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. 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. - - - diff --git a/gr-uhd/apps/hf_explorer/hfx.py b/gr-uhd/apps/hf_explorer/hfx.py deleted file mode 100755 index 1f08bd8ba..000000000 --- a/gr-uhd/apps/hf_explorer/hfx.py +++ /dev/null @@ -1,823 +0,0 @@ -#!/usr/bin/env python -# generated by wxGlade 0.4 on Tue Mar 14 10:16:06 2006 -# -# Copyright 2006,2011 Free Software Foundation, Inc. -# -# This file is part of GNU Radio -# -# GNU Radio is free software; you can redistribute it and/or modify -# it under the terms of the GNU General Public License as published by -# the Free Software Foundation; either version 3, or (at your option) -# any later version. -# -# GNU Radio is distributed in the hope that it will be useful, -# but WITHOUT ANY WARRANTY; without even the implied warranty of -# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

- 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. - Chuck - chuckek@musicriver.homeunix.com - -- cgit
