I haven't read W8JI article, but if you are looking to process diversity data streams from two receivers, you might look at using Linrad. I am working on a project that uses the diversity function of the K3 with aux-Rx to process two signals that are opposite polarity in order to automatically align the receiver with the angle of polarization. The heavy lifting is done by Linrad. You can follow my progress at: http://www.kl7uw.com/LINRAD.htm

Very interesting. In the end of the day, it looks like some kind of voting system would be required to take the 'good bits' from each stream of data (antenna). At least with a mode like JT65a there is some hope of building that into the software - there's even two decoders built in, if the signal fails on the B decoder, the K decoder is tried - which is a voting system of sorts. I think the relevant bit of Joe Taylor's code is written in FORTRAN - so I'd better go and brush up on COMPLEX*16 variables. 73 Julian 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kw?, 144-1.4kw, 432-100w, 1296-60w, 3400-?
