This page has some issues, one of which is that it's reported on RadioReference.com that LTR does NOT have a dedicated control frequency or signal, which is contrary to what this page suggests. This needs a reinvestigation. I'm not confident this is really LTR. --Cartoonman (talk) 15:47, 24 July 2016 (NZST)
Definatly Not LTR in any form that I recall. Recommend removing LTR reference to this and relabel as a UNID. See talk page for more details and examples. --Mbeam (talk) 21:15, 5 August 2016 (NZST)
