Hello 222 ops,

The Moon will be rising right in the middle of the 222 MHz Activity Night. My Moonrise here in Maine is at 0000 UT or 8 PM local time. Condx are about as good as it gets with very low degradation from cosmic noise and the moon is getting very close to Earth, so path attenuation is less.  I will be on 222.085 running Q65B-60 2nd sequence calling CQ.  I will be monitoring the HB9Q 222 MHz Chat page. I anyone is at all interested in seeing if EME is possible for them, now is the time to try.  Local activity dries up at about 0100 UT or 9 PM local time on the East Coast. I will start calling on EME right around that time. The Moon will be rising across Indiqana and Illinois then. The Moon rises for KF0M in EM17ho near Wichita KS at 0145 UT. If you are interested, please let me know on the HB9Q Chat page on Tuesday evening. Faraday rotation can mess things up, but it will be possible to be heard here with as little as 200 watts or less depending on how much loss you have in your feedline. I have worked a  100 watt station, but it is difficult and requires things to be lined up. Tuesday night will make things easier for sure.  If you are on the West Coast, your Moonrise will be around 0330 UT. I might not last that long if I do not know you are going to be there. All the more reason to check in on HB9Q 222 MHz. A good heading for the midwest is 78 degrees for Moonrise. WSJTx will give you accurate headings in the astronomical data. I am sure there will be a few EME stations active. W7JW has a big signal, and K3SK is sounding much louder now that he swapped out his old array for a K1FO array. The difference is very noticeable.

I looked at the tropo scene and Tuesday night does not look good. There is some enhancement along the East Coast in spots, with the best area in the SE USA. Inland paths will be without any enhancement.  In other news, I managed to contact  the power company and they have started fixing some bad power line noise that was bothering me on 222 MHz. It peaked at 270 and 295 degrees, with a weaker source at 225 degrees. The big offender was a 3 phase lightning arrestor. When they pulled that off line, the noise dropped a bunch. They promise to fix the rest in the next week or so. I have my fingers crossed.

So make plans for Tuesday evening. Send the XYL shopping. Put bowser in his crate, and chain any little kids tight in the cellar so you have no distractions.
