European Pirate / Re: Non Stop 90's 6926,5 AM 1914 UTC 20 Jun 2018

Hello guys,
If you got a carrier on 6926.3 kHz, there was no audio.
Sooner, when there was audio, there was no carrier that could be 'heard': the TX was wobbling so much that nothing but noise could be heard in LSB, USB and CW modes. Even The sync AM and the FM modes did not work.
I reported the frequency as 6926.5 because it was about the mid position of the range with success in AM mode. When there was no more audio, then I could measure 6926.3 by beating with the CW mode. Sounds like a 'lulu' with attempt to draw the crystal frequency.

Utility / Re: 11015 USB

« Last post by Token on Today at 16:01 »

I am going to move this thread to the Utility forum, since that probably fits the signal a bit better. If you read the Read Me post at the top of the Mystery forum you will see that that forum is really intended for mystery modes, vs source identification.

With that said, get set up to do audio recordings of signals. Without more detail than you have provided it is unlikely you will get a meaningful answer. An audio recording goes a long way to confirming a signal type.

Here is the problem, are you sure it is really CW you are hearing? There are several possible signals that operate around that frequency, and none of the better candidates are Morse code. FSK, various digital modes, and Link-11 are the most likely.

If I had to guess, I would say you are hearing the Doppler tone of a Link 11 signal. There is a relatively active Link 11 on 11016 kHz USB, this would put the Doppler tone on 11016.605 kHz, or at about 1605 Hz audio if you tuned to 15015 kHz in USB mode. So you might hear short and long pulses, that can be mistaken for CW. The fact you are hearing only U’s, V’s, and 4’s can support the Link 11 possibility, it can sound something like those characters under some conditions.

T!

SDR recording catch, AM mode for the first minute or so, then switched to USB. SIO 555.

Peskies / Rural Radio Telephone Service - Latin American HF Radiotelephone Links

« Last post by R4002 on Today at 12:01 »

Since it seems like a lot of the traffic heard in Spanish is radiotelephone related, I decided to put together a list of all of the logged rural radiotelephone link frequencies:

All frequencies in kHz, mode listed with frequency

6835 USB - Spanish language, possible radiotelephone link (last logged Jan 2018)
6805 USB - Spanish language, possible radiotelephone link (last logged Jan 2018)
6799 USB - English language, YL and OM heard talking
6790 USB - Spanish language, possible radiotelephone link (last logged Jan 2018)
6786 USB - Logged several times, Spanish language
6780 USB - Confirmed rural radiotelephone service frequency
6775 USB - Alternate frequency, lots of offsets in this portion of the band (6777.5 kHz, 6767.6 kHz, etc)
6772.5 USB - Spanish language, OM and YL heard talking (last logged Jan 2018)
6768.5 USB - Spanish language, OM and YL, heard during band opening to South America
6767 USB - Logged several times
6765 USB - Heard during band opening to South America
6760 USB - Another presumed radiotelephone link frequency
6755 USB - Logged several times
6750 USB - Logged several times, Spanish language
6749 LSB - Spanish language, possible radiotelephone link (last logged March 2018)
6721 LSB - Spanish language, presumed radiotelephone link
6713 USB - Presumed radiotelephone link, possibly just freebanders or pescadores
6710 USB - Spanish language, presumed radiotelephone link
6705 USB - OM and YL talking, sounded like a telephone conversation (last logged Jan 2018)
6700 USB - UNID language heard here
