10/11 meters / 27.295 FM - CB Channel 29 - German FM CB Chatter 26 Jan 2023
« on: January 26, 2023, 1640 UTC »
Heard at approx. 0830 local time (east coast of the USA) using a handheld receiver (25-1300 MHz AM/NFM scanner) and a 27 MHz telescopic (base-loaded) CB antenna.
All CB Channels active, but noted FM activity on 27295.0 27,295 27.295 MHz FM - strong German language chatter
Also basically all the paging frequencies busy, with 26.950 MHz and 26.900 MHz coming in full scale at points with numerous POCSAG signals on them.

VHF/UHF Logs, including satellites and radiosondes / 36.600 MHz FM “YSD” Morse Beacon Canadian Forces Base Suffield
« on: January 17, 2023, 0017 UTC »
VHF low band has been going nuts the past weeks.
This afternoon I was tuning around and on 36.6000 FM - 36.600 MHz FM I heard a Morse ID “YSD” followed by a long tone burst. Sounded like a VOR or aircraft navigation beacon like a NDB. 36.600MHz YSD Radio Beacon - 36.6 YSD Beacon CYSD CFB Suffield Heliport, Alberta Canada at Canadian Forces Base Suffield. This is a first for me.
1872 miles (3013 km) from receiver location in Richmond Virginia, USA.
Transmitter coordinates GPS lat/long
N50°16.00' / W111°11.00'
50.276359,-111.180189
I wanted to post this here in case other folks come across this recorded CW and tone on 36.600 MHz FM while tuning around the bands. It as a Morse recording on a FM signal, not AM like most VHF aircraft beacons…also the frequency choice is within the military 30-88 MHz band, which makes sense for that application (and makes sense for it to be in FM mode).

VHF/UHF Logs, including satellites and radiosondes / French Traffic Signal Control 31.325 MHz 31.6875 MHz and 31.975 MHz Heard In USA
« on: January 12, 2023, 1652 UTC »
I’ve managed to catch a polytone signal (sounds a lot like ROS) on 31.325 and 31.975.
Apparently these are traffic signal (traffic light) control signals from France. Very low power. Pretty decent catch during VHF low band opening.

« on: January 12, 2023, 1541 UTC »
Confirmed via the great folks at the RadioReference skip/tropospheric ducting forum - I am now able to confirm a signal that I'm hearing every time the band is open - 32.180 MHz FM with 77.0 Hz CTCSS. Spanish language taxi dispatch lady YL dispatcher.
32.1800 MHz FM - 77.0 Hz - Alajuela, Costa Rica Taxi Dispatch - confirmed use
32.1800 MHz FM - 141.3 Hz - Alajuela, Costa Rica Taxi Dispatch - confirmed use
Also 31.2000 MHz FM - 203.5 Hz - Spanish speaking taxi dispatcher - apparently this frequency/tone/user has been logged since at least 1988. 31.200 MHz FM 203.5Hz is still active, I last heard it myself a couple days ago - the same time that 32.180 MHz was coming in very strongly and the 27.5-39.5 MHz Dedicated Fisheries Radio VHF low fishing fleet chatter out of Asia was coming in on 29.775 MHz FM, 30.300 MHz FM, 30.775 MHz FM, 30.900 MHz FM, 31.100 MHz FM, 31.800 MHz FM and other frequencies.
I did some more searching, and a lot of folks have monitored these comms, including on 29.875 MHz FM, and numerous additional frequencies in the 30-35 MHz portion especially, all with the 25 kHz channel steps, and never with a CTCSS or DCS tone/code.

10/11 meters / 26.765 MHz AM and 27.755 MHz AM Taxi Dispatch - Matamoros Mexico
« on: January 12, 2023, 1535 UTC »
26765 AM - 26.765 MHz AM is coming in almost daily now, same with 27755 AM - 27.755 MHz AM. Both of these are confirmed taxi dispatch frequencies for Matamoros Mexico.
Also frequencies
26905 AM - 26.905 MHz AM - Taxi dispatch - Mexico City (Mexico, D.F.)
27765 AM - 27.765 MHz AM - Taxi dispatch - Mexico City (Mexico, D.F.)
27775 AM - 27.775 MHz AM - Taxi dispatch - Mexico City (Mexico, D.F.)
27785 AM - 27.785 MHz AM - Taxi dispatch - Mexico City (Mexico, D.F.)
27815 AM - 27.815 MHz AM - Taxi dispatch - Mexico City (Mexico, D.F.)
Among many others, I'm sure. 27.785 MHz is an interesting one, since it's only 3.75 kHz away from UK FM CB channel 19, which is 27.78125 MHz (or 27.781 MHz, or 27.781.25 MHz or 27781 FM 27781.25 FM...). The other day I actually heard the taxi dispatch lady on 27.785 MHz AM mixing with UK FM CB signals on 27.781 MHz FM!
