[digitalradio] TARA RTTY Mêlée - December 2, 200 6
Greeting's: It's time that we start gearing up for the next running of the TARA RTTY Mêlée which is coming up on December 2, 2006. We had a FANTASTIC response to our contest last year and I hope it will even be better this year. For those of you NEW to RTTY contesting this contest is the perfect warm up for the ever popular ARRL RTTY Roundup in January. For those of you that might be trying out some new antennas or software packages, I'm sure you'll find the Mêlée a perfect opportunity for you to ready your station for the many contests coming up this winter. Below, you'll find the info for the Mêlée. If you need any additional information I'd be more than glad to assist you. Simply drop me an e-mail at: (_mailto:[EMAIL PROTECTED] (mailto:[EMAIL PROTECTED]) ) TARA RTTY Mêlée--sponsored by the Troy Amateur Radio Assn, from Z-2400Z Dec 2. Categories: SOAB-HP (150 W), SOAB-LP (150 W), MOAB, SWL, Max 6 band change rule per clock hour for MO. Frequencies: 160-10 meters (Special Note: 160 Meters is now allowed!), operate 16 hours max. Exchange: RS + State/Province or serial number for DX. QSO points: 1 pt/QSO. Score: QSO points--S/P/C counted once only (US and VE only count as S/P). For more information: _www.n2ty.org/seasons/tara_melee_rules.html_ (http://www.n2ty.org/seasons/tara_melee_rules.html) . Submit Scores (not logs!) by Dec 31, 2006 via TARA's on-line score submission form at _www.n2ty.org/seasons/tara_melee_score.html_ (http://www.n2ty.org/seasons/tara_melee_score.html) . I ask for all you to please check out our web site for information on the TARA Tour'ney. In the TARA Tour'ney, the contestants are competing for the honor of emerging as the annual King or Queen of the digital modes. The scores to achieve this are an aggregate of all their individual Tour'ney credits derived from their scores from the four (4) TARA All Season Contests. By the way, the Mêlée is part of the Tour'ney program so check it out at: (_http://www.n2ty.org/seasons/tara_tourney.html_ (http://www.n2ty.org/seasons/tara_tourney.html) ) In addition TARA now sponsors our very own HF Digital Awards Program. The TARA-PX and the TARA-Grid. The TARA-PX is the only Digital Prefix Award available since the WPX is SSB and CW only. The TARA-PX Award is a full service award offering Mixed, RTTY and PSK certification for FREE! until January 2007. If you feel that you qualify for a non-listed digital mode, please request that we review your information. The full info can be found at: (_http://www.n2ty.org/seasons/tara_awards.html_ (http://www.n2ty.org/seasons/tara_awards.html) ) Again, I look forward to printing you real soon! 73 de NY2U Bill Eddy President of TARA (_mailto:[EMAIL PROTECTED] (mailto:[EMAIL PROTECTED]) )
Re: [digitalradio] Re: OFDM data is Emission Designator D1D
I should have said that the subcarriers must be orthogonal because Pactor-3 uses each subcarrier to send an independent stream of bits. In someone else's email they verified that the subcarriers are indeed orthogonal. 73, John KD6OZH - Original Message - From: Rick Karlquist To: digitalradio@yahoogroups.com Cc: digitalradio@yahoogroups.com Sent: Wednesday, November 22, 2006 19:49 UTC Subject: Re: [digitalradio] Re: OFDM data is Emission Designator D1D John B.

Re: [digitalradio] Re: OFDM data is Emission Designator D1D
You are still confused about the definition of orthogonal. Before Orthogonal Frequency Domain Multiplex (OFDM), there are (Non-orthogonal) Frequency Domain Multiplex (FDM). It too used each sub carrier to send an independent stream of bits. The sub carriers were NOT orthogonal. They didn't need to be because their sidebands did not overlap. OFDM squeezes more carriers into the same space by making the carriers and their modulation orthogonal to their next door neighbors. This allows some overlap. The subcarriers in Pactor-3 may indeed be orthogonal (I don't know) but that cannot be deduced from the fact that they carry independent streams of bits. Rick N6RK John B.
