[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).

[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.

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 d...@optonline.net To: digitalradio@yahoogroups.com 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.

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
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 error '380'
The reason for a version change IS because something has changed. There are many reasons under Visual Basic for getting a run-time error message, and perhaps your reload then overwrote the older values the program was still using, and that is why it is working now. Just my guess, not knowing the details of Norbert's code. It is usually best when upgrading to delete all previous code, such as a .ini file, etc, but I do not know what or where MFTTY is writing to the hard disk, so deleting all the previous files before upgrading is not possible, and we are left with having the program just overwrite them. 73, Skip KH6TY - Original Message - From: Russell Blair russell_blai...@yahoo.com To: Digital Radio digitalradio@yahoogroups.com Sent: Friday, January 16, 2009 8:43 AM Subject: [digitalradio] MFTTY error '380' I updated to the newer version 3.0.146, and I am getting a (run-time error'380' Invalid property value), this error didn't show up in any of the older version, I have to delete the program and reload it to get to run.

Re: [digitalradio] MFTTY 3.0.143 is out
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 Pilot somewhere inside any typed text. However, that isn't the case. The only time the Pilot tone is sent is at the beginning of a line where I place Pilot. 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 Pilot tones in instances involving using SEND button or Send By Enter Key which doesn't happen now.

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. Happy Holidays and a safe and wonderful 2009 to you and the family 73 de Ron W4LDE Rick W wrote: 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. 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.

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. O'well back to the standards 73 de Ron W4LDE Russell Blair wrote: Toby, set it to 1/2 speed and see if I can copy you hr in Texas Russell = *IN GOD WE TRUST !* = Russell Blair (NC5O) Skype-Russell.Blair Hell Field #300 DRCC #55 30m Dig-group #693 --- On *Sat, 12/13/08, Toby Burnett /ruff...@hebrides.net/* wrote: From: Toby Burnett ruff...@hebrides.net Subject: Re: [digitalradio] MFTTY: It works To: digitalradio@yahoogroups.com Date: Saturday, December 13, 2008, 1:13 PM Hi all, Just downloaded the MFTT software, I'm on the Isle of Lewis, NW Scotland.

Re: [digitalradio] MFTTY: It works Help file (Ron)
Ron, I download the help files to, but mine works in the program on top (?) and
it pulled the help in HTML format. Yes the program needs some more work for me

Hi all,
Just downloaded the MFTT software,
I'm on the Isle of Lewis, NW Scotland.
Listening 10.135,5
What speed etc should I be set too and I will
listen.

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.

you can just send text like in any other mode or you can control a local repeater via dtmf or you can use it for echolink so many possibilities for use of that software greetz dg9bfc - Original Message - From: Andy obrien To: digitalradio@yahoogroups.com Sent: Saturday, December 13, 2008 4:43 PM Subject: Re: [digitalradio] mftty So, in what ways are people using this on the air ?
