why have any of u not pointed out to him that u cannot title a video "PL259, Install a PL259 the easy way, Coax connector, PL259 with no soldering" then proceed to use soldering at the end ???

Thanks for this! working on my old 2036A and also a purchased old 2036. Wonder if you have any ideas why receiver sensitiy would be rather poor on the 2036. Its not dead but way down on a given signal compared to my good 2036A.

Can the tones be adjusted to another tone or do you have to change something else ?

Yet another testimony in favor of the horizontal loop "skywire". On the low bands, it acts like a highly efficient NVIS "cloud burner" and on higher bands it throws out 360 degree lobes aimed right at the horizon for excellent DX performance. Just be sure to disconnect your radio equipment from the antenna when not in use and to ground the Antenna .... lightning strikes within a few miles induce huge currents in this design. For fun, use 450 ohm feedline and rubber band a florescent light tube to the feedline for a cool flashing light show during storms at night.

I have a crapsman that has the exact same problem. The grass will build up under the break/clutch linkages. It will be like shoving a grass brick under the linkage, and the belt will not fully engage to drive the tractor. I have to clean mine out about every couple of years.

You can grab the Allen wrench short side with a small vise grip or pliers. That will provide torque

I just picked up one of those on ebay, whoever built it did a fantastic job, no cold solder joints, or anything like that. Once I cleaned off the dust, cleaned and lubricated the switches and variable with "Deoxit" the meter looks brand new, I don't think the builder and all the other hands that used it over the years didn't use the meter very much, it's a well cared for meter and I absolutely love it!. Great video, thanks for sharing!👋🤠⚡️🎙

That was the best explanation and tutorial I've seen done. Great job!. I suggest making your own wrench for these to tighten. I used one of these compression connectors and like them.

The shift differences of 1khz to 10khz of which you spoke sound like the crystal may have become slightly out of parallel, or more in parallel. Grinding on wet dry sandpaper seems less than ideal, since it’s hard to keep the sandpaper perfectly flat, even with the glass underneath. I’ve seen it when trying to flatten knife blades and chisels for woodworking. I was going to try this with crystals on a fine diamond stone snd see where it gets me. I may try with HF etching, even though that stuff is a bit unnerving with the bone damage it can cause. there are a ton of 7500mhz and up crystals out threre, no so many in the 8-9mhz range. I’ve got some gonset gooney birds I’d like to get on the air, and would love to have a few more useful crystals for 2m and 6m for them. Thanks for the informative video!

I wonder if you could set up a sputtering chamber, or make some other way to plate the flats on a crystal in order to bring the frequency back down? I’ve seen in a friend’s lab where they had the ability to do this in order to get samples ready for electron microscopes.

Hello Robert. Found this in the archives and what caught my ear was you saying you washed it in a tub??. Very interesting. I have a smelly BC-348 that had a mouse nest in it . I am rebuilding it would like to know what liquid you used to wash it that would be safe with the electronics. Many Thanks and I enjoy your videos. 73

The high tap is around 4K the LS-3 should do fine there , at least mine did I used 600 ohm headset as well both were pretty loud I agree on the amplified computer speaker as an easy fix, you can also use a mini guitar amp, cheap off of ebay and work well also, The Fender amp has an aux headphone port and you can plug in an 8 ohm headset there, 73 J

I picked up a IC211 at a hamfest but the display only changes if I hold in the lock button! It does not lock it but instead makes the display move with the encoder. Also the encoder is very very stiff. What is the best way to fix that as I have a couple other Icoms doing the same thing.

Hi A different topic I know but you hv covered it before. I hv 2060A. Heathkit. I use it to tune before using my sb1000 amp. I made a chart for three sections on each band. Using the chart as a starting point and then adjusting c1 and c2 for lowest swr’s. Here is where I am confused. In the manual, it states c1and c2 dials should be set to 100 to provide max capacitance. ??? Next is the sensitivity knob, how is that used? The manual is very brief on this. Thanku so much. Billy

Hi. I hv a 2060a tuner with my sb1000 amp. I hv always tuned by making a chart for each band. Inductor first, followed by transmitter(c1) and antenna dials(c2). In the manual, it states to tune c1,2 to 100, for maximum capacitance, then tune the inductor?? Add to this, the sensitivity dial. It states, adjust as needed. How does this work? Thanku for any help. Best, Billy N1mrk
