-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.
-
-----------------------------------------------------------
-
-hfx2.py is a major revision built about complex fir filter
-coeffecients ability and cleaner python script. Inherits
-most features from hfx.py - Powermate knob supported but
-not required, tooltip frequency display, single click
-tuning, AGC, record to disk, play from disk and record audio.
-New feature is 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. The PLL carrier is displayed in the
-bottom display and helps show where on the upper spectrum
-the demodulated signal lies. 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 untill it is locked, and then the PLL carrier
-in the bottom display will jump up and remain relatively 
-constant. There is a slider "AM sync carrier" to play with
-different levels to mix with the signal for demodulation.
-The filter in AM is preset to 2500/12500 (7.5kHz +/- 5kHz)
-and is handy for removing adjacent channel interference.
-Change AM_SYNC_DISPLAY in script for whether to show AM
-Sync carrier or not.
-Run with "-h" for command line help with setting USRP 
-ddc center frequency, decimation, rf data record, playback
-and audio data recording.
-
-There are some controls for controlling a varactor and
-tuning an antenna - just ignore them unless you want
-to build a voltage tuned antenna to track frequency.
-
-There is also code for Web based control of frequency and
-volume - so I can tune the radio with an Ipaq from bed.
-Disabled by default - it takes a web server, some
-directories and scripts to use.

-		HF Explorer Help
-
-	-----------------------------------------------------------------------
-
- 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.

-# 2008-02-07
-# 
-# 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
