They also make great for scanners.
BS! They suck as scanners!
Yes they have good sensitivity and selectivity but...
1. You can only scan the channels in the scan list.
2. You can't add or delete channels from the scan list via the keypad. You have to use the programming software.
3. There is no lockout or nuisance delete (see 1 & 2).
4. Scanning stops on any noise or signal, even if the channel is set to PL or DCS decode (or whenever the 'busy" LED is lit). In other words lets say you program a NOAA weather channel with PL decode and start scanning. It will stop on that constant carrier and stay there, even though the squelch won't open and you won't hear any audio. If you need PL/DCS decode to keep out noise or other unwanted signals, You're SOL as far as scanning goes. Also the squelch is flakey and sometimes opens on the slightest noise even when set at 9, the tightest setting.
5. You can't easily skip an active channel. You have to hold an arrow key for several seconds and then wait for the 3 second delay before it resumes scanning.
6. If the backlight is enabled it turns on while scanning, shuts off while scan stops on an active channel, comes back on when scanning resumes. The exact opposite of how it should work.
7. Delay time is 3 seconds and not adjustable. You can also set it to stop or pause 5 seconds and then resume but I haven't tried those modes and don't know if they work as advertized.
8. Scan speed is very slow, about 6 channels per second.
I bought a KG-UV2D last November. It is possible that Wouxun improved the firmware by now and fixed some of those issues but I doubt it.
