Hi Steve
yep
It didnt take long to find, a few minutes , since, well it seems modems
all have the same type of bugs... if you design modems long enough and I
guess you can sniff with your nose the usual bugs !
I was just wondering if the usual code maintainers were going to take it
on ?
Or I can fix it over the weekend. either way, I wasnt sure how things
worked here...
cheers

I think the theory is, you send a BPSK value (in this case 0:0 or BPSK
1.0 + 0.0j
Then on receive it should be the same value, or it is out of sync, or
it is garbled by the ether.
The value is not really important, just that it be the same BPSK
value, which the decodes to two indexes of the bits rx_uw of value 0:0

Excellent Alan !
right, like I thought , tx_uw always zeros , and rx_uw goes to
zero because input level falls.
OK David, I am sure you had other ideas in mind for tx_uw ?
that is it has been initialized to zero and never set..
