[App_rpt-users] ctcss Encode Issues

A follow up to my previous email:

I have multiple ctcss tone frequencies in usbradio.conf.  app_rpt is
decoding the incoming CTCSS (confirmed using debug), and it transmits CTCSS
while someone is actively keying the repeater.  However, as soon as they
release PTT, app_rpt stops transmitting the corresponding CTCSS tone that
was being used, and reverts to the default tone instead.

So, if I key the repeater using 146.2, it broadcasts out using 146.2 and
other radios hear audio just fine.  But, as soon as I release PTT on the
mobile/portable radio, the squelch tail is broadcast using 151.4, not
146.2.  This results in the users programmed with 146.2 not hearing the
courtesy tone or squelch tail.

Has anyone else run in to this issue?

Here's my usbradio.conf file again:

[usb]

hdwtype=0
rxboost=1
txboost=1
rxctcssrelax=1
txctcssdefault=151.4
rxctcssfreqs=146.2,141.3,151.4
txctcssfreqs=146.2,141.3,151.4
;rxctcssoverride=0
carrierfrom=usb
ctcssfrom=dsp
rxdemod=flat
txprelim=yes
txlimonly=no
txtoctype=phase
txmixa=composite
txmixb=0
invertptt=0
duplex=1
rxondelay=0
rxnoisefiltype=0
eeprom=0
