WNTD 950 Left both transmitters on all night again

I wonder if they can be fined for that.

It's generally the same as when a station has a synchronous repeater... the area where both signals are about the same strength, there is flutter caused by slight time differences in the arrival of the audio. It can be minimal, or quite pronounced depending on how well synched they are; since the 950 sites were not designed to be synchronized I'd imagine that a significant area had really annoying unlistenable reception.
At my location, the station is pretty unlistenable with both transmitters on the air. There is a noticeable delay between the audio signals from each one. I would estimate the carrier frequencies to be within about 1 or 2 Hz of each other.
I understand that one of the transmitters is omnidirectional (the one normally used in the daytime), so the station is probably interfering with others on that frequency at night.

This used to happen a bit when they were WJPC, as rap radio. This was when their night signal was designed to replicate the day signal.
They had this pattern during the whole WJPC/WLNR and J106 days. They had a great signal which except for other stations bleeding at night was identical to the daytime coverage. It was 5,500 ERP, with the same six towers in Burnham.
A few months into the rap format they altered the pattern to either acommidate WAUR 930 which upped their nite signal to 4.2 kW from 2.2 kW, or 950 in Detroit to go 50kW at night.
I have still not been able to find an answer for this, the power was lowered and I could hardly receive them at night in places like Palos and Tinley, were as before they came in well in Romeoville at night, not much different than the day.
At that point you could not even pick them out of noise at night at Romeoville. This pattern remained the same after they were sold twice in the 106 Jamz period.
When the station was sold to One On One(Sporting News Radio), they were off the air a couple of nights and came back with a stronger signal, not even close to the original yet back at 5kW. People have said it was natural change or the noise floor, it was not though, this did not happen over time, they changes were marked and noticable. If anyone knows the real details please let me know.
As for the night and day being on at the same time, it does cause an echo effect in my area. I think they change towers manually. Some days there is a delay from when they change from one site to the other. Usually it is only a couple of seconds, it has been more like 20 minutes once in a while.
They also switch some nights and mornings with 5 or 10 seconds of overlap, when both are on, you hear the distortion when done like this.
They also used to be on a different time clock than other AM stations. They would change pattern 1 hour before Chicago sunrise and one hour before sunset. So in July they switched to night at 7:30 instead of 8:30. This went on for years, so it was by design.
I never understood why they gave up their rare signal, which boosted power at night as opposed to lowering it. This station was able to cover the whole area both day and night, unlike any other small AM.
They are at 5kW, it is not the same though.
Another thing they did a lot was forget to change at all. They would leave the day tower on all night or leave the night towers on all day.
How much would the Omni daytime signal affect other stations at night? Their night signal is so poor now compared to when they were "The Smooth Touch"
