Darvel (East Ayrshire, Scotland) Full Freeview transmitter
Wednesday 12 October 2016 11:26AM

KA9 2DY Aerial on roof Distribution amp.

Noticed last night not receiving some hd channels.
Re-Tuned tv youview box etc all to no avail

Noticed on the darvel site the missing channels 45 101 102 103 104 105 123 602 and 603 all are transmitted
via the same mux channel psb3 bbcb.
Previously all working all working now these channels are not being picked up by the channel scan
Dont think problem lies at home as all other channels above and below are workink well
Would appreciate some thoughts.

StevensOnln1: all the channels were fine with nothing being done to the amp have TV out in garage with freeview box running of an aerial inside the garage and no channel 45 film 4+1 which runs off the same mux channel and isn't an HD channel have feeling that it is a mux problem or some sort of interference any help greatly appreciated

StevensOnln1: The amp that I put in is from Labgear and for some strange reason all their connections are now
F plugs so think amp is a last resort at the moment. Was up early this morning checked telly and low and behold
channels have reappeared though they disappeared as the day progressed this would indicate a lack of signal strength as propagation conditions are better at night and signals travel farther. Also noticed channel 32 movie mix very pixelatted checked signal strength which was good though quality was poor. Your correct in the fact that the rest of the channel sig strengths are quite high. The mux transmitting frequency of 530 Mhz lies approx in the middle of Darvels transmitting range starting at 480 up to 602 Mhz so an actual fault in the amp is unlikely.
Curiouser and curiouser
