Disc caps are micro-phonic, likely the reason why they were fixed in place using wax. They do the same thing for air coils, sometimes also with a bit of foam in the coil to stabilize the windings. That cold solder joint looked like it was around for a while, really _wallered out_ that PCB contact point... Whatever you can find that stops the KZbin ban-hammer... it's all fine by me. Cheers,

[@MrHBSoftware]

nope...maybe in rf frontend they do it for that reason....but NOT next to the output transistors

Hi Shango. I have that National Panasonic radio R 441 B. It has a "hidden" SW antenna on the front of the radio. Lift the bar that wraps around the radio from the bottom and the stations will come in much stronger. I think this radio was made in 1962.

[@waltschannel7465]

VERY cool radios!! Reminds me of the electronics departments of local discount stores we had, as well as privately owned drug stores. Sam Walton prolly carried these! 😀 You have a very fast brain, sir, to narrow down the trouble that quickly in that Panasonic!

[@JerryEricsson]

I watch your videos every day. some have passed through my computer nearly a dozen times. I love them for entertainment value, and I find myself being a bit jealous at the number of stations available to you folks on the left coast. Here in South Dakota, (not the end of the world, but you can smell it from here!) we get sparse radio reception, and our little ranch house with a steel roof, and clad with aluminum insulation I can only get two stations in AM and zero in FM. So it is, I have built an internet receiver so I can listen to radio from around the world, much as I did when I was a boy with a bedroom on the top floor of an old 3 story home situated atop a hill just outside town, back then my Shortwave set could pull stations from around the world, what a thrill that was, and if I could pull in HAM operators, why that added to the joy of the day. Today I have my HAM ticket, and a few 2 meter sets but nothing for long range, and now that the bottom has dropped out of my income, 2 meter is about all I can play with. I am also the only one in a 30 mile area with a ham ticket, so I really have nobody to talk to with my two handheld. My mobile is in our Motor Home, as we used to live on the road before Workers Comp informed me that I had retired and cut my pay in half. Ah well shit happens when you get old, sometimes you expect it, sometimes not. Thanks a million for the videos, when a new one pops it really makes my day!

[@a.fritzbecker8986]

Just run an external antenna out in the yard, with a feed in wire, that will solve the problem with the metal roof.

[@ShyMagpie]

What on earth is that "This is only a test" thing? I remember when you first tuned into that frequency in your 1937 CO-OP radio repair video. I started watching the video in bed and I fell asleep halfway through it. Then I started hearing "This is only a test, this is only a test" in the background of an absurd dream where some mechanical birds were trying to fly into my house. Then I woke up and heard you say "This is what nightmares are made out of right there" It felt so weird at the time. I watched the video in its entirety the next day and sure enough the "Today is a great day, testing testing" lady was really there 😁

[@KC4RAE]

It's one of many traveler's information stations ('TIS') in that area. TIS is limited to 10 watts and found in metro areas and sometimes, multiple ones sync'd to cover a larger area.

[@ShyMagpie]

@@KC4RAE Thank you. I guess what's on the lower end of the short wave dial of that radio is now part of the expanded AM/MW band?

[@KC4RAE]

@@ShyMagpie It's still considered medium wave. Technically speaking, the upper limit of medium wave is 3000 kHz, but some of it is considered part of shortwave bands regardless. That could be in part for ease of distinction between medium wave and international use of spectrum above 1800 kHz.

some great radios fixed by the right person. I was looking to purchase a zenith 600 transoceanic last year, but the person in the bay area selling wouldn't tell me if you were the person that recapped it. they simply said it was recapped.

Wait, are the eveready carbons supposed to be gone by now? Here they're still available, and are probably the most inexpensive of all.

[@tarstarkusz]

The Panasonic carbon cells are pretty good and readily available and cheap. They are pretty well made. WAY better than dollar tree. You can literally crush a dollar tree battery with your fingers. I have a local supermarket that cells Kodak carbon-zinc D cell 2 pack for about a dollar. They are great. 8000mah according to the data sheet.

[@Sys-Edit0r-1995]

I like to call them "explodacells" because I've had two pairs of AAA's blowup in my headphones while I was wearing and using them. And a third time when I wasn't!

[@VectraQS]

I have seen two *very* corroded Eveready cat cells before, however I also have two pristine (but dead) ones too. FWIW one set was stored in climate controlled closets for 40 years, the other set was in a house with no central air. Interestingly enough, both sets were in cameras, one in a Kodak Hawkeye FlashFun II and the other set from a Polaroid Swinger.

What was that monotonous drone that I could hear while you were tapping round the Panasonic? Can that be fixed too?

Drift was cured by putting a tiny amount of silicon paste on the dial tuning cord to eliminate back lash. Still have a broken carbon core in a small tuning coil so AM only works at the top end of the band. SW bands work great this thing is hot as can be in sensitivity and a super low noise floor that modern digital radios can't beat.

The multi-band National Panasonic radio appears to be newer than the Sony, as the former does not have the CONELRAD emergency frequency markings on the MW dial. Obviously, both came off their respective manufacturers' assembly lines during the dark days of the Cold War, though. It's also noted that frequencies are denominated in megacycles (MC) instead of MegaHertz (MHz).

I’ve pretty much gone to rechargeable batteries. While technically they can leak, I’ve not had one go yet in the two decades since I began using them. I have have nearly a hundred of them. They don’t provide as much umph as alkaline batteries, but I got tired of both the cost of new throw-away batteries and their tendency to leak in equipment where they are needed to provide backup and don’t get replaced but maybe once every year or two.
