Hi everyone,
I thought I'd posted this message already but it hasn't shown up.. so here goes again.
I'm assembling my uBitx and I'm having an issue when I power it on.? So far I've only wired up the antenna and power.? When I power on the uBitx (using my linear bench PS, set to 13.8v and 1.2a), the uBitx seems to power on just fine, after 103- seconds the power supply starts oscillating (voltage rapidly fluctuates all over the place) and I hear what sounds like a relay clicking. I've 2x, 3x, 4x checked that everything is correct... red/brown twisted together and soldered (as shown in the photo), black to neg side of power connector.? Diode, with strip toward pos side soldered.? To make sure it's not the diode I cut it off (sigh), no change.? To make sure it's not the power connector I unsoldered the wires and just connected red/brown to the PS with an alligator clips.? Again no change.
Is this expected?? Should I move forward with assembly?? What should I do?
Thanks everyone,
