Re: [digitalradio] PSK-ARQ versus ALE-400
> Rick wrote: > Wouldn't the variability be due to not knowing the conditions we operate > when on the air vs. the controlled and known conditions during the test? Yes, that's the problem Rick. It's difficult to mimic on-air conditions with a simulator and I doubt there's one capable of duplicating the variability of the real ionosphere. My gut feeling is that the mode prints closer to the noise floor than my pathsim sensitivity tests indicate. There's always some degree of ionospheric distortion on a real HF channel and seeing the mode print at what appeared to be a lower on-air signal-to-noise ratio vs. the simulators direct-path tests (no HF channel distortion) was impressive. This is all speculation on my part so we'll have to test some more. It probably won't prove anything, but it might be interesting to compare on-air recordings to the minimum signal-to-noise performance obtained from the simulator.

[digitalradio] CW - The other digital mode...
All, That "ancient" digital mode seems to increase in popularity each year despite what they say. It was a battle trying to find a clear 20 meter frequency to run in this weekends WPX CW contest. Was nice to see the 10 meter F2 opening to New Zealand (ZL1BYZ / ZL2IFB) and wished I had more than just a few hours of operating time to see what the bands were really doing. It's unusual 10 meter openings like this that make you wonder how often they go unnoticed. I'm sure the relentless band-probing by contesters made all the difference. So much for the lull in the cycle! Tony -K2MO
Re: [digitalradio] Re: QRV 14074.0 ALE-400 FAE
Ed, Sorry we didn't get a chance to work, but I'm sure we will in the days to come. I intend to put this mode through it's paces so I'll be on in the evenings for a while. So far, the mode seems to perform better on-air than during the path simulation tests. It's quite robust and has a pretty good balance between bw, sensitivity and throughput. It has a lot of potential as an ARQ chat mode. The semi-duplex - ARQ operation is certainly something all digi-ops should try. Thanks for all Patrick! Tony -K2MO

I'm very glad you brought this up to the group John. High latitude path distortion is one of the best examples of why we should use and appreciate the more robust modes more often; especially Olivia and it's derivatives. We all see the same instability on the majority of signals coming over the pole regardless of ones location (obviously more common in your case) and it's also quite common on low-latitude (spread-F) paths. Even a small amount of ionospheric "agitation" can cause throughput problems. Spread-F, multipath and other types of ionospheric instability can happen anywhere, anytime. This seems to confuse some PSK operators in that they can't understand why the print is so bad when signals are so strong. The phase meter is a good indicator of instability; the spokes in the meter tend to deviate wildly instead of staying straight and vertical. I recently had a QSO with JA1RZD on MFSK16 and I captured his QSO with another station just a few minutes later on PSK31. I think the text below speaks for itself. Path distortion was moderate, but was enough to cause problems with the narrow mode. I think PSK31 is a superb spectrum friendly, weak signal mode.

[digitalradio] ALE-400
All, Had a chance to see ALE-400 in action for the first time thanks to K7TMG. I was very pleased to see how sensitive the mode was and how well balanced it is between bandwidth and throughput. I did test ALE-400 with a path simulator a while back and sensitivity was very good. It seemed to be robust with moderate path distortion and showed partial decode with heavy distortion (see below). I'm not a fan of ALE because of the interference issues. But as an ARQ chat mode, ALE-400 seems to have little competition in the sound card class of modes. Those involved with digital ECOMM might want to take a hard look at this one. Patrick as done a terrific job with BBS, email, messaging and a bunch more Bells and Whistles.

Re: [digitalradio] [Fwd: Your comments on Polar Paths and Digital Modes]
Rick, Re: Polar Paths There's no doubt that the polar ionosphere can be brutal and it sounds like you had a 'double whammy" in your case where signal strength was an issue in addition to polar distortion. The RSID may have been useful in this case providing Ken was using it at the time. You might have been able to "force" his software to switch to an even more robust mode. Hey, if it was easy, we could all just get on Skype and talk to Ken ; ). It's the fascination with RF that seems to keep us going.

Simon, There does seem to be a slight improvement in PSK31 with lowercase. I put both upper / lower through the simulator with identical path parameters.

[digitalradio] More Path Simulations: Contestia / RTTYM and others
All,
Thought this might interest the group
The path simulation tests below show how each mode might behave under the same
signal-to-noise / HF path conditions.
Modes included in each test group have approximately the same word-per-minute
rate -- for example: Olivia 16/500, RTTYM 64/500 in test#2 all move along at
nearly the same rate.
The popular PSK31 mode was included in each test group for comparison.
Software - Fldigi Mixw PathSim.

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.

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.

[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

Andy, > With a slight improvement in the solar flux numbers and the longer periods of > sunlight > in the northern hemisphere, I wonder if we are at the point that 24 hour per > day will be > common using the robust weak signal digital modes? I think you have it right Andy. Ionospheric models show that the 20 meter band stays open much longer in summer than in winter, especially for locations within the northern hemisphere. A few paths come close to being open for 16 hours or more. The predictions also say that this happens regardless of where we are in the solar cycle and it all seems to correspond well with on-air experience. It seems logical since the summertime ionosphere is exposed to more direct sunlight for much longer periods of time. The polar ionosphere would seem to benefit most from summertime illumination. It seems possible that a slight variation in the 10.7cm solar flux could have some influence on propagation, but I would imagine it's much less significant compared to the seasonal changes. I've learned that it doesn't always go hand-in-hand with conditions and is often misleading... Quoting Robert Brown (NM7M) ... "the 10.7 cm. flux has its purpose, indicating the presence of active regions, and it is a mistake to think that changes in that flux are always associated directly with the state of our ionosphere." > I have been able to work Europe on low power with a vertical as early as 0800 > hrs, in the past > month Europe did not usually open until around 1200 UTC. That's a near perfect match to VOACAP's NY-EU predictions.

Open image file - click IMAGE then RESIZE / RESAMPLE. Images can be resized by setting the height and width or as a percentage of the original.

[digitalradio] Monthly Digital Mode Sprint?
All, I think we could benefit by borrowing an idea from the NAQCC. The North American QRP CW Club runs a two hour Sprint each month that seems to bring a fair share of ops out of the woodwork. New members are always being added so they must be doing something right. A digital mode Sprint should show similar results and putting the emphasis on multi-mode contacts for additional points would take care of the modes that sit dormant. There's also the camaraderie and the opportunity to sharpen skills on modes that are less familiar. Just a thought... See http://www.arm-tek.net/~yoel/index.html Tony -K2MO

Rick, > It is easy to determine the BW, but not so easy for the number of tones. The RSID would come in handy for this, but I don't feel it's difficult to determine the number of tones. The 500Hz mode seems to be the standard and it's rare to see anyone using more than 16 tones. Clicking through 8, 4 and 2 tones will usually find the correct combination quickly. > operators who have slower keyboarding skills have told me that they find that > the 19 or 29 > wpm of Olivia 500/16 and 500/8 to be a good fit. I agree - the 500/8 mode strikes a good balance between speed and throughput under most conditions. I asked Simon to include 500/8 as one of the point-n-click modes in DM780. > the faster Olivia modes may not work as well as other modes, particularly > MFSK16 which is > also much faster (~ 40 wpm) True - cutting the number of Olivia tones will cause a slight degrease in the robust quality of the mode in exchange for speed. But there are times when this will not effect throughput, i.e., moderate to good signal quality / stability. Re: Winmore I'm not so sure that this mode can compete with robust MFSK modes like Olivia.

[digitalradio] Olivia
All, I'm not sure why, but it seems that most of us tend to stick with the slower versions of Olivia even when conditions allow for much faster throughput. The more robust tone-bandwidth combinations seem overkill when the path is stable so why go slow? I sometimes test the waters by reducing the number of tones (regardless of bandwidth) to speed things up. One can always increase the tones again if conditions change for the worse. It would be a neat to see some kind of "throughput sensing" where the speed of the mode changed to suit conditions automatically. Maybe an RSID-like preamble that automatically switched the other stations software to the best mode based on the last over. Tony -K2MO

[digitalradio] Random Hour instead of MOTD
All, The mode-of-the-day may not be the best for what we want to achieve since it tends to put the emphasis on a single mode. A Random Hour on the other hand would promote the use of any mode starting at a specific time each day. With the help of RSID and video identification, operators can randomly select the keyboard mode of their choosing. The ID would be an essential part of random hour since it takes the guess work out of which mode is being used. It might be best to have both a local and universal start time. The meteor scatter group uses local time to promote their random hour efforts but they are dealing with a propagation mode that is limited to one or two time zones so it's not the same as HF. The time issue is open for suggestion. Fldigi and Multipsk have both the Reed Solomon and video ID. Simon Brown's DM-780 has video ID only, but that may change soon. MixW has video for MT63 only. Fldigi http://www.w1hkj.com/ HRD (DM780) http://www.ham-radio-deluxe.com/Downloads/tabid/54/Default.aspx Multipsk... http://f6cte.free.fr/index_anglais.htm So there you have it.

[digitalradio] Positive Feedback
All, Received lots of positive feedback this week about making use of some of the less-used digital modes so lets keep the enthusiasm going. Simon Brown mentioned the use of RSID to help with mode recognition. He may add this feature to DM-780 sometime in the future - thank you Simon. The ID is very sensitive and certainly takes the guess work out of trying to decipher which mode is being used. Both Fldigi and Multipsk have RSID. The mode-of-the-day idea will probably not put more modes on the air so we're still open for suggestion. Mode-specific contests might help, but ultimately we need to simply get on the air and call CQ more often. We are fortunate to have so many modes to use and I think we owe it to those who worked hard to bring them to us to use them. While we're on the soapbox... I think most would agree that we need more real conversation and less macro use regardless of which mode is being used. There's nothing wrong with a quick exchange, but a few words thrown in here and there makes the contact more interesting. Tony -K2MO

[digitalradio] Mode of the Day?
All, I'd like to propose a couple of ideas to the group to encourage the use of those digital modes that tend to sit idle much of the time. Seems to be a lot of unanswered CQ's these days so a little enthusiasm may go a long way. I was thinking along the lines of something simple to remember like the mode-of-the-day; an MFSK Monday or Olivia Tuesday for example. Both are excellent chat modes that see little use. The ability to send images with MFSK16 certainly makes it unique. A QRP day might encourage those with power / antenna restrictions to experiment with different modes modes to improve their success. The idea of a digital mode QRP calling frequency would help; certainly works wonders with CW QRP. Any thoughts? Tony -K2MO

[digitalradio] HF and the Spotless Sun
All, Interesting read about solar output and HF propagation by Paul Harden, NA5N. Tony -K2MO Paul wrote: During the quiet sun, solar flux in the 60-100 range is typical. During the active sun, 150-200 is typical. The higher the solar flux, the more ionizing radiation that is striking our ionosphere, producing free electrons that stratify into the D, E and F layers. The more free electrons in the E and F layers, the more reflective they are to HF frequencies and the higher the MUF. Right now, with solar flux in the 60-100 range, the E and F layers are poorly ionized, yielding a lower MUF and not acting as a very good mirror for bouncing HF signals back to earth. Very generally, when the solar flux is around 100, 15M will be open; above 150 10M will be open. Below 100, 20M will usually die shortly after sunset. IMPORTANT: The MUF seldoms drops below 10MHz. Therefore, the solar flux has very little effect on 30, 40 and 80M propagation. These bands are fairly immune from the solar flux and the 11-year solar cycle. Magnetic disturbances on the sun produce sunspots (cooler areas). Occassionally, the magnetic field lines of the disturbance(s) grow to such an intensity that it produces a small hole in the solar surface, allowing hot solar mass to escape. This is a SOLAR FLARE. While this hole is present (usually in the order of minutes to tens of minutes), energetic electrons and ionozing radiation (that is, x-rays and sometimes gamma rays) are allowed to escape. This, of course, quickly increases the overall radiation output of the sun. The ionozing radiation, when it strikes the earth 8 minutes later, will ionize the E and F layers, making them more reflective to HF and raise the MUF, usually for the rest of the day until local sundown. The radiation from especially strong flares can penetrate into our ionosphere to the D-layer. When the D-layer is highly ionized, it becomes very absorptive to HF signals, and in extreme cases, can produce a temporary HF blackout. Most flares will not appreciably increase the daily solar flux; therefore, the solar flux alone is not a good indicator following a flare to increased E and F layer reflectivity (and hence, good skip DX). As the number of sunspots increases, there is a higher chance of solar flares, and the daily solar flux tends to increase. However, there is *no* direct mathematical relationship between sunspot count and the solar flux. They follow the same trend when plotted, but no one can say 10 sun spots equals xxx solar flux units. The solar flux will vary from a minimum to maximum value over 28-days, related to the solar rotation. It also varies from minimum to maximum over the 11-year solar cycle. Thus, it is a slowly varying indicator that is used to show the general trend of the sun for the current 28-day cycle, and for the current solar cycle. It is not used for an hourly or daily predictor. Propagation programs use solar flux values primarily for calculating the MUF and what bands will be open, or closed, at different times of the day. When a solar flare occurs, it often produces a shockwave carrying electrons and other solar mass away from the sun. This is called a coronal mass ejection or CME. If the solar flare is located towards the center of the sun (as opposed to the limbs or edges), the trajectory of the shockwave will intercept with the earth, usually about 50-55 hours later. When this happens, the shockwave will compress the Earth's geomagnetic field, triggering a GEOMAGNETIC STORM, generating huge electric currents flowing along the Earth's magnetic field lines, causing increased noise levels. IMPORTANT: This effect is more pronounced on the lower frequencies, such that 30M, 40M, 80M are more effected by the "noise storm" than is 20, 15 and 10M. The amount of "wiggling" or disturbance to our magnetic field is the K-Index. It is measured every 3 hours to show what the present state of our geomagnetic field is. K=1 to 3 is fairly quiet to unsettled. Higher numbers (K>4) is a geomagnetic storm. K>7 is a severe to extreme storm. The K-Indices throughout the day are averaged over the UTC day to form the A-Index. It basically tells you what our geomagnetic field did YESTERDAY. It is usually expressed as the "Ap," or planetary A-index, being averaged over 24 hours and from all the reporting stations. THEREFORE, the SOLAR FLUX tells you the general radiation output of the sun. But, don't expect it to make a sudden jump to open up 15 or 10M. That takes years ... or an M or X-class solar flare. The A-Index tells you what our geomagnetic field did YESTERDAY. It tells you almost nothing about what the bands sound like TODAY. For that, find out what the current K-Index is. The lower the number, the better. Above about 6 or 7, conditions on the LOWER bands will be very rough. WHEN TO

[digitalradio] Polar Paths and Digital Modes
All, It's always interesting to see how different modes perform under adverse conditions. The polar ionosphere can be especially brutal on throughput and choosing the right mode can make all the difference. To illustrate this, I recorded a few QSO's I made this evening with JA1RZD, UA0QGG and RA0QW. All paths cut through the polar ionosphere from here in W2. The fluttery signals were easily recognizable by sight and sound. In a nutshell, JA1RZD's MFSK16 signal was near perfect copy. There was some obvious signal spreading that's typical on this path, but there were no garbled characters to speak of. That wasn't the case when I found him just a few minutes later working W9 on PSK31. Signal strength was the same but copy wasn't good. It would have been difficult to carry on a conversation as the text shows. I worked UA0QGG and RA0QW on PSK31 a few minutes later and the results were the same; difficult copy despite strong signals. A switch over to one of the MFSK modes would have improved things dramatically under those conditions. Low latitude paths (spread-F) show a similar kind of instability so this sort of thing is not just confined to the polar ionosphere. Thankfully, we have a number of modes that overcome this. BTW -- this is not to say that the PSK31 mode is no good; it is probably the best spectrum-friendly, user-friendly weak signal mode available and works just fine most of the time. It just goes to show that all modes can't do all things all the time. See text below... Tony -K2MO (JA1RZD on MFSK16) K2MO K2MO de JA1RZD JA1RZD Roger Tony. Tnx for the report.

Re: [digitalradio] Re: Contestia / MT63 Skeds pse
Rich, Had a good copy on you in MT63 and Contestia. It took a while to get MixW set up again and my temporary rig setup is unstable on transmit. You did have a strong signal to the Gulf Coast around 2330 until my crude wire lash up came undone. Just my luck... Thanks for trying om. Sorry to hear about the antenna problems and hope you get things going again. I'll be on this evening -- 14108.0 Thanks Rich... Tony -K2MO
[digitalradio] Contestia 16/1K vrs MT63-1K
All, Thanks to all who participated in the Contestia tests this evening. It certainly seems to have an advantage over MT63 in terms of sensitivity. Patrick Lindecker pointed out the mean-to-peak power ratio differences between the two and is no doubt the reason why Contestia is the more effective mode. Contestia does about 95 words-per-minute in the 16/1K configuration so it's somewhat slower than MT63. Turn around time is the same though since MT63 needs 12 seconds to flush the Tx buffer; Contestia has no latency to speak of. There was no QRM during the on-air tests so it's hard to say if it can resist interference as well as MT63. Being an MFSK mode, it will most likely tolerate multi-path and other ionospheric distortion well. In terms of high-speed chat modes, Contestia 16/1K is most likely one of the best configurations. More to come... Tony -K2MO

Re: [digitalradio] Contestia / MT63 Skeds pse
Patrick, Thanks for that information. Is it safe to say that the SNR difference between Contestia and Olivia stays the same as long as the tone and bandwidth configurations are the same? Can you also tell us what the approximate peak-to-average output is for MT63? I understand it's near 10db?

Re: [digitalradio] MT63 Operating Tips
Cortland, I would imagine the mode works well for passing MARS traffic. Contestia seems to have about the same wpm rate in the 8 tone / 1k configuration and throughput seems to be better. There's no latency either so it might be worth a try. Not much use for wide high-speed chat modes on the ham bands, especially since most of us can't type that fast ; ). They are fun to experiment with though.

[digitalradio] MT63 Operating Tips
All, Had several QSO's with first-time MT63 OPs this week. Some had a difficulty getting used to the software settings so I thought I'd pass along a few tips. Peak Power: Peak power will be substantially higher than the average with this mode so it's best to use the software's tune feature to set the transmitters output. The most common mistake is setting the RF output power with the MT63 signal itself. This can cause distortion / throughput issues. A typical peak setting of 25 watts will show about 5 watts average on your rigs meter. Software: Fldigi, MultiPSK and Mixw all work well. Nino Porcino's MT63 Terminal has signal report and tune features that are useful for the beginner. It also has a couple of nifty "analog" gauges that measure confidence and SNR. It works well and is easy to setup. Use the asterisk * in the transmit buffer to allow the type-ahead feature. See http://xoomer.virgilio.it/aporcino/MT63/index.htm Reception: Use the markers in the waterfall and keep the signal centered between them. Nino's MT63 software has a two-tone transmit marker that helps the other party tune your signal. It shows the receiving station where the top and bottom edge of the MT63 signal is. This feature is especially helpful when signals are weak. Fast Chat Mode: It will take some getting used to MT631K if your typing is slow; it's best to use the type-ahead buffer to keep things rolling along. The 1K mode does 100 wpm so text files can be sent at a fair pace. The cut-and-paste works well for sending emails and other small files. The mode resists QRM / QRN very well and will usually print with a fair chunk of the signal overlapped by another MT63 signal. Use common sense when running a wide mode like MT63. Listen carefully to make sure your not causing interference. The 1K, long interleave mode gives the best bang-for-the-buck. Tony -K2MO

Re: [digitalradio] THOR is static-proof (Re: KV9U - MT63)
Jaak, > What about THOR? Thor stated to be more static-proof. It depends which THOR mode is used. It seems THOR-22 is the best of the bunch for static crash resistance. I've done a few static crash tests by generating noise at regular intervals; the noise obliterates the signal in short bursts. I would imagine this method would give some indication of on-air performance. I'm sure there are simulators out there that can produce more accurate results. The list of variables that would add to the mix are endless; ionospheric distortion, weak / strong signal performance, QRM etc. As the disclaimers say, your mileage may vary! See below...

Rick, > You have done the tests and found that MT-63 is not very good at > handling weak signals compared with other modes. It is less sensitive than others, but some of the most sensitive modes are not necessarily the best performers when conditions deteriorate. I think it's reasonably sensitive though. > Is you recent on air testing to determine that or some other parameters, such > as > ability to handle interference, etc.? Not really. I pretty much know what to expect with MT63 because I've been using it since IZ8BLY first released it a long time ago. The most impressive thing about MT63 is how it seems to resist heavy static crashes. I made a few recordings with short segments of the signal removed to simulate this type of QRN and there was little effect on copy. It seems to withstand a lot more QRM than most and will usually print well with a good chunk of it's signal obliterated. There's a short video on this reflector in the file section showing how MT63 resists a combination of Pactor QRM and some fairly deep selective fading. > By the way copying both you near noise level, and Skip, KH6TY, a bit > stronger at S3-4.

[digitalradio] Weak signal tests - KH6TY / K2MO
All, Had an opportunity to do some weak signal testing with KH6TY. Signals were in the noise both ways and stayed consistent throughout the test. It was the perfect opportunity to test for sensitivity; ionospheric distortion aside. We tested Olivia 16/500, MFSK16, DomnioEX4 and DominoEX8 FEC. Although it is a bit slow wpm-wise, the Olivia mode seemed do very well. It would have been more of an apples-to-apples test to compare Olivia 4/500 to MFSK16 since they would have been somewhat closer in terms of wpm rate. There's always next time. See below...
