[Hackrf-dev] HackRF hardware problems

[ccrypti at nym.hush.com]

I shipped mine back, was DOA, at least got a refund but probably 
won't get my customs fee back and paid for the return shipping. I 
tried to contact Michael before i shipped it back but got only 
<crickets> back.
Kind of disappointed with this, so i'm most likely going to save a 
budget for the USRP B200 or B210. But this time i'll check reviews 
and any issues first before throwing again money.

Anyway, thanks to the good people on this list who provided advise 
/ troubleshooting tips, appreciated !
