  1. Don't bother. Worst POS I ever had the displeasure of trying. Of course I'll have to get Paypal involved to get anything out of the seller. Receive sensitivity is so bad that the radio is unusable. Won't decode PL so I'm stuck with CSQ receive only. The quad watch is a joke. Every time it checks another channel you get a squelch tail. Same with scanning... squelch break every time it checks the next channel. I didn't even try to transmit. In all my years of radio since 1970 I have NEVER seen anything this junky.

    1. I had the same problems. Adjusted squelch level, no help.
      True POS
