1st Trans-Atlantic E-Skip

It wasn't on TV or any of the other broadcast bands, but I'm still happy to receive my first Trans-Atlantic VHF signal yesterday via E-Skip mode rather than F2 Skip. It was also my first VHF DX from Africa.

The station received was EA8DBM Tenerife, Canary Islands, a ham station transmitting CQ and QRA messages on 50.1 MHz in Morse Code. Time of reception was 1:48 p.m. EDT. The distance of 3,591 miles broke my old record of 2,491 miles to TV Channel 4 Trinidad.

Another odd-ball TV station

While we're on the topic of strange-acting analogue TV carriers, I found another one yesterday during an E-skip opening. So far it's a UTV (unidentified television station) as I could not get any discernible video. It really is odd as the carrier seems to FM-modulate then narrow again. It was on channel 5z. Time of reception : 9:28 p.m. EDT. The signal seemed to peak west. Openings to Nebraska-Kansas, Manitoba and Alabama were active at this time. Target Area: Missouri ?

Spectrum capture and audio version are below :

CITO-TV 3 Timmins turns into a police car

This morning fellow DXer Ed Phelps in Kentucky reported hearing an analogue TV video carrier on channel 3+ that sounded like a police siren. Intrigued, I checked and found it too.

It appears to be CITO-3 Timmins, Ontario. At a distance of 376 miles, I can normally see the carrier from this station, and occasionally hear the audio. This morning the signal was enhanced. What you see below is a screen capture. At 61.25 you can see regular CICI1 Elliot Lake. At 61.26 you can see the misbehaving CITO carrier.

It really does sound a police siren, especially when off-tuned. The first audio file below is the sound of the carrier in USB. The second file is the carrier off-tuned.

Now Ed Phelps is 878 miles from this station. He is likely receiving it via meteor scatter mixed with some lingering ionoscatter. Mike Bugaj in Connecticut also reports hearing the signal.

CITO's actual FM audio on 65.76 does sound normal, by the way.

For how long will CITO be an unintentional police siren alerting DXers of its presense for hundreds of miles around?
