Noted Kevin, so my putting the radio in 9600 data mode the audio is now available from the discriminator directly. For some reason I am unable to decode the telemetry from AO85 and AO91 using a ICOM 821H and Signalink USB. Will try soon with an SDR as well. 73 Nitin [VU3TYG]

I will mention that for a Icom IC-9100 you need it in Data 9600 mode, the reason being that 9600 gives you the full bandwidth, in non-data mode the radio filters out the sub-audible tones.

Hi all, Today 21st November 2017 is a 4th birthday for FUNcube-1 ( AO- 73 ) since its launch in the year 2013. "Congratulations and HAPPY BIRTHDAY " The satellite has been a key player for me not only with many contacts, but also for its role in demonstrations,exhibitions and STEM related work.
I therefore offer my thanks and appreciation to all that have been involved in the project including radio amateurs for the contacts. Their valuable time and effort, dedication and work, has been an inspiration for our hobby and education. Likewise may I also offer my congratulations to the FOX - RadFX (AO-91) project and launch teams on the recent success.
Indeed many projects have or will be key players in our hobby. A big "THANKYOU" - Long may they continue as partners in our hobby and studies in science and technology. Ken Eaton GW1FKY

I have a python script that emulates a simple hamlib server (which does some conversion to control SDRSharp) that GPredict can use.
you can find it here:
https://www.dropbox.com/sh/5v6x87kv4kq02g7/AAANexHJ6L4MgCRalXkOq5wta?dl=0
It has lots of comments and should be clear how it works.
Should run on Windows or Linux (careful on Linux with newlines, you may have to copy-paste into a new document to get the formatting to line up)
I use it all of the time running Gpredict and this script on a Raspberry pi which then controls SDRSharp running on a Windows 10 machine elsewhere on my small network.
cheers, Graham ve3gtc

Hello
I would like to write a perl script to eventually graph the doppler shift of ISS, Falconsat and Fox1-B over time using LINUX
Has anyone a script that can act as a server that gpredict can connect to and would spit out data ?
I just used netcat and saw data
Just curious someone might have already done this ?

SAT Gridders,
TNX for all the Q's last night from EM67/68. Tonight, I'll be in northern MS, then to northern LA until after Thanksgiving. My return route to the home QTH will be similar. Operation will be strictly Holiday-Style (HIHI). QSOs will be uploaded to LoTW when we get back in EN91 the first week of December.
Also, TNX to KG5CCI for posting the SO50 pass recording from last night on Twitter! It was the first time my XYL was able to actually hear one of my Rover activations as if it was happening real time. Previously, she had only heard the noisey & garbled audio from my little digital recorder. :o)
73, Bob - K8BL (AMSAT #6593 since 1979)

What is a good computer interface that will handle 9k6 audio bandwidth? Mike K4MIA
Mike:
I can confirm that the Signalink will not pass 9600 baud signals out of the box. The tech at Tigertronics told me that some have modified the unit to work 9600 baud packet, but didn't have any further details. I suspect the mod has to do with bypassing the audio transformers.
Another approach would be to use your PC's sound card along with UZ7HO's full-duplex Soundmodem. I've had great success working Falconsat using this setup with a cheap StarTech USB sound card. Scott's, K4DKR, plug-n-play PTT works well with this setup.
If your intention is to work Falconsat, you'll need a virtual serial port to link Wisp with the UZ7HO's Soundmodem. Let me know if you need further details.

Using my USB, FT 847, HS_soundmodem, and UISS, I have had success making contact with WD9EWK, and KK6OTJ on one FalconSat pass. (PFS3-1)
no modification to the USB (except to wire it for the pin 4 (9k6 on the radio dataport)). With this setup I can also connect with a local 9k6 packet node.
caveat: for transmitting, connection success to the node is not consistent, and for Falconsat very few hams are on for successive testing. (probably need to learn WISP for next step.)
For receive with this setup it decodes with no problem from what I can tell on all passes.
73 Christy KB6LTY - Happy Thanksgiving All!
