[PVRCNC] How to capture RSP1 I/Q for more than a half hour at a time

I want to record the 15 meter band (and 20MHz WWV)  during the contest 
this weekend. The 4GB per .wav file limit with SDRuno means 
stopping/starting recording every half hour to create new files. I don't 
want to compromise the quality by decreasing sample rate or using 
decimation. Is there a utility out there that would handle this better 
or shall I just enjoy capturing the files for later study? Using Windows 
or Linux makes no difference to me, but I want to be able to feed .wav 
files to SDRuno for playback this time around.

I managed to get my wrist rocket skills back well enough to put a rope 
up 70' and I'm pulling up a 1/2wl vertical to that height (i.e. center 
around 59'). I think I've worked out a way to keep the feedline out of 
the picture for a true omni pattern using an excellent balun and 
dressing the feedline straight out several feet and then down at an 
angle to minimize coupling. EZNEC predicts about 3-4db at eight degrees 
elevation and I think that will work for receiving. My wife's rehab from 
the first hip replacement is going very well and I look forward to 
putting some RF out later.

Best of luck to all of you in the contest!
