I don't have an FT1D to test with only a VX-8DR, but I would be interested to see if these bits can be back ported to the VX-8(D).
For the most part I tried to keep the names of the structure members the same even if I juggled the order so my changes "should" work with the VX-8 driver.
One hitch is that the memory layout for the APRS data is different on the original non-D VX-8, and the D version (VX-8D[RE]) due to storing 50 beacons vs. 40. It looks like the FT1D stores 60 beacons so it will also be different. It's been a while since I looked but I think the reason I didn't try to add the APRS beacons/messages to the memory structure definitions was not knowing how to handle the layout differences between the non-D and D in the same driver.
There is some code in the VX-8 driver to account for the varied number of records that I partially pulled into the FT1D driver. I didn't understand the code well enough to add an additional offset for the APRS messages.
What I did find was the layout of each record differed slightly in the FT1d from what was in the VX-8D.
