-hfx.py is meant to be a full-featured Long Wave / Medium Wave
-and Short Wave (250kHz to 30Mhz) AM and Single Sideband receiver.
-It uses the USRP with a Basic RX board, and will need an
-antenna and some preamps, about 30db gain will work. See the
-'Help' menu or hfx_help for more info.
-
-----------------------------------------------------------
-
-Powermate knob supported but not required, tooltip frequency display,
-single click tuning, AGC, record to disk, play from disk and record
-audio. Ability to tailor the audio passband with two sliders over the
-spectrum display. The sliders almost align with the actual
-frequency. Preset filter settings for LSB (-3000 to 0kHz), USB (0 to
-+3000kHz), CW (-400 to -800Hz) and AM (-5kHz from carrier to +5kHz).
-
-AM now switches in a synchronous PLL detector with the carriers at
-7.5kHz. Everything gets shifted up 7.5kHz in AM, center frequency,
-tooltips, etc. The target AM carrier needs to be closely tuned in, it
-will have a hollow sound until it is locked. The filter in AM is
-preset to 2500/12500 (7.5kHz +/- 5kHz) and is handy for removing
-adjacent channel interference.
-
-There is code for Web based control of frequency and volume - so
-I can tune the radio with a handheld device. Disabled by default - it
-takes a web server, some directories and scripts to use.

- -----------------------------------------------------------------------
-
- Command Line Switches:
-
- -c DDC center frequency, set band.
- -c 7.2e6 or -c 7.2M for 40 meter ham band.
- Default is 3.9e6 80 meter ham band.
- Example:
-
- hfx.py -c 9500k
-
- starts up in the 31 meter band.
-
- -a Audio output file. Output file for 32kHz two channel
- signed word audio. Two channels are used for
- independent sideband. This file can be converted
- to a wav file with sox. Example:
-
- sox -c 2 -r 3200 file.sw file.wav
-
- sox needs the .sw extension to indicate file type.
- If not specified no audio file is created.
-
- -r Radio output file. File to write RF data to for later
- demodulation. Records the entire band to disk, width
- determined by sample rate/decimation. Be sure to
- note the decimation and center freq for later use!
- Example:
-
- hfx.py -c 900e3 -d 80 -r rf_data_AM-c900e3-d80
-
- writes a pre-demod rf file centered on 900kHz with a
- bandwidth of 800kHz (That's 80 AM stations!). The
- center and decimation could be put in the filename for
- proper use later.
- If not specified no rf data file is created.
- At default 250 decimation disk usage is about
- 8Gb / hour.
-
- -i Radio input file. Use to play back a previously
- recorded rf data file. Example:
-
- hfx.py -c 900e3 -d 80 -i rf_data_AM-c900e3-d80
-
- plays back the previously recorded band, no
- usrp hardware needed. Tune about the 800kHz wide band.
- When playing a recorded file, time controls
- fast-forward and rewind are available.
-
- -d Decimation. Sets sample rate and bandwidth.
- This is the factor that the usrp sample rate, 64e6,
- is divided by. Default is 250 for 256kHz bandwidth
- which is enough to record a ham band without
- eating up disk space too fast. The 64e6 sample
- rate limits the upper practical frequency to 32MHz.
- The Basic RX transformer limits the lower frequency
- to about 200kHz.
-
-
- Powermate Knob:
-
- A Powermate knob is recommended but not necessary. If a knob
- is used, it is in one of 3 or 4 modes controlling frequency,
- volume, filter and (if playing a recorded file) time.
- Pushing the knob switches mode and the buttons on the HFX panel
- change to show which mode is in effect. Then just turn the knob
- to set frequency, volume, filter or go fast forward or rewind.
-
-
- Bandswitch:
-
- Across the top are a set of predefined bands and buttons
- to rapidly switch to the center of that band. To change a band,
- type the frequency in Hz into the box under "Center Frequency",
- then press "Set" on the left, then the button you want to
- program. From then on (untill the program is exited) pushing
- that button takes you to that band. To make a band button
- permenant edit the hfx.py script with whatever frequency you
- want assigned to what button.
-
-
- Frequency:
-
- There are 6 ways to set the frequency.
- 1) Move the slider with the mouse
- 2) Use the Spin Control up/down arrows (very fine 1Hz control)
- 3) Type the frequency in Hz into the Spin Control
- 4) Turn the Powermate knob
- 5) Web control.
- 6) Clicking on the FFT display to set demod center. This is very
- convenient for tuning +-15kHz when you see a signal on the
- display. If in Lower Sideband, clicking just to the right of
- a signal will tune to it immediately. Clicking several times
- on the far right right or left of the display will rapidly
- tune up or down the band.
-
-
- Volume:
-
- Move the volume slider with the mouse, or push the Powermate knob
- untill the volume button is active, or click on the volume button,
- then turn the knob. Volume can also be set by web control if web
- control is setup and enabled.
-
-
- Filter:
-
- Similar to volume, switches in any of 30 audio filters from 600
- to 3600Hz in Sideband or up to 5kHz in AM.
-
-
- Mode:
-
- Demodulation modes are chosen by clicking on the buttons for
- Lower Sideband, Upper Sideband, or AM.
-
-
- PGA:
-
- PGA slider sets the rf gain in the Analog-to-Digital converter
- before digitizing. 0 to 20db gain easily shows up on the FFT
- display.
-
-
- Time:
-
- When playing back a recorded RF data file, you can enjoy the
- freedom of rewinding or fast-forwarding. Replay a weak signal
- or skip through annoying AM commercials.
-
-
- Antennas and Preamps:
-
- The USRP Basic RX board is not sensitive enough for anything but
- the strongest signals. In my experience about 40 db of small
- signal gain is required to make the HFX as sensitive as other
- receivers. Some working amplifiers are the Ramsey PR-2 with 20db
- gain, fairly low noise and more bandwidth than we can use here.
- Also the amp modules from Advanced Receiver Research are nice.
- I use an ARR 7-7.4MHz GaAsFET 29db amp with .5db noise at the
- apex of a 40 meter dipole with excellent results. Another
- amp I like is a Minicircuits ZHL-32A 29db amp but they are
- expensive and hard to find. Also it may help to use some filters
- to keep strong local signals from the ADC, or limit rf input
- to the band of interest, etc.
- Resonant outdoor antennas, like a dipole, in a low-noise (away
- from consumer electronics) environment are nice. Long random wires
- with a tuner work. I like a small indoor tuned loop made from 10ft
- of 1/4" copper tube, a 365pf tuning cap and a pickup loop connected
- to rg-58.
-
-
- Web Control:
-
- To control your radio remotely, ensure you have a web server
- (Apache, etc) working and a compatible directory structure in
- place. Directories /var/www/cgi-bin/commands and
- /var/www/cgi-bin/state must already exist. You will need a
- home page with forms and a set of scripts to put commands in
- and put the current state on the home page. email me for further
- help. Setting WEB_CONTROL to True in hfx.py turns on the timers
- that check for commands and update the state.
-
-
- IF Output:
-
- There is a provision for outputting un-demodulated complex
- through the audio out in stereo for use with Digital Radio
- Mondial (DRM) or using a seperate demodulation program like
- SDRadio (by I2PHD).
- Set IF_OUTPUT to True in weaver_isb_am1_usrp4.py.
-
-
- --Good luck and happy LW/MW/SW Exploring.

-# These files have not yet been update to use the new top_block/hier_block2
-# interfaces. Until someone does that, this files will no longer run.
-#
-
-
-The files in this directory implement a fairly simple HF radio that works
-with the basic rx daughter board on the USRP.
-
-Many thanks to the Gnu Radio folks for a great new way to waste large blocks
-of time in infinitely tweaking a huge number of free parameters.
-
-Start the receiver by running the radio.py in this directory. Or from the
-Python prompt type "from radio import *" and you'll get the prompt back
-with the receiver running. You can then poke around to see what's going on.
-
-There are two spectrum displays. One is the output of the USRP and displays
-about 300KHz of bandwidth centered at the current tuning freq. The other
-displays the output spectrum of the demodulator.
-
-The demodulator does AM demod using the complex modulus block from gr. It
-does SSB demod using the frequency translating fir filter as a complex
-hilbert transformer. The taps for this filter were generated using a program
-called Scilab and the Scilab program in the file hfir.sci. More details in
-the associated files.
-
-Tune the receiver using the spin buttons under the big frequency display.
-
-The agc block is a roll your own. The standard agc in the newer CVS updates
-seems to work but doesn't seem to have adjustable time constants or provide
-access to internal signal nodes which are used for the RSSI.
-
-The AGC authority (a sort of gain parameter) and the reference level used
-in the power to dB computagion can be adjusted using the spin buttons.
-
-The audio bandwidth can be similarly adjusted from about 50Hz to 10KHz.
-
-The GUI layout was produced using wxGlade. The file radio.xml is the GUI
-specification. It will produce a file called ui.py which is subclassed
-by classes defined in radio.py. The ui.py is purely generated by wxGlade
-all app specific code for the GUI is in radio.py.
-
-Most of the actual signal processing code is built up in the other included
-files using the hierarchical block facilities. This organization should
-make it easier to tweak to your heart's content.
-
-Known bugs weakness and other
-
-wxPython and wxGlade seem to conspire to insure that the layout can never
-be exactly what you have in mind.
-
-Some of the controls don't behave as one might like. wx spin controls
-and spin boxes only support integers so it is rather a nuisance to make
-units come out nice. In the process of development I came up with a reasonable
-kluge so there is a mixture of approaches.
-
-Enjoy.

-// designs a complex tap fir filter akin to the hilbert transformer.
-//
-// The hilbert transformer is classified as a linear phase fir
-// with allpass magnitude response and 90 degree phase response for
-// positive frequencies and -90 degrees phase for negative frequencies.
-// Or, if you prefer, normalized frequencies between .5 and 1 since
-// negative frequencies don't really have much meaning outside the complex
-// domain.
-//
-// Normally one would use the hilbert transformer in one leg of a complex
-// processing block and a compensating delay in the other.
-//
-// This one differs in the following respects:
-// It is low pass with a cutoff of .078125
-// The filter is a lowpass kaiser windowed filter with parameter 3
-// The phase response is 45 degrees for positive frequencies and -45
-// for negative frequencies.
-// The coefficent set is used in one path and the same coefficients
-// are used time reversed in the other. This results in the net effect
-// of +/- 90 degrees as in the usual hilbert application.
-//
-// The coefficient set can be used in the gnuradio frequency translating
-// fir filter for ssb demodulation.
-//
-// This isn't as computationally efficient as using the hilbert transformer
-// and compensating delay but fascinating none the less.
-//
-// This program is for the scilab language a very powerful free math
-// package similar to Matlab with infinitely better price/performace.
-//
-// compute the prototype lowpass fir
-// length is 255 (odd) for the same symmetry reasons as the hilbert transformer

-"""
-Here is a bit of code that will receive SCA analog subcarriers of FM
-Broadcast Stations using the USRP. It is a modified version of
-usrp_wfm_rcv.py.
-
-Common SCA frequencies are 67 kHz and 92 kHz. SCA is used for Reading
-Services for the Blind, Background Music, Foreign Language Services, and
-other services. Remember you may hear static when tuned to a FM station
-because this code only outputs SCA audio.
-
-The USRP gain is critical for good decoding. Adjust for minimum noise.
- I use the Post FM Demod FFT to check for SCA subcarriers and to adjust
-the USRP gain for the lowest noise floor. The stereo pilot at 19 KHz,
-the stereo difference signal around 38 KHz, and RDS at 57 KHz are also
-displayed on the Post FM Demod FFT if present.
-
-The range below 67 kHz is used for SCA only when Stereo is not used.
-
-The SCA recieve range is not as far as the main FM carrier receive range
-so tune in strong local stations first.
-
-I tried to comment the code with the various parameters. There seems to
-be several choices for a couple of them. I coded the common ones I see
-here.
-
-In the local area there are a couple of stations using digital SCA.
-These look similar to narrow DRM signals and I wonder if they are using
-OFDM.
