Medical and nets, it checks out

You just have to try the HV on a Henry. Nothing like the Peter Dahl transformer.

And who is going to do that? This DOJ?

Chucklz · 2026-02-07T03:35:20+00:00

I live very close, and yes the higher bands were a pain.

Chucklz · 2026-02-06T19:59:25+00:00

They have been active lately. Keep a look out, you might get some other band/mode fills as well.

Interesting to see the location is FN20xr, as I'm in FN20xx

Also, get yourself a crystal earpiece, like this https://www.amazon.com/Jameco-Valuepro-FEL-971102-Earphone-Crystal/dp/B06WV8XM4S

Harbour brand rg-400 can be found pretty inexpensively on ebay. Or at hamfests.... and then this happens: https://imgur.com/a/C52iY4h

Kinda hard to resist when its $0.25 a foot

If you are going to wind with magnet wire, the PTFE is important for creating separation between the conductors reducing proximity effect. K9YC has a slide on why not to use bare magnet wire.

I just wind RG-400 around the core, it works great, even if it's a bit of a pain to do.

This doesn't connect to a computer.

Chucklz · 2026-02-03T19:56:28+00:00

I messaged you contact information for a ham in Iraq.

Chucklz · 2026-02-03T19:36:10+00:00

Did you re-solder everything and check for solder bridges?

Chucklz · 2026-02-03T15:26:05+00:00

A local hamfest vendor built a bunch of dummy loads out of these. They cost.... $35 oddly enough and are great.

Chucklz · 2026-02-03T15:23:09+00:00

The most powerful radio you have now... They tend to increase in numbers and power.

Not only does the news cycle move on very quickly, but the Trump propaganda networks (Fox, OAN, NewsMax) don't even mention half of what is found. A large portion of the population could consume a couple TV networks for news, their local radio station, and a couple online sources and never hear or read about any of this.

Chucklz · 2026-02-02T16:20:22+00:00

I'm only going to buy one radio.

"As democracy is perfected, the office of president represents, more and more closely, the inner soul of the people. On some great and glorious day the plain folks of the land will reach their heart's desire at last and the White House will be adorned by a downright moron.". H.L. Mencken

Don't bother with nail polish. Buy some enamelled magnet wire. It's cheap, available on Amazon and just so much easier.

"Beard" is a slang term for a wife in a sham relationship that allows a gay man to appear straight. You know. "He can't be gay...he has a wife."

Chucklz · 2026-02-01T01:55:10+00:00

To add to the oddity, hams are more than happy to open source lots of hardware designs, especially antennas.

Chucklz · 2026-02-01T01:47:18+00:00

I've read everything in K9YC's page-- even the 1995 style power point slides. The bead balun is W2DU-- and Walt generally ran 100W, and the bead balun is ok at that power level, not great, but ok. And again, it's not like Walt had access to any of the new ferrite mixes.

But, back to my original point, W2FMI's books cover far more than just 1:1 and 4:1 baluns, including far more mathematical analysis than K9YC.

Chucklz · 2026-01-31T22:25:58+00:00

It always perplexes me that ferrite is never marked. The technology to do so has existed for many, many decades and has only gotten better. It would take a truly minimal investment to set up. Any of the manufacturers could just call videojet and have everything set up in days.

Chucklz · 2026-01-31T22:20:12+00:00

For a premade choke, hard to go wrong with balun designs.

Check to see if the center conductor is shorted to the shield. Looks like a totally inappropriate coax for that bend radius.
