HitSat not heard
by Edward Chuang 24 Sep '06

24 Sep '06

I couldn't hear anything (CW or packet) from HitSat during UTC 09:10 and 10:44 passes Sep. 24. (PL04vq) My set up should be no problem, because I picked up a piece of CW tone from HitSat yesterday even when the elevation angle was as low as 3 degrees. 73 Edward / BX1AD -----

HITSAT reception
by Andythomas 23 Sep '06

23 Sep '06

Just to confirm my reception earlier this eveing of a fragment of trlrmrtry. I have a very basic setup here - this should inspire people to listen out for these cubesats. I have only a AOR8000 hand/held scanner for cw at 70cm and I built my own 70cm RHCP 6 ele yagi (no preamp). I predicted the az and el of the pass using object A keps and at 17:38:25 utc on 437.8125 CW (and dopplering down) recorded a .wav file to transcribe later as: 0d4d4f (maybe "g") 46f 84c This compares well with more competent reports (DK3WN)!! The cw decode from the Hitsat website gives me: Element set decode received EE temp. w face 0d DD temp w face 4d GG temp x face 4f HH temp x face II temp y face JJ temp y face KK TX temp LL battery temp 4c Don't know what units these elements are in though. So there we are, modest equipment, can read the housekeeping data from Hitsat! I've sent a WAV file to the command team, if they can make sense of it. andy g0sfj

RS-15 satellite.
by Garyatlnt＠aol.com 23 Sep '06

23 Sep '06

I was reading recently about the status of RS-15 which was declared semi-operational. Nevertheless I thought I would give it a try. I would sporadically hear the beacon and then try to access the transponder and remained persistant in trying for several days, then about 3 days ago I turned on my rig to try and forgot the uplink frequency and wrongly entered 144.958 to 144.998 [rather than the listed uplink of 144.858 to 144.898] and the transponder responded with the downlink still in the listed range of 29.354-29.394. I have continued to be able to get the transponder to respond by useing the "wrong" uplink of 144.958-144.998. I hope others will try the same as I sure would like to make some contacts rather than simply hearing my own signal. Thanks. Gary DeMunbrun [ WA4RKS].

CW decoder for Linux? [was HITSAT CW]
by John Mock KD6PAG 23 Sep '06

23 Sep '06

Anyone know of a good adaptive CW decoder for a Linux? The one i'm familiar is fairly old and operates at a fixed speed, which isn't so good if one wants to set things up to receive several satellites and especially if one doesn't know the CW rate in advance. I hacked something like this into one of the PSK31 programs (intended for hand-sent CW), but the original source has changed substantially since then and is graphically oriented (which isn't very useful for telemetry). -- KD6PAG (Networking Old-Timer, Satellite QRPer) [Note: If i'm in your address book, please replace 'qsl.net' with 'amsat.org'.]
