[chirp_users] CHIRP VHF / UHF band "low / high" band limits ?

[Tycen Stafford]

I have the QYT - KT8900 (no "D" designation - this one:
https://www.amazon.com/gp/product/B01LYIDJI3) and yes, in CHIRP under Other
Settings those fields are greyed out for me.  However, I was able to put in
our local SAR frequency (155.415).  And, I just turned my radio on and
happened to have some SAR traffic.  So, I can definitely receive on that
frequency.  I don't have any authorization to test a transmit, though.

Have you tried just programming it in and uploading it to the radio?  I
don't recall doing anything special to mine...oh, except for maybe doing a
reset (menu #48) to start off with (be sure to get a backup image first in
case I'm wrong).
