This is a
Windows-based software
assisted radio for weaksignal SSB and CW work. Although it can be used
with a standard soundcard, it is best with a high performance high
sampling rate card and radio hardware that has I & Q outputs. Thanks to Jeffrey Pawlan WA6KBL for his advice during development. |
| an experimental Software
Defined Radio,
with AM, ECSS, SSB and FM demodulators, with a highly graphical
interface
|
|
| |
|
| a keyboard-to-keyboard communication program, tailored
for very low S/N ratios, based on the IFK
technique, using only 4 Hz of band. The IFK technique was first described by Steve Olney, VK2ZTO |
|
| |
|
| a QRSS/DFCW
viewer, especially tailored for LF, but usable also for EME
For a primer on QRSS, look the link above, on the very informative pages of Rik, ON7YD or 'QRSS and You' from Clint, KA7OEI |
|
| a spectral analysis program, with audio filtering,
originally born for EME usage, but useful for many other purposes. An example of use for NDBs reception can be found on this page by KA7OEI |
|
| |
Two Tone Tester (T3) , a combination of spectrum analyzer and audio generator (with optional quadrature outputs), useful for many purposes |
| a DOS program, which *requires* an old ISA original
SoundBlaster card, similar to SPECTRAN in functionality, though not quite as powerful |
|
| a DOS program
that interfaces with a DSKC50 DSP board, implementing
an audio filtering unit, with denoising, variable bandpass, auto notch , AGC |
