[digitalradio] Olivia Contestia path simulations
All, Interesting pathsim test: Contestia 16/500 and Olivia 4/500 move along at about the same wpm rate, but there's quite a bit of difference in performance. Contestia 16/500 THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG THE QUICK BROWN FOX JUMPS +UER THE LAZY DOG THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG Olivia 4/500 THE QUJv~BRO FO NMPS OVER THE LAZcvDOG T9\gQU`CK brjs_...@e#0xrer HE LAZY DOZ NSE QUiCK 4ReN FOX JUMPP3OVERfHE LAZ Contestia was virtually error-free at -10db SNR while Olivia did not do so well. The simulation was identical for both modes -- mid-latitude / disturbed. Olivia 4/500 did print error-free at -5db SNR so there's a difference of 5db between the two. Whether or not that actually shows on-air is another story. Tony -K2MO
[digitalradio] Contestia RTTYM
Is there anyone out there who uses both DM780 MixW who could record wave files using DM780 where the wave files contain Contestia and RTTYM trasmissions? You'll need to couple the programs using something like VAC. Ideally one file per mode with a reasonable long text. I need the waves files to be sure I implement Contestia and RTTYM correctly. I don't have mixW and don't use it less i get accussed of plagiarism and lawyers start hunting me (yes, it has happened before). Simon HB9DRV www.ham-radio-deluxe.com www.sdr-radio.com

Re: [digitalradio] Contestia RTTYM
Hi Simon and all I made some pathsimulations with RTTYM and Contestia from viewpoint QRP and contesting. My results show that both are dead modes. But RTTYM with UOS like Sholto believe it would be much better. The data about 1.5dB snr or 3dB in relation with original Olivia is myth. Better alternative is FEC-free DominoEX 5/11 for contesting and MFSK16 for everyday use. The original Olivia is bulletproof but a little slow and wide.

Re: [digitalradio] Contestia / RTTYM
This is where Patrick's RSID idea will help, I'm adding it to DM780 and maybe the MixW developer(s) could add it? Patrick - how does the RSID sensitivity / robustness compare to Olivia? Would there be any point in sending the RSID twice?

Re: [digitalradio] Contestia / RTTYM
Hello Simon, maybe the MixW developer(s) could add it? It would be good to include RS ID in Mixw, at least for the Mixw exotic modes (FSK31 for example). It could be indicated for the softs not decoding the exotic mode with which soft it could be decoded. For example, on reception on a (future) FSK31 RS ID (no RS ID for this mode at present), it could be indicated by Multipsk, DM780, FLdigi or Pocketdigi that FSK31 could be decoded by Mixw. This could also be interesting for softs (not being multimode) working on one particular or several exotic modes. Knowing the mode and the soft to use, it will permit more experimentation. My RS ID measures are the following: * the first RS ID decoding happens at S/N=-18 dB, * at S/N=-13 dB the RS ID decoding is almost systematic. Note: Tony measures a lower minimum S/N. According to the Olivia mode, the minimum S/N for these modes is from - 7 dB to -14 dB. Patrick - how does the RSID sensitivity / robustness compare to Olivia? So in general, RS ID is more sensitive than Olivia, Contestia or RTTYM. Would there be any point in sending the RSID twice? There are no limitations (in Multipsk, the RS ID macro can be sent several time). 73 Patrick - Original Message - From: Simon (HB9DRV) To: digitalradio@yahoogroups.com Sent: Thursday, May 21, 2009 9:30 PM Subject: Re: [digitalradio] Contestia / RTTYM This is where Patrick's RSID idea will help, I'm adding it to DM780 and maybe the MixW developer(s) could add it?

Re: [digitalradio] Contestia RTTYM
The data about 1.5dB snr or 3dB in relation with original Olivia is myth. My results show that both are dead modes I respectfully disagree Jaack. If you compare Contestia on a word-per-minute basis, you'll find it compares favorably with Olivia and in some cases will outperform it based on that criteria. For example: Contesita 16/500 and Olivia 4/500 have the same word-per-minute rate, but Contestia will have a 5db advantage over Olivia in terms of throughput on a moderately disturbed HF channel. Of course Olivia is left at a disadvantage because the number of tones were reduced to keep up with Contestia's wmp rate and I'm sure there's something to be said there. I'm sure the experts on this subject will shed more light on this, but I think it's only fair to include the wpm throughput when comparing modes of a similar type and bandwidth.

Re: [digitalradio] Contestia / RTTYM
Simon, As Patrick mentioned, the RSID is very sensitive. Multipsk was able to detect the ID down to -25db with the HF path simulator PathSim. It seems robust and decodes fine with moderate HF channel disturbances -- tends to fail under extreme conditions such as disturbed high / low latitude paths. At least that's what the simulator indicated.
