Ok, 

Slightly modified SM1000 code. Basically all menu functions removed so
it only powers up in DV mode. 

GPIO pins changed to a few different pins and DAC1/2 transposed. 

ADC's have not been changed because there is no easy way of doing that. 

Appears to modulate fine. 

Decode/RX has a good solid RT LED but anywhere from 3-20 seconds after
RT light coming on during a receive of a good signal. (ie this mornings
broadcast) The ERR LED stars flashing frantically like almost solid on. 

Audio becomes garbage. 

25% of the time it will recover after 10-20 seconds other times I get
frustrated and need to PTT, power cycle or hit the reset. 

Then it is almost instantly up and running fine again. 

I noticed this originally when running audio from the PC directly into
the modem and thought it may be because the computer is glitching as its
quite a slow computer. 

I expect glitches to happen but I am not sure on causes of lack of
recovery. 

Have tested at various levels and this does not seem to effect it. 

Any thoughts? 

Or has any one seen this before? 

Cheers 

Eric
