Homebrew
I've had a large collection of BF998 dual gate MOSFETs sitting around in the junkbox for quite a while now (acquired from KE6F), but I've never really known what to do with them. I feel like I own a fairly decent library of QRP/homebrewing literature, but there seems to be very little detailed information on [...]

Wayne McFee, NB6M has created a custom PCB for his variation of the MARC LC Meter, along with providing a kit of parts. I just received my kit yesterday and was very eager to build the thing, since it's one vital piece of test gear that I don't yet have. Stuffing the PCB according to [...]

I've got a half dozen unbuilt kits, an oscillator, single ended mixer, and an audio amp all destined to be a DC receiver (hopefully). An 80M [...]
