The biggest problem with the Wouxun and Boafeng  is receiver overload.  These radios use a direct conversion receiver technique with limited input filtering to give a wide-band receiver.  This works well most of the time but can fail in a strong signal environment.  One national staff CAP member found this out when he brought his, at the time compliant, Wouxun to a NASCAR race.  The receiver was overwhelmed by all of the string VHF transmitters in operation.  That radio was subsequently removed from the CAP compliant list.

If CAP is the main objective for a vehicle mounted, consider a good used EF Johnson 5317 like CAP uses.  They are well built commercial grade radios with 50W output and can be programmed for 2M ham along with standard CAP programming.  They can be found on EBay for about $200.  However, you will need support from you comm officer or wing DC to program for CAP.


Over the past few years, I have owned a number of chinese radios and the two biggest issues I have encountered are 1) most receivers are (very) easily overloaded... some even to the point of non-usability, and 2)  most are very difficult to program, since they use parameters and methodologies not typically seen in other radios.  Proceed with caution before you spend your hard-earned money.
