Sorry it has taken me so long to finish this. The frequencies were programmed from this chart. I have not confirmed the Frequency counter. However, I have not adjusted it either. If it is to be trusted, this radio is transmitting a bit off frequency on Channel 20. The Channel 5&12 frequencies may be a rounding error. According to the manual, both the receiver and the transmitter are capable of both narrow and wide band. However, I do not have the means of testing this.
More troublesome is the low power output. The specifications claim 25W at full power. the test showed 17.77W. At low power the specifications claim 5W and the meter showed 4.28W. Ignore the SWR, I am using a Midland MXTA26 and it is ~1:1 on channel 12, but falls off, pretty quickly, on both sides.
