According to the most recent filings, KMRI was back on the air temporarily from March 1 through the 4th, apparently at an STA power level of 1kW. They have also received FAA clearance for construction of the new tower and say that once the FCC approves the new application for the facility and they get local building permits they will construct it promptly and resume normal broadcasting.
FWIW their license expired last April but their application for renewal is still pending.

Anybody else hearing a strong second-harmonic of 1010, with a huge hum, on 2020? Wonder if it's just the rain, or something else.

Reading between the lines from the STA filing I don't think the new tower has been built yet. So if there's something going on it probably isn't that.
I don't see anything at 2020, but I have poor reception down at those lower frequencies.

I hear no 2nd harmonic nor buzz at 2020.

It was gone last night, and earlier this morning, but is back faintly now. I'm hearing it on an ICOM R8600 with a spectrum display, fed by a Wellbrook loop antenna.
I wonder if it's only showing up on their daytime power, but not when they go to the night or Critical Hours (low) power.
If KMRI is operating just for a few hours occasionally (to keep the license alive), they may be duplexed on to the KIHU-1010 tower, or maybe a long-wire antenna attached to it. Does it say in their latest filing?
I can hear KIHU audio under the noise.

The temporary facility is a 24 foot top loaded vertical antenna and used the existing ground system. Could tying into the ground system be the cause?

I thought I remembered something about a vertical antenna. I wonder if the ground connection is still intact. Maybe there is enough energy from the adjacent 1010 antenna, that it's reradiating the second-harmonic that should normally be filtered out within the transmitter.
Or, maybe there's a mismatch somehow.
I'm monitoring for signs of the intermittent RF mixing that occurs in that end of the valley, which usually only happens in acclimate weather, but only seeing the 2020 now. But, the hum is intermittent, and the strength changes intermittently.

The new application has been approved. I have no idea how to check for building permits but returning the station to the air permanently might be in sight.
