[amsat-bb] Satellite Connection

[Rupert Hamblin]

Hi All,

Thought I would update on my current situation, having been through a 
few "hoops" to get to where I am now !

So the bottom line is, thankfully, I am now active on the SATS and have 
nearly a dozen QSO's in the log..!

Following up the comments below, I did a number of things to the 
stations to finally get working, these included,
setting the correct CTCSS tones on the 847, realigning the azimuth on 
the rotator, it was around 20 degress out - all
of which helped....but the biggest impact was the 847, its been in for 
repair under warrenty twice now, thankfully,
so far all looks ok now. Two issues were identified:

Frequency and control error on VHF/UHF bands, a couple of chips were 
replaced, and the killer one was, whenever I
switched to SAT mode, the TX output would drop to nearly zero on UHF, 
whilst on VHF power was also reduced and
the CTCSS tones were corrupted.....apparently from the dealer repair I 
was told both issues were known problems.

Thankfully, all now resolved - and up and running....!

As I finally get my head round the station / Doppler / SatPC32, I may 
post a couple more queries....thanks for your
tips and advice here...!

Cheers RH / G0TKZ
