I got mine on ebay here: 5/ea VK200 STYLE FERRITE CHOKE 2 1/2 TURNS 24GA WIRE | eBay As they sit they measure right around 15uH. You can alter the windings to gain or lose inductance.

If AMPOWER was the dude I saw in a video not too long ago standing under some trees touting himself as some sort of amplifier guru, then I will never own a Galaxy product again as long as he's employed there. They guy in that video was beyond clueless, so I can only imagine what his input into a...

You must have missed my last post as well as Audioshockwav's. Why will they be "forced" to go that route when, as just described, there are already FAR superior ways to get that power for less money and effort? Even if a builder wants to go the BJT route instead of MOSFETs, there are several...

I've received a project box and I'm in the process of drilling it for the filters.. I also have found a good heatsink for the amplifier, but I haven't drilled and tapped it yet. I just got back from a weeks vacation to Gulf Shores AL, and working two jobs has been keeping me busy lately. With...

^It just helps ensure a good ground.. it's optional unless you find through real-world operation that your grounding needs improvement.

IDK.. looks overly complicated and not all that cleanly built to me.. soldering still seems a tad sloppy, but it is far better than that other pic.. The future of amps is in LDMOS technology.. As it is already being experimented with in Amateur amplifiers (working on an MRF6VP11KH design...

Not exactly new, but new to me. My buddy showed me this the other day I nearly fell over laughing.. hilarious! Ignore if you've already seen it.. Everyday Normal Guy - CollegeHumor Video

Probably better that it not go in your pocket.. or any other chainsaw for that matter, no matter how tiny. That's the moral of the story right there.. and IMO it's a damn good thing that informational videos like that exist as a warning to the world about the dangers of pocketing a running chainsaw.

Unfortunately, with too much simplicity comes a profound lack of compensation for all of the myriad of variables at work in an amplifier, and that lack of compensation manifests itself as problematic output and other issues. If one were to sit down and really calculate all of the stuff going on...

Personally I think a tuning function on both the input and output is a great idea.. As was just said there is no "one size fits all" in real world designs, it's always about finding a point with the least negative aspects and the most efficiency. Also, there is always variation in actual...

Here y'all go: The End

Seems to me that if only more builders included a single strategically placed variable capacitor (cost ~$2.00 in the worst case) in the input network of their amplifiers this would become one of the easiest issues to correct.. just give that cap a twist until you read the lowest input SWR. Then...

Nice.. lovin' that Browning!

I'm not an expert in antennas or transmission lines, but I do know that specific lengths of coax are often used for impedance matching instead of the standard binocular transformers in many VHF and UHF amplifiers, so Captain Kilowatt's explanation is making sense to me. Doc was saying something...

I've had a couple systems do that, where they throw a BSOD even when booting to a setup CD. In those cases I took the drive and added it as a secondary drive in a different machine, destroyed the partitions on the drive, created a new partition or partitions and formatted. After re-creating the...

I own a company that does laser shows, we build all of our projection systems ourselves: (Always gotta show off a little ;)) We're working currently on getting into the business of medical and industrial RF-excited lasers also, we've got two prototype CO2 laser exciters going...

You're a better man than I Tony. I really do wish I was capable of laughing life off, as you're right it's all a man can really do these days to keep from crying.. Shit's FUCKED up here in America, and watching most of the people in this country pointing fingers at all the wrong people and...

No apology necessary.. I shouldn't have posted my opinion in a joke thread anyway. I realized that once I had already posted, but it was too late to edit. I'm raw because I've been seeing too many ridiculous statements all over the place (not just here) about the state of things, comments that...

I like LMR-240 myself for HF work.. LMR-400 is great, but stiff. I don't have a very long coax run between my antenna and my rig, only about 60 feet, so for HF use I haven't really needed anything with uber-low losses. Personally I don't find fault in finding ways to improve antenna system...

Yeah.. so the entire recorded history of American greed (all 200+ years of it) had nothing to do with this mess.. It was all Obama. Single-handedly. The idiots running the financial sector had nothing to do with it.. it was all Obama. The folks that caused the housing bubble and it's...
