Hi satesco,
12698 V 35000, 9.4-9.5dB on 1.4m dish
12725 V 7500, ~12.5dB
for 12698 V I have moved the antenna 2 steps to West from positioner to obtain max signal, so I think that 12687 V 28800 from 1W is from THOR 7 satellite and comes with high signal, makes reception difficult on small dishes for 3W position.
