Gary - I have a Goldstar OS-9020A that may borrow (or buy) if you think it meets your needs. No probes. For example: https://www.ebay.com/itm/113863681496 - Jef

Thanks Stuart! Good info to file away for when it might be needed. - Jef

Indeed! That would be a fun project. I like the built-in anti-kerchunking and how it enforces good operator practice such as waiting at least a half second before talking. And the elegance of requirin

Nathan, if you think having a repeater with no PL tone is interesting, take a look at this info about the Seattle Repeater Group's system: - Jef N5JEF From http://www.qsl.net/srg/index.html On Wed, Ma

I should probably mention also that the inverted V configuration for NVIS is very easy, but not ideal because it can pick up significantly more noise from (1) moderate distance lightning storms, and (

That's a handy way to set up for NVIS in the field with only a single (central) support. The important thing is to get the center up at least 1/8 wavelength above the ground for efficient NVIS--so at

A couple more attachments for anyone interested. These provide a more rigorous discussion of NVIS in general, and antenna height in particular. Short story on antenna height: A horizontal antenna betw

Dennis - I am pleased but surprised by your email and your interest in NVIS at this time. Two years ago, on February 21, 2018, I had requested and argued that #NVIS be one of our group keywords and wa

Jim - Thank you very much for speaking up on behalf of science, reason, and best practices--as we currently know them. That's nice to see in these times of extreme hype and popular echo chambers. - Je

Brian - The choke really should be at the antenna feed point. It is intended to present a relatively high impedance at that point, and minimize common mode radiation from the feedline. What's your hig

Nice! +1 for real actions to promote community safety! - Jef N5JEF / WQYJ498

Ah, that's the GMRS repeater at Jim and Sharron's house -- Iron Mine. Excellent location. - Jef

I don't recognize the "Mountain Top" repeater. Which one is that? Maybe its users could contribute for a back-up power system...? - Jef N5JEF, WQYJ498

I heard you like examples, so here are a couple more... A second round of testing by US Air Force engineers has resulted in the identification of an additional seventy-five 70 cm repeaters in Northern

Brian - I have heard from various persons who have been "requested" by the folks at Beale AFB that they reduce their ERP substantially. Just this morning, I saw the following in my weekly RepeaterBook

The strongest argument for GMRS repeaters in our area is that they can run full 50W, in contrast with our ham repeaters on 440 that are crippled by Pave Paws restrictions. The other reason is that fam

Good news worth sharing: Two sunspots of reverse polarity have been spotted [pun intended], indicating that the current solar minimum should turn around normally and peak in 2025. This should help put
