I will be attempting to detect CAPE-1 on the 3/27 08:01 UTC AOS in Alaska.
I plan a two-fold approach to detecting the cubesat: 1- Monitor CW with my FT-817 and Arrow out on my driveway (9.6 Kb FSK is inaudible except for slight quieting of the frequency). 2- Monitor 9.6 kb FM using my FT-847 and 11-elem M2 yagi (fixed on horizon) with input to my sound card and MixW2.
The first will be easy, though a bit coolish in single-digit temps at local midnight. The second I have not done since early AO-51 telemetry was watched. I need a tutor to help me set up MixW2. I will attempt to find those old instructions on the Amsat website if they still exist. A question is whether AO-51 9.6 Kb tlm mode is the same as the cubesat. I'm hoping to make a trial run on AO-51 to test my setup before next Monday night (0801 utc 3/27).
I have MixW2 installed and a audio cable that connects the 9600 packet output of my FT-847 to my sound card. MixW2 launches OK, but I have forgotten everything on running it.
The keps shown above are refused by my NOVA so I am not able to get accurate AOS predicted time and azimuth. Likewise, I do not know what to expect for Doppler on 435.245 MHz...I assume it will be high side at AOS. Nick Pugh, K5QXJ, is getting the AOS predicts for me, so any help on the rest is appreciated:
