ham2mon's Issues

Print help when starting without arguments

Isn´t the intended behavior to print the possible arguments / help when starting ham2mon.py without arguments?

I get this:

linux; GNU C++ version 5.3.1 20160413; Boost_105800; UHD_003.009.004-release

RuntimeError: gr::io_signature(3)

I use a HackRF and after figuring out what arguments I should use everything works fine. I use GNU Radio version 3.7.9 and Python is 2.7.11+.

I might come up with some code changes to fix this it is is the intended behavior and the issue can be confirmed from more users.

Ham2mon and Python 3

Gnuradio 3.8 now uses Python 3. Also, gr-osmosdr won't build with Python 3. Ham2mon does not currently support Pyhon 3.

I am not in touch with the timeline for gr-osmosdr to python3. I don't see anything that indicates this is in the works even. Anyone here know what plan is on this? I see references to Soapy which seems to have same intent as gr-osmosdr. I can ask this question elsewhere but starting here to get the input of ham2mon users.

Won't run on Raspberry Pi 3

When I invoke the application I see flashes of errors that clear away quickly before they can be read and I see text staircasing. In an attempt to calm the output I piped the output into strings so the VT terminal commands won't work. Below is a snippet of the errors I could catch.

Garbled Audio (Wav File)

Sound from the speakers is good but what is written to disk with -w plays back garbled. This happens on two different computers. Output of aplay:

Playing WAVE '465.020_1464177108.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono

I was going to dig deeper into the code but maybe someone has run across this.

Thanks,

Any ideas?

Any need to limit length of audio files?

For my application I have added an option to limit the length of a demodulation to N seconds. I need this because I mostly run ham2mon headless and use a Web based interface to listen to audio files created by ham2mon. In this case I do not want open ended audio files or even very long ones.

Let me know if this feature would be of benefit to others and I can submit a pull request. It may only be me that has a use for it.

RuntimeError: gr::io_signature(3)

Hey, I didn't find any answers for this, so I thought I'd ask. I'm on openSUSE 42.1. gnuradio is version 3.7.8-3.11. I have a generic RTL2832U. gqrx works, so I know the RTL is accessible via gnuradio.

Running this:
./ham2mon.py -a "rtl" -n 4 -f 145E6 -r 2E6 -g 20 -s -40 -v 0 -t 30 -w

And I get this:

Any Idea whats wrong?

Information Request: Spurious Transmissions

I mostly listen to NBFM with ham2mon. For things like transmission in my local area it works great. However, I also use it at automobile races that have heavy radio traffic with varying degrees of signal strength.

What I see in this case is there are times where not only is the expected signal received but "duplicates" across other frequencies. These duplicates tend to lower quality and can be mixed with signals on those other frequencies.

This may be a question of adjusting the gain based on my location. However, I am using ham2mon in a mobile way (on a golf cart over 640 acres of area).

Currently I am using an RTL based receiver and played around with hardware AGC. This didn't appear to help.

Are there any options to address this? It seems like this is a fundamental issue so I must be missing something basic.

Thanks,

Jon

Airspy Mini on SBC (Pi compatible) / ham2mon performance tweaks?

I can use airspy_rx to stream data from Airspy 3MSPS (lowest supported rate). Also streams fine at 6MSPS. With ham2mon gnuradio indicates there are overruns. There is lag in UI and audio files sound like they are sped up. Can anything be done with the gnuradio flowgraph in ham2mon help improve performance? Yes, this is pretty vague so if more info is needed let me know.

Information Request: Setting Auto Gain With RTL Driver

This is probably not a ham2mon question but here it goes...

I want start ham2mon and pass argument to rtl driver to have it use AGC. I have tried things like this and it is not clear to me that it is set: -a "rtl=0,gain_mode=Automatic"

I haven't dug too deep into to code but expect ham2mon just passes this like other settings that I know work.

Any input would be appreciated!

Thanks,

John

Information Request: Gain Names and Airspy

I am working with an Airspy Mini and getting an understanding of gain controls that are available. From my review of gnuradio source it looks like the gain controls a particular brand of SDR has varies. From what i have seen ham2mon doesn't currently take this into account. So in case of Airspy the BB gain control in ham2mon doesn't do anything which makes sense as it has a Mix gain setting instead. The other 2 gain controls seem to do right thing (not 100% sure yet).

Here is a point in gnuradio where difference is:
https://github.com/osmocom/gr-osmosdr/blob/4d83c6067f059b0c5015c3f59f8117bbd361e877/lib/airspy/airspy_source_c.cc#L446
https://github.com/osmocom/gr-osmosdr/blob/4d83c6067f059b0c5015c3f59f8117bbd361e877/lib/hackrf/hackrf_source_c.cc#L563

If the above seems off let me know.

Question: To support Airspy do we add another gain (Mix) to ham2mon? Should the design be changed to support something more dynamic?

Audio playback choppy and incorrect speed

RTL-SDR on R-Pi3. No issues running, but per title the playback files are choppy. After some troubleshooting, seems something in the GR chain is off when sample rate is something other than 1Mhz. Playback is normal at this sample rate.

Choppy audio: ./ham2mon.py -a "rtl" -n3 -f 1465E5 -r 2000000 -g 20 -s -40 -v 20 -t 20 -w
Normal audio: ./ham2mon.py -a "rtl" -n3 -f 1465E5 -r 1000000 -g 20 -s -40 -v 20 -t 20 -w

I'm looking into it now, but didn't know if I was missing something obvious.

Airspy Mini setting sample rate

I am attempting to use an Airspy Mini with sample rate of 3 MS/s (it supports that and 6 MS/s). I am starting ham2mon like this:

ham2mon.py -a "airspy" -r 3E6 -w -m -b 16

However, the gui shows 10 MS/s and not 3. I haven't gotten into the code yet and want to make sure I am not missing something basic.

Did install http://sdr.osmocom.org/trac/wiki/GrOsmoSDR for so far.

Installed gnuradio and dev files under ubuntu willy.

Maybe it has to do with:

used: sudo cmake ../ -DENABLE_OSMOSDR=ON -DENABLE_PYTHON=ON
this gave some erros.

What libs and or packages do i exactly need on my system ?
