MYANMAR 5986 It seems that a new service of Myanma Radio is relayed on 5986v in the local early morning. I've traced the new service on 5986v kHz from around 0000-0130 UTC daily, but it probably operates for longer than that. I haven't yet found any other shortwave frequencies for the new service apart from 5986v kHz in the local morning.
I don't know the official name for the new service, but it sounds like it's aimed at young adults. It carries a lot of pop music, especially covers of Western and Chinese pop songs sung with Burmese lyrics, interspersed with short announcements and occasional drama sketches all in Burmese.

I think the station Alan is referring to is probably this one:

Filed under: News, Inside Burma
A new radio station has been on the air very recently in Myanmar mainly broadcasting music with brief domestic and international news intercepting its program, according to Yangon audiences who came to notice Tuesday.
The two-and-a-half-hour morning program of the "Padauk Myay" Radio Station, broadcast in local language from an unidentified location since last week and is believed to be from inside the country, is received from 5:30 a.m. (local time) to 8 p.m. on such frequency waves as FM (frequency modulation), MW (medium wave) and SW (short wave), the audiences said.
