Hello all, and thank you for helping me getting my uBITX V6 up and running again. I replaced C30 this morning and I now have audio. Next will be alignment, BFO, and the frequency display is off. So I'll tackle that soon and if I run into problems I'll start a new thread. Thanks again to all and Evan for sending me some new parts. You guys are the greatest. 73, Richard AG5M

Unknown. I heated the end closer to the back of the PCB, and the cap fell right off the board, with a end still on the PCB. A check of the cap shows it is open, not surprising with the end missing.
Anyway, I found a 0.1uF cap in the junk box, just a tad too big, Hi Hi, to put in on the board, but connecting it to the board gives me LOTS of audio again. When replaced with an appropriate cap I'll be back in business. Then to calibrate the BFO, frequency, etc. And have it on the air again.

Interesting why it cracked/failed... due to mechanical stress, like bent of PCB... temperature shock...? or was it already bad since new...
