Dish still on the tyre, been very stable. Am slowly moving towards a real install. Found a source for 4.5" tube (from oil drill supplier), minimum size 6 meters :O) That's ok, not too expensive.
180 vast improvement over the 125, all 2E and 2G under control. But 2F UK still marginal in the evenings, need a db or two. Day level up to 12db, evening sometimes down under 5,5 and failing.
So back to lnb testing and mm adjusting, as always seeing some lnb's perform better than others, even same type\make lnb may vary with a db or two. So far have found the best IBU twin (out of 3) and a good IBU quad (out of 3). The single IBU is weak. The Maximum's are good, but narrowly beaten by the IBU's on the 180. On the 125, the Maximum's are best. Go figure. Will later have to try more lnb's and the feedhorn system (thanks a lot to st1 for offering a feedhorn loan, but with shipping charges + holidays not practical).
The wifi\solo2 android satfinder app has proved immensely useful.
