[QUOTE="nelson_b, post: 1166218, member: 296628"] Indeed ..... thanks for that ..... i have this odd result on quite a few transponders ..... 11996 has weakened here now in the last hour and is no longer locking - but looking at it now on the F15 with V polarisation selected it shows 7.5 db .. with H selected it shows 7.1 db The new transponder 11977 i had locked earlier this evening was "locking" in either polarity one at 8.0 db and the other at 8.5db .. ? There are other transponders that don,t do this ... and just show signal and lock or not in only one polarity ... I will try and make a list of both examples tomorrow if the signal is good again ..... i cant see any sensible pattern to this oddity so far ... cant recall having had anything like this on the F15 in C band.
