OK,

I have been interested in receiving weather satellites and decoding for a while, and I have been even reasonable successful in doing so manually.

The setup I am using is as follows:

Discone-antenna -> Funcube Pro+ -> HDSDR -> Virtual Audio Cable -> WXtoImg.exe

And by manually tuning HDSDR to the frequency indicated by WXtoImg (at the right time) I can receive and decode the passes of the following satellites:

NOAA 15 on 137.6200 MHz FM is ON:
NOAA 16 on 137.6200 MHz FM is OFF: APT failed shortly after launch.
NOAA 17 on 137.5000 MHz FM is OFF: Decommissioned
NOAA 18 on 137.9125 MHz FM is ON:
NOAA 19 on 137.1000 MHz FM is ON:

And it decodes, and it will produce some nice pictures.

Now, all that is fine, but this way I have to manually tune HDSDR to the required frequency prior to a pass of NOAA 15/18/19.
I like to have this automated, hence I have two questions:

- how do I get the required frequency out of WXtoImg ?
- how do I set this frequency in HDSDR ?

so I am looking for some automated script/app, which can auto-tune the correct frequency in HDSDR as indicated by WXtoImg

Anyone have any idea ?

I apologize if this is the wrong forum; if so; please advice which forum is more appropriate if you can.

Thanks

No replies, but I think I solved my problem:

an application called "Orbitron" can control the frequency of HDSDR, including the doppler shift.

Thanks for the info, I received imagery from two of the NOAA birds this past weekend for the first time, pretty fun.

Thanks for the info, Edwin. I just received my first NOAA image as well and will try Orbitron to automate future receptions. I'm using an FCD Pro+ and SDR# - works FB.

Yes, get Orbitron integrated with SDR#, they work very well together. One caveat, make sure the downlink freq is set correctly in Orbitron, in my experience it is off sometimes. WXtoImg will show you the correct freq.

Using a 2M/440 J pole I'm getting pretty bad results but last night finally got a halfway decent image for some reason. I do plan on building a proper antenna for this, it is real fun.
