For information, I have two UBC125XLT's, - first one purchased 2017, the
second about 8 months ago. One thing that I was surprised at & impressed
with in the first scanner, was the lack of birdies, especially in searching
the Mil Air Band.
Lock out was only required a few times, to complete a full search of 225-400 Mhz,
and generally the scanner seemed to have fewer birdies than expected.
The second scanner has many more birdies, & in searching Mil Air band on this
one, lock out is required in the tens of times (i have a list similar to the
scanner in question, but i was comparing with a known radio using different
antennas, rather than no antenna)
(A quick check, i found some birdies i have noted, match the list given for the
scanner in question)
I assumed it was down to hardware changes, but also noted the firmware versions
were different (not surprising due to the age difference).
The second scanner hasn't been used much yet, but sensitivity comparison &
other performance so far, seems equal.
Because the first had so few birdies, i'd even thought perhaps they were being
'dealt with' in the firmware & this wasn't the case in the second, or it was just
down to hardware changes ?
The birdies in the second scanner could possibly be considered normal, but why
such a big difference & why so few in the first radio ?
Up to now, i hadn't found any more info & didn't consider the second scanner as
faulty, but more like the AOR radios i own, as far as having to lock out more
frequencies when searching.
When scanning directly entered frequencies, it isn't as much of a problem, unless
a birdie clashes with an interesting frequency !
