Very good on your reception in New Hampshire. I was calling W4HTB and W8RVH
who were trying to find me with my receiver fixed on 145.930 for the
20:16Z pass over Cincinnati. I was able to hear my downlink for about a
minute before ARISSat-1/RADIOSKAF-V reached Max El then lost it for a while
as my Tx antenna had no El control. I picked it up near the end of the
pass and heard fairly strong CW near my Rx freq. From the variation I
observe I believe the satellite is in a slight tumble as the 145.930 MHz
reception goes very weak then builds, sometimes rapidly.. I was fortunate
to get an SSTV picture through the transponder on Nov 12 when by chance I
managed to get lined up with the short antenna on the 70 cm receiver to
transmit an R36 picture.. I may try SSTV again if signals warrant. I hope
others will keep trying CW, voice or SSTV. I do observe that the signals
seem to be stronger at the sats lower altitude.
