# Radio performance
|
||||
|
||||
Please note that the Quansheng uv-k radios are not professional quality transceivers, their
|
||||
performance is strictly limited, somewhat below that of a decent transceiver. The RX front
|
||||
end has no track-tuned band pass filtering at all, and so are wide band/wide open to any
|
||||
and all signals over a wide frequency range.
|
||||
Using the radio in high intensity RF environments will nearly always destroy your reception,
|
||||
the receiver simply doesn't have a great dynamic range, which means distorted AM audio with
|
||||
strong received signals, there is nothing more anyone can do in firmware/software to stop that
|
||||
happening once the RX gain adjustment I do (AM fix) reaches the hardwares limit.

|
||||
Using the radio in high intensity RF environments will most likely make reception anything but
|
||||
easy (AM mode will suffer far more than FM ever will), the receiver simply doesn't have a
|
||||
great dynamic range, which results in distorted AM audio with stronger RX'ed signals.
|
||||
There is nothing more anyone can do in firmware/software to improve that, once the RX gain
|
||||
adjustment I do (AM fix) reaches the hardwares limit, your AM RX audio will be all but
|
||||
non-existant (just like Quansheng's firmware).
|
||||
On the other hand, FM RX audio will/should be fine.
|
||||
|
||||
But, they are nice toys for the price, fun to play with.

# User customization

You can customize the firmware by enabling/disabling various compile options.

You can customize the firmware by enabling/disabling various compile options, this allows

us to remove certain firmware features in order to make room in the flash for others.
