OK, guys! I guess I've been living under a rock for too long.
This morning I just stumbled onto this listing from eBay for an
inexpensive, tiny - and I mean SMALL power supply module from China with
digital r/o, 2 amps (perfect for QRP), and fully adjustable. I feel kinda
small myself right now, I didn't even know this sort of QRP friendly stuff
was even out there. The winning bids for these modules seem to be under $20
w/ FREE shipping from Hong Kong. Without the digital r/o, some modules of
this sort are selling in the TWO dollar range.
Have you used one of
these modules? What are your experiences - any good? I just can't believe
the price/ performance ratio - let alone the size of these
