NHK World - Radio Japan (via Bangkok)

NHK World - Radio Japan, relayed from Thammasat University Radio in Bangkok (Thailand), was logged on 2 February 2016.  A Thai language broadcast, featuring NHK World - Radio Japan news magazine and Japanese lessons, was heard from 12.30 to 13.00 UTC. Reception on the medium-wave frequency of 981 kHz was (SINPO) 25322 -- poor to fair signal due to long and deep fading, approximately three minutes apart. The broadcast was occasionally audible whenever fading and atmospheric noise did not affect reception.

Reception report was submitted online to NHK World - Radio Japan on 3 February 2016. QSL card arrived on 8 March 2016. Oddly this QSL card contained insufficient content (i.e. date, time, frequency, TX location), nor official verification stamp.  I am mystified, moreover disappointed, as to the general confirmation. I have since followed up and contacted Radio Japan requesting a complete and detailed QSL card.
