PocketDigi-1.0.6 - MFSK for the Pocket PCPocketDigi is a digital teletype software for
Pocket PC platform. It has been ported from gMFSK by Tomi Maninnen, thanks
Tommy! It meant mostly to rewrite all DSP algorithms to fixed point and
rewriting system calls from Linux and gtk The project including desktop windows test application and sources may be downloaded from http://sourceforge.net/projects/pocketdigi/ The program is discussed on http://groups.yahoo.com/group/hampocket/
This version supports MFSK16. The decoder is about 1dB worse in white noise than Nino IZ8BLY's Stream software. The implementation is pretty efficient, it generates a CPU load comparable to the PSK31 decoder. I hope to get reports on the usability of it. I know there are lot of things to improve. The winters are long and cold, improvements are to be expected until spring. There will be a gathering of OK-QRP club on 17 November. I hope to manage to presuade some colleges to build a small digital QRP TRX as a companion to PocketDigi. DDS driven MFSK16 transceiver with E-class PA would be a perfect QRP solution and the TRX may not be bigger than my iPaq. Excerpt from ChangeLog: - Initial MFSK16 implementation. Tuning arrow shall be pointed to the
idle (zero) tone.
