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.

23826
SDR recording catch, 0625 sign on. Fairly week for a few minutes, then the signal came up to SIO 444.

23827
SDR recording catch of an other drive by pirate transmission, "Mighty Quinn" this time.
Off at 0338.

23828
SDR recording catch, 0329 sign on with rock music, sounded like ZZ Top "I heard it on the X"
Off at 0332.

23829
SDR recording catch. 0321 sign on with instrumental rock music, unshazamble here. Could have been off frequency?
Off at 0324.

23830
Another drive by pirate transmission on the SDR recording, 0309-0312z with instrumental (horn?) music.

23831
SDR recording catch, 0240 sign on with instrumental music, had a Latin American sound to it. Off just before 0243.

A Drive By pirate transmission, as ByteBORG calls it :-)

23832
SDR recording catch. 0212 sign on with a very strong signal, S9+15 dB.
Off at 0304. Thanks for the show!

23833
Noted here as well on the SDR recording. Same details as the others. The 6974 LSB transmission was stronger than the later 6970 LSB transmission. I'm still unsure as to whether this is a pirate or pescadore.  The use of LSB makes me wonder if it is the latter.

23834
S9+10 at 0130z. Great signal and audio as usual.

23835
Just signing on now, very solid S9+20 signal.
