[App_rpt-users] Simpleusb.conf Help

[Tim Sawyer]

RTCM transmit emphasis is automatically set depending if TX CTCSS is on or off in voter.conf. If PL is on audio is emphasized because it is assumed the audio injection point on your radio in not the mic input.

I assume you are not simulcasting because you wouldn’t want TX PL on one radio and not another in that environment. So what you need to do is setup another node for that one radio with low ctcsslevel to fake out pre-emphasis. 

[1998]
East = passwd1,transmit
West = passwd2,transmit
North = passwd3,transmit
South = passwd4,transmit
;txctcss = 79.7
;txctcsslevel = 100
;txtoctype = notone   

[1999]
OtherRTCM = passwd5,transmit
;txctcss = 79.7
txctcsslevel = 1
;txtoctype = notone   

Node 1998 has no PL and no pre-emphasis. Node 1999 has PL but so low it’s not there. It will also have pre-emphasis.

A new twist is that I need to NOT pre-emphasize audio going to one RTCM, but I *do* need to pre-emphasize audio going to another one. Can the file be split in a manner similar to usbradio.conf whereby one RTCM is fed pre-emphasized audio, and the others are not?
