"It's nice to hear 1A2 still exists other than my house."

I just finished a short internship at KMOX (probably the biggest AM station in the country). Of course, they use 1A2 on air, as lots of stations do. But they also still use a seperate 1a2 system throughout their entire newsroom for everyday phone use.

Ahhhhh.... The good ole' days!!!

It sounds like there's still a few 1A2s out there. In fact about 20 years ago I worked at a AM/FM station (AM just a daytimer 500 watts), they had an electronic TIE system with no delay for phone calls on the air. I remember I had the opportunity to interview 2 members of the rock band Def Leppard & I took a few phone calls from listeners. One said "Wow Def Leppard..holy #&%T!". Loud & clear over the air.

Ouch...bet that cost the station. Or did it? Stations didn't usually have to worry about that sort of stuff back then. Now with Janet Jackson's superbowl show and Howard Stern and the like, I don't think you'll find a station that doesn't use a delay when taking calls.

Hows this for old.. KZSU-FM (Stanford Univ) has a WE 711B SxS PBX still in service, as well as a 1A2 system..
Outside plant from the studios to the transmitter, as well to to about a dozen remote sites on campus.

Now that's interesting. I was wondering if there's still any step PBXs out there. Never worked on one but remember seeing what appeared to be a large round motors that I think were dial tone generators. If no registers were in use and you picked up a line you'd actually hear the dial tone rev up to it's standard tone because the motor needed to start. I'd love to see something like the 711B in a museum.

Stanford, the Harvard of the west?

And I've never used a phone behind a switch that wasn't digital (i.e not elctromechanical)!

It' been awhile since I've been to this message board, but actually no one got in trouble for the slip of the four letter word on the air. The other day on some TV show, wish I remember which, I saw one of those KSU-less keyets. There were four keys total, I think 2 lines and each line had an associated hold key. I haven't seen those in well over 20 years. The TV show was not an old re-run. I wonder if it was mixed in with other phone props.

An example of why I like 1A2, at least for home use is I just made a circuit that mutes the nearby page speaker when the kitchen phone goes off hook on the intercom line. It's a very basic circuit using the series line relay from a K400E line card and another relay. The reason for the circuit is I'd get feedback when paging using the speakerphone. There are of course disadvantages, behind the living room couch is an IDF!. It's just a 25pair block feeding 2 phones and jacks for on-line dial-up

I've got plenty of 66E3 blocks to help keep your 1A2 ship-shape for sale!!!!!! CHEEP.
