APRS + 48000 sample rate

 

Hi,

I plan to use Direwolf with a DRA-45 for an APRS station. I'm wondering if 1200bps / APRS would benefit from a 48k sample rate versus 44.1k. I set the flag (-r 48000) on 1.7 B (Oct 26 2021) and it warned me:

Calculated pre filter size of 417 is too large.
Decrease the audio sample rate or increase the decimation factor or
recompile the application with MAX_FILTER_SIZE larger than 404.
I'm going to recompile either way to get rid of the?IL2P header message but will just leave the MAX_FILTER_SIZE?alone if it won't make any difference. I'm not sure how one would "increase the decimation factor" if that is an easier approach.

Thanks!

Jason
