    For an antenna, 5 years is nothing.

    I found the Stauff clamps and they ain’t cheap.likely why the plates come with the indoor type instead of the PA type. Until I find a better solution I’ll likely replace the 4 end-cap halves that are more exposed with new PP clamps ends.

    For an antenna, 5 years is nothing.

    Thanks for the replies. I went through my files and still have receipt. Those green block pipe clamps (posted by SP5IT above) look like the clamps that came with the boom plate I ordered five years ago. This was the first time I’d been up close since I put up the dipole. I will contact the...

    For an antenna, 5 years is nothing.

    While wrapping butyl tape on the terminals of my OCF atop a ladder yesterday, I noticed the 20m aluminum dipole (attached same mast) a few feet below. The green, polypropylene block clamps holding the 1" elements had a white film. After some wiping & scraping, it was apparent it goes...

    Is this a good place for VM/hypervisor project discussion?

    I think of the televised early space flights where Launch Control had many computer displays. Writing stuff down helps me organize and then recall how I made something when it's repair time. Thanks for posting. there's lots of talent in your post.

    Keying Circuits for sweep tube linears

    I used the small keying Board Nomad suggested and it worked very good. It's small, reliable and neat. Better than anything I could make for sure. A time saver to boot.

    Heathkit HO-10 Monitor Scope for HF

    Time passes faster with age. Scope rebuild was successful although I only had 1 go around with it on Transmit w/ amp. Screen view a bit small but basic good-bad is discernable. My 10-40 OCF long leg is still down. Hoping to re-hang all new hardware this weekend. I have a separate 20m dipole...

    Is this Progress?

    The long end of my 10-40 meter OCF antenna came down about 6 weeks ago and I’ve geared-up to rehang it. The long end is approx 75' AGL and attaches to a chain-link fence rail atop a cliff 40' or so behind bldg (5 story) so it requires a fair amount of planning to shoot some line over & pull the...

    CRL rotary switch RF ratings

    Yes, I understand. The unused metal on this wafer can be an issue. I'll keep looking for a better switch with unneeded metal to add the extra input. Stuff like this is getting scarce. Took me a long time to find a progressively shorting wafer.

    CRL rotary switch RF ratings

    I'm replacing the Bypass/Tuner Input switch on my Dentron GLT-1000c ATU to add another input. The new switch is a CRL 2500 series. It is no smaller than the original switch. Can I reliably put a kw through a 2500 switch deck in an ATU for HF? I've owned a few Dentron ATU's that have these...

    Tube swap soon 4cx300A to 4cx300Y

    Preparing to install new pair of 4cx300y tubes (rated 400w, packed in cans, 1 army green/ 1 silver color). This will be my second tube swap with tetrode amp. When I first got it working I used an old pair of 300Y's to get it going before I installed new 300A's. Past month or so I've got the old...

    Down Florida way.

    This is Homebrew category, at best. For the last several months I’ve been watching Marty None videos on YT. They are very entertaining but I’m gob-smacked by the variety of amps he gets to work on. Florida must be far different from up North. His latest video is a Henry 5k. Yes I subscribe...
