I have a balun, and the balun has terminations for two wires and an SMA on
the other end. I know you have probably seen it. It's the one that is
made by Nooelec I think and people usually purchase this 9:1 balun with the
ham it up converter. However, I was going to use this balun with a 30ft
SMA cord and discone. I have the connections to connect my SDR or HackRF to
the 30 foot cord, into the balun, out to two wires, then into a two wire to
BNC terminal, then the BNC will go to a UHF PL 279 which is how the discone
antenna is terminated. Am I using this balun correctly? If not, is there
a good all encompassing reference manual that will teach me all of this
stuff? My wireless communications book touches on Baluns and ununs but
doesn't mention how Baluns should be used. Also, is there a way to measure
impedance of the antenna and the transmission line? Would a network
analyzer be used for this? I have a USB analog discovery scope which also
has a network Analyzer incorporated in to its multi functions. I have a
desktop function generator and desktop oscilloscope also. Just FYI if you
have any suggestions you know what kind of equipment I'm working with. I
have a whole lab setup at home with just about every type of measuring
equipment and electronic components. I can make just about anything.
Maybe I shouldn't even use the balun with my discone and make a half wave
dipole antenna? I didn't think the balun has to do with the frequency that
your trying to receive, but makes sure the impedance is matched correctly
so the antenna is more efficient.
I was going to start reading SDR for the hobbyist soon. Hopefully that's a
good reference for all this stuff.
I have a million more questions, maybe I should just go read a damn book,
right? Lol. Or try it and see what kind of results I get.

Here is how I fixed my Ubuntu (15.04) Pip issue, this may help you also.

The commands were from memory so you may not need to use each one.

Why run pybombs as root it will ask for sudo when it needs access, other
than that it will install everything in your home area I think the
default used to be target.

some similar complaints from other people, is this bug resolved or not?
should I revert back toan earlier versin of pybombs? thanks.

Re: [Hackrf-dev]
cannot talk to more than one hackrf one withUbuntu 14.04 See if you can
upgrade gr-osmosdr: apt-get install gr-osmosdr When you start grc, it
should print out the serial numbers of all the HackRF devices it finds - and
indicate if it's a match or it's skipping it based on the serial number you
provided. Note, I'm assuming you upgraded libhackrf when you upgraded the
firmware and the cpld. -- Cinaed On 03/28/2016 06:12 AM, Trek Liu wrote:

I am
running ubuntu 14.04, with three HackRF one devices connected to the system.
All three were with the 2015.07.2 firmware and the CPLD programs were also
updated individually. HackRF_info can identify all three devices (see
below), however when I run osmocom_fft with -a hackrf=0/1/2 options, the
same HackRF device is always selected for streaming instead of the specified
ones by -a hackrf=options (I can see
the RX led lit from the same device every time). Same thing is observed with
Gnuradio-companion. could anyone give a clue? Accroding to
the gr-osmosdr wiki page, one can use the serial number instead of the
device index: http://sdr.osmocom.org/trac/wiki/GrOsmoSDR#HackRFSourceSink
Maybe that works better. Alex
