While I was taking a break from the usual post weekend home repair :( here at the shelter, listening to WMBG 740 in Williamsburg due to WJOI is no longer a pleasant listen because they blew the tower " rather than it fall down".
I moved the tune of the Panasonic only up a little because I noticed some spatter. It's Jones talking about power pills you need to take on the empire and protect and purge you of the heavy metals. This radio has no shortwave capability
Wow , I didn't know he was on AM. Then call letters WWCR.
It ran for about 5 mins and drastically increased with my hand near the telescopic.
I managed to get a cell phone vid .
I've heard shortwave come blasting through on a crystal set that lacked any ability to reject strong sigs and just blew through the magnetic fields in the coils.
But the Panasonics are high quality radios that would permit no such thing.
When it faded a religious station came up , ( WBMD?) confirmed it was 750 kHz ish.
12160 KHZ divided by 16 is 760
A nearby DX 380 could not hear it but I managed to put WWCR at 750 - 760ish based on the 750 religious station match and readout of the DX 380
So ..?

I had a Technics receiver in the mid-70's that would pick up SW if I hooked to the TV antenna. I was hoping for FM dx.

Alex Jones is on some AM stations. He was on several I'd hear during the evening up until at least a couple years ago.
The fact that the radio in the video is a Panasonic wouldn't necessarily make it spur-proof. It's probably single conversion, as many other AM/FM's are.
Or you might have picked him up on a station from Florida on 790 (according to his affiliate list -- no idea how current his list is), if you heard it at night.
Either way -- interesting catch. I've never heard SW on an AM/FM radio on the AM band, except a long time ago, a friend's home stereo would pick up Radio Moscow sometimes, very high up in the AM band -- it was an obvious image or spur (mixing product of some type).

Hmmm, this is an interesting one. The fact that the DX380 did not hear it indicates that it is some kind of a mixing product
developed in the Panasonic. Have heard SW stations on an AM radio before but never as loud as what you heard.
Let me give this some more thought...
-
Looks like there are a couple of AM affiliate stations in VA... WNTW AM 820 and WKGM AM 940, both @ 10 kw.
Do you live near either of those ? Also, what type of antenna were you using on both radios ?
Do you live near any AM station ?

Most of those high end tube receiver/amp combos of the 60's/70's were set up for those newfangled FM classical and hippy stations, they were set up to be broadbanded. If you tried to attach an AM antenna in a crowded market it turned into a stew. I used to get Radio Australia's SW service on 1240 kHz when the greyline was right. As Melbourne was about 12 hrs ahead of us, I'd let it go to screw with people. You think they would have noticed the difference in accents?

I'm between 2 AM stations that carrier Alex Jones, one in Athens, OH, and another somewhere in Virginia. No one carriers him where I am, (Go figure...). There are a lot of Part #15 and FM pirate stations that carry him as well. In the mid-90's, I remember hearing Alex Jones on Brockport, NY's WASB. As far as the IMD overload from WWCR? There's a POS CB preamp that was lousy about IMD, where SW stations can be heard on CB's. Remember the American super splatter WEWN, and Glen Hauser puts it? I use to hear that with this preamp.

Thanks for the postulates so far... 790 here is WNIS , i must be in the beam you can hear it on a broken radio. I will never post dx on 790 8). The reception was on the internal MW ferrite and telescopic retracted. I'm positive it was WWCR , the standard id clip they use. I can rule out any part 15 relay in my neighborhood - i get questions about " the wire in your yard " and when i answer you can tell by their faces they still dont understand.
Ive never heard any of the Jones affiliates at night even . The video and reception was mid afternoon.
Another thing i noticed was the audio seemed crispy and not really stable , and also very high hand capacity near the telescopic up to 3 inches away not normally noticed , but makes sense -a skywave that the telescopic is better at. It definitely was confined to 750-760 and tunable. Mathematically near a divisor of 12160 , but maybe a coincidence
i too believe it was a strong possibility of a fault in the radio but by the time i heard the id it was nearly gone. this radio was a store sound system for a couple of years 18 hrs a day without any hiccups.
It seems though it would take an unusually strong signal for this condition, however.
-
If Bill Hicks was coming in well and suddenly gone, that might be from a legit amer carrying Hicks show disinfowars that switched to low power and/or an array change.
-
Again, the key here is that the DX380 did not hear it. This indicates some kind of product developed in the Panasonic
mixing stage probably caused by overload which drives the stage into non-linear operation.
Since no external antenna was involved, it can be considered internal mixing.
Since it was tunable, you can rule out IF feedthrough or audio stage rectification.
Problem is that with internal mixing there is an almost limitless combination of frequencies
that can cause what you heard so figuring out the source may be impossible.
-
Sounds good , youre right about the the key points and also any further theory. Just seemed in line with other weird around here recently , trying to figure out if its just me or what.
Thanks!

It's not you... you heard what you heard... it's the radio.
All part of what makes radio interesting. :)

If people would ignore Jones he would go away. Problem solved.

My 1982 Sherwood receiver (still works) would regularly pick up RVI (Belgium).
-
Were the '82's the last of the all tube Sherwoods?
-
I'm not sure.
-
'82 was about the end of hollow state receivers and amps for home audiophiles. I wish I had dime for every time I heard guys in the tube days shout out at morning break, "Oh $h!t, I left my amp on this morning!" and sweating it until lunch when he could fly out of there, get home, turn it off and get back to the office.
I liked those Sherwoods, good stuff.
My cousin bought a Harman-Kardon in Vietnam, it still works. It has an SW section to it. I never got to check it out, no one is allowed to touch it but him.
-
Sherwood receiver/Hitachi tape deck/ Technics turntable (all still operating) and long gone speakers all for $630 in 1982.

That they (tube equipment) will suddenly burst into flames and burn down the house is a kind of funny mythology as far as i can tell. If thats what they were paranoid about.
Never heard of a radio or amp actually flaming . A capacitor might short , but they will just pop and thats it. Chances of anything going wrong suddenly with something that modern probably very low
I have a little piece of crap Philco chassis that stays on for days or sometimes just 12 -14 hours a day, just to see if anything happens. One original 12BE6 failed last year that by the looks of the plastic cabinet i threw away - had 1000s of hrs before my experiment , other than that no drama.
-
If I want to double the lectric bill I just leave the R388 and R390A on all day. At least when it's cold they add some heat to the room.
-
I never heard much about fires, just blown tubes if they got too hot. There wasn't much air flow in those things
The tubes and other parts were notorious for going "poof" in those things if you left them on too long, Dave, especially the 100 watters. That meant a trip to Stereo World (pick a name) where one or more of your fried parts was going to be definitely OOS or no longer made, throw in the Tech's labor cost who "knew of a way to get it to work", a little for the salesman who originally sold you the system and multiply it by three. Then they'd unlock the doors and let you out if you gave them cash up front.
Used cars salesmen were a more honest bunch than the guys who sold sound systems
