In terms of survival, look at it along the lines of the way our Air Force trains our fighter pilots: Speed is Life. The more things you have to slow you down and/or the more you have to defend, the greater the chances you're gonna get got. If it's just a matter of the power going out and...

AI is good at some things - if it's trained against a large enough set of data. What is cannot effectively do at this point is both think and innovate. Had this very discussion with an engineering team prior to posting my reply. We're a ways out yet.

Any tool - be it a hammer, a gun, or AI - can be used correctly...or horribly misused. Unfortunately, power corrupts. In the right applications, AI can be of great benefit to mankind. There are those who will use it for nefarious purposes, however. Society must be ever vigilant against such...

Throwing my 2 cents in: I have a 160-10M fan-loaded dipole combo up as my main HF wire antenna. It's set up as an inverted vee at the moment with the apex around 50 feet. Planning on going 20ft higher when that tower goes up. At quadrature to it will be placed a fan-loaded dipole for...

I replied elsewhere on this topic, but: The base on mine is about 26ft up. It will be around 50 when I get that particular tower installed, Three tuned radials are used...per band. That's the secret sauce. They're cut for 21.25, 24.95, 27.2 and 28.5MHz, Three bundles of 4, and each is sloped...

Back in the day, the bottom 25KHz of the bands was where the good DX hung out. If multipliers mattered, you went where you could find them. Old habits die hard, especially when the rest of the world still operates a given way.

Run over yonder - to the Boat Anchors section of another forum - and look up KW4H. He has a solution to your dilemma and used it to restore the Heathkit CW Twins, amongst a few others. I threw out the idea of using such as a fixed-frequency signal source in rigs such as the FR-101...

This thread is relevant to my interests. Good on OP for keeping another 440S alive and out of the parts bin. I have two of these. One apparently an early model and another, a later. There are differences in at least two of the boards (RF Unit and one of the Switch Units on the front chassis...

My use case may be different than others, but here's the setup: Base of mine is ~30ft up - looking to increase to 50ft at some point. Coaxial choke at the feedpoint and another (unun) choke at the tuner output. Three tuned 1/4w radials per band - 21.25, 24.940, 27.2 and 28.6MHz are the...

If they offered this in a remote-head version (a la IC-703/706/7000, FTM10R/SR) I'd jump on at least one for use with my touring and sport touring motorcycles. There's an ongoing 10M net in my area which I participate in when mobile - and it would be nice to be able to pop down to Ch19 and...

Can't help but think those radios are staring at me. And I'd place the ergos right up (down?) there with the TS-2000. Might be a great package but damn...who thought the idea of a half-melted radio would be appealing?

Thread bump. I was going to start another one on this series but found your post. Had a set (FR-101D/FL-101, FR-101S/FT-201) around 2005-2007. Sold them to a ham in Indiana. Next set I acquired piece by piece starting in 2015 and continuing to last year. Included are the FL-101 w/ speech...

1970 or 71. An uncle gave me a book - "Using Electronics" - which is sitting on a bookshelf next to me as I type this. That was the initial spark plug. Finding a discarded AM transistor radio was the next. I hooked it up to an improvised antenna on my front porch and began prowling the bands...

Right up until the Pd figure is exceeded and they don't. Spec'ing a device with little or no headroom is a sure-fire way to see this happen in a PA strip which lacks active protection. On the flip side: CPI incorporated power-limiting circuitry but also used devices which were rated very...

On most of the better ones. I've had to replace finals on a number of them which didn't incorporate it. Same on a lot of the early solid state, 100w PA ham rigs. HW/SB-104 and TS-180S are two which readily come to mind.
