WRFG 89.3

What is going on with WRFG? They've had low distorted audio for quite some time. Sounds like bad capacitors in their audio chain. Now, I realize this is a Donation Station but do they not listen to their own signal?
Their transmitter is at the Briarcliff plant and their studio is at L5P. Not sure if they have a phone line or 900 MHz STL but it should be a straight shot of 2 miles for them.
Where's Alleo? Got to get him on the case!
 
Some audio sounds either heavy left or right...or out of phase on WRFG. I believe they are using a T1 for the STL.
 
Listened on a mono radio and it was almost totally cancelled out. Yep, one channel out of phase. Its 3.5 miles from the Briarcliff plant. That's a short run for a T1 circuit. Most likely 8KHz dry pair for an STL. Probably cheaper than a T1 also. But of course it could get reversed phased anywhere.
I remember going down there and eating at the Vortex.
Where is Alleo? Did he get banned or is he down with the Covid. Maybe his keyboard finally gave up.

Where in a stereo FM airchain does a discrete stereo signal from the source get converted to multiplex (sum and difference)?

That takes place in the stereo generator, which is part of the initial generation of the FM signal in the exciter. Way-back-when in the 60's when stereo was new, the stereo generator "plugged in" or merged with the exciter as a separate unit. Now, fully integrated transmitters have all the elements integrated... even the HD and RDS functions.

Think of it like a newer car which has an electronic system that shares components with modules for the radio, maps, diagnostics, etc in a single system. The individual sections may be on separate modules, or may be all on one board.
 
This station is an embarrassment to the art of broadcasting. Even the pirates sound better! I don't think it would be a good idea to loan them a BRIC. You'd probably never get it back. That L5P area they're in has got be be a high rent area for office space.
Orban used to have a phase chaser. It seemed to work pretty well at the station I was at as I recall. The station is probably an engineering nightmare with masking tape for connections etc.
Input to legacy exciters is left and right.
Too bad about alleo.

L5P was probably cheap back in the day, but not now. They could stand to move to save money today.

And thank you David and kf4rca for the technical info.
 
I retired from ATT 11 years ago. During the Southern Bell/BellSouth days, I worked on T1 and all broadcast lines. The distance from L5Pts and down Briarcliff is a short drive. However, that T1 line from 5Pts goes to 51Ivy St, the main ATT swithing center. From there, it jumps on a carrier to the N Druid Hills Central Office, corner of N Druid Hills and Briarcliff, right behind the Dunkin'.
From there, to site. No excuse for the bad audio, though.
 
You mean N. Druid Hills & LaVista. Some of their programs sounded OK and some sounded reverse-phased.
It was about time they got it straightened out. Most likely they had an engineer/technician but he never got re-imbursed for out of pocket expenses and he just said to hell with it.
Did it go to Ivy Street so you could cut them off when they didn't pay the bill?
Do they still have any A2A stuff coming out of there? Thanks.

Yes, Druid and LaVista, behind Dunkin Donuts. No idea what is coming out of there today. I worked there in the early 70-s...retired in 2010. But once ATT took over from Bellsouth, things changed for the worse and I transferred to a different job, after being moved to the HUGE center in Conyers on Salem Rd. There, it was one of 5 broadcast centers (Chicago, St Louis, LA, Conyers, and I believe, Richmond, VA) att had at the time, radio/TV came through there from NY and west coast before feeding to the Southeast stations. But, they were fun days.
 
I remember going to 51 Ivy for an SBE meeting and was impressed by the big Remind-O-Clock.
Bell has some sophisticated terminating modules out there these days. Microprocessors in them. They can set up EQ on a line from the CO downtown without having to visit the site.
We had A2A at CNN when I was there. I remember the Telemet clamper in the rack. It was used for the Washington feed. NYC was patched thru in Washington. It was cheaper than satellite at the time especially for 24/7. I remember sat time used to be $500 an hour. It costs a lot to launch a satellite. AT&T gave us a better deal. And you didn't have to deal with all the delay problems that came with satellite.
I think TV2 and TV11 also had A2A. Its hard to get a MW shot thru downtown Atlanta with all the tall buildings, etc.
