I'll leave Wouter out of this reply since I know he's overwhelmed with  
stuff right now.

I've got both an ICOM IC-910H and an ICOM IC-R1500 receiver. I'm  
tempted to just use the R1500 because it shows up as a USB Audio  
Device when I plug it in to my Mac, making it much easier to record  
from. Oh, and it's very portable, which the IC-910H is not. I plan to  
drive up to a high spot on Crestview in San Carlos (Belmont?) and  
point my antenna and do Doppler correction by hand (sadly, I don't  
think MacDoppler Pro can tune the R1500 yet).

I think the receiver in the IC-910H is better than the R1500, but it's  
just going to be so hard to lug up there, and I don't have a cable to  
record its audio. I have time to make one, so I probably should, but  
I've got a mental block for some reason.

Maybe someone with more experience can tell me what I should do instead.
