[QUOTE="s-band, post: 1113178, member: 407744"] Is the term "reflection" used to mean "image response"? The image responses, for both 11.8 & 12.8LO do not correspond to LBC on Arabsat. I think that 13444V is definitely coming from Turk5A (and 13446V 1300 5/6 8PSK when it popped up). My LO is 11.3GHz and has minimal spurious responses apart from the internally generated one. It's interesting that the pair of signals that I saw here: [URL='https://www.satellites.co.uk/forums/threads/t%C3%BCrksat-5a-and-new-ku-band.177961/post-1112808']Türksat-5a and new ku band??[/URL] correspond to LBC int HD and LBC int on Arabsat Whilst I was typing this, [USER=187415]@hvdh[/USER] beat me to a possible explanation. However, for some reason, I thought Turk5A uplink was 14.5-14.75 but I can't find anything to back that up. 10994 -10950 = 44 13400 + 44 = 13444 However, if it was from LBC HD uplink to Arabsat, why wasn't LBC SD there as well, except during the earlier observations?
