I have made 2 different successful short duration CW transmissions through the ARISSat-1/RADIOSCAF-B transponder over the last 2 days. Called CQ with no replies. My receiver fixed to receive on 145.934.5. Transmissions made near 435.950 and varied to receive. I received back my signal very weak but clearly readable. Will be trying again with above freqs on Monday Sept 19, 2011 on passes over Cincinnati, Ohio beginning 13:50Z. Be listening for anyone trying to connect. Farrell Winder, W8ZCF
