the world, but WBCQ seems unique.
Ask Hackaday: Is Shortwave On Life Support?
Between World War II and Y2K, shortwave listening was quite an education. With a simple receiver, you could listen to the world. Some of it, of course, was entertainment, and much of it was propaga…

Another posting for OLD hams and SWL-ers, like me, who remember the good old days.  Listening to SW in the late Postwar ’40s is what led me to become a ham at age 10 in 1952.  Those days are over but I recall them nostalgically.  They will never be back, nor is there probably any reason why they should be back.  But it was fun once upon a time.

QRPblog: VHF/UHF Handheld Comparison


To the dismay of some and the exhilaration of others, here’s some good dope on some HT units.  May be useful to potential buyers of new/used HTs.

Is Inflation Making Off Grid Power Too Expensive? – Off Grid Ham
Let’s pick apart the phenomenon of off grid energy equipment inflation and see if there is anything to this reader’s theory.

A Reason To Get On The Air – The KØNR Radio Site
I don’t need much but I do need a reason to get on the air. This can take many forms as I wrote in this blog post some time ago. I see quite a few new hams struggling with the problem of “I got this license but now what?” Operating goals or awards are a fun way to keep focused Continue reading A Reason To Get On The Air→

Exploring the End-Fed Half Wave Antenna

Ferrite core

Tony K6TTP sent us this article on the end-fed half-wave antenna written by John VA3KOT for Ham Radio Outside the Box. “This is probably the best overview article on end-fed half-wave antennas I’ve read in many many years. It broadly addresses in brief the fact and opinion that exists in the EFHW world, and explains the complexities, alternatives, and some variations on the type.” It’s a great introduction for anyone considering constructing one of their own. The caption for the image accompanying this post reads, “49:1 showing 2xFT140-43 ferrite cores. No case, insulated wire protects windings from moisture.”

You can tell us about your antenna building adventures on Instagram, Threads and Mastodon.

A New Tool for SOTA

SOTALogs.com is a potentially time-saving tool for anyone who enjoys Summits on the Air. According to the site’s creator Brian Jester KB8UIP/VE3SPG, SOTALOGS is “a super simple 1-page bootstrap site to help create error-free CSV SOTA logs” ready to upload to the SOTA database.  “There are 3 ways to submit SOTA logs: the activator web form, the chaser/s2s web form or via CSV/TSV file.  Some might hand craft their own CSV in Excel, but I’m not fan of that, so I made tiny site to help make things easier.”

Thanks to Brian for his work. (Originally linked on the SoCal SOTA Groups.io.)
