Hi Steve,
You might consider another center frequency for the LoRa (and even the 4fsk) transmitters for your next flights.
The rounded frequencies ( 00, 25, 50, 75 ) are usually crowded, but the in betweens at 12.5 37.5 and so on give often just enough space to fit 20.7 kHz LoRa or 2.7 kHz wide 4fsk.
The attached file is the radio screen of one of our famous listeners from London :-)
