YL talking with OM at tune-in 2051 UTC 6925 kHz AM

Sounds like two-way traffic.  Two stations talking about government mobile jamming equipment that "drops a carrier from DC to daylight".  "Cell phones don't work, Wi-Fi doesn't work...you have to basically tell them which frequency you're going to use so they don't jam it"

Sounds like hams talking about various radio topics. 

Have a carrier at tune in (1600 UTC) on 6925 kHz AM on the K2SDR WebSDR.  No audio heard though

XFM booming in S9 to S9+20 at 0120 UTC on 6875 kHz AM with broadcast quality audio tonight.

Wavering between S7 and S9 now at 0125.  "Somewhere around here is the directory I'm looking for".  

"Broadcasting in C-QUAM Stereo from the United States to the World - this is X-FM Shortwave.  Music to the power of X!"

Some real nice audio frequency response.  Listening on the K2SDR with Sennheiser studio headphones - awesome bass and treble coverage RedHat!  Your signal sounds like you're next door.  

0129 - "The music sounds best...on XFM Shortwave"

Where Eagles Dare is another classic.  If you go with Clint Eastwood war films, my #1 will always be Kelly's Heroes.  Only in the late 60s would Clint Eastwood and Donald Sutherland be in the same movie.  "Why don't you knock it off with them negative waves?!".  Don Rickles and Telly Savalas are great in that one too.  Now I know that one's been played on 6925 kHz before too (or at least the theme song from it - "Burning Bridges" has been).   ;)  That one, along with A Bridge Too Far.  That one's got an ensemble cast that's too long to list.  I actually want to say I've heard parts of A Bridge Too Far on 6925 as well...

0039 - hearing repeater tones (or roger beeps) in the background
0047 - Heard more radio chatter in the background with roger beep/repeater tone
0053 - More chatter in the background.  Anybody else hearing this?  Maybe the transmitter is near another receiver or there's audio getting into the TX some other way.
0100 - Hearing OM singing "O Come All Ye Faithful" to cover up the sounds of digging the tunnels
0101 - "You were a Boy Scout?" "So was I! I had 19 merit badges" "I had 20!"
0103 - "With you in the cooler will we still be friends?!" "I must report this!"
0106 - Distorted audio now competing with station's audio...then roger/repeater beep
0110 - CW
0112 - SSTV
0113 - CW, then more SSTV
Tuned down to 6875 kHz AM to listen to XFM sign on.  When tuned back up to 6930 kHz USB, nothing was there.  So I'm going say signoff was with the CW/SSTV

0047 - Heard more radio chatter in the background with roger beep/repeater tone


Richard Attenborough (or Steve McQueen, for that matter) don't make it - but some do.  The Great Escape is still one of my all time-favorite films.  So thank you to the OP for playing the audio from it!  :D

0053 - More chatter in the background.  Anybody else hearing this?  Maybe the transmitter is near another receiver or there's audio getting into the TX some other way.

Hearing music and OMs talking.  Sounds like dialogue/music from the film The Great Escape

S9 signal level with nice audio

0039 - hearing repeater tones (or roger beeps) in the background

EDIT: I changed the title of this.  I've heard several classic films be broadcast (The Bridge on The River Kwai, several old film noirs such as Double Indemnity, and newer ones like Basic Instinct - not sure if these are all from the same station but...maybe they are?

I read somewhere that New Zealand legalized use of the "American 40" CB channels in addition to their 26.330 to 26.770 MHz allocation, giving 80 possible channels with the two allocations 26330-26770 and 26965-27405.  I could be wrong though.  I know New Zealand has the same UHF CB as Australia.

When you say "old fashioned radio-telephones" you're referring to duplex (or half-duplex) telephone interconnecting services using HF frequencies for communication between ships and shore stations?  Or are you talking about regular HF-SSB (USB) marine traffic?  

27025, 27085, 27265 and 27285 are the "big radio" AM channels in the USA.  27085 is CB channel 11 - which, back when CB was first allocated as a 23-channel service and required a license, CH 11 was the "calling" channel, CH10 was the "truck" channel - later changed to CH19, and CH9 was the "emergency" channel.  Many older 23-channel radios labeled 11 as such, with 9 labeled in red.  Now, channel 9 (27065) is commonly used by Latin American stations as an AM calling channel, much like 11 is used by English-language stations.  There are several out-of-band frequencies (mainly below channel 1) that are used for similar purposes.  26565, 26575 and 26585 are the busy ones for Spanish language.  26775, 26815, 26835 and 26915 are the busy ones for English language.  Next time 27025 is rolling in, check those frequencies as well.  On the SSB side, the busy ones are usually 26555 LSB and 27455 USB (both for Latin American stations). 

25-29 MHz is "anything goes" south of the US-Mexico border too.

Was hearing music at noise level for a few minutes, then "The Final Countdown" pops out of the noise with some pretty decent audio quality.  Still pretty noisy, but I can at least tell which song is being played now.

2119 UTC - Some sort of echo FX comes on over the final notes of "The Final Countdown", then modulation disappeared.  Carrier still there at S8 signal levels but there does not appear to be any modulation/audio at 2120 UTC.

2120 UTC - Just as I type the last sentence, something else comes on the same carrier...its "Rock Lobster" by The B-52s

Hearing Spanish language chatter (sounds like CB noise toys, roger beeps and echo fx) on the USB.  Seems like a Spanish-speaking OM is giving a demo of a CB radio setup (and there's more chatter in the background). Maybe there's two stations going at once?

It was only a matter of time  ;D   Ham communications have been relayed on 6925, aero comms, aviation weather, marine communications, WWV, and other two-way stuff.  Somebody had to do the same with CB/freeband

1627 - Techno music under Spanish language OM talk about "un radio Connex"
1630 - More CB radio comms
1631 - English language (British accent) OMs having a QSO about a CB simplex repeater and about QSYing "down to mid band"
1634 - Sounds like British CB operator talking to another op - "26 Alpha Tango 106 26AT106 trying to get into the repeater"
1636 - "CQ Repeater 43 Papa Romeo 50 Australia"
1703 - Russian comms
1713 - Thick Scottish (I think) accent CB radio chatter

Hearing OM singing on 6925 LSB - maybe peskie party radio?

Disappeared at 0045, came back on at 0046...sounds like the same song.

If tuned in at 6930 kHz LSB it (they?) sound like submarine sonar "pings"

Hearing beeps on 6927.9 and 6929.1 every few seconds.  Close to noise level so not sure if I'm missing some of the beeps but the timing doesn't seem to be the same all the time.  When tuned in USB mode (right now tuner is set on 6927.0 kHz USB) sounds like two different tones going at the same time.  The frequencies 6927.9 and 6929.1 are where the dots are showing up on the SDR waterfall.

DTMF tones, swelling music and police sirens at 2313 UTC.  

OM talk about "time of death" at 2314
YL talking to OM "are you vice?" "no we're homicide" 2318

Something tells me this isn't Sunset Blvd audio anymore - its still got a very film noir feel to it though

"the emergency frequency" as in the aircraft emergency frequency "guard" 121.500 MHz?  Isn't that one of the most monitored frequencies in the world? 

IF they're not fishing buoy beacons I'd say their purpose is military/government and they are "channel markers" or propagation beacons - used for the same purposes the channel marker beacons in the lower parts of HF are used for - indicating that a certain frequency band is open for propagation to a certain area.  

27.878 MHz is far enough away from most "freeband" activity for it to be a military/government user.  I imagine the Chinese could care less about frequency allocation plans in the end anyway.  I do know that the 25-30 MHz band is heavily used in in the Asia/Pacific region - take a look at this video - showing the 10 meter band completely overrun by AM intruders using 28 MHz for two-way voice traffic, recorded in Thailand:  https://www.youtube.com/watch?v=70fed-lAcxM

The 25-35 MHz region is sometimes used for Over-The-Horizon Radar (OTHR) and 27MHz is often where these things end up.  There are also ionosondes operating near or in conjunction with the OTHR activity.  Perhaps the 27878 signal is related to that. 

After all, 26-28 MHz is Japan's "1w DSB (double side band) fishery radio" band.  Here in the USA, there was a carrier on 27.650 MHz that I was able to hear 24/7 for several years (likely coming from a local military base) that could have been for a same purpose).  It has since disappeared.

27.385 MHz is CB Channel 38 and that happens to be one of the more active 11-meter frequencies out there.  It is the North American SSB Calling Frequency and has been for decades.  I know that frequency (along with 27.355) is heavily used for the same purposes in Australia/Oceania.
