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...

*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:
