What do you get from the difference in the files? What should I try next?

Wow, lots of differences! If you leave the VFO and settings how they were
the first time, you don't have to worry about tracking changes there too.
It sounds like you changed the VFO to 150, and stored a memory in channel
1. This makes for twice as many differences to sort out.

I'm going to guess your VFO was set to 140M the first time...
< 0000170 0000 0000 0300 0000 0c00 0000 4014 0000
> 0000170 0000 0000 0000 0000 0c00 0000 0015 0000

*If* that's a frequency and not some other random data, it can be read in
Chirp like this:
#seekto 0x17D;
bcd freq[3];

There's also stuff that looks like 150M in two other places, so you have
some more sleuthing to do to figure out what is what:
