Former airplane owner: Heard your comment about leaded avgas. After more than two decades we recently got an unleaded 100 octane gas approved. The impact on your aircraft noise is going to depend on how much more expensive it is than the leaded stuff.

[@tucker934]

@@PapiDoesIt that’s my concern, the lead in it is to provide protection a cushion, and I think there’s more too it I’m no plan expert by no means but I know on those types of aircraft the air fuel ratio is pretty critical, but what I’m not sure of is if the mixture is the same as that of a vehicle which is 14.5 if I recall correctly. If it isn’t 14.5 and let’s say they are running leaner than that that’s a lot of heat!

[@oldradiotvsc9836]

Cool!! I have built the AES battery eliminator kit back in the late '80s or so, and have used it to power several types of battery tube radios, including an Atwater Kent 20C. It is a great kit, I still have it but need to change the LM317 regulator for the "A" supply because one of the leads broke off it while moving! I always think these old personal portable tube radios are cool, especially "subminiature" ones, but also the regular miniature tube ones as well as larger earlier "suitcase" type with the larger octal tubes!

[@oldradiotvsc9836]

Oh! Also, I have that same "Harpers" radio, which the name plate had come off of mine so now I have an idea of the brand name now! Japanese, and mine has unfortunately a big piece of plastic missing from the back cover.

Chinese counterfeit parts are a plague. I bought many Toshiba and Motorola audio output transistors online. All were counterfeit. Never again. I since bought them only at well known distributors. They were supposed to be 200W RMS but the die inside the plastic casings were as small and even smaller than the one you'll find in a BD 139/ TO-220 types. There's also many counterfeit capacitors as well on the market. When the price is too good to be true, that's because it isn't. I'm glad you address it! Those are shyte.. Edit: English isn't my language.

[@rectify2003]

I Love people who work on old technology - It brings back so many memories I became a service engineer just as valves were leaving. Where I lived not far from the Air Force Base, when we watched American movies, like Star Trek and Time Tunnel, we turned the TV Volume down, and tuned to FM on the Radio to get it in English

[@javierbiaggi3072]

You're incredible! So knowledgeable on radios and tvs that there's almost anything so broken or destroyed you can find a way to make it come back alive. And not only that you make them better. I love your archeological trips finding pieces and bring them alive. You should be the curator of a Radio- TV Museum.

[@eDoc2020]

On the first radio you connected the negative of the B supply to the ground of the A supply. Assuming the standard circuit this is improper. The B- input goes through a resistor which provides cathode bias for the output tube.

[@sonsofthunder915]

You have a dead personal radio ? "Don't worry, you've got this".

[@johnwsimpson3153]

Interesting old radios. According to Radio Museum, the GE was made in 1954 and the Harpers was made in 1960. Their time was short. I got my first portable radio in the late 50s, and it had transistors. Same 9 volt battery that is still commonly used. Tubes were still used in table radios into the 60s, because I bought one in 1963 when I went off to college.

[@chriscimino7854]

Hello Shango I want to share my experience with an eight track player I just repaired. I know it has no relavence to this video but its about an old audio amplifier that has crackling sound in one channel. At first I thought it was a bad germanium transistor but before I changed it I shorted the input leads going to the head on that channel and the crackling stopped. This amplifier uses PNP germanium transistors and instead of using ground for the head coax wire shield it uses the negative hot wire which is about twelve volts potential from ground. The head case is ground and what was happening was there was moisture on the phenolic insulator that holds the head leads and making high resistance leakage on the sensitive input lead. I took my heat gun and boiled away and dried out the insulator and no more crackling

[@jeffreyhickman3871]

That’s a great collection of radios. I hope 🤞 they all have a dial cord diagram in the back of them. Battery tube type radios seem very rare to come by at any yard sales. I’d probably run 🏃‍♀️ these on a 12 volt car battery, since it would seem the most sustainable source. Your friend, Jeff.

[@joeblow8593]

I thought the Caltrans testing lady left the air, unless this was recorded a few months ago, But if this is newer video, then can I suggest doing a transmitter hunt for the source of the Caltrans testing lady. I'll bet the transmitter is on the side of the road right near a major road or interstate. The antenna is usually fiberglass white and a bit taller than a Solarcon A-99 CB antenna

[@monkeyboy4746]

I have a clear memory of B batteries, when I was a little kid in the 60's, I ran my little fingers across the battery poles of a B battery I saw for sale in a department store. It burned the memory into my brain.

IIRC the 3V4 and 3S4 are the same electrically, but different pinout's. The 1u4 is the more common IF tube, but some sets used the remote cuttoff 1T4.

[@Crosley-1520]

3V4 and 3Q4, actually. The 3S4 has slightly lower specs (e.g. 67.5V g2 max, vs 100V for 3Q4/3V4), 3S4 and 3Q4 share the same pinout.

[@oldradiotvsc9836]

@@Crosley-1520 Thanks for pointing this out, I often wondered if there was any difference besides pinouts. Makes sense that the Harpers radio uses a 3S4 to conserve some power as well as run more ideally on a 67.5V battery rather than a 75 or 90V B battery.

My handle's pleatherette handle is peeling, but the case is not chewed. It listens to a 1 kw daytimer that plays oldies and local ads. At night, I like to open the back and barely see a bit of bulb glow. I show it to youngsters, and they don't get it.

If those tubes ever have to be replaced, look into 1Ж24Б and similar "rod" tubes, over here these military surplus tubes are often used to substitute the much more expensive American tubes which were imported back in the commie era for use in the locally produced portable tube radios. They also should be more efficient than the original tubes, at least in the RF portion of the circuit. Said tube is an RF pentode drawing just 13mA at 1.2V.

It would be interesting to know what the test station is all about. I imagine it would be government run or endorced as it would cost a fair bit of money to keep it powered up and running. The selectivity on the GE seems reasonably good, maybe a little alignment will help the sensitivity, but for an unrestored portable it seems to work ok. I guess people wouldn't use a battery radio for DXing really. With the little Japanese Harpers radio, it could be the person that sent it to you put the cardboard in place to help hold the tubes during transport. It likely didn't have cardboard from the factory.

@@acoustic61 AFAIK, there isn't even any (serious) debate about that. The lead does not become airborne. The fumes you see while soldering come from the rosin and from contamination. Shango has been told this time and time again, and yet, he choses to repeat this type of statement all the time anyways. Which in itself is not surprising, considering where he's from, even though he's definitely one of the least mental inhabitants of that dismal place. Of course, you wouldn't want that stuff in your water pipes, where it might get eroded and would contaminate the water downstream. Even though I'm not sure if I'd even worry about that, as I would think the limescale buildup quickly starts to inhibit the erosion process after the pipe is installed - but I'm no expert on that. I would say that, all be it it's kind of a cliché statement by now, people are way too soft and afraid of everything nowadays.

[@MrJDNJ]

Wondering if anyone can talk about older radios that have TV channel bands. I just got an old Sears unit (Model 800 272400) with TV1 and TV2 bands (2-6) (7-13). Of course TV is all digital now, but on TV1 there's a bunch of what seem to be FM stations, coming in clearer (super clear, no static,) than the regular FM band. The station is 91.5 FM, but the dial is up around 100 FM and just above channel 4 on TV1. Paid $1 for the unit. Had to spray all the switches, but it's a pleasant surprise that it's working so well.....just curious if the TV band is a more accurate tuning subset of FM??

[@n2n8sda]

no the tv bands are just regular FM at frequencies outside the radio spectrum (88-108). The FM audio for analog TV 1-6 was between 48-79mhz if memory is correct and for the higher channels it was around 180-220mhz. most likely the radio is way out of alignment or the band selection switch isn't working properly if you are picking up a station broadcast on 91mhz on the TV1 band, picking up a harmonic is possible but it shouldn't sound better than the correct frequency. Also FM usually does sound good with no crackles if your radio is in good order and the signal is good.

So as I understand it, this is basically only a test then!?

Probably these sets were used when families went on outdoor outings.

'You've got this!"...yep. That and that idiotic response particularly by the Millennials: "Perfect!" Perfect...everything's just "perfect".

Which radio station is that at 1600 kHz, with only a female voice?

[@azariayehezkel9064]

I wonder if that "testing" radio station is some weird government thing.

How do you make a 1v power suppy?

Wow did they really use cardboard in that Harpers? That was probably pretty cheap.

General aviation is so slow to change. To get a new engine certified means going through a million hoops. There really only has been one new engine type successfully released in the last 70 years (Rotax). The Continentals and Lycoming are pretty much the standard and were designed for leaded fuel three quarters a century ago. Even cylinder head upgrades have unknown consequences on reliability - they say..They need a rocket somewhere.
