AM Frequency of the Week: 800

[Ai4i]

I knew I would not hear it,
but I could fantasize about it!

I heard them last night; I assume they were on their west-northwest pattern.
There are a LOT more stations on 800 now than there were "back then".
They need to figure a way to get on 1710.

Right now, Raul and Arnie Coro (who I assume is in charge of such things) have 800 pretty clear. I'm assuming Central Mexico is a bonus.

Holy cow, that would be some massive skywave. Not like they would need the groundwave coverage considering their location (and it might be decent anyway with the salt water despite the high frequency).

Actually, no bovine deities need to be summoned.
Saltwater groundwave propagation is MUCH less frequency dependent
than most landlubbers would imagine.

I would imagine a lot of those 50s cars that you still see in Cuba have original equipment radios that wouldn't get 1710?

I'd doubt that. Those radios used American tubes, and they were not, for the most part not compatible with the Russian tubes that were all that was available in Cuba. So they were likely replaced with other radios when the tubes failed and replacements were not available.

I remember touching an AM car radio telescopic whip antenna and getting a "SHOCK".
It must have used a switching type power supply for the plate voltage.
That was during my very early formative years.

Actually, they used an early form of switching supply using a vibrator, which switched the power to a transformer rapidly on and off, to produce the 200 volts or so needed by the tubes. Later on, some tubes were developed that could run on 12 volts, but by that time transistors were taking over.
