I saw him selling an N210 one week, then the next he was trying to sell an N210
+ some Micro ATX machine for 2400$;
what a nice holiday surprise
anyone else buy a n210 from seller "occupyonline" ?
They sent a envelope with a CDROM of ubuntu and some paperwork on how to
install!!
I know it was a gamble as he had "0" feedback. It looked legit, and to get one
for 1200$, with ebay buyer protection, I am not worr
ok thaks. I wasnt sure if i should add attunetion or simply decrease tx power.
Now that im thinking about it, maybe its not really neccessary to sweep the
feeq range? The usrp could just shoot a 8mhz wide signal (noise?) into the
thing, and visualize in realtime the notches and pass bands change
If i were to use a usrp to tune a repeater duplexer, could i just connect both
WBX ports directly to the can's, and use one port to tx and the other to RX?
Would i need to add some inline attenuation? For clarification i would be doing
this with 1 WBX

back when i had a usrp i setup an adjustable dual channel fm tuner with freq
translating filters in grc. its setup for usrp1 so i could not capture the

you could use a VCR right? channel 3? or cable TV provideri made a bunch of
capture files with my USRP as they shut down the analog signals. shortly after
my raid5 array crashed and i never made backups
i did try another one, its uploaded herehttp://kd8eyf.org/capture_files/i never
tested it so
One way is to use a throttled file source sink, and use someones capture
file.
I have some here you can download online.
