Hi all - mostly in Europe, Since the need to use the 67 Hz, CTCSS tone is not there any more, I have heard a funny "rumbling noise" on the downlink. That is mostly when the passes are to the West of me here in Copenhagen. I have listened for the same on FO-29 - and it is there as well. That is when adjusting my receive frequency to correspond to an uplink of approximately 145.920 MHz.
Can anyone confirm this ?
If yes - do you have any idea what it is ?
