WD9EWK on the next 3 AO-85 passes tonight...

by Patrick STODDARD (WD9EWK/VA7EWK)

Hi! Now that the weekend is here, I plan on trying the next 3 AO-85 passes from my back yard, and (for the latest pass) possibly the front yard. The middle of the 3 passes is almost directly overhead, and the latest pass - just before 0800 UTC - appears to cover Hawaii and parts of the southwestern USA. If anyone can be on AO-85 from Hawaii for that late pass (around 2200 local time in Hawaii), I will be happy to try working you from here in Arizona. The pass around 0800 UTC is up to 10 degrees maximum elevation on this end, but that should be sufficient if I operate from my west-facing driveway instead of my east-facing back yard. I'll have my SDR setup receiving all 3 passes, but may have the SDRplay on my VHF crossed dipole for the middle of the 3 passes. I plan on trying an HT with my Elk for that pass, and will have the SDRplay on the omnidirectional antenna running to collect telemetry and (hopefully) my signals from the HT through AO-85. 73!

SatPC32 and M2

by Jim White

Anyone successfully using SatPC32 to drive M2 rotors, the RC2800PX control boxes? Here both SatPC32 and SuM will move the AZ but not the EL.

Audio Coverage of Wednesdays ARISS Contact

by John Spasojevich

Please join us in listening to the ISS contact with participants at the Eleanor Palmer School, London, United Kingdom on Wednesday November 4th. AOS is anticipated at 09:51 UTC The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be a telebridge between NA1SS and VK6MJ in Western Australia. The contact is expected to be conducted in English. Audio from this contact will be fed into the: EchoLink *AMSAT* (101377) IRLP Node 9010 Discovery Reflector Streaming Audio at: https://sites.google.com/site/arissaudio/ Audio on Echolink & web stream is generally started around 20 minutes prior to the contact taking place so that you can hear some of the preparation that occurs. IRLP will begin just prior to the ground station call to the ISS. ** Contact times are approximate. If the ISS executes a reboost or other manoeuvre, the AOS (Acquisition Of Signal) time may alter by a few minutes ** 73, John - AG9D ARISS Audio Distribution Team

Re: [amsat-bb] No TLM on AO-85 during 20:15 UTC pass.

by Jerry Buxton

We will announce when AO-85 is commissioned and turned over to Operations for scheduled use. Meantime due to travel and work, it has been a little hit and miss on testing this week. Nothing has been said yet about any scheduled testing because it has been a matter of whether our people are home to test and if the satellite is in view of enough of us to gather data. I expect that we'll just continue that at least for tonight, so the satellite will be available but might just disappear into Data or Safe Mode during a U.S. pass... :-) If we go into Data Mode all who recognize that and can switch to and gather the high speed telemetry with FoxTelem are appreciated.

Re: [amsat-bb] No TLM on AO-85 during 20:15 UTC pass.

by Jerry Buxton

Hi Dave, We commanded into Data Mode during that pass, so what you heard was the high speed telemetry data and when you hear that again you can decode by switching FoxTelem to high speed on the input tab. AO-85 will switch back to Transponder Mode automatically after 15 minutes in Data Mode.

Re: [amsat-bb] No TLM on AO-85 during 20:15 UTC pass.

by Kevin Schuchmann

it was switched to high speed mode, if you switched over the eye would have come back and you would have gotten packets Kevin wa6fwf On 10/30/2015 1:35 PM, Dave Remnant wrote: > The TLM was making some strange noises and the "eye" was distorted and I > received no packets from AO-85 > > > > I could hear the transponder fine, but switching between the transponder > audio and the TLM shows the difference. > > > > I have video of this if any of the team are interested. > > > > Was this planned or is it something I may have done inadvertently? > > > > 73 de Dave M0SAT > > _______________________________________________ > Sent via AMSAT-BB(a)amsat.org.

No TLM on AO-85 during 20:15 UTC pass.

by Dave Remnant

The TLM was making some strange noises and the "eye" was distorted and I received no packets from AO-85 I could hear the transponder fine, but switching between the transponder audio and the TLM shows the difference. I have video of this if any of the team are interested. Was this planned or is it something I may have done inadvertently? 73 de Dave M0SAT

AO-85 frequencies

by Tom Worthington

I seem to get the best quality echo audio if I transmit on 435170 (at the satellite). The downlink doesn't seem to make much difference either for the audio or the telemetry decode but I use 145978 (at the satellite). I have not had a QSO but there are no others in Hawaii active now so I have only a short window to the western US. 73, Tom, NH6Y (BL10ts)
