- 1992 QST Magazine article "Low Cost Digital Signal Processing for the Radio
- Amateur" by Dave Hershberger, W9GR. These programs are not public domain

- The QST Magazine article cited above describes a TMS320C10 based hardware
- platform upon which this software runs. The hardware goes between a
- communications receiver and a loudspeaker, and includes its own 1 watt
- audio amplifier. The hardware is available in kit form (a printed circuit
- board and all components which mount on it are included but no enclosure or
- power supply is provided). The kit is available from:

- One final note: even though the QST article mentions that these files may
- be found on COMPUSERVE, and even though I am listed as a COMPUSERVE member,
- I almost never check in to that service. So if you send me electronic mail
- via COMPUSERVE, I may not get it for a year (really)! But you CAN send me
- e-mail via internet, which I check regularly. My internet e-mail address is
- dlh@gvgdsd.gvg.TEK.COM and it is possible to send e-mail to internet from
- COMPUSERVE (but don't ask me how).
