During the last days with my friends not available for our daily skeds on 80 m
(3581.5 + 1500 Hz) at night I tried 20 m, 30 m and 40 m. The results, however,
were pretty bad:

Still lot of activity around 2100 UTC or later on 20 m and lower, but nobody in
Olivia. There was nobody on the frequencies announced here on the reflector on
20 m.

The same on 40 m, with only one (EB5DET) anwsering one of the many CQ's there
(just above the PSK activities).

On 30 m more than 200 Hz bandwidth is not allowed in Region I below 10.140,
therefore I called here above the PSK-frequencies as well to allow others to
find the signal in the waterfall.

I wonder where all the group members are ... In order to keep Olivia alive it
would probably quite helpful if there are others which would be qrv in Olivia
and enjoy the benefits of this excellent qrp-mode!

73 and see you in Olivia again!

Hello to All

There is always some activity on Olivia on all bands.
On 20m I have everyday my qso around 7:30 to 8:00 UTC
with Dick 3D2BA with Mode Olivia 1000/32
Or on 40m as well as very late on 80m
Seems due the fact that everyone thinks the condx are bad,
they have stopped to listen, or even calling cq..

Hello

Is the one mode community enough vital? Or to expand the modes and
shrink the formats?

The practice show that Olivia 500/8 equal by snr with MFSK16.
The MFSK16 wpm=57.8, BW=316Hz and have pic-mode. So the only -3dB better
normal speed Olivia format 500/16 wpm=19.5
If we seek downward 3dB by snr, then there are DominoEX8 wpm=58, BW=346
or DominoEx 4 wpm=29 BW=173Hz!

So if we are use these 3 modes as default on the Olivia channels we
expand our freedom.

Topics for discussion:
1. To stop using 1000/16 format
2. To turn every 1000Hz channel for 2x500Hz channel so the left is for
500/16 and right for MFSK16 and DominoEX 8
3. To use in format 500/16 channels for more freedom  so MFSK16 and
DominoEX 8
3.1 with 500/16 format channels we use the default switching procedure
Default answer in  same mode/format as calling, but we know, that
possible to take account the propagation and answer in different mode:
a) poor conditions answer Olivia 500/16
b) normal conditions answer MFSK16
c) good propagation answer DominoEX 8

There's more to it than just published S/N figures - some of which are doubtful.

After considerable operating I think it makes MUCH more sense to stop using MFSK
period. It makes much more sense to use Olivia 500/4, 500/8, 500/16 depending on
what the signal level is - the better signal the LESS tones and thus more speed
(and less robust).

Also promote Olivia 250/4 which, under real condx, is almost as good as 500/16
AND the same speed. And of course half the bandwidth.

I've had dozens of 500/4 and 250/4 qso's and both are excellent.

I think MFSK should be discouraged as much as possible because it has no great
advantage to any of the Olivia modes or DominoEX AND it is more difficult to
tune.

DominoEX (and with FEC) is another matter especially on higher bands under
moderate to better signals it is a preferable substitute because of ease of use
and bandwidth.  Still. it is not as robust as Olivia, but a secondary mode for
sure that can be useful under crowded condx.

I also see little or NO advantage to the 1000 or 2000 hz Olivia modes except
that many stations, especially DX, on 20mtrs think it is magical and don't even
listen more the less narrow modes. I don't think they should be banned or
derided - just NOT promoted.

Lastly, I think an Olivia forum should promote Olivia.

Incidentally, some stations seem to think there is little Olivia activity.  In
the last year and a half I have had 1,076 Olivia QSO's (160m-6m( - not more than
10 via schedules or web pages with minimal antennas and 50w or less.  I did NOT
do it, though, by listening ALL the time or by spending all my time on PSK and
RTTY.  Also, amongst the 1,076 qso's were over 120 ragchews lasting 1 hour or
more and a handful of ones lasted over 2 hours.

Right now activity level on ALL modes are low on 40mtrs on up but Olivia is
alive and well for those who actually use it and don' give up easily.

I don't have much trouble tuning in a MFSK signal either though it is easier if
you use AFC - then two people dance all over the place and change freq like
PSKers.

BOTTOM line - if you get a fraction off of a MFSK signal it will not decode.
With Olivia you can get 30-50% off the signal and still decode
and AFC doesn't apply.  It is more critical and that is why you keep reading
statements of that sort.

MFSK, in my opinion, is an obsolete mode with Olivia and DominoEX and DominoEX
FEC. And if your main concern is speed, DominoEX can provide that and still
outperform MFSK under real condx. And Olivia 500/4 (abt 40wpm not quite as fast
as MFSK) is still a better choice than either.

With Olivia 500/4, though, you want to increase your Sync Depth Integration
setting to get it's full benefit.

Thinking I need to use these lower tone-count variants (250/4 and 500/4) a
little more and see how they perform. Thanks for the nudge.

I've been using a tune margin of 8 (for tone frequency spacing) and an
integration period of 4.

Can you describe a bit more what you might use as far as integration periods
in various band conditions and why? How far do you go, and what are the
trade-offs?

I see there are 125 Hz permutations in addition to the 250 and 500 Hz modes.
As well as 2-tone variants. Is there a chart somewhere that might speak to
the strengths and weaknesses of these various mode choices in differing band
conditions?

TIA

An Olivia contest might help increase activity but I'm not sure if personally I
like the idea.

Of course, we could have the contest on 2000 hz mode and do like the RTTY guys
and all run KW amps and swamp the entire data band for a whole weekend! That
would get some attention. I guess if contests are accepted as being OK to jam
entire bands (on other modes) for days at a time - why not Olivia?

Now, that last paragraph definitely is sarcastic and I admit it. Having got that
out of my system .... an Olivia contest limited in time and space still might be
worth the effort.

We had this PSK125/250 contest some weeks ago and I have seen a lot of activity,
therefore a contest in 250/8 or 250/4 could be a good way to increase activity
in Olivia as well. A year ago there was a DRCC contest even in JT65 (!), and
might be an Olivia contest could be organised the same way (I will try to
forward this e-mail to Andy, K3UK).

There is a lot of Olivia activity on 80m in the evening (3581.5 khz +), but as
mentioned before, there is a lot of activity in PSK on 40 and up but - at least
in the evenings when I can be qrv during the week  - nearly nil in Olivia. This
means on 80 m Olivia has been some how established already. If we would like to
see Olivia on a similar path as PSK (not so much activity years before, only a
little bit on 20 m, but now quite popular on all bands) than a certain level of
activity is necessary to get others interested in trying this mode. This
activity should continue for 24 hours (as long as bands are open) and not only
be limited to skeds with friends we meet quite regularly.

Thanks for reading, and hope to meet you in Olivia!

Not that I prefer one mode over another, but with all the choices, it
seems like digital soup with multiple modes creating more confusion
than one clear cut choice. If the signal is below the noise, and
unviewable on the waterfall,
wouldn't the mode with the less critical tuning be a highly desirable choice ?

Just Wondering

One way to increase Olivia activity and improve your Olivia QSO count is
to let people know what mode you are operating and on what band.

Head over to the HamSpots.net pages. There is a page setup for Olivia
modes. The Hellschreiber ,30M and Pactor groups are very active with
their own pages and use the site to schedule contacts, spot interesting
activity, experiment with different modes, etc.

Selfspotting is allowed and encouraged. It is an easy way to let people
know what you are doing or who you are seeing on the bands.

There are no real restrictions on what you post. Use it to help make
those Olivia contacts.

The Olivia page is at this link...  http://www.hamspots.net/spotit.php?g=o

HI Juergen   - in relation to your comments I would note that I can
often find 1000/32 Olivia on around 3596.5 dial USB in the evenings (SSB
permitting) and also lower down in 500/16 around 3583 USB.  7 MHz has
been less successful at present. What will happen on 7 MHz after 29th
March under the new band plan will be interesting to observe.  I am not
keeping my breath held though!.

We now have permission in EI for data modes operation on 10 MHz  above
10140 from 29th March provided the bandwidth is a max of 500 Hz -  that
will allow a little more activity from EI when the higher bands are
dead. I will be looking hopefully for Olivia activity there.

As a general comment it would help greatly if there was some agreement
on a channelised approach to operating Olivia.  Its very convenient to
be able to scan rapidly through fixed channels without tuning around.  A
channelised approach would also help in reducing adjacent channel
interference.

If I am running one of the standard Olivia modes I usually run the Sync Integ.
Period at 3, 4, or 5 depending on if the signal is extremely weak "GHOST" like
or better hi hi

BUT if I decrease the tones and run 250/4, 500/8, or 1000/16 I DOUBLE the sync
int. period to 6,7. or 8

If I run 500/4 or 1000/8 I go even higher such as 10, 11, 12, or even higher

I see very little disadvantage to using 250/4 mode when I set the sync int
period between 6-8 as compared to 500/16.  It is nearly as good under all condx.
And of course the speed is the same on both BUT you save half the bandwidth. 
One disadvantage that PROBABLY exists though is that when you go to ANY more
narrow mode you are more succeptable to QRM right on top of the signal.  I have
copied 500/16 real well with a PSK sig right on top of moderate strength BUT I
think you would have less luck on 250/4 if the PSK stn was on top of you hi hi

500/8 and 500/4 are only slightly less sensitive that 500/16 if you up the sync
int period as noted above.

Of course, you could go the opposite way to 500/32 or 500/64 and it would be
even more sensitive BUT the speed would be SLOWWWWWWW!

I think the order of use I would like to see is :

1. Weak sig - 500/16 or 250/8
2. Moderate sig : 500/8 or 250/4
3. Strong sing 500/4, 250/4, or even DominoEX if you can really type that fast
which I can't hi hi

BTW, a few weeks ago there was a contest on and RTTY was blanking the 80mtrs
data band. I had a 250/4 ragchew QSO sandwiched in between the RTTY contesters
for abt 55 minutes. Doubt if hardly any other mode could have done that except
250/8 and it would have been slower.

I have noticed NO speed increase from going to 4 tone to 2 tone. There may be a
miniscule increase BUT I time my macros and some long macros too and see NO
speed diff between 250/4 and 250/2 or 500/4 and 500/2 - never tried 1000/2
though suspect it is the same as 1000/4.

Not sure there is any benefit to 2 tones but would like to hear other opinions.

Yes, I agree and I think Olivia IS the easiest to tune in - certainly NOT MFSK.
And when you can barely see the signal on the water OR not at all you can set
the Search setting in Olivia to 8  and click on the water fall and make a guess.
You don't have to be close to get a decode on Olivia.  On MFSK, PSK, and many
others you have to be much more precise.

My question is WHY don't you prefer one mode over the other? If a mode is
clearly superior in terms of getting through and is suitable for my type of
operation (ragchew or DX) than I prefer it. Which is why I generally prefer
Olivia. Perhaps if I ran high power and had a tower and huge arrays of antennas
I might feel different though because perhaps any mode would work well for me
most of the time. Or if all I cared about was contest like short exchanges I
wouldn't care either perhaps ...

Hi Gerry,

500 Hz are the max. allowed below 3600 according to Region I bandplan, therefore
I use 500 Hz and lower, mainly around 3581.5 khz dialing frequency and around
+1500 Hz. This is just above the frequencies where you normally find the PSK
users. There is a lot of activity (by the way: we met there as well on Jan 13),
and therefore I don't see to do something special to increase the Olivia
activity. Regardind 7 and 10 Mhz we have to see if activity will really increase
to the same level as PSK has now. I personally don't believe, however, that this
will work despite of all the benefits such an approach would have. If there will
be some convention then people might follow at the end (on 80 m, for example it
seems to work, because many users try to pay attention to frequencies which are
in use already and set their audio frequencies close to the other user, but it
depends on the first one who shows up ...).

Thanks for the link, Laurie. I will give it a try. The only problem with
specialized web sites is the fact that the spots are not distributed via the
other DX-Clusters. This happened with Andy's K3UK digital cluster as well, and
at the end it was no success. The best is to spot somebody in a standard cluster
if you see somebody and then activity will increase at least for some time after
the spot.

To give you an example: I called on 30 m for about an hour until YV5KAJ showed
up at the end. I sent a spot, and after some time others did show up and called
him.

By the way: my intention is not to have more qso's for myself (this is a side
effect) but to increase the activity in Olivia because I strongly believe it is
an excellent qrp mode and should deserve much more attention as it has right
now.

Another information: Andy, K3UK, is presently reviewing how he could set up a
contest in Olivia. I suggested him to look for a Saturday and a time between
1200z and 2400z. If there are other proposals please send an e-mail to him
yourself (or to me and I would forward the comment to him). You find his e-mail

One, I don't want to disparage anyone's favorite flavor of digital
modes, but the main reason is that I have yet to make a contact on
digital modes other than RTTY and PSK-31.  I saw the QST article, so I
joined this group to learn.
I don't have any antennas up at the present, but I have a new radio
and a SignaLink USB and I have the parts for the antennas. Just need a

Hello all
We use often 80m (3590 kz) Olivia 16/500 and when condx going very poor then 8/250. There are a few OH stations and sometimes DL fellows too. Almost every evening our ring is active. When condx are better we use ARQ modes like PAX, PAX2 and ALE 400 links. We had noticed that Olivia worked there difficult 80m band when other modes failed.

Hello All

I am using Olivia right from the start, when Pawel invendet the mode..
Pawel is living almost next door to me here and we often discuss digital modes.
I was also together with Nino and Murry when MFSK16 started.
The same goes with PSK which we first started without soundcards but with
a Motorola Evaluation Kit, later also MT63 with the same Kit.
Peter G3PLX wrote those programms, after a script from Pawel, the autor of Olivia
All those and many other modes work fine and are realy very interesting for hamuse.
But beside a good ARQ mode like Amtor, or Pactor 1-3, Olivia is the best and most robust.
Regardless, whats written about S/N ratio or else, all the Olivia  Settings have their
advatage. One needs only about 40 -50% of the channelwidth to get a 100% copy with very
low signals. Therefor how wider, how more robust. I can work a S1 Dx Station in a RTTY contest
with up to 3 RTTY or any Pactor station inside the Olivia 1000/32 channel. I did that many time,
again just resently with my qso partner 3D2BA on 20m.
There is no NO-ARQ mode, which could beat that, any MFSK16 signal would missprint at the first,
qrm sign inside the channel, not so Olivia.
The small modes like 500/16 or 250/8 are also very good and suitable for bands not allwoing wider modes.
But as said how smaller the channel width, how less robust is the mode.
I made the last few years, so many experiments with Olivia and other modes, and realy find, its the most useful
mode for DXing, its not to far of from JT65, but still faster.
So take in account the facts, that how smaller the bandwidth, how more senstitieve for adjecent, or direct qrm.
I know, this may steer up a discussion again, but for me as a believer, and heavy Olivia user, this are the facts.

Tommi, did you have experience with DominoEX?
Or with the new version of DEX with FEC, the Thor?

Hello

Yes we have tested also DominoEX, also with FEC and THOR. They are quite
good modes, but they are not so good as Olivia. DEX and Thor are quite
bit faster and working when condx are quite good. But when aurora,
multpath, flutter, QRN, QRM comes (often 80m) then these modes failed.
Olivia is last mode which can get Qso made when condx are vy poor.
