Here is a link to to K9LA's "An Introduction to Operating on 160m" A short read. Only 9 pages. On page 6 he discusses why predicting propagation on 160 is difficult. https://k9la.us/An_Introduction_to_Operating_on_160m.pdf This article is over 20 years old so take his description of the band...

Run a good quality coax from the current tower to the new shop. A 200 foot run of LMR-400 attenuation is only 1.4 dB @ 30Mhz. No one will notice that very small drop in your signal. DX Engineering Comparison chart. If you need to bury the coax to the new shop, Bury-Flex from Davis RF has...

I was a teenager in the mid 70's and like many I was knee deep in the CB radio craze. My dad applied for a license (KZX9251). I think it costs $20. My Dad (sk), was WA9DGH in the 1960's. He was off the air since we moved house in 1971 and was an enthusiastic accomplice in my new hobby. My...

All mouth and no ears. ;)

They are not fake. Its just software decoding callsigns incorrectly.

And more. Had to turn the alarm off.

I use the DXLab suite of software to help me chase DX. One of its modules is SpotCollector. I have it set up to sound an alarm on my PC and to send me an email when a DXCC I need is spotted. CW Skimmer and Skimmer for FT8 has been a game changer to help me chase DX. But busted calls are a...

I helped my buddy W3MJ (SK) put up a DB18e. Worked flawlessly for 13 years. I took it down when he died and passed it on to another ham. My friend John NJ3I (SK), installed the BigIR Vertical. Worked great with 40 buried radials. He tried the optional 80m coil but it couldn’t handle 1,500w...

It is working for me. The first pic shows your page when I first open it. The second pic is after I click on “Use mouse to view”

Elecraft K3 I'm primarily a CW and FSK RTTY contester. This radio is the best CW rig I have ever used. Flawless and silent QSK. Each receiver (mine has two) hosts 5 crystal filters and combined with DSP allows you to filters out strong, close by signals to work the weak one. I also like the...

The Voyager craft design started in the early 1970's based on the Pioneer 10 program. No computer aided drafting back then. Pencil, paper, slide rules, and the gray matter of some very smart people designed these incredibly complicated machines. Of course the RF amplifiers on the Voyager have...

The beamwidth of the antenna is amazing. A three element Tri-band HF yagi (20m,15m,10m) beamwidth is around 60-70 degrees with about 7 dbi of gain. Below is a diagram of the Voyager's 12ft. parabolic antenna. Notice the X-band beam width and gain. The precision needed to point that antenna...

I saw that video when it came out. I think the "Copyright Strike" was due to manufacturer's (Tom Evans Audio Design) embarrassment that their marketing smoke and mirrors was exposed. Mark not so subtly said he couldn't understand why the price of that preamp was 25,000 GBP. Mark pointed out...
