How is it not dangerous for you to stand right next to it?

37:40 feels like a Fallout game; even Emergency Rations

SUPER Dad

I use a Tecsun 880 in my Tesla to tune into AM radio without problems

Yes. Cable "Management".

What do you mean "in the West"? Is there an older one in the Eastern hemisphere?

Coming from an enterprise environment, if you leave bad batteries in older APC units too long (like months) you will damage the UPS.

NIST Calibration

A friend and I climbed halfway up an AM tower in our early teens. No idea what the power rating was. Obviously never got zapped, but we attracted cars passing on the nearby highway and hurried down. It was long before cell phones so we left before cops got there, if they did.

Analog life!

I may be late seeing as this video was released 8 months ago, but don't touch that tower.

Too bad they did not add a passthrough hdmi port... the rtc battery is a fantastic feature, you could potentially set alarms to turn off or on the computer at a given date no need to have ntp set up

Congrats to both of you. Really enjoy your UA-cam channel; keep'em coming. '73 de Bob N7ISU.

It turns the frogs gay, too.

Potomac is pronounced puhTOWmik. It’s the river that runs through Washington DC.

What about FM? I don't mess with that newfangled sorcery.

I had a hole blasted in my thumb through a glove from a 1kw transmitter, the owner shut the tower down (so he thought, got sidetracked by our conversation). When I got outside to the tower I thought I could still "feel" the energy, and instead of walking 200 ft back to the headend or walking the same distance to the truck for the voltage indicator, just to make sure (With my gear on in 100deg heat after all I saw him open the panel on the transmitter where the breaker is) I decided to skim the ring with my thumb.. not smart.

It becomes even more charming to hear the discussion of this great old gear when the guest has a regularly Mr.Roger's-sounding voice!

What does it do?

hi I'm a retired engineer i helped design auto seat control . we were required to meet very strict EM interference. i know that most Chinese equipment is imported with out any FCC or UL testing even if there labeling may indicates it

For a radio geek, this is as close to x-rated youtube content as you can get ♥

9:58 So they have 6 of them....i'm trying to convince myself to afford ONE...😯

Wait, why are there so many boxes of MRE’s?

WION 1430 (((AM Stereo))) The Music You Know - The Information You Need 🥰 Also available on FM92.7 & FM100.3 - Streaming Full Frequency AM Stereo to the World from a Potomac Instruments SMR-11 Broadcast Receiver in the studio. I'm not in the USA...But WION is the only station I listen to. Their analogue AM Stereo sounds incredible! This station really knows how it 'should' be done!

I live in Sweden where there have not been any AM transmission except for one station aimed at listeners in other countrys, in a very long time. We have our emergency broadcasts on the FM band, and with RDS. Even so, I am a ham-radio operator, and I used to use my radio mobile, in the car, it worked great on older cars and on my last diesel, but stopping at a red light next to a modern car more or less wipes out anything on AM. We also had some "information-billboards" on some highways that were so bad they got banned close to airports because they interfered with AM on the airband. I think (sadly) the time of AM och HF-bands are close to over.

ELEPHANT in the room: Melon Husk decided to save $80 for a few capacitors and an antenna. No other manufacturer I'm aware of has an EMF issue. He is just a cheap skate scumbag who manufactures rubbish quality cars, who doesn't care about anyone except his tech bro fan club that are too young to know what AM is, devaluing America's reputation for quality, the world over. 🚬

1) That is not transmitting on Channel 5. It transmits on channel 35, which is situated between 596 and 602 MHz, not "599 MHz". 2) That 77Mbit/s link on the STL/TSL includes a majority of IP data which has nothing to do with what is fed to the transmitter, which for ATSC runs at 19.392658Mbit/s The rest of that link is available for the engineers to watch boring UA-cam videos. 3) The "lines" are not "streamed". The picture is an MPEG(2) compressed transport stream which sends data containing the whole picture(s) (from each main/sub channel) at one time. We no longer transmit line-based video. If one were to break down this data to a more component level, we're actually sending big blocks of the 29.97/59.94 frames per second video. That's why when you see poor video reception, you get huge blocks of video that tear, delay, distort, and generally look terrible - not individual lines. 4) Too bad for the poor engineers who have to service that GatesAir. They should have purchased a Rohde & Schwarz. The R&S is on such a higher level of "cool" and technical superiority that comparatively, this GatesAir is a Pentium III and the latest R&S THU is a 12th generation i9. I guess Mr. Carcopo just needed to have things to do though... which is good for him. 5) Those things hanging in the ceiling are not just waveguide. It's technically a hybrid combiner / magic-tee. this allows the transmitter to be switched so that one side of that transmitter can be dedicated fully to the antenna without losing 50% of the active transmitter to heat a dummy load, which would result in only 25% of the normal power reaching the antenna instead of 50% using a magic tee system like this. 6) Don't let OSHA see you opening that transfer switch without wearing arc flash gear. Surely you two donned that arc flash gear before opening that door ;) 7) Those "weird bowties" on the tower are the original channel 5 antenna. It is actually called a "batwing" antenna, and this one operates on the actual channel 5 (76-82 MHz).

And still nothing to watch on TEE VEE. I've been a decimated TV antenna for decades but watch very little broad television anymore. Maybe one or two hours of OTA TV a month, if that! The broadcast network are essentially dead. Local news and programming is beyond awful. Even PBS has fallen way, way down in quality programming. THIS is the result of consolidation of television stations into the hands of a few corporate owners such as Sinclair, Nextstar and others. Just like FM and AM both radio bands are dead to me.

I have not long retired from this work & I still miss it. After 55 years I have to find another hobby if I can, going to be hard to beat ! Excellent video guys, Cheers !

I get some signal in croatia with my best modified radio

Just the accountants and CEOs trying to squeeze the turnip ..., er, maximize shareholder value, with the customers and citizens be damned.

How many engineers were in on designing this

*"If I touch this tower, I die"* -- If you touch my car you die!🤪

Of course, propaganda has moved on to other formats nowadays.

Calibration stickers and docs only means something if calibration cycles are maintained according to the manufacturers specs. Pass the required calibration cycle date and the calibration is no longer valid. It sounds like dad it trying really hard to sell it.. Hyping it up to get the price up. Regarding something having a particular collectors value, it's value is only what someone is willing to pay for it at any given moment.

Cool collectible radio, however I can do the same thing with my cheap AM pocket radio by turning it. I know where the null is, so I know where the transmitter is and my signal strength meter is my ears. I do really like that tunable external loop antenna, more than the radio. I might build one of my own. Have been meaning to do it some day. You can also enhance reception of a radio by putting it near the loop even without a connection.

Knowing that the cost of the AM/FM radio components was trivial, I realized that the cost was in making the electric motors in the car low-mission. AM is very sensitive to local electronic fields (like those generated by coils or motors). A famous use of this was in the early days of hobbyist computing, where someone demonstrated a "music" program using a MITS Altair 8800 computer and an AM radio. Just by manipulating the computer program paths, they could play recognizable tunes on a nearby AM radio. How interesting that demonstration becomes today as we move into the EV era!

You and your dad are awesome, love the bantering, terrific!

When I worked Telstra broadcasting directorate here in Australia one of our crews lost the calibration dipole that came with one of our Potomac UHF FIM’s whilst doing a survey . The headache and cost of getting a replacement including sending the unit back to the states to get a replacement calibrated to it. Fortunately a farmer found the antenna and managed to get it back to us so the company paid for a brand new TV antenna installation at his house as a reward.

thanks for making this vid

My first car had no radio, so I guess it would have been illegal in the US. Anyway, you want people to have access to AM radio everywhere ? Just make a law for AM to be mandatory in all mobile phones, it makes more sense what having it in cars.

Very interesting. I grew up not too far from that tower, and always wanted to know what it was all about.

At 14:05 - So much to understand there. Just recently some car manufacturers were wanting to get rid of AM radio reception in their vehicles. Not only that, the reception of that signal in a major disaster would be fueled by diesel as this video shows. Unpack and get all that! Who is calling the shots here?

How many dB of insertation loss does one elbow cause?

7:22 austin ring transformer Aren t there many magnetic losses in that open air transformer wouldn t you lose half of the power before energizing the antenna? a radio amateur asking
