Peskies / 4747 kHz USB Scottish Fishing Boats vs. Arabic Comms 2202 UTC 21 Feb 2025

« on: February 21, 2025, 2206 UTC »

Hearing two sets of QSOs on 4747 kHz USB, 4.747 MHz USB 4747.0 USB, very thick Scottish accents, also heard Arabic language, then somebody (in English) said "uh, Mike Alpha Romeo?!" (with a thick accent).  Possibly three groups of folks on frequency at once.  Received via Wessex UK SDR (SW UK) G8JNJ SDR at 2200 UTC (tune in time) now the frequency is clear just past 2206 UTC / 2207 UTC.

Peskies / 6710 kHz USB Arabic Language - Fishermen? 2155 UTC 21 Feb 2025

« on: February 21, 2025, 2156 UTC »

Received via Wessex SDR (G8JNJ SDR), tune in time: 2150 UTC on 21.02.2025.  02/21/2025 21-FEB-2025.  Frequency:  6710.0 kHz USB 6.710 MHz USB.  Two or three OMs very talkative, can hear engine noise in the background...very informal QSO.  This is in the off-route aeronautical band (in other words, military aircraft / military band).  Good signal strength, clear frequency.

« on: February 21, 2025, 1953 UTC »

26950 kHz paging signals - pager signals noted at 1950 UTC on 21.02.2025 - 02/21/2025 - February 21, 2025.  Listening on the W3HFU SDR receiver (900 foot sky loop antenna).  German 80 channel FM CB radio signals coming in on 26.925 MHz FM and 26.935 MHz FM - DE mode channels 77 and 78 - German language comms on 26925 FM and 26935 FM.  Some Mexican taxi cab comms mixing in (in AM mode) on 26.935 MHz. 



Tuned away from 26.935 MHz at 1953 UTC and the German language comms are still going strong

10/11 meters / 26.650 MHz Data Bursts / Paging European Pagers 21 February 2025 W3HFU SDR

« on: February 21, 2025, 1949 UTC »

Noted activity on 26650 kHz 26.65 MHz 26.650 MHz, narrowband data and paging signal data bursts.  Usually 4.5 kHz - 5 kHz bandwidth.  Fair to good signals.  Likely European on site hospital paging systems.

10/11 meters / U.S. Truckers or Logging Trucks 25.705 MHz AM

« on: February 21, 2025, 1942 UTC »

Received on the W3HFU SDR with the 900 foot sky loop antenna.  Frequency 25705 kHz AM.  25,705 AM 25.7050 MHz AM.  Two OMs talking about tire pressure (no, seriously), spare tires and other topics.  Sounds like they are pretty close to each other, talking about roads, very informal QSO, likely two guys running export radios for local comms.  Since one of the two stations is pretty far off (25707.8 kHz!) I am including the carrier frequencies.  Yep, its truckers - they're talking about picking up deliveries, loads, etc..  At 1942 UTC, heard one trucker say "I dunno when I'm gonna go to Buffalo"

25707.8 kHz
25705.2 kHz

First tuned in at 1940 UTC.  Had to set receiver to regular AM mode.  AMN is too narrow considering how off-frequency the one guy is.

10/11 meters / UK and European Paging Signals 11M 26 MHz/27 MHz 21 February 2025

« on: February 21, 2025, 1937 UTC »

Messing around with the W3HFU SDRs and local receivers.  26.695 MHz and 26.745 MHz both with POCSAG like sounds in FM mode on my handheld receivers. 

Noting some paging signals on 26695 on the SDR receivers around 1934 UTC / 1935 UTC (1434 / 1435 U.S. Eastern Standard Time).  Propagation is slowly moving towards Latin America and domestic U.S. stations.  American truck drivers coming in nicely on 26.735 MHz AM and 26.755 MHz AM.  Mexican taxi cab company on 26.765 MHz AM noted at 1935 UTC.  Yep, our favorite YL taxi lady on 26765 kHz AM.

Techno music noted in FM mode (!!) on 26.725 MHz at 1937 UTC.

Frequency / QRG   27195 kHz 27,195
27.195 MHz FM

Multiple data bursts (fast frequency shift keying), MFSK and what sounds like POCSAG or CCIR paging signals on top of each other on 27.195 MHz.  4.5 kHz to 5 kHz bandwidth for the constant nonstop data stream signal.  Received via the W3HFU SDR.  Received locally yesterday evening around 3:45pm or 4:00pm Eastern time in Richmond, Virginia.  My Pro-106 scanner (also known as a Pro-651 scanner) actually decoded the FSK bursts as 107.2 Hz CTCSS tone and 118.8 Hz CTCSS tones which is not unheard of for things like OTH radar as it falsely decodes the PRF as a tone or DCS code, but still unique for the RCRS frequencies.

« on: February 12, 2025, 1917 UTC »

Identical to the signal (signals) noted in the previous log - received via the same W3HFU SDR receiver.  Nonstop data stream.

Sporadic AM voice comms, Spanish language (from what I can tell, the AM voice signals on frequency are weak to fair...barely...).  Noting the AM carriers down in the noise on/around 27.195.0 MHz at/around 1915 UTC, 1917 UTC

10/11 meters / 29.875 MHz FM Asian Fishermen Chatter [W3HFU SDR] 2154 UTC 3 February 2025

« on: February 03, 2025, 2157 UTC »

Received via the W3HFU SDR [900 foot sky loop antenna], tuned in at 2150 UTC.  Signal strength very weak, but some fade ups noted...around 2157 UTC.  Activity also very faint on 29.900 MHz FM, likely also fishery radio chatter.  29875 FM is one of the busier frequencies for sure.  I haven't heard these guys on US based receivers in a while.

10/11 meters / 27.195 MHz Nonstop Data Stream + MFSK Bursts [RCRS] Via W3HFU SDR 3 Feb 2025

« on: February 03, 2025, 2038 UTC »

Noting this basically every time the band is open.  Possibly out of South or Central America.

27.195 MHz data bursts going nonstop, also Mexican taxi cab dispatcher on 27.195 MHz AM in the background.  Lots of activity today.


Center frequency roughly 200 Hz off-frequency, 27.194.8 MHz 27194.8 kHz or so.  Not to bad at all and well within the FCC Part 95 Subpart C RCRS regulations for frequency accuracy.  +/- 1.35 kHz from center frequencies 26.995 MHz, 27.045 MHz, 27.095 MHz, 27.145 MHz, 27.195 MHz and 27.255 MHz.  If the power output is 2.5 watts or less the frequency accuracy requirement is even more "loose" and becomes +/- 2.7 kHz from the center frequencies.  Bandwidth limited at 8 kHz, so it is well within that as well.

27192.6 kHz - 27197.3 kHz - so we're looking at 4.7 kHz, 4.8 kHz bandwidth.  Maybe call it 5 kHz bandwidth

Peskies / Russian Comms 100 Meter/90 Meter Band 3000 kHz 3 MHz Area 28 Jan 2025

« on: January 28, 2025, 1755 UTC »

Received via G8JNJ SDR receiver, tune in time 1737 UTC. 

These guys are all off-frequency, so I'm guessing at what frequency they think they're on.  AM mode, often with some noticeable FMing or stronger signal on one sideband over the other. 

2960 kHz - 2960 kHz, 2959.4 kHz, SSB activity also on frequency, see below

2980 kHz - 2978.7 kHz

3000 kHz - 3002.7 kHz, 3001.5 kHz, 3003 kHz, 3002.2 kHz

3020 kHz - 3020.2 kHz, 3020.75 kHz, 3019.9 kHz, 3020.3 kHz

3035 kHz - 3033 kHz, maybe 3030 kHz?  3032.1 kHz...just a total mess

3040 kHz - 3038.6 kHz, 3039 kHz, 3040.5 kHz

3047 kHz / 3050 kHz?  - 3047.5 kHz, 3048 kHz, 3046.9 kHz

3055 kHz - 3054.4 kHz - very strong, 3056 kHz, 3055.6 kHz

3060 kHz - 3060.5 kHz, 3061 kHz, 3060.3 kHz

3070 kHz or 3075 kHz?  3073 kHz, variable frequency, wobbly AM carrier

3090 kHz - 3089 kHz, 3090.4 kHz, 3091 kHz

3100 kHz - 3103 kHz, 3105.5 kHz, 3014.9 kHz,

3115 kHz - very busy - 3114.9 kHz, 3115.2 kHz

3125 kHz - 3126.5 kHz, 3124.5 kHz, 3127 kHz, 3126.1 kHz

3137 kHz ?  3137.5 kHz, 3137.7 kHz, 3138 kHz, 3136.9 kHz, lots of stations on/near frequency

3150 kHz - 3148 kHz, 3150 kHz, 3152 kHz, 3150 kHz LSB also active???

3170 kHz - very busy - 3170 kHz right on the money 3170.0 kHz, 3169.6 kHz, 3168.5 kHz very terrible heterodyne

SSB activity:

2910 kHz USB - very active, Russian comms
2920 kHz USB - non stop activity at 1747 UTC tune in
2930 kHz USB
2960 kHz USB - heavy QRM, possibly legal legit comms on frequency?  Slavic language

3176 kHz USB - UNID language comms
3155 kHz LSB - Russian language

Peskies / 6678 kHz USB French Language Comms 1730 UTC 28 Jan 2025

« on: January 28, 2025, 1736 UTC »

Received via the G8JNJ SDR (KiwiSDR 1) or Wessex SDR.  Lots of activity on the bands in the 1630 UTC - 1700 UTC - 1730 UTC ballpark. 

Causing some QRM to 6676 kHz USB 6.676 MHz USB VOLMET frequency broadcast SEA 1 frequency 6676 USB.  6678 kHz is much stronger at this receive location.  Operators talking about antenna types, typical radio operator type chatter.  I'm logging this because they're using USB instead of the more commonly used LSB on the 6.6 MHz EC band Echo Charlie band or 45 meter band. 

For example, there's a lot of activity on 6666 kHz LSB, 6650 kHz LSB, 6645 kHz LSB, 6640 kHz LSB and 6633 kHz LSB, just to name a few.  French language chatter on 6757 kHz USB as well. 

There's more freebander activity than legit aeronautical comms on the 6525 kHz - 6765 kHz band.
