We are currently testing a new antenna system for medium wave.  This is running at quite low power, so it should be challenge to hear.
Please let me know what your receive level is, this will serve as a benchmark for later tests.

I am looking forward to your reports!

Same here, mostly a weak carrier but I did hear some threshold audio about two minutes ago, music, but I couldn't ID it.  I'll be sticking with it until I see the carrier go off.  Thanks for the MW test - very cool!!!

0009z-0015z: Carrier first noticed between these times on 1720.

0029z: Carrier returns again.

0051z: Signal came up a bit and I could hear some audio again, unid song, and then OM announcement, possibly a familiar canned ID, perhaps "there...there.." and back down to a carrier again.

0142z: Peaking again slightly, very faint modulation heard, sounds like music just above the imaginary level.  Was short-lived, back to carrier...

0144z: Carrier went off

Same; just a very weak carrier here on the Wellbrook.  I have been meaning to install the MW resonant loop out back this week, but 3 foot snow drifts in the antenna garden have nixed that idea.

0100 Still straining here, but no audio.
0136 Still nil.
