[amsat-bb] CAPE-2 CW over London

[g0mrf at aol.com]

Hi again.

For the ICOM IC706 in CW mode with internal preamp on:

The S4 reading equates to -117dBm
The S5 reading is -115dBm

6m of RG58 is 0.95dB at 145MHz

Antenna gain is about  +8dBi

Off pointing loss is about 2dB

Range for these signals was closer to 1500km

Have fun with the path loss equations.

Regards

David  G0MRF

Tnx David for the report
If you have a TNC we would like to get the AX.25 data. If you like we have ground station software. Do you have any idea how strong s-4 is in mv or dmb? Also what set of TLE are you using?

Hi Nick.

 

I've just loaded the latest set of keps for CAPE 2 and have managed to receive a signal at the first attempt from the right direction / frequency and time.

 

The pass was at 12.30UTC when the satellite was within range of London.

I was listening in USB to try and detect weak signals. However, not necessary as the signal was quite good (about 'S4')

 

CW at 12.32.   Frequency pulling as the CW was keying.  best freq 145.823

Then at 12.36 some stronger FM. (shame I was still in USB) Best frequency 145.822 (SSB)

 

As I'm at 51 degrees North the highest pass I see is about 17 degrees elevation.

The range today was about 1450km.

The satellite appeared to 'peak' a couple of minutes later than I expected.

 

4 element horizontal yagi pointed south and at 25 degrees elevation.  ICOM IC 706 with 6m of RG58 and no preamp.

 

I'll have a try at the next pass, but I can't find anything on the CAPE website which describes the sequence or timing of the transmissions. If you can send a link for this info and I'll be able to anticipate the timings and modes.

 

Thanks

Hi Roland
We thank you for the data. You are copying our sat better than we are. We
would like you to perhaps command our sat to do a data dump. If you have a
tnc we will send you the software to command a data dump.  I am also like to
know what type of antenna and receiver you are using and what the idle noise
when you point your antenna to cold sky.
 
Thanks
