10 kw
on 1610 can produce a whopping daytime skywave. I have heard the X band
stations in Buenos Aires as much as 1000 miles south, with SW like propagation.
Since there are no other X banders, this reception is pretty common.
In
fact, on a clear lower frequency, daytime skywave is not unheard of. In
the 60’s, I heard 1035 4VEH from Cap Hatien in Cleveland, OH,
over 2,000 miles away on 10 kw. This was classic noon-hour winter skywave, but
the greatest distance I ever heard.
During
one of the CONELRAD tests in the early 60’s, I heard both low and high
band skywave at 11 AM EST with stations from Nova Scotia, Manitoba and
Saskatchewan heard in Ohio. No way any of these could be groundwave. Clear a
channel, and you can have daytime skywave. On 1610, you have shortwave-like
propagation much of the time.

Subject: Re: [IRCA] 1610 signal
Not to be in the least
argumentative, but is that true at the times reception reports were made?
Certainly at night, but what I saw were reports between 7 and 9 am est.
Steady signals from two sources received remote from each other -- Florida, Illinois
-- doesn't seem unlikely.

Not very likely, however the signal was quite strong
and exceptionally stable. That would seem to rule out
multiple stations. At full 10 KW that part of the band
really skips.
