The G3TFX experiment - 2m FT8 RX vertical

As promised, today I am monitoring 2m FT8 but using my V2000 vertical instead of the horizontal big-wheel. This was suggested by my old work colleague Richard G3TFX in Cambridge.

Already I am surprised by the number of stations still being received. This suggests that these stations are less dependant on polarisation than I thought, suggesting either aircraft reflection or random MS rather than tropo.

UPDATE 1015z: 12 uniques in 4 countries, despite being vertically polarised.

UPDATE 1130z: Now 19 uniques in 4 countries.

UPDATE 1405z: Now 28 uniques in 4 countries.

UPDATE 2105z: Well, the experiment has ended. Conclusion? Polarisation does not matter, so probably most DX received by aircraft reflections. Amazing. Map show stations received on 2m FT8 today with vertical polarisation.

  1. Maybe a lot of other stations are using verticals for FT8, to get omni coverage?
