Subject: Re: [digitalradio] Is PSK
superior to Olivia?
PSKmail has 0% garbage, and fills in the deep qsb we have here. I have
tried MFSK, but where PSK does not come through anymore, MFSK cannot do it
either.
I have 6 weeks experience now with a steady pskmail link to the internet
via SM0RWO, 2200 km from my portable qth in Spain (fishing rod with wire on
top of my RV). The average throughput has been 40 wpm (including qrm, radar,
jamming, qsb and what have you) with 0% error, within a 100 Hz bandwidth.
PSKmail will just slow down and reduce block size automatically when trouble
arizes.
I can assure you Olivia or MFSK can not do this. I have even been able to
work through olivia qso's bluntly started on top of our qso. And can you show
me how to do a Google search with your Olivia machine?
By the way, in keyboard mode pskmail gives you psk31 speed with 0%
errors...

My experience has been that Olivia is better under weak signal
conditions. Slower and '"wider" but less missed/garbage
characters. Also a little easier to "spot" a signal in the
waterfall that can not be heard by the ear because it is wider.

Maybe my equipment isn't set up right to discover the Olivia
advantage.
I have been running Olivia for a while, but I have not
found any
advantage over BPSK or QPSK. Note: I have not done any
testing, or
side-by-side comparisons... just regional and DX QSOs
near the noise
floor.
Olivia requires more bandwidth than
standard PSK31 or PSK63.
Even a standard PSK31 seems to get through
as good or better than what
I've found with Olivia. PSK63 seems
plenty fast enough for most
keyboarding.
