An external freq counter will always do a better test then the one on the unit . Do you have an oscilloscope? A function generator will also have a freq counter . Now the ultimate is a spectrum analyzer. you don't need all these but the function generator will work fine.
Hello, please tell me what you were doing before and at the time of change. Were the digit lights recently switched? Please give me a little more information so I can be more specific in my answer. Thank you.
This problem, really need to be on a bench to test.. FREE at any good cb shop, to tell you what is wrong.... But most times when a freq counter is not working. Either the crystal is bad, poorly soldered, or its not receiving an input signal. Best way to test is to have a second freq counter external inline using coax.. and check the output of the radio and see if it shows correct or wrong. If it is showing correct they you internal freq counter is messed up. and needs to be check for a bad crystal or solder joints. sometimes even the voltage regulators go bad.. If it is showing a wrong freq on external counter then check the radio's crystal and oscillator circuit. this too can be as simple as a cold solder joint. on the solder side check the small surface mount diode near the PLL, next to the PLL shielded covers. It is normally black these come loose often times too. If you need more help feel free to call or text for more help.
check patch lead with multimeter both centers and outers should read but inner and outer togther should not. try a power meter to make sure you are tx ing at least 1/4 of a watt. try freq counter on another rig. all rigs will run on a counter.
That is wrong , I used to have a freq. counter that only read when you applied RF to it on my old Tempo rig and I ran lower 37 and upper 35 so I would key the radio on am and tune the vfo to that frequency and would be on frequency with everone else,I remember hearing that once long ago but it's not true.
