[digitalradio] Olivia vs. RTTY vs. PSK spectrum efficiency
I'm sure no one purposefully opened fire on your frequency. NAQP contest is a rapid-fire sprint-like contest with lots of passing/QSY's. It's also likely that whoever started the CQ didnt hear you or the station you were working at the time. Olivia uses a lot of bandwidth for it's speed and is an extremely weak-signal mode. That's great for what it is, but fairly incompatible with a crowded band where efficiency is required. Quite frankly, RTTY could easily be replaced with PSK63 as the prime digital contest mode. However, many PSK operators are so clueless and often downright rude when it comes to contests that its an extremely uphill battle. We could fit a lot more PSK63 signals on the band than RTTY... It would be interesting to see what happened if a semi-major RTTY contest was moved to PSK63 only. 73, Ty K3MM Jul 18, 2010 11:28:11 AM, digitalradio@yahoogroups.com wrote: I had 3 interruptions from 3 different stations during an Oliva 8/500 net last night on 80m within about a 5 minutes timespan. And, BTW, I know for damn sure they could see and hear my signal as I switched to RTTY at 50w on all stations and repeated the frequency is in use until the moved. I don't think anyone should suggest limiting to contests to fixed frequencies, but it damn sure would be nice if some of the mindless RTTY contesters would start showing some common courtesy by listening a second or two before stomping on QSO's in progress. -Dave, KB3FXI --- In digitalradio@yahoogroups.com, g4ilo wrote: And the hundreds of people who take part in the major RTTY contests would all operate on three fixed frequencies how, exactly?

The only activity I've found has been on 7.038.250 +/- PSK MFSK etc., and using 250/8, and the very few stations I have worked on 40m have not worked anyone on .043 ! Is 7.043.250 still valid for Region 1 3 or infact anywhere ? Is there anyone out there actually using 7.043.025 ? If not, then can anyone let me have the WHAT, WHERE, and WHEN regarding 40m Olivia activity, please. Cheers 73's Dave, G3ZXX.

[digitalradio] Olivia Frequencies and Modes Re: NEWBIE QUESTION FROM AC5JV
Hi Bonnie, some comments from my experience. I have tried your proposed frequencies for Olivia and they are ok, more or less, but: 10142.5 will have the DK0WCY beacon directly fall into the Olivia signal, therefore I prefer the 10141.5 which is given in your plan as well but not as a center of activity. I suggest to review this situation. 7042.5 is not very well accepted as Olivia center of activity. A much better choice is to go to 7035.5 or 7036.5 just above the PSK activities (see another reply from you as well). Don't forget the 3581 khz USB (+1500 hz), also just above the PSK activities on 80 m. I was very lucky last week to have a qso with VE1CDD on that frequency in Olivia 16/500 (around 0030 UTC or so, don't remember exactly) with only 10 W into a 32 m longwire. 73 Juergen, DL8LE --- In digitalradio@yahoogroups.com, expeditionradio expeditionra...@... wrote: Hi George, http://hflink.com/olivia The most common flavor of Olivia is 500/16 and for DXing, you can find it on one of the following USB VFO Dial frequencies: 7042.5 USB 7072.5 USB 10142.5 USB 14075.65 USB 14074.65 USB 14077.65 USB 18102.65 USB When Olivia first began, the 1000/32 flavor was much more common, and it is still fairly active in europe and some other parts of the world on these USB VFO Dial Frequencies: 14105.5 kHz USB 14106.5 kHz USB For more complete information on Olivia Frequencies and modes please see the website: http://hflink.com/olivia 73 Bonnie VR2/KQ6XA AC5JV,GEORGE wrote: MY QUESTION IS WHAT MODE IS USED THE MOST ?

[digitalradio] Olivia Modes/Flavors/Bandwidths/Speed Re: NEWBIE OLIVIA QUESTION
Hi Warren, When Olivia first became somewhat popular, it was mode of the month... there was a lot of experimentation with tones and bandwidths. Operators found advantages for various conditions and needs, with extremes of each flavor. The 2000/64 is quite good for interference rejection. We used it on 40 metres to work through strong shortwave AM broadcast stations that used to be around 7105-7125 kHz. You can QSO with Olivia 2000/64 signals in the midst of S9+ broadcast music interference, without using a narrow passband filter. Just tune your VFO dial to about 500Hz above the broadcast station's carrier frequency. Not many digi modes are capable of that level of performance, even with a lot of help from narrow filters. But, the 500Hz 16-tone flavor of Olivia ended up becoming popular... not really because of its technical superiority over the other flavors... it is mainly because it is the best compromise for weak signal and fast enough keyboarding speed, and still fits within the IARU regions' bandplans 500Hz bandwidth segments. Operating near where RTTY/PSK/other modes are normally found increases the chances for random QSOs and responses to CQs. 73 Bonnie VR2/KQ6XA K5WGM Warren wrote: has anyone tryied to push the max tones to 256, like 2000/256?

This no doubt has to do with symbol rate etc (experts comments welcome). Reducing the number of tones by half will yield 1-to-4db better weak signal performance, but at the cost of slower wpm rate. The nice thing about being able to change the configuration is that it lets you try different combinations to squeeze the most out of the modes to suit conditions. The modes with the higher tones are extremely sensitive so the skies the limit in terms of weak signal work as long as you don't mind the slow pace. It pays to take a good look at each configuration and compare; for example; Conestia 32/500 mode vs. Olivia 16/500. The Contestia mode is 5 wpm faster and slightly more sensitive than Olivia. This simple change lets you pick-up the pace without sacrificing weak signal performance. For those who are conscious about spectrum; take a look at Contestia modes 8/250 and 64/1000Hz. They both have the same wpm speed and nearly the same sensitivity, but the 8/250 mode performance is the same and it does it in 1/4th the bandwidth. Getting late here so will have to wrap it up and let the group look at the figures and send some feed back. Hope you all find it interesting... Tony -K2MO

Re: [digitalradio] Olivia
I think that the reasons that we tend to gravitate toward a given Olivia speed/bandwidth: - need a standard to find others on the air. It is easy to determine the BW, but not so easy for the number of tones. - if you use a non-standard speed to start with, you will have a difficult time finding anyone at all (speaking from experience, HI) - once you make contact, switching to different speeds/modes is not always that easy to do with some operators - it is probably best to start off with a robust subset of a mode and go faster if you need to do this, with the plan to return to the robust mode if faster ones don't work, but it can be a bit awkward - operators who have slower keyboarding skills have told me that they find that the 19 or 29 wpm of Olivia 500/16 and 500/8 to be a good fit - I can see where the slower modes of Olivia can be useful for really difficult conditions such as short DX type contacts or for critical public service messaging, but for casual use, the faster Olivia modes may not work as well as other modes, particularly MFSK16 which is also much faster (~ 40 wpm) Also, it is possible that eventually someone might be willing to come up with a program that will use a protocol that can adapt to conditions. Simon mentioned WINMOR which is the only possible protocol that can . This is the serious shortcoming of sound card modes thus far since nothing currently available can automatically scale speed and robustness to meet conditions. The closest thing we had for a short time was SCAMP and the ratio of speeds was fairly limited due to not being very robust at the slowest speed. But WINMOR should help a great deal in moving the bar higher. But from what I can tell, the WINMOR program from the developer is not intended to be used peer to peer, only for e-mail. That won't help most of us who are primarily interested in public service/emergency communication between operators at various locations. As some have found out the hard way, you don't design service/emergency communications to be sent via e-mail since you make a very dangerous assumption that the internet will be operational.

Re: [digitalradio] Olivia
Rick, It is easy to determine the BW, but not so easy for the number of tones. The RSID would come in handy for this, but I don't feel it's difficult to determine the number of tones. The 500Hz mode seems to be the standard and it's rare to see anyone using more than 16 tones. Clicking through 8, 4 and 2 tones will usually find the correct combination quickly. operators who have slower keyboarding skills have told me that they find that the 19 or 29 wpm of Olivia 500/16 and 500/8 to be a good fit. I agree - the 500/8 mode strikes a good balance between speed and throughput under most conditions. I asked Simon to include 500/8 as one of the point-n-click modes in DM780. the faster Olivia modes may not work as well as other modes, particularly MFSK16 which is also much faster (~ 40 wpm) True - cutting the number of Olivia tones will cause a slight degrease in the robust quality of the mode in exchange for speed. But there are times when this will not effect throughput, i.e., moderate to good signal quality / stability. Re: Winmore I'm not so sure that this mode can compete with robust MFSK modes like Olivia. As you say, it wasn't intended to be used as a chat mode so it seems we might be mixing apples and oranges by trying to compare the two. Thanks for the comments Rick...

Re: [digitalradio] Olivia
I've found the 1000Hz 8 tone waveform to be very good also. Nice throughput and still plenty sensitive enough for many conditions. Had a nice chat to KC5CAY in 8 tone Contestia today and that worked very well, if a little fast. I have the radio on 14072.5 USB if anyone wants to experiment with any of these modes.

Re: [digitalradio] Olivia
Rick I feel you think that winmor was intended to be a chat mode. It was not and is not nor a replacement for pactor. John
Re: [digitalradio] Olivia
Hi John, WINMOR is an open protocol, therefore it is up to the developers as to what they want to use it for. I personally prefer open protocols because of this, but far be it for me to tell others how they can or can not use a given protocol. The current developers have designed the protocol to compete with Pactor modes. Preliminary information says that it will outperform Pactor, and be fairly competitive with Pactor 2, although at a much wider bandwidth, similar to Pactor 3. Unlike Pactor, WINMOR will have the ability to work within 200 Hz, 500 Hz, and ~ 2000 Hz bandwidths so that it can be used within the IARU band plans. And unlike Pactor 2 and 3, the modes are not including PSK100. We know that PSK modes are susceptible to ionospheric instabilities, particularly if they do not have training pulses. If you have looked at the very interesting mode specifications, WINMOR may have some of this newer technology. I have never seen any tests from SCS as to how much ISI/multipath or Doppler the Pactor modes can tolerate, but I suspect not very much. (Dr. Rink claimed some years ago that it could handle most paths well enough with their DSP, but I suspect that there are cases where the signal strengths are good but Pactor can not work and yet other modes can. As it progresses over the years, there is no reason that WINMOR can not be constantly improved. Unlike a proprietary lock in with a hardware/firmware system, it would be possible to update to newer modes just by downloading new free software. In fact, I would expect that to happen. While I don't see hams using it for casual chatting, but it could be done similar to how we used to use Amtor and even Pactor in the old days, HI. What I would like to see is the ability to have a superior ARQ sound card mode that can scale speed up or down to meet conditions and do this automatically without user intervention. Since one of my interests is pubic service, if peer to peer connections were designed into the software, you would be able to connect to another station under varying conditions and communicate directly from keyboard and send files as needed. Ability to connect to an e-mail server may be useful, however the first two needs must be met to be of value for local and regional digital communication. And that is something we don't have available to us at the moment. 73, Rick, KV9U John Becker, WØJAB wrote: Rick I feel you think that winmor was intended to be a chat mode.

[digitalradio] Olivia Contest Apr 19, 2009 : Piggy backing on TARA Skirmish
I received a few suggestions about again sponsoring an Olivia contest. Here is what I am suggesting. The TARA Skirmish is scheduled Z-2400Z, Apr 19, Olivia is a permitted mode. I suggest that you work the TARA contest AND between the hours of 0200 and 0500 and/or 1400 to 1700 you make a special effort to work the TARA Skirmish using Olivia. When the contest is over, extract your Olivia modes contacts during the suggested hours and post your olivia scores to http://spreadsheets.google.com/viewform?formkey=cFdSS0Exb1hJRWhnV04yb214Q2hCZlE6MA.. This way, we can support TARA and have a Olivia contest at the same time. Please also post you total score to TARA http://www.n2ty.org/seasons/tara_dpx_rules.html The idea of just two three hour periods is so as to focus activity. last time we had an Olivia contest over a 24 hour period, there was so little activity everyone gave up.

So why a weak M after the call sign? 73 Patrick - Original Message - From: Steinar Aanesland To: digitalradio@yahoogroups.com Sent: Sunday, January 04, 2009 12:51 AM Subject: Re: [digitalradio] Olivia 8 x 250 / psk31 / MFSK 8 503 CENTER BEACON - RUNNING NOW - 1615 HRS Hi Graham Here is a screen capture from Norway . 73 de LA5VNA Steinar moz-screenshot.jpg

[digitalradio] Olivia Article in December QST
Article about Olivia digital mode slated for December QST magazine Posted by: garylinnrobinson [EMAIL PROTECTED] garylinnrobinson Date: Sat Oct 25, 2008 3:33 pm ((PDT)) For anyone who may be interested there will be an article in the December 2008 issue of QST about the Olivia digital mode. It is a general information article and it is hoped that it will help create more Olivia activity on the ham bands The article is called Ghost QSO's -- Olivia Returns from the Noise Subtitle Olivia -- the magic mode Worth reading (though I'm biased since I wrote it) if you are at all interested in quality digital qso's! Also - On my web site I have posted versions (based off of FLDigi 3.03AB) of FLDigiROL - my own modified version. There are binaries for WIndows, Linux (compiled on Kubuntu 8.04), and source code available. These are beta versions and have very little in the way of documention hi hi! They will be updated in the future when FLDigi stabilizes and not so many bug fix and updates come out so often. I have made modifications and added features that suit me so it may NOT suit anyone else's taste. But they are available for anyone to look at on : http://home.roadrunner.com/~rolswana/
[digitalradio] Olivia Signal?
Just curiosity Can anybody identify what mode is using a signal on 3.733 (80m). I am trying to decode digital sstv on that frequency, however most of the time I hear a clicking multitone sound like Olivia sending beacons, maybe trying to establish a connection, it keeps transmitting multitones for a while, sometimes more than 2 minutes, making my decoding a mess. The beacon of the signal usually starts with several digital carriers sweeping in frequency on the waterfall, large bandwidth and when transmitting the multitones make a characteristic picture of small squares like a chess board, I don't see any pilot carriers.

[digitalradio] Olivia mode performance
All, Certainly is remarkable the way Olivia mode performs under adverse conditions. Was having trouble decoding VK2PN in PSK31 mode due to the unstable conditions at the time (selective fading / multi-path). Switching to Olivia 500/16 fixed the problem. Copy went from marginal to perfect (see captured text below). We certainly are lucky as digital ops to have a variety of modes to choose from.

Ham Radio Deluxe/Digital Master 780 would have the 250/2 as well as many other mode as well as even 125/2.

It should be better, because of the Walsh code layer. I have used it for tests among other Olivia modes, but never compared RTTY and 2/250 Olivia. It worked fairly well, but it was just for curiosity sake, more than anything else. It was not a serious, well planned, exhaustive test. 73, Jose, CO2JA Sholto Fisher wrote: Has anyone ever experimented with the 2 tone Olivia submodes?

Re: [digitalradio] OLIVIA 14074
Ciao Claudio, Funziono molto spesso Olivia e qui sono i modi che normali di funzionamento ho trovato per le frequenze differenti: Fra 14072 e 14078 (USB), ho regolato solitamente la manopola 1407x.65 (14072.65, 14073.65, ecc), il programma di Olivia a 500/16 e la frequenza concenta audio (ACF) o ha sfalsato a 750hz per denominare o rispondere ad una CQ. Ciò è la maggior parte del modo del comon ed è che cosa troverete suggerito sul Web site di HFLink. A volte troverete un QSO che è stato commutato a 250/8 per il tasso più veloce di parola-per-minuto ma che non è normale per la chiamata della CQ. Fra 14101 e 14109, ho regolato solitamente la manopola 1410x.50 (14104.50, 14105.5, ecc), il software di Olivia a 1000/32 ed il ACF a 1000hz per la chiamata o la risposta della CQ. Una volta che un QSO è stabilito ed il collegamento è buono, potete commutare a 1000/16 per velocità più veloce della trasmissione. Inoltre, parecchia gente sta sperimentando con gli accoppiamenti di tono di 2000/128 e di 2000/256 (1500hz ACF) per il segnale molto debole Olivia. Parecchi contatti di distanza lunga sono stati stabiliti su 20m dopo de quando che chiusa e nessun altro segnale potrebbe ottenere attraverso usando il Web site del riflettore di K3UK Digital (www.obriensweb.com/drsked/drsked.php) per stabilire la frequenza e per avvisare altri alla CQ. Ciao, Arturo KD4ULB === Ciao Claudio, I operate Olivia very often and here are the normal operating modes I have found for different frequencies: Between 14072 and 14078 (USB), I usually set the dial to 1407x.65 (14072.65, 14073.65, etc), the Olivia program to 500/16 and the Audio Center Frequency (ACF) or offset to 750hz to call or answer a CQ . This is the most comon mode and is what you will find suggested on the HFLink website. Sometimes you will find a QSO that has been switched to 250/8 for the faster word-per-minute rate but that is not normal for calling CQ. Between 14101 and 14109, I usually set the dial to 1410x.50 (14104.50, 14105.5, etc), the Olivia software to 1000/32 and the ACF to 1000hz for calling or answering CQ. Once a QSO is established and the connection is good, you can switch to 1000/16 for faster transmission speed.

Rick, I have had amazing results on 80M with Olivia 500/16. With QRN crashes to 10 over nine, I was got near perfect print from a station in Florida that normally would run at S 7. True, the speed is a bit slow but a greater speed is provided with Contestia which I have used but have not yet tried under high QRN. I see no reason that Contestia 500/16 would not perform as well.

[digitalradio] Olivia 250/8
I just had a nice QSO with Bo W8ISG today. We first linked on standard ALE but the propagation was rapidly decaying. Before we lost contact on ALE, I sent a simple ALE AMD text message GO TO OLIVIA. We changed to Olivia 1000/32 and made good contact, but eventually, that dropped to about 75% print when the QSB made the signal impossible to hear. We then changed to Olivia 250/8. All of a sudden we had better than 90% print, and continued with a very nice (but slow) QSO... texting for a long time, without being able to hear each other. That's the first experience I've had comparing Olivia 250/8 with 1000/32 on 20 meters in near-threshold conditions. I am very impressed with 250/8 performance. Bonnie KQ6XA
Re: [digitalradio] OLIVIA Re: Best mode for severe QRN?
I like to use the narrowest possible bandwidth mode possible, but sometimes conditions are so bad, and there are unlikely to be many other stations that going to a wide bandwidth 1000 or even 2000 Hz mode I think it can be justified. So far, the consensus seems to be that Olivia will beat all other digital modes assuming you don't consider the bandwidth. While I consider 1000/32 Olivia, with its ~24 wpm to be too slow for practical keyboard use, I can see where it is better than not getting anything through at all. Olivia 500/16, at under 20 wpm, is even slower than 1000/32 and 500/8 is just under 30 wpm so while relatively slow, it is a little faster than the other two mentioned modes. The first two use 31.25 baud vs. the 62.5 baud for the 500/8 which may be pushing the limit for multipath. It would have been interesting if we could have gotten one of the Olivia modes to work better than CW which was extremely difficult and I was not able to copy much better than 70% or so. When conditions deteriorate like they did, it was not possible to communicate what alternative mode to switch over to. But, again, the problems that we are up against on the lower bands during warm weather are primarily the unrelenting QRN static crashes that blend into a continuous roar with a few spikes even higher than that. Except for a very few SSB stations, running full power, you don't hear that much on the lower bands with these conditions, without specialized antennas to improve S/N ratios, (beverage, flag, pennants, etc.) It is a lot to expect any non-ARQ mode to handle this kind of environment since even if you have signals usually above the lowest S/N ratio of AWGN for that mode, since the QRN is not AWGN and the spikes will often cause hits that I doubt can be repaired by any of the modes, and that includes modes that spread out and make the data redundant. There is a limit to how much QRN is too much, and I think that I have already found that limit. We will have to try some of the Olivia modes again, even though they are slower when compared to DEX and MFSK. From previous tests I recall that MFSK typically outperformed Olivia but maybe my memory is faulty? I do like the more forgiving tuning accuracy with Olivia. The other station likes Hell modes, although I do not really care for this mode either, and it is also very slow at 25 wpm, but maybe we would be able to decode better than the machine? I would like to hear of other experiences for those who have tested the various modes and found what worked best for them under extreme QRN conditions. 73, Rick, KV9U expeditionradio wrote: 1000/32 would blow all the QRN away, methinks John VE5MU Hi John, Yes, I agree, Olivia 1000/32 is excellent, it decodes at -13dB SNR.

[digitalradio] Olivia
Okay, I have downloaded and installed MultiPSK and am ready to try this new mode out. What are the best frequencies and times to listen for Olivia signals? Also, I understand there are variations in the mode - what do I operate and where?
Re: [digitalradio] Olivia dying?
After several years, the main digital mode still appears to be PSK31, especially on the higher bands. When a new mode comes out, some of us will test it and if it doesn't have some superior feature, may not use it that much. A good example is MT-63 which seemed fairly popular when it first came out, but has not been used that much as of late. Although Olivia is robust under some conditions, this is usually in the wider modes. The AWGN sensitivity is comparable to PSK31 but on bands close to the MUF, it may not be needed for casual QSO's. The fastest common speed is just under 40 wpm at the 16 tone/1000 Hz bandwidth, which is close to PSK31 but most other tone/BW's are much slower, typically under 30 wpm and even under 20 wpm in some cases. The 4/500 speed gets the the baud rate up to 125 which may be a bit too fast for many HF conditions. The mode that currently seems quite good to me is DominoEX, particularly with FEC. Even with moderate static crashes on my last Tuesday's test schedule, it would print solidly when I know other modes would have had problems. It may not perform so well when we try it during the more severe conditions on the lower bands during the summer, but it will be interesting to see. DEX has considerable tuning tolerance unlike MFSK16 which formerly was my favorite mode. MT-63 was exceptionally bad the other night under that condition of NVIS+ground wave (35 miles) with moderate power and modest antennas on 160 meters. ALE is so very wide, that I am not able to use it this afternoon due to the RTTY contest. At times there are three stations on RTTY in the 2000 Hz bandwidth of the mode. This does rather limit its use at times. I think we would all be interested in hearing of the experiences of other digital hams and how they rate the old and new modes. 73, Rick, KV9U Andrew O'Brien wrote: I received a Skype call from a ham asking me the very same question I was thinking last week...what has happened to Olivia?

For me, it is ABSOLUTELY THE BEST, but that it has not caught mass attention does not mean it is dying. It is just another screwdriver in the drawer. It is slow, but if it gives PERFECT print more than 90% of the times MFSK has a pro and a con. It is HARD to tune, but it may transmit small images. When Hell is unreadable, Olivia still gives perfect print. And for me, DEX is not half as good as Olivia to cut thru. And Olivia gets thru when 141A does not.

Re: [digitalradio] Olivia dying?
Patrick, My understanding is that the modulation for the image is not related to MFSK at all, so any digimode program that includes the MFSK image routines would work. The initiation is text, for which the reliability is required. The width is about the same as MFSK so it would not work with narrower modes, but with equal or wider it should. 73, Leigh/WA5ZNU On Sat, 24 Feb 2007 2:57 pm, Patrick Lindecker wrote: Leight, Technically, you are right.

Yes, but in the program it's mixed (it was difficult to completly separate MFSK and SSTV in MFSK) The width is about the same as MFSK so it would not work with narrower modes, but with equal or wider it should. Yes, and with wider modes as Olivia 1000x32, the choice would be either to have a better quality image or a quicker image. But it would more fun to instead send an analogical SSTV image to send a very strongly compressed digital SSTV. 73 Patrick - Original Message - From: Leigh L Klotz, Jr. To: digitalradio@yahoogroups.com Sent: Sunday, February 25, 2007 12:21 AM Subject: Re: [digitalradio] Olivia dying?

RE: [digitalradio] Olivia 500 Re: Best Mode for QRP?
We have lots of comparisons of modes, but we don't but them side by side...how about a comparison list like this... mode -|- thruhput in WPM -|- %error free -|- robustness (%error free at what SNR) -|- Bandwidth You might have to qualify this by using certain power levels and receiver sensitivity. This would answer lots of questions concerning which mode was best.

[digitalradio] Olivia Dx contact just now GG76Bt to KN95KA
Wonderfull! After more than a year off radio, just scanning the 21MHz band, and amazed on seeing and hearing a strange signal at this hour on this band, by trial and error I was able to have a good and very well readable QSO with Arkady, RN6A locator KN95KA at 17:48 UTC. I was just trying to get familiar with all the nice options in MIxW v. 2.16 and never before had the opportunyty to test this Olivia mode.

[digitalradio] Olivia Re: An experiment: CQ test
Hi Jerry, Olivia 500/8 is not used as much for CQ as Olivia 500/16 and Olivia 1000/32 are. When using Olivia it helps to be exactly on one of the calling or working frequencies, otherwise your signal may blend into the background.

Re: [digitalradio] Olivia Digital Magic Mode for QRP and DX
I think we need to get away from the idea that different modes can not coexist (within reason). Consider that many are promoting a change by the FCC to base the occupancy by bandwidth, rather than mode. At the very least, you would expect the digital ops to be able to do this. Typically, I have operated all my non-PSK31 digital modes in the areas just above the PSK31 watering holes. So for 20 meters, that would be around 14073 and up. One thing to keep in mind is that if we do move toward the requirement of BW limitations, the digital modes will be affected if the wider ones have to move up a considerable distance from where they can now operate. At this time, one can operate with variable BW modes (e.g., Olivia), and change BW if conditions warrant such a need. That will not be possible if the legal BW is narrower in that part of the band, than the mode is wide. But for right now is entirely appropriate to operate such modes in the CW/Digital area. At least where I live, there are often no signals at all in the area just above 14070 to perhaps 14095. In terms of the First Amendment, I know where you are coming from on this, but the First Amendment here in the U.S. only pertains to what government can NOT do to the citizens. Not what the citizens can privately do to each other. (Not that I approve of what goes on with some moderation on some groups). This evening I was calling CQ on 160 on PSK31 but no luck. I happened to look at the W6RK site and noticed some activity on 20 meters so moved up there and heard K3UK calling on what I believe was CHIP 64. The signals were a bit weak and it is not always easy to see the waterfall characters that were being used to annunciate the mode, but it looked like CHIP anyway. So I called back and no luck. So then I heard AC7HA calling CQ on Olivia 500/8 just a short distance away and called him and no luck:( So I then called a couple of CQ's on Olivia 500/8 myself and a station came back. I figured it had t be AC7HA but it was WA3QHJ. His signals were just at the noise level on the ICOM 756 Pro 2 here (no preamp) and I was able to print him. We did pretty well for a number of exchanges and I kicked in both level preamps which helped. We eventually did loose each other as signals went to zero. I was still able to print him quite well even with almost no audible tones and and a barely perceptible waterfall. But when you basically have zero signal, there does come that time of no printing at all and that finally did happen. So then I happened to check the W6RK site and noticed some Hell mode on 20 meters and went up there and had a Q with AD6FR, but we did it below the PSK31 watering hole around 14064 actual frequency. 73, Rick, KV9U Thomas Giella KN4LF wrote: There is a second Olivia Yahoo eGroup at http://groups.yahoo.com/group/olivia_mfsk .There is no heavy handed moderator control in this eGroup, as the 1st amendment is respected.

Re: [digitalradio] Olivia 500/8 Center-of-Activity 14076kHz-14079kHz proposed
Bonnie, From my frequent monitoring, I would have to say that the only really popular mode is PSK31. It is not uncommon now to have more PSK31 signals within a 2.3 KHz passband, than even cw signals during a contest. Like this weekend you might find 4 to 6 cw signals but you would find up to 12 PSK31 signals in the watering hole on 20 meters. From time to time there are other digital modes being used, of course, and Olivia seems to be the third most common, (after RTTY keyboarding), even though no where near the concentration of PSK31. What I would like to see are some practical bandplans that have a recommended spot frequency for digital modes. We do have that by default now on 20 meters for the .070 PSK31, and similar areas on 40 and 80 meters. The RTTY operation is often about 10 KHz higher as you point out. But except for contesting, RTTY is not as popular anymore as other digital modes and probably will drop off even more as older hams become SK. No one has any particular claim to any part of any band, other than being able to work in the regulated areas for digital or for those who follow bandplans, within the bandplan recommendation. If you go to the ARRL site and look at their bandplan recommendations, one realizes that they do not distinguish between digital modes except for the automatic subband area that they call packet. Everything else is called RTTY. If we had a spot frequency that was recommended for newer modes that have not had a de facto watering hole, like PSK31, then we could start from there and if the frequency was busy, move up to the next available slot. As it stands right now, there can be Olivia, or Domino, or MFSK16, etc. over fairly wide areas and it is very easy to miss a call. Since there are not that many stations that work these modes, it would reduce the number of times that calls are made with no response. Another consideration is the dearth of digital operation (except for Pactor e-mail) on 30 meters. I have called many times on this band and had no luck with other stations being around. If you have to make a sked via the internet to even work a mode on a given band, that doesn't say much about that mode:( But when I compared the recommendations between say Region 1 and 2, they don't even agree on where data modes should be operating on 30 meters. Region 1 is 10.140 and up and Region 2 is 10.130 to 10.140 if I read it correctly. Maybe it would be wise to have a domestic starting frequency and a DX starting frequency? For example, I have often moved just above the commercial RTTY station near 10.130 and called. Maybe I should move up to 10.140 dial frequency and then try 10.141 or 10.141.5? In the final analysis, there are way too many new different digital modes, used very infrequently, to have special subbands, but they could have a recommended starting frequency for calling. Otherwise my rule of thumb is to see where the last PSK31 station is operating and go just above that and start calling with whatever mode de jour I happen to be using at that time.
