11342.5 kHz 11.342.5 MHz 11.3425 MHz only 0.5 kHz away from busy aircraft HF-SSB frequency ARINC MWARA aero aircraft New York Radio interference QRM alternate frequency SELCAL SELCALL selective calling
Log starts: 1730 UTC on September 1st, 2017.
Hearing Spanish language chatter on 11342.5 kHz USB, controller moved aircraft to alternate frequency due to QRM. There's a strong data carrier on 11344 kHz (center frequency) as well, making copy on the Spanish speakers difficult too. Lots of whistling and casual chatter. Very close to heavily used MWARA aero aircraft air traffic control ATC frequency 11342 kHz USB New York Radio air-to-ground frequency 11 MHz aircraft band.
Seriously, why don't they just go a couple kHz up or down?
1733 UTC - still hearing Spanish traffic, lots of whistling and general QRMing of other stations heard.
1734 UTC - MWARA controller ordering aircraft to switch to 13 MHz frequency, then SELCAL check with JetBlue flight
1735 UTC - another SELCAL check, seems like controllers are continuing to use the frequency despite heavy QRM from Spanish speakers and data carrier
