Hello Jim,

thank you for the quick response. I did try the new revision 569, but it
doesn't work. My config:

hdwtype=0
rxboost=1
rxctcssrelax=1
;txctcssdefault=71.9
rxctcssfreqs=67.0,71.9,74.4,77.0,79.7,82.5,85.4,88.5,91.5,94.8,97.4,100.0,10
3.5,107.2,110.9,114.8,118.8,123.0,127.3,131.8,136.5,141.3,146.2,151.4,156.7,
162.2,167.9,173.8,179.9,186.2,192.8,203.5,210.7,218.1,225.7,233.6,241.8,250.

3.5,107.2,110.9,114.8,118.8,123.0,127.3,131.8,136.5,141.3,146.2,151.4,156.7,
162.2,167.9,173.8,179.9,186.2,192.8,203.5,210.7,218.1,225.7,233.6,241.8,250.

rxctcssoverride=1
carrierfrom=dsp
ctcssfrom=dsp
rxdemod=flat
txprelim=yes

The repeater can be opened now without a subtone. Unfortunately subtones
will not be detected and regenerated by the repeater or simply passed
through the repeater. Any ideas?

Tnx,
73,
Jann
