if WBCQ hadn't been off frequency, it probably wouldnt have been noticed.
I was able to hear something underneath at times. I presume it was WBCQ but you're closer and in a better position to judge, I think.
ah, sorry, i totally misread the title of your post and messed up my reply to your post MDK.
after i watched your YT video a couple of times, i thought it was WBCQ in the recording with WWCR's heterodyne under it (due to WBCQ being a few hundred Hz off freq) since WBCQ plays the same talk content as WWCR.
now i understand, that was WWCR in the YT recording with WBCQ's heterodyne under it. (couldnt really see the spectrum detail in the YT video to determine who was who)
actually, despite poor receive using my TX antenna, i got the same thing you got in the YT video except that WWCR was much stronger than WBCQ since WBCQ skips right over me (not close enough for direct ground path) - the heterodyne was there but much much weaker.
WBCQ is the only USA station that is off freq by a few hundred Hz with their transmitters.
dont these guys communicate and work out some sort of airtime coordination to share 7490Khz ?
its not going to do any good when both of them are on the air at the same time, same freq but its happened many times in the past.
i know that 5130 was broadcasting for 4 straight days, day and night, on and off at varying power levels, with zero modulation.
im going to assume that you did not hear the radio mi amigo broadcast as well, i didnt.
i was going to check various online SDR's but didnt bother since i naturally assumed it would have been nothing but a heterodyne of a mess anyway.
it would have been great to hear radio mi amigo on a USA TX (other than religious yapping) but after tonights fiasco assuming RMA was monitoring it, who knows what will happen next.
on a side note, i browsed the SW bands for the better part of the work day today and all i could find was religious talk and the one lone UNID pirate that was playing "Cops".
its like the SWBC band has turned the other cheek to a vast deserted empty wasteland of static, not what i remember in the 80's and 90's.
