Hi Jan, PE4WJ
I can confirm that Jan PA0SSB received the ALSEP packages.
Jan is a good friend of mine and we used to contact off the moon
432 MHz EME from 1977 to 1980
PA0SSB was using the homebrewed 6 meters dish described and
depicted in "The Moonbounce Group Part-2 " edited by EIMAC
under cat. Nr AS49-14
The last time I was in touch with PA0SSB was on AO40 and if you
contact him please relay to Jan my best remembers and 73"
Tank you so much
