Gosh things move FAST!
Just this morning, Analog TV was turned off, and VHF channel 7 was vacated. While playing with rtl-sdr, I realize that there’s an OFDM signal in 184.500Mhz. I don’t remember seeing it right after the 9am switch off. Maybe it was there and I just didn’t notice, or it was obscured by something else. It’s coming through pretty strongly now.
Getting out TSreader shows me it’s SBS Sydney occupying 184.500Mhz although the broadcasted Network Information Table still has the “old” data of 571.500Mhz at 64-QAM, Code Rate 2/3, Guard Interval 1/8. Is this a plan to “shove” all of Sydney’s Freeview into VHF? Only time will tell. I actually prefer UHF, as the signals seem less impacted by impulse noise and the shorter antenna elements make for nicer antennas which are less “bird magnets”.
(Disregard the Continuity and TEI errors – they arise due to driver issues between TSReader and the capture card. No such problems when using a TS capture tool and then processing the TS with TSReader, but you wouldn’t be able to see the frequency in the lower left corner as proof.)
A complete rescan shows the usual frequencies still remain active for DVB-T, as a refresher from my previous analysis of Freeview:
No other new transmissions were receivable from my rooftop antenna, although I only just noticed the new channel “Fresh Ideas TV”. Bet that’s another channel I don’t want to watch. I suppose one should keep their eyes peeled – we might see a “rescan” date coming up in the near future as they settle the final frequency allocations.
