    Radio stuck on up search

    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...

    there was also a switch off of pin 14 and 9 I removed the extra channel mod! And I bridged the cuts

    OK I tries what you said here already with turning with L13 and 18. as for putting mod back to stock I just unsoldered the wires for pins 10 11 12 14. and jumpered pins 14 where cut and jumped 10 where cut, rechecked solder many times, guess old wasington is too OLD for me..

    OK, ON TP1 I can't get 34.985. closest I get is 34.9306. no change on L18, But L13 makes it change very little, and when I change the channel selector the display changes but the frequency don't, But Now I notice it don't key up no more it use to. red light came on before, But it don't now? I...

    The owner of it, said while he was talking on it , it just lost receive, well I don't think it lost Receive, it is just up on 27.90 something and no one there! just wish I had a scope. make things a little easier

    The lowest voltage I got at TP9 is 3.69 Volts with the selector on ch 1, shouldn't it be 5 volts on ch 40?

    Ranger built cobra 148F GTL

    Where do I test the voltage on what you are asking, this is what I have on the VCO, But I cant do it, because the radio will not go down to ch 1 and I do not have a scope? VCO alignment: Connect DC Volt meter / oscilloscope to TP9 (top leg of R72, just below the VCO card) Set radio to...

    Hi Again, When I got the Washington he said it had no receive, So I hooked it all up with my freq counter Antenna connected at the time, it was reading 27.9856. no matter what channel I put the selector on? so I have the service manual, and did the vco tune up. and set it up on channel 19 on...

    well I am slowly checking components and all seem to be checking out ok? I do have the correct schematic for the EPT014811Z. I am working on 2 radios for the same guy, the other one is a Washington PC 385 board, MB8719. that one is going to be trash I think, no matter what you adjust it...

    Hey loosecannon Is this info you are giving me here based on the EPT014811z board, because that is what I have? Cant find r187 anywhere by vr9 I cant set the bias for the driver, BUT when I turn VR8 the wattage does go up? a little, There is no problem in setting the bias for the...

    Ok then, My transistors all are good, I get the same on the 2166. tests like a diode between C-E, I was getting the info from that video you posted, he stated that C-E should not have any current either way. Now I still have to find out why I cant adjust the Bias on the driver and I...

    Yes I know the Base -Collector conduct one way and the base - emitter only conduct one way, BUT what about the emitter and collector, I under stand for a good transistor, they should not conduct either way? right?

    Ranger built cobra 148F GTL

    So what you are saying, that the Video you posted where it says that there should be no reading between the collector and emitter , that it don't matter if there is a reading? one way

    Ranger built cobra 148F GTL

    Yeah I saw that, Wow I guess every 1969 and 2166 I have even 2 new ones are bad, since I get a reading one way between emitter and collector!

    Ranger built cobra 148F GTL

    Gee am I testing these transistors right? Here is how I do it, I set the DMM on Diode test, I probe the collector and base both ways and it tests like a diode, then I test the base and emitter both ways and it also tests like a diode? then I test the collector and emitter both ways...

    Well I just took the final out 2sc1969 and tested it with a DMM on diode test, between the base and collector and emitter tested one way had current and the other way didn't, that is good, but between the collector and emitter there should not be current either way and there is, so the final is...
