Hi Joe... Very interesting. I did not know this about VSPE. Seems to work very well with the apps and hardware I have. In fact, my setup is a Yaesu Ft5000 sending com port data to DX4WIN, N1MM and SpecraVue all at the same time with no hiccups. My FT847 is also connected and N1MM directly accesses that (SO2R) and I can turn it on with DX4WIN manually of course. But everyone seems to be happy. (knock on wood)
Thank you for enlightening me on the inner workings of each app. 73 Al N9ISN On Thu, 05 Apr 2012 10:08:38 -0400, "Joe Subich, W4TV" <li...@subich.com> wrote: > >> Works the same way as the microHAM router software without the need >> to get the microHAM interface.
