Never heard an ID in several minutes. But carrier stayed on during his
pauses to listen. At first it seemed like an HF repeater. But his contact
was barely detectable and not readable.
The only explanation for this is that both hams were really SSB, and zerobeat
to an open broadcast carrier conveniently on this shared frequency.
That cut off at 1354 UT leaving the hams and overlisteners to resume
carrier-insertion of their own.
Then same big carrier cut on 7235 kHz, covering VOA English lesson in
Korean service, which is scheduled at 12-15 UT, and making a site switch
at 1400 UT from TINIAN to Tinang, PHILIPPINES.
So this is what was really happening: Tinang was warming up on a
deliberately offset frequency, 7225 kHz, to avoid interfering with ongoing
VOA Korean via Tinian on 7235 kHz. But instead of waiting until Tinian
went off 7235 kHz at 1400 UT, Tinang made the switch by 1355 UT, still VOA
vs. VOA QRMing itself for a pentaminute.
A larger question is why IBB makes so many site switches amid continuing
language programs. Hardly any IBB frequency stays from the same site for
more than two hours, often only one hour. It's hard to believe that
propagation really requires these constant changes, complexity greatly
increasing the chance for errors or unnecessary self-interference like
this; but it keeps the engineers and frequency planners busy! Not to
mention the DX monitors.

MYANMAR Re new MW transmitter on 693 kHz: UADX member Sarath Werakoon
has meanwhile found this page on the website of Hong Kong-based Broadcast
Technology Limited, referring to a project installing a mediumwave antenna
and AM transmitter for Myanmar National Radio (MRTV) with BBEF (Beijing
Broadcast Equipment Factory). It says the transmitter is 400 kW, and the
project was completed in March 2010, so this is presumably what Jose
heard. (Source: UADX Sri Lanka)
