EME Progress - First Six Months

Here's a quick report as to how my small EME station is doing so far.  I started in October of 2012, and over the first six months of EME attempts I've been able to make 76 two-way contacts so far.  The contacts have included 58 "initials" (stations I haven't worked before), representing 19 countries, 13 US states, and 55 unique grid squares.

All contacts have been on 2 meters (144.110 to 144.160 is the EME sub-band), and using the JT65B digital protocol.  Software and hardware details are in the postings below, but mostly I use MAP65 for the contacts now.

With the small 2 x 2M7 antennas, I seem to be able to work stations as small as 4-yagi stations, although I've made contacts with two 2-yagi stations and one 1-yagi station.  Signal reports received at my end range from -16dB for the huge stations to -28dB for the smaller ones, but typically contacts are made at around the -22 to -25dB range.  Signal reports for my station coming back from the DX station's side ranged from -19 to -27dB, typically in the -23 to -25 dB range.

Most contacts have been made during the two weeks of the month when the moon is at elevations.  This seems to be primarily for two reasons:  1) there are more stations on when the moon is at higher elevations, and 2) my station sensitivity is much improved when the moon is above 40 degrees in elevation (due to local noise at the horizon).  QSO rate has ranged from zero over two weeks to several per hour during optimal conditions.
