Version mix up of Raspbian and Debain package

[rfamp]

Hi,
I'm stuck at a rather strange problem regarding an installation on raspbian and plain debain 10:

On raspbian I have rtl-sdr 0.5.3-11 installed which features the udp frequency retuning option by opening an udp socket.
On my Debian 10 machine I have version 0.6.1 installed which does not feature this option. So are these packages from different repos or git branches? And how can I get the udp functionality on my Debian 10 machine?

I tried to look for any answers but I'm unable to find the sourcecode/changelog of the raspbian version which features the udp socket.

Regards
Joshua
