Ryan and all,
Thank to all of you who gave me hints and advices.
Finally I found a solution, HDSDR to explain:
1) With HDSDR one may set the output sampling rate and radio bandwidth. unfortunately cannot switch off the de-emphasis on FM which would have been then perfect for telemetry reception. The workaround is proper setting of bandwidth and volume. 2) Made a few test today and all seems to work OK automatically for the following birds, NOAA’s, AO-73, AO-85 (therefore all the Fox birds), CAS-4A & 4B, therefore switching well automatically between the birds without any OM intervention. Need to test more for other birds. The intention is to have automated telemetry reporting for a maximum of Birds.
All these SDR software have their advantages or disadvantages in a particular situation or hardware setup. I tested some of them such as SDRSharp, SDRconsole, SDRuno and now HDSDR with both RTLSDR and SDRplay 2. There is no magic tool but compromise for the application one want to implement.
The BB is a nice tool to share experience and knowledge, thanks to the organizers.

Jean Marc,
I have the same issue with SDRConsole, I placed a message in the groups.io http://groups.io/ forum for SDRConsole asking for a way to modify whether NFM or WFM is selected by CAT control, but the author has not responded to it. It would be good if you could join that group and reply that it's a problem for you as well so that possibly we'll get some more traction from him.

I am trying to fully automate telemetry collect on many birds, my issue is that I cannot get the SDR mode right, in a nutshell:
- I use SATPC32 which fully control simultaneously the TS-2000x and SDRconsole or SDRuno fine with a SDRplay RSP2 for frequency and doppler, the rotors also no issue also. More SATPC32 automatically switches between Satellites which is perfect.
- I can decode most of the telemetries using softwares such as Foxtelem, DK3WN and having different sound modems all in parallel, also no issue at all.
My only issue is to have the SDR on the right mode particularly WFM for most of the birds, as each time it goes to NFM which is not suitable.
Has anyone tried same? If so what may be a possible solution to be able to automate the station for automatic telemetry decoding?
Thanks for any suggestion and help.
