We used our modest EME station to receive and do a live feed of data
from 4M into the online database for a couple of hours in the early
evening here in Colorado. Signal was plenty strong and we sent along a
couple hundred packets, although sun noise was a bit high just off the
spacecraft direction. We could hear the JT65B tones in the speaker much
of the time. Sample below. We will continue to feed in data as we have
time.
TLEs on the mission web site are now OK in NOVA for tracking, even
though NOVA shows an AOS of "CRASHED" because the orbit intersects the
earth after the lunar loop around.
The signal levels shown in this WSJT capture are quite strong at up to -8dB.
My EME station is 2x15 element Yagis on 38' booms, horizontal, .8dB NF
preamp on the short tower. About 17dB gain overall. Probably somewhat
less since they are cut for 144.1 and this spacecraft is at 145.980.
