I just a took a couple of quick looks.
Nice that they included a memory keyer,
rare in that price range. I didn't see receive & xmit
current draw listed for this unit, which would be nice
to know since this appears to be a "field"
I did notice this in the instructions:
"Included with the unit is a power plug for the FX-2. You will note that the cable has a line marked on the cord indicating “+ Positive”. Make sure this is wired to your Power supply correctly or damage will occur to FX-2!"
Couldn't they add a cheap zener diode for
reverse polarity protection?I realize this is a "Nit" and you could fix it
but all the same,I can't recall a QRP
rig in the last few years without reverse polarity
