Hey all,
I've been helping out a local community radio station in south of Sydney sorting out their studio hardware and learning all things radio and FM in the process, I recently purchased an SDR to do some more learning and was was doing some scanning of the station and frequencies around it from my home tonight based on a listener reporting hearing another station on the frequency at areas around town and when leaving the local area...and I thought of this forum after remembering watching Dave's video on the old analog tv transmitter tour...so hopefully I have put this in the right place, if not let me know and I can move it accordingly
The station is 92.5MHz, transmitting at a few hundred watts, but nearby frequencies have the ABC transmitting on 92.9MHz from Gore Hill, the odd thing I found is that there seems to be a replication of the signal 2 station steps either side of the ABC's 92.9MHz signal (92.5 and 93.3-ish), which I am wondering if, in theory, the ABC transmitter transmitting at a considerably higher amount of kW the signal and its replica noise with it either side with this signal, could the community station's lack of strength actually be being further drowned/canceled out with the snow overpowering it when sub-optimal terrain conditions occur to the community Tx tower?
Heres a quick screen recording with audio example if that helps make more sense
still learning all things radio but googling has not found me much other than explanations of what deviation and drift is...but if its something obvious let me know and im sure we can all have a bit of a chuckle about it
thanks
