Switched on this morning and the usual MER of 8 + on the beacon was just 4 and a bit
Checked on Goonhilly and all looked normal.
Out to the dish to see if the LNB was at 7 o'clock..all OK
Yesterday I re-instated my wideband 10 Ghz link to my friend G4UTM 8K across the valley ...an lnb turned inside out to transmit on 10Gz with about
10 mW output on 10370 ..the dish is behind the 1.2 M dish pointed at Oscar 100 but obviously enough adjacent signal to upset Minitune !
Switched off the tx and 8.3 MER restored
QRM on Oscar 100
Re: QRM on Oscar 100
The beacon signal also goes down when other signals are on the transponder.

MER 10.2...how big is your dish!!??
Re: QRM on Oscar 100
It's 10.5 - 10.6 when other stations are not on. The dish is 2.4m but I am concerned it is not optimum as others (including me) see similar figures with 1.2m dishes. However, the maximum MER is limited by the uplink so above 10 it's difficult to see differences.
