Hey Jake
Can you share your flow graph?
I have used the HackRF on SSB up to 5.7 Ghz here on transmit
with the mike plugged into the PC, but can’t figure out how to go from TX to RX easily…
Best DX has been 105 miles here on 3.4 Ghz… but power out on 5.7 is pretty low...
Also has anyone got a simple way to send morse code in real time? I’ve been able to set up
a multiband propagation beacon using the HackRF with a canned CW stream
e mail is ve3dss at hotmail.com
Thanks

Hi all,
How does the "selector block" function in GNU Radio Companion?
In attachment there is the flow (and the properties of the selector) that
I'm doing but I can't understand how the selector block is working.
Thanks a lot
Matteo

Hi Jake,
I?m a newcomer to GRC and I?m trying to learn as much as I can with it. I
installed GNU Radio Companion on Windows 7.
In my flow I?d like to receive a signal, register it into a file, switch
from RX to TX and suddenly transmit it. My problem is that I can?t create a
flow to switch.
In attachment you can find my program.
Thanks for the support
Matteo

All,
Kind of a similar question, but instead of TXing from a file, is there a
way to hook up a microphone to a hackRF and transmit mic output (with a
carrier frequency and appropriate modulation), i.e., for ham radio.

Hi all,
I'm developing my flow with GRC and I need a hand. The flow is almost
finished.
I'm able to acquire a signal and in the same program, I switch in TX mode
by means of a "wx gui chooser" to re-produce the signal. The problem is
that my hackrf doesn't switch in TX mode and so, I can see the signal on
the "fft sink" but my device doesn't transmit. Do I have to use any driver
(soapy)? Which could be the problem?
Take a look at the attachment to better understand the problem.
Thanks
Matteo

Brian,
Attached is a flowgraph which shows how to RX/TX voice. There are several things that need to be explained.
1) My server is in the attic, so I use the network to send/receive the audio to my laptop. The UDP Source and UDP Sink blocks handle that for me, but you could use the GRC Audio Sink/Source blocks.
2) The Select block was written by me to choose which stream to transmit. You will have to use a single stream - probably the Audio Source block, and GUI button to control PTT. Don't try to use
3) The Osmocom Source and Osmocom Sink blocks both use a Device Arguments field of:
soapy=0,driver=hackrf
Using the Soapy driver allows both the source and sink blocks to access the same hackrf device. If there is data available to TX, it switches to Transmit mode; when all the data hase been send, it switches back to Receive. So in my example, the Signal Source and the WAV File source will transmit continuously, while the UDP Source will only transmit when I send voice over UDP from my laptop. But to use the Soapy driver, you have to have Soapy support in Osmocom, which means you probably have to rebuild Osmocom, which means building a bunch of the dependancies; and it's only possible on Linux (as far as I know). It's tough assignment for a beginner - especially if you are used to Windows.
It took several months (off and on) to achieve the above. If I had to start again, and knowing what I know now, I would probably use an SDR for receive, and use the hackrf just for transmit, using two different antennae (or possibly an antenna switch).
Hope that helps.
Jake

Matteo,
if you are using Windows you will never be able to transmit!
as far as I know...only Linux allows GnuRadio and HackRF One to transmit!..
