I have a very good S band amplifier.FLL177 has 30 db output in 2.4 G.I think FLL357 should also have 30 db
From where could we get this amplifier

i was trying with sdrplay, but it does not detect , any idea. The software does detect RTL SDR

@Marcel, thanks for the update. Could you provide details about your test FTA channel details(SCPC type), if the satellite(footprint) is over India i could try

Hi, just fixing the last 8PSK problems. Next release will probably be on thursday.
Hello
It appears you are trying to decode a commercial DVB-S2 free to air channel , hope it would be very interesting

thanks everyone, able to get the beacon temporarily, Minitouner is excellent.
Appears my dish has physical damage after thrown away by strong wind, the focus has shifted. if i change the focus by bending the LNB support rod, i am getting >5 db C/N, if left unforced the C/N is coming around 1.9-2.5 dB

Thanks @DD0KP for your help. I have Minitouner Express(i got one when i was in USA this April) and software. I have set it up already. What i understand, i have messed a bit in my dish/lnb setup.

The bandwidth is 2.4 Mhz .
with 12 V via Bias Tee
with 18 V via Bias Tee
The SSB signal is not getting reduced when applied 18V, in fact signal is getting boosted.
I have not applied skew angle (for my location in Bangalore ,it is 73 deg). Probably
1: i need to manually rotate the LNB and find the point of maximum and minimum signal. The minimum SSB signal point can be H . Probably voltage switching is not effective or as i have not put skew angle (i have set to 0 deg ) as required , the result is non -reception of DVB signal.
I have SDRPLAY RSP2/RSP1A,PLUTO SDR and Minitouner, but without proper setting SDR would not much of help. Let me manually rotate to find V,H settings and then look for spectrum in wide band using SDRPLAY or Pluto SDR.

Hello
Good day to all. I have been receiving SSB(NB) voice from QO-100 but unable to receive DVB-S2 signal.
My Setup
--------------
1: SDR#/SDR Console
2: 65 CM DTH DISH (offset)
3: RTL SDR BLOG V3/SDRPLAY RSP 1A
4: Bias Tee
5: USB to 12 V DC-DC boost cable
6: 19 V Laptop Power Adapter
(One for V and other for H modulation switching)
7: Connectors
8: LNB 40 dB,LNB 70 dB
9: Generic DVB-S2 Receiver KOQIT Mini
10: MiniTouner Express
11: My location is Bangalore, India
Azimuth
260 Deg
Elevation
30 Deg
Skew
73 Deg
The SSB voice reception is good but i am unable to see DVB-S2 spectrum on the SDR program(while using SDRPLAY RSP1A).
The polarization switching is done by feeding 19 V to LNB via bias tee. Even after feeding 19 V , i could see only NB signal not WB signal. I tried HW and sw decode (leandvb@pabr,DVB-S GUI@Marko) of DVB signal (though it does not make sense)
I am not sure what i am doing wrong. Could some one help.
Best Regards
