With a 1,8 M CM-antenna I can´t get 12 382 H at all right now. That transponder and 12 422 H (which is on 2F and BBC uses from time to time) is by far the weakest and as ocean04 wrote 12 382 is also on 2F.
I have been able to receive 12 422 on rare occasions (when in use) but 12 382 seems impossible. It might be worth mentioning 12 304 H is pretty weak here too. However that transponer is on 2E.
But generally, Maximum xo-11 and that AK54-XT2E-F quad have been good for weak levels on whatever dish they have been used. About MTI got some other AK54's (the big white ones XT2N), those I have never managed to get any decent results for weak signals.
