Hello Dave,
   thanks. Glad that it worked ! I was fearing that my successful tests were only
a dream, caused by too much Chianti wine :-)
If you agree, I will produce a slowed down version to test on your 200 MHz PC,
also to check how the decoding worsens with respect to the faster version.
I suspect that many OMs still have PCs in the 166 - 200 MHz range, so a version
for this kind of PC could be appropriate.

For the Loran lines, in principle I could implement a logical filter, where you click
on the spur line, and that frequency will then be ignored by the decoding algorithm.
But this would not work if the spur frequency coincides with one of the slots....
I don't see an easy solution, but am open to suggestions.

Well, if you want to make a test transmission this evening, I will check that frequency.
But maybe a low power beacon would not make it to Italy... let me know please if
and when you will transmit, thanks.

Hi Rik,
   in this moment I am in my office at work, and don't have here an English dictionary,
so don't exactly know what a 'pock' is... but, as Steve Olney said, there always will
be some 'argue-naughty' around.. :-) But they are easily handled : just ignore them ...  ;-)

Your proposals look interesting, and, if someone will build the hardware, I am
willing to add this new interfacing mode. Just let's agree on the details.
