This would be perfect, and I have a spare android phone that I've now installed the Krkadoni app onto. However the main issue with this is that you first need an E2 box connected to the network via ethernet, which may not be possible in some places. However today I'm going back to one of the places that I was struggling to perform alignment to 28.2; now being a lot more confident with using the simple buzzer/needle meter. If I manage to do it then I'll reconsider buying the more expensive sat finder, and that'll all be thanks to you guys!!!!!!!!!
