Lee, good stuff, thank you! I may have to investigate a different audio path on my radio, detector audio may not be the best choice for my application, but may be my only option.

Hi Stephen,

Have a read through http://wiki.allstarlink.org/wiki/RTCM_Client#Receiver_De-emphasis  (and some of the other info that is there) and see if it answers your questions.


Cheers!

I'm going to be deploying a dedicated 900Mhz simplex node soon using an RTCM. I will need de-empasis set, as I will be pulling my audio directly from a discriminator, but I am little unclear as to what the defaults are for de-emphasis. 

For example, I see this in the RTCM manual: 

[5678] 
buflen=750 
mobile1 = mobp1,adpcm,transmit,nodeemp 

If I just simply leave out "nodeemp" will that perform de-emphasis by default? 

Waiting on parts to be delivered so I am unable to test anything myself just yet, but just curious if someone has already ran into this and could clarify for me.
