Not a good day yesterday :-( Primary tasks were:

Sort rotator out - failed, looks like an Arduino problem.

Sort 23cms interference - at least we know now it is a signal on the North aerial on 1242MHz. But lost for solutions at moment - and the mast head pre-amp box screws are ceased up.

Sort media / picture card reader - failed, buy new or replace capacitors.

Sort BH link audio - failed, looks like a rxr problem.

Sort RB-TV auto switch over
- failed, looks like detector circuit has died. Back on DTMF 775

Replace SDR 10 GHz LNB with locked version
- done but still drifts!

In view of the above and the current rack arrangements we have decided to do a rebuild in to a 5ft rack which I have available - likely to be started in 2 weeks time.

During the rebuild we will sort out the above problems, implement RB-TV switching, automatic BH linking and look at potential of integrating the original HV 23cms aerial switching system. Likely to be off air for a week....

But it's still on air now so keep using it :-)
