[chirp_devel] (no subject) KG-UV8E

[Pavel Milanes]

Hi Derek

I have cleaned the data in the serial logs uploaded by the users and 
It's pretty similar to the communications flow and meaning described in 
the KG-UV8D plus, I will try to figure out if the encryption is the same 
and will poke it to see if I can get it decrypted.

It makes some logic that they reused the same algorithm, and even the 
same key for the xor encryption. I will see.

[few hours later... I think I hit "send" but apparently not...]

So far so good, I have built a simple validation script for individual 
packets and decryption seems to work, they match in the payload size and 
checksum, I will try the hole data file and try to figure some logic 
from it.

If they changed the single char encryption I think that a loop for the 
256 available chars and some intuition looking at the data must figure 
it out.

I have to go offline now, will be back with results tomorrow.
