Awesome Groundwaves 10000 Watts Or Less

What time of year was that?

Pre-Hurricane season... March (of 1980). I didn't want to take a big storm in a 32 foot sailboat with just two of us on board.

The reason I asked is because it would determine to what extent reception of WBZ was skywave or groundwave.

If it was the middle of winter, it could easily be skywave but getting into March and considering the lower latitude, a daytime skywave from Boston seems unlikely, especially a consistent one, since you said WBZ was there all the time.

I've always wondered about the "overlap" of WAPI in Birmingham and WFLI in Chattanooga which are on the same frequency (1070), but only 143 miles apart. I know there are local freqs. (1340) that have extremely short spacing, and WFLI is directional, but both stations are 50kw in the daytime.

1. Anyone ever been in NE Alabama to hear any conflict on 1070?
2. Are there any other two regional AM stations that have shorter spacing than these two?

This goes back a long way, but at one time there were supposedly three stations on 1550 in Alabama. Only one, WLOR Huntsville (formerly WAAY), remains on the air. It has 50,000 watts daytime now, after running 5,000 for much of its existence. WMOO Mobile operated for years with 50,000 watts day, going off the air in the mid-80's, and once there was also a 50,000 watt daytimer in Birmingham. That's according to listings from that era, anyway, showing the station (WBHM) as "planned" or "not on air yet" in 1963, but it was gone by 1965. If WBHM was ever really on the air that would have been an extraordinary case of short-spacing, just over 200 miles from Mobile but roughly 82 miles from WAAY in Huntsville.

I was just thinking/wondering...

What would be the most crowded 50kW nighttime situation - as in most co-channel stations with 50kW nighttime authorizations in the smallest area?
One I know of is 1580 - KBLA, KMIK and XEDM in Santa Monica, Phoenix and Hermosillo.
I'm aware of 1010 CFRB and WINS which I think may be closer than any two in the 3 I just mentioned, but I'm not sure what if any other co-channel 50kW is relatively close by.

Another thing, speaking of less-than-awesome groundwaves...
Are there any places where, because a metro area is so large and the ground conductivity is so terrible, it's possible to have TWO co-channel ND 50kW (daytime) stations (each with radiators at least 90° high and normal ground systems) below, let's say, 1400 kHz serving different segments of that same metro area?
