Hi Alan,
I gather you are running the latest FreeDV GUI?
Nice that you have it compiling. The integration side is only partially
done, so you've running a work in progress!
Yesterday I found an issue with that was causing the FreeDV 1600 modem
to lose sync occasionally, so have gone back to fix that.
Cheers,
David

Hi,
I've just compiled Ver 3553 on my Fedora 23 x86_64 box and note

Also when running I get a lot of Overrun messages:

ALSA lib pcm.c:7963:(snd_pcm_recover) underrun occurred

I've fiddled with Samplerate , 44100 then 48000 then 32000, not much
different.
My box is a Low Power motherboard, ASRock QC5000-ITX, the AMD Kabini
processor with graphics.
Soundcard: Behringer UCA202 USB
All I need is a signal on 14.177MHz
No 73 valve here, only a 6BK4.
