Thanks!

SDR recording catch, Scottie DX Mode:


23778
Here's the repeated ID I heard at 0047 sign on, perhaps someone can determine exactly what the station name is. It sounds like Cave Man Radio to me, I guess it could be Man Cave Radio as well: http://www.radiohobbyist.org/blog/mypics/0047utc-07-07-2014.mp3

Hah yes, I did mean 7 Jul 2014, I guess I was caught in a time warp.

Now hearing what sounds like old time radio programming at 1117z.

23780
Tentative ID heard at 0047 sign on.

23781
I have a carrier on 6770, but no audio. Is anyone hearing programming?

SDR recording catch. Scottie 2 mode.

SDR recording catch.  OM talking, rather muffled. Microphone in front of speaker?
OM talking about transmitting on frequencies not allowed by the FCC. I think I could hear some faint SSTV in the background.
At 1845 I heard some more SSTV, but way too weak to decode. Move the microphone closer to the speaker. :-)

Heard via Twente SDR. Good signal. Presumably a pirate having some fun. Still going at 1932z.

SDR recording catch. Possibly one of the worst sounding SSTV transmissions I have ever heard. It sounded like it was transmitted by putting the the radio's microphone in front of a cassette player speaker. While sitting inside a cardboard box.  :-)



This looks like the same image I caught the tail end of earlier today.

Here is the audio, if you want to hear what I mean: http://www.radiohobbyist.org/blog/mypics/SSTV-06-Jul-2014-1839.wav

Unfortunately, digital signals like SSTV really suffer a lot with poor acoustics. Still, thanks for the effort!

Caught the tail end of some SSTV. Note sure if it is correctly aligned or not, so the colors could be off. Here's what I got. The SDR is now running... should the op try again :-)

Every section of your antenna that is inside your house can pick up interference from inside devices. That's why it is common to use coax between the radio and the start of the antenna. While some sort of a matching transformer (such as a unun) may be ideal where the coax and antenna meet, they aren't required, and many listeners do fine without one. Just connect the antenna wire to the coax center conductor. Some weather proofing would be a good idea, so water doesn't get inside the coax. Some advocate grounding the coax shield at the antenna, others say leave it open.

Note that you should have a lightning arrestor or other protection device for any outside antenna, which should be grounded, for safety. Personally, I take the extra step of disconnecting antennas when storms are likely.  The NEC (National Electric Code) has a section on dealing with antennas and transmission lines, IIRC, which you may want to consult.

SDR recording catch, 0817 sign on with "Go Bankrupt And Die", then an unshazamble song, Yazoo "Situation", and off at 0823.
Good signal.

23789
SDR recording catch, 0625 sign on. Fairly week for a few minutes, then the signal came up to SIO 444.

23790
SDR recording catch of an other drive by pirate transmission, "Mighty Quinn" this time.
Off at 0338.
