Guidelines for the Olivia MFSK Digital Mode (on HF)
Our Olivia group's web resources are available to all members. Our Messages are archived and available to all members, as is our Wiki pages (which are still under development). All of these resources are viewable and searchable by members. Our message archive is indexed by major search engines. Unfortunately, due to Groups.io restrictions, you must be at least a basic member of Groups.io -- with a validated login -- as well as a member of this Olivia MFSK Digital Mode on HF group, and logged in, to access our Files and Photos sections.
We expect members to post and act responsibly. Please respect your fellow members' time and attention: strive to be clear, concise and courteous. Our subject matter naturally includes matters of opinion; if you happen to disagree with another member please do so without being rude. Personal attacks are not allowed. Solicitations are off topic and will be deleted without comment. Listing your groups in your signature is perfectly acceptable, but just make sure there's also on-topic content in your post.
Attachments are allowed and the judicious use of screen shots and other illustrations is encouraged!
All messages sent to the members of the Olivia group are moderated. This is done to avoid malicious attachments, spam, off-topic messages, and messages from spoofed or compromised mail accounts. Despite these measures, be aware that the bad guys are clever so there's no guarantee that we'll always succeed; you are encouraged to be vigilant against any and all threats arriving via email. Your Olivia group moderators make no guarantees regarding the safety of emails arriving from this or any other Groups.io address.
We are always looking for suggestions from our members to make this group better for all. Feel free to address any questions, comments, or concerns directly to the group moderators via email to Oliviaemail@example.com
The Olivia MFSK Digital Mode on HF Group's Mission Statement
We strive to be a resource of the highest quality for individual amateur radio operators (and SWLers) interested in the Olivia digital mode on HF. To this end, we allow as much information as possible from our group to be accessed by visitors!
We thank you for your interest and for your contributions. See you on the bands, in my Olivia waterfall!

Additional Group Details
This group requires topics to be tagged with a hashtag.
These are the currently available hashtags for your use:
#Channelization => #OliviaChannels
You can see the description for each of the above mentioned tags by going to the Hashtags page. On that page you will find each hashtag, and colors associated with them. There's also a count as to how many email messages include that tag.
If you want to post something and are not sure which hashtag to use or there isn't an appropriate hashtag, use #misc. I will consider adding a new hashtag. Please try to use the existing hashtags whenever possible, as I will be limiting the total number of hashtags. #meta is the tag to use when making suggestions about this group. This group is set so that all new topics are moderated. Therefore, expect a delay before your post shows up if it creates a new topic.
PROPOSED NEW CALLING FREQUENCIES FOR OLIVIA
The following is proposed, and I will publish soon, upon general public acceptance.
Timestamp: 16:50 UTC, 30 June 2020
OUR CURRENT (2020 - MAY) SUGGESTED OLIVIA CALLING AND LISTENING FREQUENCIES
These are suggested frequencies on which can be found WEAK (i.e., a signal that you cannot hear, a signal not seen on the waterfall) Olivia signals. While it is easy to spot a STRONG Olivia signal anywhere on the waterfall, by using these suggested calling frequencies at least once and awhile, you will enable us to find your signal when the signal is too weak to hear and too faint to see on the waterfall.
Olivia can do well with weak signals. Yes, our suggested 8 tone with 250 Hz bandwidth results in slow transmissions. But, it is one of the better settings when attempting to decode very weak signals.
Once you make contact, you ought to move up or down a bit, but only on clear frequencies, away from the original (calling) frequency. By moving, you are freeing up the calling frequency for others to hunt for exotic signals through the same window. After you move off of the calling frequency, change to a standard configuration, such as 16/500 to make the conversation go faster. (That is 16 tones, in a 500-Hz bandwidth).
But, on a calling frequency, it is advisable to configure operations in such a way as to increase the likelihood that you will find and decode that weak signal.
In the following list, CENTER is where you place the center of the software's cursor, and click to select that center frequency on the waterfall. If you use the DIAL frequency from this list, then click 1500 Hz offset up the waterfall (1500 Hz to the RIGHT of the LEFT side of the waterfall, if your waterfall is oriented horizontally with the lowest frequency on the left). This results in the software and transceiver being correctly tuned for the CENTER frequency.
The listing shows CENTER, then DIAL, then the number of tones and the bandwidth.
CENTER | DIAL Tones/Bandwidth (Notes) 1.8390 MHz | 1.8375 MHz 8/250 (ITU Region 1, etc.; Primary International) 1.8270 MHz | 1.8255 MHz 8/250 (ITU Region 2; Secondary) 3.5830 MHz | 3.5815 MHz 8/250 7.0405 MHz | 7.0390 MHz 8/250 (ITU Region 2, etc., Primary International) 7.0730 MHz | 7.0715 MHz 8/250 (Secondary) 10.1430 MHz | 10.1415 MHz 8/250 14.0730 MHz | 14.0715 MHz 8/250 14.1075 MHz | 14.1060 MHz 32/1000 18.1030 MHz | 18.1015 MHz 8/250 21.0730 MHz | 21.0715 MHz 8/250 24.9230 MHz | 24.9215 MHz 8/250 28.1230 MHz | 28.1215 MHz 8/250 REMEMBER THAT IF YOU USE THE DIAL FREQUENCY (THE SECOND FREQUENCY IN EACH ROW, ABOVE), SET YOUR WATERFALL CENTER AT 1500 Hz
If your software is able to decode/encode the Reed-Solomon Identification signals (RSID), please turn on both received and transmit RSID. An example is shown in the following video, which demonstrates enabling RSID in a popular software suite: https://www.youtube.com/watch?v=lBIacwD9nNM
Please share this everywhere possible, as part of our effort to rekindle the love for our conversational mode, Olivia.
Please read and occasionally refer back to the announcement posts that are pinned in the group. Link: https://www.facebook.com/groups/olivia.hf/permalink/2376156415811086/
Please feel free to post when you or others are active on-air using Olivia. Be sure to list CALL SIGN, CENTER FREQUENCY, CONFIGURATION (i.e., 8/500), UTC start time, etc.
Be kind, courteous, patient.
Stay on topic!
If you post something in this group, expect that people will respond. That's how it works. Some people might disagree with you. Get over it. What is a discussion if everyone already agrees with you? Healthy debate includes disagreement. That's how conversations work. If you get your underpants in a ruffle, don't risk posting. But, I challenge you: Stick around and try allowing people to discuss things even if in disagreement. Something good might result. We make our hobby better, by discussing things. Just keep it civil. Okay?
Our goal is to provide a friendly environment to explore, ask questions (perhaps answer a few), and enjoy stories & experiences with others in our hobby.
This group is about amateur radio. We are not limiting membership to just licensed amateur radio operators. However, the focus is on amateur radio, primarily.
