"12-isb-kske-wav.zip" contains "12-isb-kske.wav", a 40-second clip of 12 kHz Independent Sideband (ISB) useful for testing any SSB or ISB hardware (or software) that employs a 12 kHz last IF. A local AM broadcast station (KSKE) was used to provide audio for this test clip (the test clip was recorded with Windows Sound Recorder at 32 kHz, 8-bit PCM, Mono from JI3GAB`s Generator software). After unzipping the file, Windows Sound Recorder or Media Player can be used for playback.

"12-isb-tv&aud2-wav.zip" contains "12-isb-tv&aud2.wav", another 40-second clip of 12 kHz Independent Sideband (ISB) useful for testing any SSB or ISB hardware (or software) that employs a 12 kHz last IF. The lower sideband is color video (WNDSURF1.AVI from the Microsoft website) at 1 FPS, with an ID "crawl" at the bottom of the screen (the video was generated using ZL2AFP`s "FFT-TV" software -- the software also includes a recording application that allows playback at 10 FPS). This software can be downloaded from the "FFT-TV.zip" link listed below. The upper sideband is voice ID`ing the transmission. The ISB signal was generated using JI3GAB`s Java DSP-SSB software (see JI3GAB`s website). After unzipping, the .wav file can be played back using the Windows Media Player application, most useful with the infinite loop (repeat) option. A VLF converter (i.e. Palomar Engineers) can be used with an HF transceiver to receive the ISB signals directly from the soundcard output.

"Advanced (SSU) Description 2.txt" is a text file describing the Soundcard Switching Unit (SSU), used to interface the PSK-10-SDR Transceiver to your PC`s soundcard(s). With the SSU, you can operate SSB, data modes (such as PSK-31), image modes (such as SSTV or NBTV) or Independent Sideband (ISB), where image modes are operated simultaneously with voice. Construction details and a test procedure are included in this document. The schematic and block diagrams, together with a wiring diagram, are found in the "Advanced (SSU) Figures.zip" file listed below. The SSU is not suitable for use with JI3GAB`s Digital SSB Processor (DSSBP) software.

"CaronGAM.zip" is a collection of .GAM files compiled from examples in Wilfred Caron`s book Antenna Impedance Matching, and an article in the ARRL Antenna Compendium, Vol. 4. The student of antenna matching will find it instructive to work through the examples in Caron`s book and article. Using QuickSmith software instead of the manual Smith Chart technique in the book, learning the principles of antenna matching is made much less tedious. The .GAM files are ready for use with QuickSmith. A README.txt file is included, explaining the use of the .GAM files.

CO49+AFC.zip
Filesize:

http://www.hamsdr.com/personaldirectory.aspx?id=808
CO49+AFC is an improved version of FFT-TV, with Automatic Frequency Control (AFC). This version is especially recommended for use with transceivers without TCXO`s or OCXO`s. Without AFC, hues in the received FFT-TV picture are very sensitive to frequency drift in the transmitter and/or receiver. With AFC, the receiver software locks to the pilot carriers sent along with video via the transmitting software (the new software is required for both transmitting and receiving). The effects of frequency drift are thus compensated as the receiver software tracks the transmitted signal. Download the .zip file to a folder where it can be unzipped, and from which each application can be opened. CO49+AFC.zip contains the following files: README49B.txt, TXScreen.jpg, RXScreen.jpg, TXfftCO5D.exe, TESTPATT.ini, RXfftDIFF7F.exe, RxReplay7A.exe, and PTT Toggle.exe.

The "CO49-Voice" folder provides an introduction to "SSB plus Video", an experimental mode providing simultaneous voice and video over HF. Instructions are provided for building an SSB Audio/Video Processor, a device that connects between your PC and soundcard interface. The video may be conventional analog SSTV, or a special version of ZL2AFPp`s "FFT-TV." FFT-TV is sent and received at 1 frame/sec, and an application is provided for playing recorded video clips back at up to 10 frames/sec. For FFT-TV, you`ll need transceivers with TX and RX bandwidths of 3.5 kHz or more. Software for FFT-TV is included in this folder. The zipped folder contains 23 files, so you`ll want to download to a folder where it can be unzipped, and from which each application can be opened. Read the .txt file "SSB plus Video Info" first.

FFT-TV.zip

http://www.hamsdr.com/personaldirectory.aspx?id=165
The original CO49 version of FFT-TV, developed by Con Wassilieff, ZL2AFP, is a Windows soundcard application. FFT-TV sends and receives "live" full-color video (at 1 FPS) or AVI color video clips for playback at 10 FPS. FFT-TV is especially robust under HF multipath propagation conditions. Because AFC is not included in the original FFT-TV receiving software, SSB transceivers with very low frequency drift are required to maintain proper color. If your SSB transceiver can be used for PSK31 (with AFC disabled in the PSK31 software), it is probably stable enough for FFT-TV. Full documentation is provided in the README49.txt file supplied with the software package. Download the .zip file to a folder where it can be unzipped, and from which each application can be opened. FFT-TV.zip contains the following files: README49.txt, TXfftCO5.exe, TESTPATT.ini, RXfftDIFF7.exe, and RxReplay7.exe.

"HF5B EZNEC Model.txt" is a text file describing how QuickSmith and EZNEC 5.0 are used to model the Butternut HF5B two-element, 5 band beam (driven element only). The method sums two rectangular hyperbolae at three frequencies to obtain operation on three amateur bands (20M, 15M and 10M for the HF5B). This method can be used with any dipole resonant at a frequency between the lower and upper bands of interest (25.8 MHz for the HF5B driven element).

"JI3GAB DSP-SSB Notes.txt" is a text file describing how to set up and run JI3GAB`s software for SSB generation and detection. JI3GAB`s Java software uses the computer`s soundcard to generate and detect 12 kHz SSB with any transceiver equipped with a 12 kHz last IF (such as the PSK-10-SDR in the "PSK-10-SDR Mods 1.txt" file listed below). The "TX-RX Batch Files 1.txt" file (listed below) provides a convenient method for switching the DSP-SSB software between transmit and receive modes. JI3GAB`s GUI version of the original Java software is described in "JI3GAB DSSBP Notes.txt" listed below.

The PSK-10 is a transceiver kit for the 10M band available from Small Wonder Labs. Originally intended for PSK31, it can be modified for general SDR use. By adding a 12 kHz IF input and output and increasing the bandwidth from 3.5 kHz to 5.5 kHz, various software-defined modes can be implemented, such as SSB and ISB. The "PSK-10-SDR Mods 1.txt" file provides details of the PSK-10 transceiver modifications. Figures accompanying this document are found in the "PSK-10-SDR Figures.zip" file (listed above). After completing the modifications, the PSK-10-SDR transceiver should be tested using the procedure given in the "PSK-10-SDR Test.txt" file listed below.

"RxReplay7A.zip" is a special version of the program used to play back ".49" FFT-TV files. After unzipping, RxReplay7A is used to copy each image in a ".49" file sequentially to the Windows Clipboard. Other applications (such as AVI Constructor) can sequentially auto-paste each image from the Clipboard for further processing (such as constructing an AVI file). The resulting AVI file can be processed by a frame interpolation application (such as MotionPerfect). This process allows "live" video transmitted at 1 FPS to be viewed at smoother, more natural, frame rates up to 10 FPS. Note that this additional processing applies only to "live" video, but is not required for AVI video clips (although AVI clips are also transmitted at 1 FPS, RxReplay7 will play them back at 10 FPS, without further processing).
