    Siltronics LA-550 " keying relay issues"

    I guess now that I am home and see the schematic it is a capacitor, so I will probably be testing that one So, it's a 2 watt 10,000 ohm resistor, and it does look like it goes to the center of the output coax

    Siltronics LA-550 " keying relay issues"

    It broke off the antenna connector when I was originally removing the board and it had looked like it was soldered to the center stud by the way the solder looked right there when it came off but whoever worked on it before I am wondering if they soldered that to the wrong spot but I ended up...

    That one down at the bottom left, where is it actually supposed to go ?

    Siltronics LA-550 " keying relay issues"

    I used the 2NC945 I had to twist one around pretty good but it worked out ok but no I have not checked them since the install, but sitting here on break I am thinking about something that I may have done incorrectly, there is a large resistor on that relay board on the bottom and it goes down to...

    Siltronics LA-550 " keying relay issues"

    What does that pot really do anyways? Is it possible that is the issue with the relay staying engaged when switched to low or high power without keying the mic ? Thanks

    Siltronics LA-550 " keying relay issues"

    And thanks for the advice I ended up staying up last night until blurry eyed with this thing past 1 am back to work at 5 , well, you were correct again I had Q1 transistor incorrect! After I put them the way they are supposed to be I bet I checked the schematic 20 times, unfortunately the...

    Siltronics LA-550 " keying relay issues"

    Ok, I sure will ! I have to eat and get ready for bed but i will check the orientation of them tomorrow after work from the schematic, I sure appreciate you helping me with this mess

    Siltronics LA-550 " keying relay issues"

    Or 1.275 k ohms one direction no continuity either, the bad one I replaced in this board does have continuity

    Siltronics LA-550 " keying relay issues"

    It tested like this one direction only and still installed in the board

    Siltronics LA-550 " keying relay issues"

    They usually need to be removed don't they ?

    Siltronics LA-550 " keying relay issues"

    Can I check it in the circuit or remove it then check it ?

    Siltronics LA-550 " keying relay issues"

    Maybe I ought to stick to looking at the actual schematic and not assuming, sorry

    Siltronics LA-550 " keying relay issues"

    Ok, yeah I am not very good at identifying them it just looked like one that I saw online or this one I have here, i thought it looked like it

    Siltronics LA-550 " keying relay issues"

    Isn't there a zener diode right there between the cap and large resistor ?

    Siltronics LA-550 " keying relay issues"

    I replace the D5 on the keying relay board, now the relay kicks in but it kicks in right away when I switch to low or high power without keying the mic ??? ‍♂️

    Siltronics LA-550 " keying relay issues"

    I now also have 17 dc volts at the green and blue and white wire at the relay with the low or high power on and the power goes away when switched to bypass like it is supposed to ! However the relay still is not kicking in but I may need to test that zener diode and other stuff on the relay...

    Siltronics LA-550 " keying relay issues"

    19.3 volts DC I meant

    Siltronics LA-550 " keying relay issues"

    I went ahead and used a 1N4004 and installed it now I have 19.3 volts at the cathode and no more buzzing from the power supply!

    Siltronics LA-550 " keying relay issues"

    All I have of diodes variety pack I have here are 1N4004 or 1N4007 would either of those be ok to use ?
