[digitalradio] MFTTY On Air Sensitivity
All, Had another opportunity to test MFTTY on air today. As expected, sensitivity goes hand-in-hand with character speed and the slower 1/8 mode is probably close to what you might expect from say PSK31. Path simulations seem to indicate that the mode is probably more stable than PSK31 when HF path distortion becomes an issue. I'd appreciate any thoughts / experiences with MFTTY performance; slow vs. fast mode etc. Tony - K2MO

Re: [digitalradio] MFTTY Path Simulaitons
Steinar, I did test the FEC mode at half speed using the "canned" simulations from Moe Wheatley's PathSim and there doesn't appear to be any difference in performance. The half-speed mode seems to be quite a bit less sensitive than other keyboard modes and I would imagine throughput would suffer when signals are weak. The 1/4 and 1/8 speed modes have better sensitivity, but they are slow. It does appear to have better stability than say PSK31 when signals are severely distorted; at least that seems to be the case with polar path simulations (see below).

Re: [digitalradio] MFTTY - HF Path Simulations
Skip, Glad to hear that the path simulations coincide with your on-air tests. I agree with your take on Olivia 500/16 and MFSK16. There are times when I'd rather sacrifice some throughput and go twice as fast. The throughput gap between the two does increase under severe ionospheric distortion as you can see in the high latitude tests below. We'll have to wait for another ionospheric storm and work over the pole to confirm what the simulator indicates. Thanks Skip...

Re: [digitalradio] MFTTY - HF Path Simulations
Selective Fading SNR -8db >> MFSK1690% >> Olivia 500/15 100% >> PSK31 65% >> RTTY 45 25% Although MFSK16 produced 10% errors when Olivia produced no errors, Olivia 16-500 (20 wpm) takes twice as long to send the same information as MFSK16 (42 wpm), so it is exposed to QRM and QSB over a much longer time. If you are only interested in exchanging name, qth, and signal report, Olivia will usually do that better than MFSK16, but for ragchewing, over a longer time period, using IMHO MFSK16 will probably be as good as Olivia without having to wait as long for the text to appear. 73, Skip KH6TY
Re: [digitalradio] MFTTY - HF Path Simulations
Thanks for the tests, Tony. The numbers confirm what NC5O and I found yesterday with our on-the-air comparisons between MFTTY, PSK31, PSK63, PSK125, and MFSK16 over a period of four hours and changing band conditions. We could communicate on PSK31 long after MFTTY had quit decoding, and solid copy using MFSK16 (but with a wider bandwidth, of course) when PSK31 started producing errors. 73, Skip KH6TY - Original Message - From: "Tony" To: Sent: Saturday, January 17, 2009 3:59 AM Subject: [digitalradio] MFTTY - HF Path Simulations > All, > > I was able to take some time to test MFTTY with the HF path simulator this > evening.

[digitalradio] MFTTY - HF Path Simulations
All, I was able to take some time to test MFTTY with the HF path simulator this evening. I added a few commonly use modes for comparison. As expected, the slower / narrow MFTTY modes seemed to have a definite weak signal advantage over the faster ones. The minimum SNR test showed a wide 12db gap in sensitivity between 1/8 speed and double speed modes. This should show when testing the different MFTTY modes on the air. In the HF simulator tests, each mode was subjected to same HF path distortion. The less tolerable a mode is to this distortion, the greater the throughput errors. It would seem that MFTTY would compare well with other more robust modes if the character speed is kept down using the half and quarter speed modes. At least that's what the HF simulator seemed to indicate. I'd appreciate hearing about on-air tests from you all so I can compare some real data to the simulators.

Yes I have been deleteing the program before I install the new one.

No problem, Steinar. I'm just working my way along my learning curve here. I just noticed that I get the Pilot tones when I have the "Send Immediately" box checked. Then, when I select the Pilot CQ, the tones are sent at the beginning of each line as typed in the box. If i select "Send By Enter Key" or if I UNCHECK BOTH selections, the "SEND" button appears and in any case, NO Pilot tones are sent. They're sent ONLY when the "Send Immediately" box is checked. I should think that the tones should be sent anytime the CQ is sent or perhaps when text otherwise is being sent and I insert somewhere inside any typed text. However, that isn't the case. The only time the tone is sent is at the beginning of a line where I place . It cannot be inserted anywhere else, so that seems to make it difficult to increase the number of Pilot tones as recommended in the information I read. Unless, of course, the Pilot tones are only used during a CQ sequence, then all of this is moot. The only issue then is being able to transmit tones in instances involving using "SEND" button or "Send By Enter Key" which doesn't happen now.

Hey, Steiner I have it installed. Before I did anything else, I modified the Pilot CQ to add my callsign and Grid Locator (EM79). When I selected the Pilot CQ (I'm using the "SEND" button now) I found four tone "beeps" transmissions being transmitted.

dear steinar you can switch it on your own to 1500 but you have to dial your trx 500 hz lower to be on the same frequency when somebody in the group sends a mail like :qrv in mftty on 14.075 or something like this the best way is when somebody wants to make a sked he should ad af frequency in the announcement like qrv in mftty on 14.075 + 1500hz mode 1/4speed so others will find the station easier good luck with this new mode best 73´s de dg9bfc sigi - Original Message - From: Steinar Aanesland To: digitalradio@yahoogroups.com Sent: Sunday, January 11, 2009 12:34 PM Subject: Re: [digitalradio] MFTTY Tuning information Hi Norbert Thanks for giving us this very interesting and easy to use software.

Re: [digitalradio] MFTTY: It works
Rick, You are correct regarding bandwidth, there was several discussions awhile back regarding the 30 meter band where some argued that we were restricted to 500Hz, I didn't subscribe to this and I thought 1Khz was acceptable. Anyway my thoughts are based on what space is available so as not to cause QRM to other users on the band, what I see from the MFTTY widths when selecting a mode is anywhere from narrow (29Hz) to (986Hz) plus a S/N ratio of -27 to 8db. The normal mode (speed) provides 75wpm at 936Hz (bw) and a 0db SNR were as the 1/2 speed provides a 38wpm at 468Hz (bw) and a -3db SNR. Frankly I believe that Olivia and Thor will accomplish the needs of digital operators better. Thanks for your input I learn something every day.

Re: [digitalradio] MFTTY: It works
Ron, Although I am not strongly supportive of wide bandwidth modes in what has historically been the narrower portions of the HF bands, I will use 1000 or even 2000 Hz modes under conditions where a given band is almost devoid of signals, or under severe conditions. This is not a criticism, but where do you find any reference to an "allowed bandwidth?" There are no specific HF digital frequencies that I am aware of here in the U.S.It is true that on the HF bands we have RTTY/Data portions and phone/image portions. Digital modes can be used throughout the bands based upon the type of information to be transmitted. (The third symbol in the ITU Classifications of Emissions). The one change in the past few years was allowing image (fax), whether digital or analog, in the RTTY/Data portions of the HF bands, providing the emission is 500 Hz or narrower. But non-phone emissions have no specific bandwidth limit except that they may not "exceed the bandwidth of a communications quality phone emission of the same modulation type." There is a special restriction for stations in automatic operation where there can be a 500 Hz limitation. But there is no such limitation with operators communicating from their control points. Finally, there are band plans from various groups, particularly the IARU and while they appear at times to not properly reflect current actual operating practices, they can be used as a guide. 73, Rick, KV9U w4lde wrote: > Russell, > > Thanks for the #1 MFTTY QSO on 30 meters.

Re: [digitalradio] MFTTY: It works
Russell, Thanks for the #1 MFTTY QSO on 30 meters. I would suggest that since the stated Bandwidth for 1/2 speed is 468Hz that probably that keeps us inside the 500Hz allowed bandwidth for most of the digital frequencies. What I see interesting is the RX bandwidth at hald speed which is 15Hz. That helps explain why so many are having trouble syncing in on a station. I think that the mode needs lots of work before it can be used by all. I can't get the help file to open.
