VIETNAM. V of Vietnam seems to be having transmitter trouble right now (Sat 29 Feb from 1915UT tune in). I am hearing the German and French service on 9730kHz on every 8khz from 9690 to 9778khz (ie on 9690 9698 9706 9714 9722 9730 9738 9746 9754 9762 9770 and 9778)! Double checked that it's not my radio setup, and confirmed also via Twente webSDR. (Alan Roe, Teddington, UK)
