;------------------------------ JITTER BUFFER CONFIGURATION --------------------------
; jbenable = yes ; Enables the use of a jitterbuffer on the receiving side of an
; USBRADIO channel. Defaults to "no". An enabled jitterbuffer will
; be used only if the sending side can create and the receiving
; side can not accept jitter. The USBRADIO channel can't accept jitter,
; thus an enabled jitterbuffer on the receive USBRADIO side will always
; be used if the sending side can create jitter.
; jbmaxsize = 200 ; Max length of the jitterbuffer in milliseconds.
; jbresyncthreshold = 1000 ; Jump in the frame timestamps over which the jitterbuffer is
; resynchronized. Useful to improve the quality of the voice, with
; big jumps in/broken timestamps, usualy sent from exotic devices
; and programs. Defaults to 1000.
; jbimpl = fixed ; Jitterbuffer implementation, used on the receiving side of an USBRADIO
; channel. Two implementations are currenlty available - "fixed"
; (with size always equals to jbmax-size) and "adaptive" (with
; variable size, actually the new jb of IAX2). Defaults to fixed.
; jblog = no ; Enables jitterbuffer frame logging. Defaults to "no".

@Mike PL Filter shows up as enabled. I think it was like that by default.
@Chuck I didn't know that. I tried setting carrier to no and ctcssfrom to usbinvert but that did not work. Is there a particular way that would make it function properly?
Just to be clear, I tried usbradio but then moved back to simpleusb because of audio quality.
Thanks!
