[Scan-DC] Dongle hacking blues

[Alex Fraser]

Found some SDR dongles in the pile.  I decided I'd had enough of that 
weird European TV jack.  I dug around a bit as I know I had a box of SMA 
stuff from when I was building drones.  Sure enough I found the box and 
there was 2 nice gold plated circuit board mount jacks, so I unsoldered 
the crap bit and figured out how to get the SMA in it's place. Not real 
pretty but functional or so I thought!  I had forgotten all about SMA 
polarity differences.  I'm not sure if I soldered on a reverse 
connector  or regular one, but it sure was the wrong polarity.  So I go 
back in the box in the pile to see if I had another jack and hooray, I'd 
forgotten that I went through this years ago and had bought some 
polarity adapters.  It's nice when things work out!
