23, 26 and 30 were tested at CP according to DS posters. BBC2 analogue and C5 (ex-Croydon) were not tested. There are more tests tonight. The tests were NOT run at full power, DS posters indicate the ERPs were at 50kW on the post DSO frequencies.

mrdtv: Depends who you believe. Considering I was getting the same readings percentage-wise on the digital tests as for analogue signals, I'd say it was full power, though of course the digital box isn't designed to measure an analogue signal.

If I'm right about the calibration of my box's strength meter, my usual level for low-power digital at 35% translates to 56 dBuV, while the high-power test at 60% translates to 71 dBuV, or 15 dB higher than current values. The increase at DSO is only supposed to be 10 dB. 15 dB would be near 600 kW.

BBC Two analogue was on noticeably lower power (showing only 40% on C33 on my PVR, though again measured as if it were a digital signal), which was attributed to it running from the back-up transmitter at Croydon.

Mike:

I think we will see a full six mux high power test tonight. It also appears some of the relays were radiating on post DSO frequencies.
