Update 20150602:
"Today arrived other amplifier made by a DRM-Brasil member, all without involving money (this is why things walk so slow). So EBC people will carry some tests with it, and after that transmission should restart, with a signal with better MER.
As the setup has little power, the crew involved is trying optimize the quality of the signal. So no signal today, and nothing happened yesterday also..."
This is not only good but triumphant news! Thanks to Brother Rafael.

"Tests will resume on Monday (1st June).
We'll inform the frequency soon.
Btw, on Thursday happened the first DRM SW transmission in Brazil! With 130W signal at 9755kHz was received by Claudio 780 km far away.
Big thanks to Michael Feilen, all guys at EBC and Ministry of Communications
involved in the trial.
Next week we'll be able to get another final stage amplifier in order to check if
we can get more power out."
