    Antron 99

    Hi what would you say for a brand new A-99 that is on a 40' pole unfortunately not real far away from a steel roofed and sided outbuilding but the antenna is way above it, the only way I can achieve a great SWR is to have the tuning rings all the way to the top, then the needle hardly even...

    Siltronics LA-550 " keying relay issues"

    You were absolutely correct as it is now fixed that schematic earlier that had the cap and resistor backwards fooled me and I got the base and emitter backwards , I looked and looked

    Nevermind, since they are all soldered together it shouldn't matter anyways I bet

    Siltronics LA-550 " keying relay issues"

    Hi, I don't know if I discovered anything big or not but these components look as if they are installed backwards, schematic show from the base terminal of that transistor a resistor next, then the capacitor but what I actually have is the transistor, a capacitor, then a resistor! Does this...

    Absolutely does sound good and I have Absolutely no problem paying for it ! If anything I owe DX a donation, you guys are great. I will send you my info however I am still going to be working on this thing in the meantime as I really just want to know and find what the problem is with it just...

    Siltronics LA-550 " keying relay issues"

    It seemed to me once i turned the switch to low or high the relay would kick in and just about every wire going into the relay circuit board had power in it I want to check the one coming from the SSB again because it should not have power with the switch in Am position I sure wouldn't think...

    Siltronics LA-550 " keying relay issues"

    I myself am worried more about the PO soldering on the back of it and whatnot, then it apparently blew as I had to repair several traces

    You think they are installed incorrectly or went bad from the shorts we did have and fixed ?

    Siltronics LA-550 " keying relay issues"

    Ya think so ? I replaced both and looked at the schematics tons of times ‍♂️ however if you think this I will focus on them !

    I moved that resistor to where it was supposed to be just to see but no it's still engaging when i turn it off bypass mode

    Siltronics LA-550 " keying relay issues"

    Good deal ! I would have too as there are not many techs around here anymore and I do enjoy working on and learning my own stuff but I always need help from guys like you I could have done even a slight portion of the electronics I have done without assistance from others online because my...

    Siltronics LA-550 " keying relay issues"

    Not only that I am always use to boards that actually have address on them, these boards have nothing so I hold the boards over a light bulb to be able to see where the actual traces even are ‍♂️ and the schematic had me confused as I didnt know this board was broken up into sections as I had my...

    Thank you and you have no idea how much I appreciate it too !

    Siltronics LA-550 " keying relay issues"

    Thank you, I absolutely see everything you stated and you stated it perfectly, the previous owner had obviously turned that resistor down to the output SO-239, was it soldered on, I don't know as when I first removed the board I thought I broke it off the connector, I see the schematic fine now...

    So D9 is this guy right here

    Siltronics LA-550 " keying relay issues"

    I see it I just dont understand why they broke up the schematic of the actual relay circuit board where it is in two different places and trying to view it on a phone is not the easiest as I should have printed it out, the purple wire out goes to the meter and it looks as if the resistor is...

    Siltronics LA-550 " keying relay issues"

    I admit, I am confused you do know I am referring to the one mounted on the keying relay correct?

    Siltronics LA-550 " keying relay issues"

    I am trying to understand this as it looks like it would connect to the coax coming from the plate and load controls where it connects to the relays circuit ? But that other little schematic that has D9 on it has me confused, so this is on the bottom of the amp probably around where I replaced...

    Siltronics LA-550 " keying relay issues"

    Sorry man, I am not the best at schematics and I was focused on the other part of schematic on the relay board, I am pretty much lost now and not sure what to test now
