I'll admit the radio purchased from luiton had issues.
Fortunately they were nothing my technician was unable to rectify and the cost was well worth it.
these were more than mere alignment issues ..this was serious problems .
.example burnt boards (like they used a dam blow touch to put a few cans in ..
carriers on ssb (not related to carrier balance )
I.F oscillations causing there to be a squeal on rx on various modes while others were fine ..
IF center so far off it could not be tuned (actual crystals in IF filter were not even soldered in one unit!
.receive dead in one
squeals on tx
random rf power stability issues (rf power dropping or climbing .....
nothing to do with the normal crap from factory's ..
.these were total junk to put it mildly every single fault would of been glaring in QC let alone the rusted lids
others that got gear off them (diff radios) am power would not go over 1w..downward modulation
fm phase modulation when it was supposed to be am mode
squelchs not even working
miss programmed channels where the nz band was actually upside down (1=40 and 40=1) or several ch19 channels programmed as ch24 and 28 (as well as 19)
again stuff that should show up in QC
QC is not fool proof as not all parameters are checked but really that was shocking
granted luiton buy the at6666 off Qixiang (anytone) and should not even lift a lid and i am not saying those are wrong i am saying anything luiton..kingtone..nanafone etc etc i would be highly suspect off as thats what luiton make
