PROPOSED NEW CALLING FREQUENCIES FOR OLIVIA The following is proposed, and I will publish next weekend. Please comment. * start * *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 a while, 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 can move up or down a bit, away from the calling frequency, and then change to 16/500 to make the conversation go faster. 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 > 7.0400 MHz 7.0385 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, > 10.1440 MHz 10.1425 MHz 16/1000 (Potential - be mindful of other > stations) > 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 PER ROW), SET YOUR WATERFALL CENTER AT 1500 Hz) Join us on Facebook at https://www.Facebook.com/groups/olivia.hf Join us on Groups.io via http://OliviaDigitalMode.net ALSO: 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. 73 de Tomas, NW7US ( http://nw7us.us ) dit dit + https://QRZ.com/db/NW7US ( https://qrz.com/db/NW7US ) + Space weather and radio propagation ( http://SunSpotWatch.com ) editor for CQ Amateur Radio Magazine ( http://www.cq-amateur-radio.com/ ) , and The Spectrum Monitor ( http://www.thespectrummonitor.com/ ) magazine. + YouTube: https://YouTube.com/NW7US ( https://youtube.com/NW7US ) + Social Media: - Twitter: @NW7US ( https://Twitter.com/NW7US ) = https://Twitter.com/NW7US - Facebook (As NW7US): https://fb.me/NW7US - Facebook (As Space Weather and Radio Propagation Page): https://fb.me/spacewx.hfradio - Blog: https://blog.nw7us.us ..
