My HumaxPVR9200 shows BBC channels to have lower signal Powers than other channels. This results in occasional drops in signal Quality accompanied by drop out of picture and sound. Why should this be when all non-BBC channels don't suffer even when they share a multiplex with the BBC? BBC Powers register about 60 and non-BBC 80.
Thanks, DH

Further to my posting of 28Aug. I am receiving Chesterfield transmitter at S402JH where DSO is completed, but I am still getting dropout on BBC channels and according to my PVR the signal strength is the same as before DSO. Will the signal strength be increased? This site doesn't report any future intention to do this so we might be left with a permanent problem with BBC reception. I already have a mast head booster on my roof aerial and the O.S. map shows us to be line-of-site to the transmitter. I understand some friends in this area have the same problem. Any further comments please?

jb38: I've just been comparing my LG TV MUXes with the Humax PVR and you are right, automatic tuning has given different results on the two receivers. The Humax has selected Ch57 whereas the LG has selected Ch26. I am going to Manually tune the Humax now hoping there are no complications which might have caused the Humax to have rejected maybe too strong a signal.
Thanks for your help. Do you think Ch57 and 60 I am receiving come from the Hasland relay?

Paul S Chapman: Hello Paul, I have the same Humax as you and I suspect your problem is due to Resetting to default which turns its internal power supply for the mast head amp. off. You have to go to the relevant part of the Menu and turn it on again. This is not possible when doing an OTA SW update for the PVR. I found the only way to do that is to use an external PSU which feeds thro the coax to the aerial. If you are already using an external psu disregard all this. I hope this helps.

jb38: Wrt my previous postings. I did a manual retune as in the user manual which is a little difficult to follow. To my suprise it replaced C57 mux with C26 rather than keeping both muxes. This is what I wanted since it only adds to the confusion to keep the unused mux. Signal Strength is up to 90% and Quality 100.

Regards, DH
