You guys probably already know this, but I found some info on Metop-A here: http://www.wmo-sat.info/oscar/satellites/view/306 Service Dir Frequency Emission designator Bandwidth Polarisation D/A Data rate or Baseband Comments ADCS S-E 465.9875 MHz 1K00G1D 1 kHz RHCP D 0.2/0.4 kbps DCP configuration control If you can analyze the signal and determine if the bandwidth is approximately 1kHz and the data rate is close to 200 or 400 bps, you may be able to confirm or eliminate metop-a from consideration. If you have a RHCP antenna, you could also check to see if the deep fading you mentioned goes away. -- David Tiller Lead Consultant/Architect | CapTech (804) 304-0638 | dtiller_at_captechconsulting.com ________________________________________ From: Seesat-l <seesat-l-bounces+dtiller=captechconsulting.com_at_satobs.org> on behalf of Satcom via Seesat-l <seesat-l_at_satobs.org> Sent: Wednesday, February 10, 2016 2:51 AM To: seesat-l_at_satobs.org Subject: Re: Fwd: Re: Confirmed KMS-4 Radio Reception on UHF If it does turn out to be Metop-A , its an understandable mistake Scott. Better to have tried and failed than failed to try! Plus it helps others to illiminate possible contenders.
