What are you Listening To Right Now? - and more

Always wild but it's true—fast changing (hopping) frequencies makes a lot more channels available and makes it harder to decipher. Claude Shannon's papers are seminal to most of our current technology.

"In 1942, actress Hedy Lamarr and composer George Antheil received U.S. patent 2,292,387 for their "Secret Communications System",[9][10] an early version of frequency hopping using a piano-roll to switch among 88 frequencies to make radio-guided torpedoes harder for enemies to detect or jam. They then donated the patent to the U.S. Navy."[11]


Probably saved 1000’s of sailors lives. They should have gotten a medal
 
Looks great. Plenty of stores around here as well. Problem is prices have gotten stupid
Went into a record store recently, and it was all automatically $35 and up. New Arrivals had the usual Elvis Costello hit albums at 25$ with ringwear, and all 45s were priced at 10$ per. Not "hot" or oldies 45s, either. I saw at least 2 copies of 867-5309 priced at 10 bucks each in generic Columbia CBS sleeves.

While Discogs is also pricey as hell, I find that you can pinpoint honest sellers where it is worth it. Some guys actually grade fairly and ship securely there.
 
She sure did!:thumbsup:

Awesome! I very much like how you curated that.

Agree. 60% of my buys are DISCOGS. I have about 10 sellers I use generally speaking. 10% are Bartertown buyers
AK’ers take care of their albums and you won’t get screwed. The rest are my favorite store that nowadays I just go for the fun of it
No purchase in mind. I usually get something but it’s the visit more than anything
Times change I guess
 
No, I’ve been banned before for shooting my mouth off. I’ve learned to maintain. Away from AK, Not so much

I was posting a lot on Political Chat until it became boring sometime back in 2011. A lot of good people there from both sides and well written arguments IMHO. For me, it became too time consuming to write a cogent position regardless of the politics. It was fun and some of those folks are right here on this great thread. @bobabode, @finnbow, @merrylander
