I definitely don't really understand what I am doing. I am more of a
software guy. Prior to resampling I alread
I am writing a GR C++ program I would like to do a simple rate resampling
and I don't need to use any FIR filters. Is there a Null Tap or a pass
through filter I could use? Would some form of this work?

std::vector(1,0));

I am working on a processing multiple signals using a single source block.
The background is below, but I had a couple of high level questions:
- What is the best approach performance wise for selecting multiple ~15khz
channels from a 2mhz+ source block? Is it using a Xlating FIR Filter with a

Thanks Nick, will do!
In case other people have Moto Smartnet systems with analog voice channels,
I have my code up here: https://github.com/robotastic/gr-smartnet
It is Nick's code with some of the patches from Reddit added in. It works
with GR 3.6.5.1 and RTL-SDR. I also added in IF/BB gain opt
In DC the fire dept uses a Motorola SmartZone II trunking system and most
of the talk groups use digital voice. I have gotten Nick Foster's
GR-Smartnet code up and running and I am able to decode the trunking
channel and record the NBFM version of the the Digital Voice in the talk
groups. It manage
