openMD9600 SATELLITE
Re: openMD9600 SATELLITE
Hi there Jack
Yes i have had a contact via ISS FM repeater, everything there is working 100% using a little groundplane in 4m high but didnt have any problems with the signals or frq trascing it works ...

Satellite mode definitely works.
N1ID tested it for several months to multiple different satellites, not just the ISS.

Yes I have used it on the two MD9600's I have. (V2 and V5) I have made contacts on ISS and AO-91.

Hello, I used my tyt9600 for satellites, but there is a frequency shift of at least 3khz minimum.
However, the frequency is well updated on the screen of the tyt9600 compared to two satellite tracking software (the 3 indicate the same rx/tx frequency and the same elevation/azimuth).
I have the latest version for v2.1
Do you have an idea?

Re: openMD9600 SATELLITE
Probably the satellite is not at its predected position. If you are using the ISS, it often adjusts its orbit to avoid debris, and the Keps data published by AMSAT and other organisations is not always 100% accurate.f4igg wrote: ↑Thu May 18, 2023 8:25 pmHello, I used my tyt9600 for satellites, but there is a frequency shift of at least 3khz minimum.

Sometimes if you try using Keps from another source, the data can be more accurate.
Please post to a specialist satellite forum about this
Re: openMD9600 SATELLITE
Right. When there is conflicting data you don't know which organization is up to date, and it's not always the same one.
I've been using the Keps data from the AMSAT daily bulletin file https://www.amsat.org/tle/current/daily-bulletin.txt for the last several months and have been pleased with its accuracy for the ISS. When it differs from my phone app which uses CelesTrak data the phone app is usually wrong.
To use the daily bulletin I made a simple powershell script which does the following:
- downloads today's bulletin file
- saves an unmodified copy with today's date prepended to the file name
- blindly chops off the first 20 and last 3 lines
- saves the modified data to a file named dailykeps.txt
dailykeps.txt is ready for use by OpenGD77 CPS.
Code: Select all
$file = (Get-Date -Format "yyyy-MM-dd") + "_daily-bulletin.txt"
Invoke-WebRequest -Uri https://www.amsat.org/tle/current/daily-bulletin.txt -OutFile $file
$tle = Get-Content -Path $file
$tle[21..($tle.count-3)] | Set-Content -Path dailykeps.txt
