Re: Need Help setting the PA Bias Current for sBITX


 

Aaron, you are doing great! As a former RadioShack tech, I can tell you that getting stable power in the item is always first. Although inconvenient,? this radio troubleshooting will make you an expert on the design and components.? As a teen in late 70s,? I had almost memorized the schematics of the Heathkit hw101 transceiver.? So many modifications and repairs led to that. This radio is completely different,? but keep up the good work and efforts. Document everything and be proud of your achievements.

If anyone notices that I'm making a mistake like this or something then please correct me. I don't have a PHD in electronics and I have not been a ham who has been building this stuff for decades. Don't assume that I know it cause I don't. My goal here is to be able to get back on the air with this so I can start off learning easier to understand electronics and get more complicated as I go. Trying to figure this out, I mean yeah I'm learning some but still it feels like I have jumped in the deep end of the pool with cement shoes on.?
I really appreciate all of the help that people has given me. I really don't know if I'm making more mistakes and making it worse as I go.?
Now i have learned how to measure current (I even made a cable to do this) and how to replace parts, getting lots of experience in replacing parts. I try to look at the schematic and use that to find my way on the PCB but it is still way over my head.??
