Folks,
Given the recent discussion in the USA about restriction of audio
subcarrier generated digital modes (i.e. most of them!) to 500Hz
bandwidth, perhaps now is the time to remind you about -
DominoEX DominoEX DominoEX DominoEX
Yes, this super mode, which has all the advantages of MFSK16 with none
of the disadvantages, meets these requirements easily at 16 baud
(355Hz BW).
DominoEX now sports FEC (same technique as MFSK16), and performance is
within 2dB or so of MFSK16. The major advantages are improved
tolerance of multi-path and Doppler effects, and the impressive
tolerance of drift and poor tuning.
DominoEX with FEC is now available in MultiPSK by Patrick F6CTE and a
new alpha version of ZL2AFP DominoEX with soft decision decoding. This
version is a small program which will operate on older slow laptops.
Without FEC, DominoEX is also available in gMFSK.
