Other / UNID 6926.9 AM 0055 UTC 01/06/2016
« on: January 06, 2016, 0058 UTC »
Hearing bits and pieces of music on 6926.9 AM, signal will pop up for a few seconds and then disappear. This has happened a couple times in the past few minutes. Perhaps somebody is doing some testing?

Shortwave Broadcast / UNID 6870.1 AM 0000 UTC 01/06/2016
« on: January 06, 2016, 0001 UTC »
I'm seeing a carrier at 6870.1 kHz or thereabouts.  I can't hear any audio in AM mode but in USB mode I hear what sounds like it could be music at the noise floor.  There's lots of static crashes, hopefully somebody else can hear it better than I can (I'm listening on the K2SDR WebSDR remote).  There's another continuous signal on 6869.7 kHz that creates a heterodyne when tuning 6870.1 in AM mode.  Add the carrier on 6872 and its a mess.  There's something there though.

0003 - CW heard, another carrier pops up on 6872 kHz
0005 - 6872 carrier gone, there are several groups of pescadores around this frequency (namely 6868 kHz in LSB mode) and they're not helping either.  Maybe its just my imagination combined with the various signals mixing together  ???

Utility / Pescadores Very Loud on 6900 - 6950 kHz 0030 UTC 01/08/2016
« on: January 05, 2016, 0035 UTC »
Normally I hear these guys at much lower signal levels than pirate stations.  But, for whatever reason, they're much louder tonight.  Hearing S9 level signals on 6900 kHz LSB and 6950 kHz LSB, with weaker signals on 6905 kHz LSB, 6925 kHz LSB, 6930 kHz LSB.

At least they're staying on LSB.

Hearing music right at noise level, now with some guitar.  Carrier seems to be at 6924.20 or 6924.21.  Some sort of pulsing noise QRM/QRN at points as well as some peskies on the LSB.

Fading up a bit now, can hear vocals and horns (I think).  Lots of noise coming in with the signal.  

0233 - ID heard.  Captain Morgan Shortwave!  Into more music.  Seeing a weak carrier right on 6925.0 as well come and go with the fading.  
0236 - Captain Morgan ID (with email address)
0237 - Signal has come up a bit more.  Can actually make out the music a bit better.  Carrier a LOT brighter on the waterfall.  S7 signal level, just barely touching S9 on the peaks.  
0241 - Fading has become more pronounced, but I can hear some great blues music on the peaks.  
0243 - Email address/ID, into more music.  Holding a S7 signal level with a bit less noise then there was ~10 minutes ago.  Nice audio on the peaks.  
0248 - OFF?

North American Shortwave Pirate / UNID 6925 AM 2000* UTC + 12/28/2015
« on: December 28, 2015, 2101 UTC »
There's been a carrier on 6925 AM on the K2SDR WebSDR waterfall since I started listening to the UNID on 6925 USB that was playing Beavis & Butthead audio.  Per Dimbulb in that station's log thread, there's somebody re-transmitting an amateur radio net on 6925 kHz AM as well.  I saw the carrier stay the whole time there was activity on 6925 USB but was not able to hear any audio in LSB mode.  Carrier dropped off at 2030 UTC and then came back up, noticeably stronger, at 2032 UTC.  

After the Beavis and Butthead station on 6925 USB signed off at 2053 UTC, I'm still seeing the carrier on 6925 at 2100 UTC, much weaker than before but its still there.  No audio on AM or USB/LSB can be heard on the WebSDR or on my local RX setup, but I do hear the carrier on my local setup as well.  

Wanted to give this retransmission/rebroadcast its own thread...if there's already one floating around somewhere feel free to merge this with it admin
guys :D

MUCH stronger carrier popped up at 2102 UTC for roughly a minute and then disappeared.   ???

As of 2104 I'm hearing very weak music (I think) on 6925 AM.  Carrier is fading up and down, disappearing off the waterfall completely at points.

Beavis & Butthead on USB S6, off sometime before 2055z

 - and also -

Net on AM at S4, can only copy this if I listen on LSB to cut out Beavis & Butthead.
Must be live or recent recording since net control station is wishing folks "Happy New Year".
Signal is in/out of the noise and have not copied any net ID.
Hearing net control "Alpha Two Quebec?" working various ham callsigns (mostly from 7-land), just quick contacts.
Still going at 2055z, better copy with B&B signed off.
Net off at 2100z - Finally got the Net ID, "The Noontime Net"   http://www.noontimenet.org/
Music now...


1404
Seeing a carrier slightly below 6935 kHz.  Looks like 6934.75 kHz or thereabouts.  No audio but there's definitely a carrier there of some kind.  S5 signal level, just above the noise floor at this point.

Gone at 0309 UTC.  Anybody else see/hear this?

« on: December 20, 2015, 2200 UTC »
Have a strong carrier at roughly 6900.3 Showing 6900.34 maybe 6900.35 kHz on the K2SDR WebSDR.  No audio heard yet.

2200-2203 UTC - Carrier being switched on and off.  Maybe somebody tuning up?  Could be closer to 6900.4 kHz

10/11 meters / 27815 AM Spanish Language YL Dispatcher
« on: November 09, 2015, 1540 UTC »
This is a new catch for me.  Usually the taxicabs hang around the "lows" (25-26 range) as opposed to the higher parts of 11 meters closer to 28000.  I found this one while tuning around for UK FM activity.

27815 AM.  Signal is anywhere from an S4 (nearly the noise level at this location) to a loud and clear S9.  Hearing the female dispatcher only.
