Radio stuck on up search

[skybolt58]

Hi,

I got this ranger rhf-618 given to me, the previous owner shorted pin 5 onthe mic plug trying to trial and error wire up a mic! so with shorting out pin 5 the up button pin, the radio is constantly going up channel the board is the same board ad the 2970n2, the cpu is almost like the 2950dx. but I am trying to find the bad component, anyone have any info on these radios?

Thanks for any info

There are 2 options.
1. Signal from mic socket goes directly to the processor - it is fried.
2. There is a transistor between - transistor is shorted.

CPU

I knew it was in the CPU, but was hoping someone might know what component fried?


Thanks

If there is no transistor between mic socket and processor than CPU is fried. You need to replace it.

Don't throw it out, keep it and use parts from it, or if you feel like it's worth it, send it out to a good tech and they should be able to resolve the issue. JMO. But I wouldn't just throw it away.

Buy a new processor from Ranger USA; or send it to them to fix since you don't have that much invested.
