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:
My lat=60.675N, lon=151.316W, AST=UTC-8

Ed --
Thanks for your commitment and planning to receive CubeSat CAPE-1 during your first pass after launch on 27Mar. The CAPE-1 team will be very anxious to receive your report immediately after the pass. A few thoughts that come to mind:
-- 9600bps G3RUH FSK modulation can be easily detected by ear when using SSB/CW receive mode.
-- I note that your first pass will be at ~57d elevation at TCA. This will be out of your Yagi main beam width but elevation before and after TCA will be useful.
-- Both CAPE-1 and AO-51 transmit standard 9600bps G3RUH FSK AX.25 telemetry packets so your previous success receiving AO-51 telemetry is encouraging. I have no experience with MixW2 to share but we will be interested in hearing about your success using MixW2 for CAPE-1 telemetry.
-- Preliminary TLEs manually load to GrafTrak AOK and predict the correct track. I am not familiar with NOVA but perhaps it also has a manual entry facility(?) This is what I get from GrafTrak for your coordinates (assuming a nominal launch):
AOS 08:01:35UT AZ 175 EL 0 435.255 TCA 08:08:58UT AZ 259 EL 57 435.245 LOS 08:16:16UT AZ 343 EL 0 435.235
If you are not successful with manually loading preliminary TLEs to NOVA I will send a tracking table.
-- You may also be successful receiving 1200bps AX.25 telemetry from LIBERTAD-1 on 437.405MHz or at least be able to report that it has been heard.
