  • Small mysteries from Portugal!

    Whilst receiving Ch A2 and A3 positive offset (55.26 and 61.26 MHz) last night around 21.50 gmt I noticed a zero beating unmodulated carrier on 61.26MHz coming and going over/under the CTV signal (on the news).. This then faded and very briefly a siren type sweeper appeared, faster than the Venezuelan one(which is zero offset).
    The 2 CTV signals(A2, 3)were not in parallel, so one or the other may have been from Ontario.

    For the past few days a strongish unmodulated carrier, zero offset has been around on Ch A2 in the late afternoon /early evening.
    I hope this isn't the Dominican Republic switching off, no sign of the warbler at the same time.

    I was going back through last night's recording and this is a little bit of the ChA3 news around 21.50z.

      I believe you were hearing CITO Timmins, Ontario, which is at 61.260 MHz. Lately it's video carrier has been running different and on the SDR screen it looks like a zipper and the audio sounds like a very fast siren. I had a screen capture of it and a brief mp3 recording but appears I deleted both of those files. If I can get a new screen capture of the signal, I will post it here for your comparison. I see it also on meteor scatter.

        Many thanks for the info, Jim. I'll keep a lookout for it if conditions allow, it certainly didn't last long but fortunately is very recognisable.
