Hi folks,
I've messed up this ubitx a lot. Learning as I go... I guess. Today I pulled it out again to give it another shot, and found the burnt trace that caused me to put it away 2 months ago. That wasn't even the original issue with it, so I knew I had to find the other one. I have 12 volts on the tabs of the irf510s, but none on the gates while TXing. IIRC there should be around 4 volts there. Somehow while testing voltages between ground and the IRFs I burned another trace (between PA PWR and L8). Luckily this one was far easier to fix.?
Prior to burning the traces, I came here trying to solve the issue. Here's the link to that thread if it helps at all:?/g/BITX20/topic/24923512?p=,,,20,0,0,0::relevance,,No+RF+out+SSB,20,2,0,24923512,ct=1&ct=1
No idea what the problem is, I've been at this for over 6 months now, on and off of course. Any help figuring this out is much appreciated. Thanks!
