If it were me, I'd just use the DSP and let it do the PL processing.
In fact that's what I do on all our nodes.  With no complains.
Heck it can even do reverse burst on encode.

I'm not sure about the newer Com Spec decks, the the TS-32 had a high pass filter on board.

Subject: [App_rpt-users] Passing CTCSS / PL Tone Over The Network

Can anyone help me with eliminating passing CTCSS / PL tone from a receiver discriminator onto the network?
I am using an URIx FOB with external ComSpec CTCSS / PL decoder and squelch gate COR.
The 167.9 Hz CTCSS / PL tone is really noticeable while listening using IAXRPT and occupies 50% of the green bar graph.
I realize adding a High Pass or Notch filter would help but is there a configuration setting change that will eliminate the tone?
Thank you,
Chris Hill
