Re: Lime Mini shoulders ?

I am using a Tandberg EN8090 H264/AVC High Definition Encoder (I work in the cable TV world ...) of which I use the IP Streamer Output.
The bitrate mode is set to CBR, the bitrate is equal to the TX Bitrate set on the DATV Express interface.
The PC is an i5-6402P CPU @2.8GHz. This works very well.
The spectrum of the Mini Lime SDR when using DATV Express is very good. Shoulders better than 50dB.
I also use the portsdown 2019 with a RPI3B+ and Mini Lime SDR, also in combination with the Tandberg EN8090. The hardware encoding is just perfect.
One can even make HD with this combination. The only thing that bothers me about the RPI - Mini Lime SDR combination are the shoulders when using SR>500Ksps.
So, I only use the IPTSIN. Is it not possible to slim down the software so that the 4x oversampling is possible up to for example 1 or 2 Msps ?
