True story about a 16 pill toshiba box. I built one for my buddy a late sk, he and i were dicking around with his station, switching stuff all around etc. we finally went to re key to test and we had really poor receive. We keyed the 16 pill and my locals were saying we sounded all fucked up...

3 available now

The typical hg 4 pill now, if they are the c variant, is 800w or so. Toshiba 5 pills routinely did 1-1.2kw. Crusher made alot of posts years ago about the hg's. He found out, along with alot of others, just matching the pills, while crucial now, is not enough. Every part needs to be matched to...

@nomadradio I have a 3D printer, get me the file or get me a cover I could probably make you the file. If not just give me the STL and I'll print it for you see how it comes out

Yup. People forget that gain and efficiency are separate things

Speaking of drive, simply stated, a biased amplifier takes less drive than an unbiased one.

Usually 10% of the output power is a good start for input power. So if you have a 450 watt amp 40 Watts going in is not unreasonable. You could also use less. Set carrier power to 25% of max pep

Great guys at penta. I buy loads from them. Even the big stuff has been great in spite of the naysayers

My back hurts looking at that thing. Makes me wonder if there was a contest to build heavy 811a amps that i was unaware of. The heathkit warrior was way too heavy to make the power it did.

That is the cleanest maco i ever dun seen

I seem to remember opening up an amplifier like this a long time ago and somebody had used some kind of a tin can as a shield for one of the tubes I don't know if it was a mako but I remember seeing a tin can bolted over the deck over a tube like literally a small soup can. It might have had...

Well when I look at those antennas, it looks as though both the stud mount and the pl259 mount both rely on grounding a ring on the base of the antenna. I always had fantastic look with the Wilson rooftop mount. As I went down the rabbit hole this week looking at factory roof mounts there really...

Does anybody have any first-hand experience with them? I'd like to know specifically if I can use the Wilson mounts on sirio antennas

My plan is to get one of the foldable ones with the lever, I know they have a couple where you can adjust it by unscrewing the base, like the large plastic part and then rotating it or moving it around and tightening it back up. I'd rather have the lever. It seems as though I could stick one of...

I've been thinking about mounting a roof mount sirio antenna on one of my vehicles. I like the size of the base and I like the fact that they have their own internal matching device so they do tend to tune very well. I have not been impressed with the quality of Wilson's in recent years. All...
