Just to cheer up others with poor results - you're not alone :-)
FASTRAC downlink at 145.825: ISS + other QRM and clearly my 9k6 is not sensitive. Quite a few packets heard, nothing decoded. Here I (my station) clearly failed.
FASTRAC & O/OREOS downlink at 437: lot of QRM (50Hz humm, 50 KHz wide at 437.320)
O/OREOS: Yes I did hear it, 4 second packet period interfal, but I could not decode. Others (eg DK3WN) have better results. Seems 4 KHz above official freq, all the time, so I assume its not due to the keplerset (else that would not be 4 khz all the time ?) Your experiences ? Mike: what does your SDR analysis say wrt the frequency ?
O/OREOS keplerset: accepted by HRD (go to keplers, click add file (next to the list of URLs and upload the keplerset manually. But: I suspect it to be invalid, some programs do not accept the O/OREOS keplerset, HRD only accepted after I turned off the checksum check.
Anyway lot of new signals to hunt for. (and 145.825 will become VERY busy)
Looking forward to hear you results ! - Henk, PA3GUO (after a VERY short night)
Hi Henk,
no problems with O/OEROS decoding from our morning passes. You can see a lot of decoded packets on our SatBlog http://www.dk3wn.info/p/?p=18463
The satellite was minus 2 KHz from the calculated frequency by TLE on the mission dashboard website. I used SatPC32 for comparison only but tuned manually.
I could grab only a few packets on the afternoon passes.
73, Mike
