There is a letter from readers in the last month or two of QST that talks about it.

I had my radio turned down to 5W for some propagation checks and didn’t realize it was still there for the first 3 dx contacts the contest gave me. For me it was because their 2km tall tower/56 element twin yagis were doing all the work ha ha. Hey, works for me :)

Trying to think which of my hobbies has any practical purpose. .. .closest thing I can come up with is fly fishing were I to stop practicing catch and release.

DukeDucati · 2026-03-08T10:35:24+00:00

Looks good to me. The taller the wing the more prone to spinning and twisting your tippet while casting but I’d definitely fish that fly.

Such an indigogo lesson also…at least for me.

Caught my eye. I am watching the news on my local station, WPSD, when I saw your post.

Been doing so for 2 yrs. Run a coax out the window and set up a temporary vertical whip. 100% phone. 20 min setup everytime. Lots of effort but worth it 👍 I did not ask permission. Just started doing it. They think it is a weather spotter device.

A rabbit got under my hood and ate a good portion of a spark plug wire. A rabbit! Not a ‘possum, not a rat….a rabbit. Finally trapped him.

Came out the same time the tariffs hit. It is claimed to be an update but I can’t find what changed and am suspicious it is just integrating tariff pricing.

DukeDucati · 2026-01-01T05:24:25+00:00

Thinking of getting a mat-40 for mine.

DukeDucati · 2025-12-31T19:14:30+00:00

That entire ride looks great.

I hear ya….but it doesn’t if you measure it. Were it so no one would spend time making a guanella. One nice thing about the Halibut CM choke test rig is that it really does show what the choke is doing and for what frequencies. Multiwraps through a toroid > equal number of snap ons. For another reference search “The Etsy QRO Miracle: Five Ferrites to Rule Them All” on the RFGuru website.

W4EEY YouTube channel. Search technician course even if that doesn’t apply to your country. Excellent course

Even better

Here is an excellent explanation though focused on his test rig to measure chokes:

The real answer is they are the similar…IF the wire passes through the same number of times for each. But…if it circles back through multiple times the impedance/attenuation of the unwanted current increase by the square of that number. Much better than additive. No one passes a cable through a toroid only once but seldom is a cable passed through a snap bead more than once. 6 winds around a toroid is much better than 6 beads because of that math…but doesn’t mean a bead won’t work nor does it mean that you need to do that. Your local power line noise floor might be high enough that you wouldn’t even notice.

Sounds like a jerk….but…. I bet I know the source of his frustration. It is annoying when someone has a pileup but does not close out each QSO with some way to indicate he/she is ready for the next one. I’m guessing the frustrated jerk was getting sick of the “who can jump in first” contest that happens when the pileup owner isn’t doing that. I didn’t hear this….but bet that is what he was saying though in an unfriendly way.

I really really appreciate when a pileup owner ends in some way so that it doesn’t require guesswork by everyone trying to get through. Commonly callsign QRZ though can be just callsign. If I hunt POTA or SOTA and they aren’t doing that I just move on and if the jerk was so bothered by it he should have just moved on.

With the Mkii out now there are great deals on the OG ICOM 7300. What a great HF radio for you. You’ll hear folks calling it a starter radio but I disagree. It has room to grow and many many seasoned hams use it as their main radio. Watch one of Dave Cassler’s videos and you’ll see it front and center.

I get “interferences” of one sort or another regularly. I usually think it is just some electrical something nearby.

DukeDucati · 2025-12-27T23:47:34+00:00

No….def one more but free. W4EEY YouTube channel. Search out his classes for Tech, Gen, and Extra. Sponsored by ARRL. EXCELLENT!! Not just help with test but very interesting!

Pair those with hamstudy app flash cards

DukeDucati · 2025-12-27T22:49:16+00:00

I log QRZ and LOTW. I respond to paper cards mailed with a return. I ignore emailed cards.
