It was fascinating to connect the VNA to a manual antenna tuner in line to the antenna, you can twiddle the knobs and see the SWR waves go up and down as you manipulate the inductor and capacitors. I’m new at this and never used a manual antenna tuner before this. It would have been frustrating to operate the antenna tuner blind.

I bought an S-40B with some good potential off eBay about 10 or 12 years ago and spent some time recapping, aligning and generally getting it into what I consider excellent condition. I wound up replacing the toggle switches, one of which was broken. Amazingly, these were still available in their original form. Alignment is an art form. I have spent countless hours aligning everything from S-38s to Hammarlund SP-600s (48 adjustments in the RF section alone). My feeling is that dials were designed using a prototype chassis. Given the vagaries of parts control, they just don’t fit all the production units very well. Oscillator points should be adjusted about 10- to 20-percent in from each end of the band to get the best fit throughout the band. The frequencies specified in the alignment instructions should serve only as starting points. Once the main tuning was aligned as well as possible, I developed frequency graphs on the bandspread logging scale. An outboard crystal calibrator is helpful for this. I restrung the tuning and bandspread dials using 50-lb test, microfilament, braided fishing line. This is much better than regular dial cord, as it provides exceptionally smooth tuning with minimal slack or backlash. The bandspread on the S-40B lacks the nice flywheel present on the original S-40. My unit is also setup to plugin an optional outboard Heathkit GD-125 Q-multiplier. This improves selectivity. Many years ago, a ham buddy taught me how to tune single sideband using combinations of the sensitivity and pitch controls, and CW and AVC on/off switches. For tuning SSB as well as narrow bandwidths produced by the Q-multiplier, the main drawback of these old radios is stability. They drift significantly during warmup, and somewhat less thereafter. All things considered, the S-40, S-40A and S-40B were excellent cost-performance tradeoff options for hams and SWLs 70 years ago. Yours, sir, is a beauty and must give you lasting satisfaction in its restoration.

I know this is 1 year old but I hope you see my comment. Thank you very much for this video. I had the same issue you had. I did what you said and it fixed this problem. My SWR hardly flickers now. I had to make sure the split band was within the ham bands and I also turned the split function off. Both had to be done in my case. I have a random wire 35.5 ft antenna with 9:1 unun and common mode choke on the feedline near the antenna and transceiver. My antenna runs along the wall in my room. I know it is very compromised but now I know my SWR is under control and I might have a chance to talk to someone with the SWR under control. I am handicapped with arthritis and have a heart issue, that's why I have it inside. Makes it a little easier than outside. Thank you very much again for this video. It helped me very much. I have had some strong signals come through on my indoor antenna, too.

One trick is to ground the shield of the cable , so the metal of the car provides a good ground plane, and this is especially important of you are using an HT. The variation you are observing is because of a floating ground. If you don't want to ground, the ferrite method you used helps.

Lots of S-40 turn up... at least around here. (noting rare for sure... and not a great radio either.) I think it's mostly because of the Hallicrafters name.

Come on now! No disrespect, but I can't believe that such an intelligent technician couldn't figure out how the carrying handle on this radio works and made a totally incorrect assumption that it was poorly designed. A world-renowned radio company, Nordmende, would never design a flimsy non-functional handle, such as you assumed, for any of their products. The HANDLE is designed to lock in place at the two metal posts on each side of the radio body when you firmly pull the handle away from the posts. The handle doubles as a stand to raise the front of the radio when it is laid down.
@radiotopics18743 ай бұрын
Yes, thank you, I'm aware of how to attach the handle and what its function is. There is a spring metal strip inside and on either side of the narrow slot in the handle that is designed to hold the post on the side of the radio in place. When that loses its "spring" it no longer holds the post in the narrow slot in the handle, and it's free to fall out of the larger slot. I agree that it's not so much a design flaw as wear with use. It may happen to your radio some day. Better to give buyers a heads-up that it could cause the radio to drop to the floor than not point it out at all.

I've looked at the literature on the manufacturer does not claim that it is suitable for transmitting at those frequencies rather that it is suitable for 6 m, 2 m, 70 cm, 33 cm, 23 cm. The only claim for lower frequencies is for receive, which is white band from approximately 25 MHz up to approximately 1300 MHz. Biconicals and the variant the discone are extremely wide band antennas and can be suitable for transmitting over very wide frequency ranges. Unfortunately most of the commercial offerings have insufficient elements to make them very efficient with a solid cone and disc being the optimal design.
