North American Shortwave Pirate / UNID 6900.3 AM 2200 UTC 12/20/2015

« 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.

10/11 meters / 11 meter DX 8 November 2015 1600 UTC +

« on: November 08, 2015, 1609 UTC »

All logged with Ranger Voyage VR9000 all-mode export radio (25615-28305 frequency coverage) and 11-meter dipole.


26555 LSB - Latin America SSB DX calling frequency (see also 27455 USB)
26585 AM - Mexican AM chat freq, busy
26845 AM - Carrier, strong (S9).  Could be local.
27455 USB - Latin America SSB DX calling frequency (similar to 27555 USB, only for Spanish language operators)
27465 USB - Spanish language traffic
27500 CW - Dasher beacon of some kind.  One dash every second or so.  Gone at 1605 UTC
27825 AM - Spanish language traffic.  Since this is in AM, I'm guessing its truckers.  Would say taxi if there was  YL dispatcher.

Update starting at 1745 UTC:

26585 AM - Mexican calling frequency.  Not as busy as it was earlier today.
26615 AM - Seems like the guys usually on 26705/26715
26635 AM - Spanish language with "Better Off Alone" by Alice Deejay playing in background.  Rapid fades from S9 down to S3-4
26715 AM - The usual super loud (and sometimes overmodulated) signals from Puerto Rico
27415 AM - Spanish language
27425 AM - Spanish language, with roger beep.  OM talking to other (unreadable) stations.  S3-S4 signal.
27445 LSB - English language.  Southern US accents
27455 USB - Latin America SSB DX calling frequency.  Station in Mexico calling CQ
27535 AM - Spanish speaking OMs talking.  Could be truckers since they're using AM
27555 USB - Hearing beeps.  10AD340 calling CQ requesting QSY to 27600 (said this in Spanish and then English!).
27600 USB - 10AD718 (also IDing as 10AD340 ??) working another Spanish-speaking station in Aruba - other operator corrected him, its actually Curaçao!
27665 USB - Spanish language traffic.  Busy
27675 USB - Spanish language traffic, nice powerful signals.  Operators discussing antennas and their mobile radio setups
27685 USB - Spanish language traffic
27690 USB - Spanish language traffic
27745 AM - Spanish language traffic, getting obliterated by OTH radar QRM
27775 AM - Spanish heard, with roger beeps.  YL and OM.  Possibly taxi dispatch

On a personal note, I have visited Aruba a couple years ago with my VHF/UHF scanning equipment (RadioShack Pro-96) and scanned 25-50 with a VHF rubber duck and heard several very powerful stations in AM and SSB in the 27400-27900 region.  

The very strong signals on 26615 make sense too.  Channel 9 (27065) is listed on Spanish-language 11 meter DXer websites as a AM calling frequency, and 26615 is Channel 9 "down one band".  So I bet they just flicked the bandswitch down from "D" to "C" and continued talking.

Some European DX coming in now.  Hearing a very loud Italian station on 27415 AM.  Sounds like the high power stations that usually hang out on 27465 AM.

10/11 meters / 26805 AM Mexico City La Ciudad de Mexico 1430 UTC 4 November 2015

« on: November 04, 2015, 1432 UTC »

I know this is a freeband frequency often used by taxicab companies (you'll notice the YL dispatcher) but there's now a station playing music on top of/with the taxi dispatcher lady, IDing as "La Ciudad de Mexico" followed by all sorts of roger beeps and noise toys.

This is likely indicative of another 11 meter band opening today

1433 UTC - Now hearing the taxi YL lady again, with music in the background.  
1435 UTC - OM ID something unintelligible followed by "La Ciudad de Mexico" and more music.  Now slightly stronger than the YL taxicab dispatcher.

10/11 meters / Churches On 11 Meters - CADS and WPAS - A Primer With Frequency List

« on: October 21, 2015, 2211 UTC »

Considering the upsurge in recent 11 meter activity (including DX from the UK), I figured I would write a quick bit of information on the UK's Community Audio Distribution System (CADS) and Ireland's Wireless Public Address System (WPAS).

CADS: Ofcom (the UK's communications regulatory agency) allows for broadcasting of religious and community events using low-power transmitters on the 27 MHz (CB) or 11-meter band.  As of March 2007, no license is required in the UK for operation of the CADS system.  CADS uses the "CB 27/81" (commonly known as UK FM CB) allocation which consists of 40 channels spaced 10 kHz apart starting at 27.60125 MHz for channel 1 and ending at 27.99125 MHz for channel 40.   FM modulation is the only mode allowed with 4 watts maximum power.  CADS is commonly used to transmit church services to local residents using regular CB equipment and vertical antennas.  Truly continuous (i.e. leaving the transmitter on 24/7) transmission is not permitted (although sometimes practiced nonetheless).

WPAS: ComReg (Ireland's communications regulatory agency) allows for a very similar system to CADS. WPAS transmitters are only allowed to transmit real-time audio from public events and is only available for non-commercial use.  ComReg requires registration and licensing of transmitters to be used in the WPAS.  It appears, however, that this is rarely practiced or enforced.  WPAS differs from CADS in two important ways.  First, CADS allows for either AM or FM modulation (user's choice - mode must be indicated on license application).  Second, CADS' frequency allocation is actually two sets of 40 "interleaved" channels, spaced at 10 kHz.  Channel Block LW consists of channels LW01 through LW40.  These correspond with the UK FM (and also CADS) channels 1 through 40 respectively.  Channel Block UW consists of channels UW01 through UW40.  Channel UW01 is 27.605 MHz and channel UW40 is 27.995 MHz. Straight 10 kHz spacing up through the channels.

*Legal* 27 MHz Church Frequency List:     - As you can see there is some really tight spacing between these channels.  Especially the WPAS channels.

10/11 meters / The taxis are back (26-28 MHz)

« on: October 20, 2015, 2146 UTC »

With the band opening up today, and the UK coming in nicely earlier (around 1600-1700 UTC), I decided to do some loggings:

Now that its around 2130 UTC, the European stations have disappeared and the Latin Americans dominate the 25-30 world.  I am fascinated by the heavy use the taxicab/trucking industries make use of these frequencies, especially in Spanish-speaking countries.

Here's some logs.  I must note that I can hear WWV on 25000 nearly 30dB over S9

All are in Spanish unless noted otherwise.

25615 AM - Taxi Dispatch (this is channel 1 on band A on most export radios)
25645 AM - Taxi Dispatch
25775 AM - Taxi Dispatch, other AM voice traffic, noise toys
25915 AM - Taxi Dispatch - unfortunately right next to 25910 FM (when I can hear it, which I can't today)
26305 AM - Voice traffic, likely truckers (lots of noise toys, heavy QSB)
26375 AM - Same as above
26515 AM - Taxi Dispatch
26805 AM - Taxi Dispatch with roger beeps, noise toys
27045 AM - Taxi Dispatch (this is within the legal CB band, but is not a legal CB channel.  It is, in fact, a RC frequency!)
27425 AM - Taxi Dispatch, with QRM from SSB activity on the same freq and 27420 USB
27445 AM - Taxi Dispatch
27515 AM - Taxi Dispatch (I hear this one the most often and usually with the strongest signal)
27775 AM - AM voice traffic, likely taxis
27905 AM - Taxi Dispatch

The high 25 to low 26 range seems to be the most active when the band is open, followed by just below 28.  All in AM mode.
