Hi Rick, The pass around 2130 UTC today (2.30pm local time) was a nice and high pass over central Arizona. I had two stations going, copying the downlink and recording what I received on both stations. I really need to get set up to use my Elk with more than one radio, or hold two Elks as the ISS passes by. :-) I'm hoping to decode what I copied tonight. I copied about 1/2 of one picture, and all of another. I think there may have been one spot where my SDRplay/HDSDR/Elk setup had something pop up and interfere with the downlink - a truck passed by my yard at that time. 73!

Hi Ted, Try RX-SSTV , is much more effective, auto sync, auto slant and auto select mode. If can't find in internet, you can download from http://amsat.org.ar/Setup_RXSSTV.exe 73, lu7abf, Pedro

voice on ISS

I heard in English "Romeo four" on the 145.800 downlink at the 1525 utc pass here. The pass was to the East so unless I demolish the house next door I have a very poor access in that direction. Think the voice was on top of the video but could not decode video. back in 104 minutes! 73 de andy g0sfj

I'd like to think that the recovery crew will drain the fluids and gases, and inert the rocket's propellant tanks *before* the welders start on those shoes - I for one would not want to be welding anywhere near a not-quite-empty and not yet inerted booster. 73 ZL2WRW Ross Whenmouth

Rig in for repair

I'll be off the birds for about 2 weeks while my 9100 is getting the ALC overshoot problem taken care of by icom techs. I wouldn't have bothered but I plan to begin to try some eme operation with an amp so I didn't want to risk frying the finals. I'll miss the birds! 73 Rick, W2JAZ -- Sent from Gmail Mobile
