Hi there,
I have an 8900, and I'd like to program the 6m and 2m repeaters in our local area using what Yaesu calls "Narrow FM" - 12.5khz deviation. Unfortunately Chirp only seems to support FM and AM for this rig (checked using the latest build, and confirmed according to the support statement athttp://trac.chirp.danplanet.com/chirp_daily/daily-08202011/Model_Support.htm...). Is there any way NFM could be added so that we can save repeaters with narrow FM set? I believe that this should be possible with the image interface - when cloning between two rigs a while ago, I had a couple of repeaters that were set to narrow FM and they cloned in just fine...
Many thanks,
-simon

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.
Thanks!
Awesome, I will try to do this tomorrow morning before we head off on holiday. Out of interest, is the binary format used by yaesu for the 8900 documented anywhere? Do you have any reverse engineering notes?
Cheers,

By me? No, not really, other than in the code. The 8900 driver is the same as the one for the 8800, 7800, etc, so it's not as straightforward as some of the others. However, you can view the code and the memory format definition here:
http://d-rats.com/hg/hgwebdir.cgi/chirp.hg/file/24bd89cc0959/chirp/ft7800.py
If you'd like do discuss further, lets take it to the chirp_devel list.
Thanks!
