Using "Virtual PC" software on a Macintosh?
We may be moving into stuff the general readership isn''t much interested in, so feel free to contact me directly if this doesn''t help, OK?
When you say things are working well for the G3 when running Vis Nav Suite, I take that to mean that software is seeing your GPS NMEA data as when it''s ported to the laptop. The Nav Suite should require you to designate a comm port so it will know where to look for that data...which comm port is it? Now have you gone to Tools/Options/Connection in Airmail and insured that you are designating the same comm port, assuming that you unplug the GPS input cable and connect up the TNC cable? Given the above, that should work for you. However, if your nav sofware is running under the Mac OS, then the Comm Port # may be different when emulating Windows...have you ID''d with certainty which Comm Port you are actually using when running in emulation mode?
If all this doesn''t fix things, review the other settings in Airmail to insure they are correct (e.g. do you have a SCS PTC II or IIPro? set ''Direct using Control Port'' and so on). And a big issue I didn''t ask you about last time: are you using an SCS TNC or a Kamtronics? My comments assume SCS.
Assuming proper settings but no success, that leaves me suspicious about the pin-out of the cable hfradio provided. Did they (or Keyspan) provide you with a pin-out? Check it for accurate construction by doing a continuity check with a VOM.
Our Mac laptop is a G3...but you are beginning to stumble into the reason we stopped using it on the boat and switched over to PCs. Macs for all their benefits are usually on the outside, looking in, when it comes to running marine applications and their owners enjoying the help of other marine users trying to do similar things. As I think I said in an earlier post, the desire to stay with a Mac because of ease of use and familiarity became eroded over time - for us - because it actually became harder to use, while the Windows software slowly evolved into making a PC easier to use.
For a Caribbean cruise, we ended up using a PC as the primary laptop and kept the G3 as a back-up (which at one point was needed)...but of course, the G3 can''t use emulation software to run graphics-intensive stuff. Still, it was great to remain capable of doing email and wx downloads via Winlink. You might consider a similar possibility. It was only when prepping for an Atlantic crossing that we realized the back-up had to be fully functional, as well.
