As seen by these answers so far, there are lots of options. If, like me, you'd prefer to go the kit or pre-built route, there are options from cheap and simple to expensive and more complex. I persona

I'm new with the uBITX, too, so I'm no expert. Just some initial thoughts. Regarding WSPR, what you describe doesn't necessarily sound unusual to me. I've got a WSPRLite from SotaBeams and I've had si

@Curt: Yeah, two fuses is probably overkill in my case. I don't anticipate running the PA at a higher voltage, but you never know. I've already cut the holes in my case for two fuse holders, though, a

@Mark: Ok. Thanks. I kind of suspected it was a typo. Five amps sounded a bit out of place for the +12V line given that 2-3 amps is recommended for the PA PWR line. Now, about that diode... :-)

@Curt: I'm fine with the 2 amp fuse on the PA PWR line. My question is about the "5 amp" fuse on the +12V line as shown in the wiring diagram I described. As I said before, I was just curious about wh

@_Dave_ K0MBT: I've got a 2 amp fuse on the PA PWR line and a 0.5 amp fuse on the +12V input line, as I've seen recommended elsewhere. But the wiring diagram reads "5 amp" on the +12V line. I was just

I just wanted to verify the recommended fuse value for the +12V line on the uBITX. The latest wiring diagram, "Wiring Diagram Ubitx V5 V2.0.pdf", shows the fuse as "5 amp Fast Blow" (see lower left of

I recently wired up my uBITX. I've attached a photo that shows how I wired up the DC socket with some fuses. I used two fuses: one 0.5 A fuse for the main board (red wire) and one 2.0 A fuse for the P
