Hi Simon,

Sure, with a little help from you:

1. Go to VFO mode
2. Set a frequency of, say, 146.0
3. Set deviation to wide
4. Store to memory 1
5. Change deviation to narrow
6. Store to memory 2
7. Download an image
8. Send the image to me

The channels don't have to be 1 and 2, but if they're not, tell me which 
ones they are so I know. I'll hopefully determine which bit is the 
narrow flag and add it to the code. It's important to make no changes 
other than toggling the wide/narrow flag between steps 4 and 6, 
otherwise it can be a lot harder to find the right bit.
