We tried using Chris' brand new un-cut whip, with simular results !
When I fist installed the sirio I snipped a fair bit off it to get good readings, so not sure if or how much further I could go, also am I correct in thinking when you only do this when you can calibrate it in on
ch20 ?
The only difference with the base from when you sent it back to me Jon is that I ferked the upper grub screw up so now it has a small screw in bollt instead.
