CHIRP

I have just bought a KT8900 from Aliexpress https://www.aliexpress.com/item/1005002504842825.html?spm=a2g0s.9042311.0.0.27424c4dsiIlC2 and found that it was not recognised by CHIRP.
Modifying btech.py solved the issue.

after the line
KT8900_fp5 = "M2G314"
Need to add the line
KT8900_ch = "M2G424"

AND
change the line
KT8900_fp5]
to read
KT8900_fp5,
KT8900_ch]

just used my initials ch but probably should have been fp6 insted of ch

This mod made my radio able to read and write as expected.
