[App_rpt-users] fighting echo within the soundcard.

[Don Russell]

I am building a new node from scratch.
atom pc, uri-x, 2 SM50's.. nothing fancy.

I am getting a 1/2 second echo, like
you have another radio on in the room.

I did the normal tuneup.
got these parameters.
rxmixerset=125
txmixaset=400
txmixbset=0
rxvoiceadj=2.725307
rxctcssadj=4.019996
txctcssadj=300
rxsquelchadj=850

I tried with/without the rxboost. no change.
I have battled this in the past and I just
don't remember what the fix was. It's been a
2 years since I have had a node up. trying to
get back in the swing of things again.

I did bring up alsamixer, the card looks good, mic is not in playback mix.
