can we get two defaulted images from some 7800's and 7900's. I have a 7900, so i can provide at least one.
Suspicion is that there might be a very slight radio image difference, as there is purported to be a feature where you can put 7900 into memory only mode.. Wondering if doing this changes any bytes in the image?
Also, I'd like to see if the few bytes after id (AH015) are indeed sub-model specific, as I have seen those change when one fools with configuration diodes such as US vs EU (and - cough - widebander mods...). Perhaps there could be a slight difference here also.
Sidebar observations: In fact, yaesu is very odd with this on some of their HTs. You can do a mod, reset, and the bytes will change. Old image (without modifying those bytes) will fail upload. However, what is interesting is, that if you dont reset, the previous image will continue to run (and radio will use that software configuration, despite hardware diode config). i.e., you can do the following: 1. do the hw mod and reset 2. download the new, empty image, populate channels, and reupload 3. undo the hw mod, but dont reset 4. your mod stays until you upload again (which requires the unmodded bytes configuration to succeed)
its almost as if the hw diodes are only used for defaulting the image and rx'ing an uploaded image.

Yaesus transfer so much extra stuff during the clone... there's got to be a blob of static data we can use to differentiate the two radios.
Seriously, look at the images. It's been a while since I looked, but I couldn't find anything. I was able to write the 7900 image into my 7900 without any problem.
