Patrick , Thanks for info. Still in the infancy stage of learning Ale 400 and MultiPsk. Any and all help is appreciated. Been printing the manual download for Ale.

Re: [digitalradio] ALE-400
Hi Tony and group members, Based on the use (or non use) of ARQ modes for general ham use, suggests to me that they are going to be primarily used for messaging. This is something that we must have for public service/emergency communications, but there are relatively few who are oriented toward digital modes (speaking from considerable experience). This is likely due in part to the use of VHF as the main part of the spectrum used for such activities. It is actually a very new concept in terms of these newer technologies (developed in past year or so) that work with weak signals rather than the older packet systems that required fairly good signals to work over modest distances. Even so, it is very difficult to get operators to even try the new technologies because the great majority are satisfied with only using VHF/UHF phone. Even the zero interface approach is a hard sell. Some of us on this group have used FAE400 on HF with success but three or four users is not enough, HI. Also, in order for new modes to become practical to use, they must be available on the programs that are being used. Based on comments from developers, it appears that FAE400 will only be available on Multipsk and this is more of an experimenters program rather than one used by public service or the average digital user. It may not be practical to build a team of operators, whether local or regional, etc., to use multiple programs where they use one program for e-mail, another one for packet, another for messaging, another for chat, etc. That is why I believe that we need one program that has this capability, and it would need to be simple to use, very basic layout that is understandable to the average ham. I believe that we are coming closer and some groups have standardized on certain programs. Even after we have the perfect program (until the next perfect one comes along), it will take an enormous amount of promotion to effect major changes, HI. One question for Tony: when you tested the ALE mode, was this actually the FAE mode? As I understand it, the FAE modes (wide 2000 Hz and narrow 400 Hz modes) are considerably faster than the older ALE modes due to improved compression, even though they use the same 8FSK modulation. And they are more sensitive, plus the memory ARQ feature of FAE adds additional weak signal capability. 73, Rick, KV9U Moderator, HFDEC (Hams for Disaster and Emergency Communications) yahoogroup Tony wrote: John, Hey man you are preaching to the choir!!!

Re: [digitalradio] ALE-400
And another point worth emphasizing is now that MultiPSK's RS ID detection can be extended throughout a 44KHz bandwidth using its SdR interface, it should be possible to initiate an ALE400 FAE ARQ connection to a friend using their SELCAL which will be detected by them automatically anywhere say in the entire 20m digital portion of the band if they have centered their SdR frequency to 14.091MHz (14.070-14.112 range). No need to scan on discrete frequencies, just monitor the whole digital band at once. To me, this has obvious EMCOMM possibilities. 73 Sholto K7TMG Tony wrote: All, Had a chance to see ALE-400 in action for the first time thanks to K7TMG.

Re: [digitalradio] ALE 400 auto speed change
Hello Rick, Do you think that it would be possible for some hams to develop something similar, or better yet, follow the MIL-STD specifications so that we have future continued interoperability? I think PCALE and MARSAle have also integered the 110A mode. I hope thay are interoperable with RFSM (?) for at least a common part. However as far as I know the 110A specifications just describe the way to send messages. It is not described: * the way to do the equalizer (everyone does the best possible) on the receiver part, * the protocol to work in an ARQ mode way. Do you have any idea why they use such a high baud rate all the time, even when sending the more robust slow speed data and use multiple repetitions? They use the same modulation: 2400 bauds 8ary PSK all the time, so to recognize any change of speed or interleaving length (given in the preamble). Of course you cannot have very good minimum S/N even at 75 bauds with such a high speed (minimum S/N must be =0 and depends on the bit rate selection), but reversely you can go up to a bit rate of 4800 bits/sec... I suppose that the implicite specifications are a very good throughput with a not too bad S/N. While the MIL-STD does provide for multi-tone as well as single tone, it appears that most development has been for the single tone, therefore there must be a logical reason for this. The single tone is the basic choice, multitones schemes are only options. I still don't comprehend why this concept is so good compared with multi-tone modems. In fact, some of the information I have been able to find, does have the multi-tone slower baud rate perform better than single tone high baud rate in some cases. But often it is supposedly very close. For the same mean HF power, I think the multi-tone must be better because the speed is low and you don't need an equalizer. The equalizer cannot have a perfect performance because the ionospheric transfer function can be identified only approximatively and the function is not strictly stationary between two known data transmissions. Is the reduced crest factor the main advantage for the single tone? Is it around 1.0? I don't see anything about some windowing in the 110A specifications so the crest factor is 1, when, for the multitone, it is very bad (around 0.1or 0.2 depending on the number of tones). What would happen if a slower baud rate were used with a single tone modem, instead of the high baud rate? (Of course it would not be MIL-STD anymore). The idea would be good but of course we will have an exchange between bit rate and minimum S/N qualities: the minimum S/N would be better and the bit rate smaller. But I think 2 tones would be also good: it would permit to double the bit rate, each tone being a channel for the convolutionnal coding. The crest factor factor would be 0.5 without windowing and around 0.35 with a windowing. If you would set your transceiver to the maximum (100 watts) you would supply 35 watts to the antenna, which is sufficient for a continuous working. HW? 73 Patrick - Original Message - From: Rick W.

Re: [digitalradio] ALE 400 auto speed change
With the ALE/FAE modes, the basic ALE 8FSK waveform is used, only slowed down in baud speed from 125 to 50, with the improved sensitivity but reduced throughput, but of course, a much narrower ham friendly bandwidth conserving mode when in ALE/FAE400 vs ALE/FAE 2000. Note that the bandwidth is perhaps five times wider for 2 1/2 times more throughput. This strikes me as one of the best features of Pactor 2 since it always stays close to a 500 Hz footprint, with a constant 100 baud rate, even when it moves to the higher speed constellations from DPSK and through QPSK, 8-PSK, and 16-PSK. Pactor 3 can expand and contract from over 2000 Hz down to around 1000 Hz when it drops to only 2 tones in its most robust mode. It only uses DPSK and QPSK and no higher constellations. At the slowest speed, it may only exceed P2 capability a modest amount (due to the wider spacing of the two tones), but has a net raw speed of only 77 bps. I would expect other modes to perform close to that with similar tone spacing. If you have larger set of tones, such as 8FSK, I wonder if you can adapt as much in terms of baud rate speed changes vs. keeping tone numbers smaller but with higher constellations? And then the bigger effect of P3 which can completely drop tones as needed for more robustness instead of speed. Dr. Rink (SCS) has said that PSK modes do require slightly less S/N ratio over FSK modes and perhaps with always on FEC coding may be a wise choice of modulation using two tones that are modulated with varying constellations? Most of the new soundcard modes have quite a few tones in them, at least 8 or more, and maybe reducing the number of tones might be more ham friendly and still have good throughput? Two tones effectively doubles the throughput compared with single tone PSK mode and yet allows for a relatively low crest factor in concentrating more energy into each of the tones rather than spreading them very thin across many tones. Pactor 3 is very similar to P2, but has the nearly five times wider footprint without being able to operate 5 times faster. I am not sure how often P2 can reach the highest speed level of around 700 bps plus compression compared to how often P3 can reach its highest speed level SL-6 at 2722 bps plus compression, but I suspect that P2 can generally outperform P3 when you take the bandwidth into consideration. But if we only need to change the baud rate of the 8FSK signal, we can do that now with switching between 8FSK50 and 8FSK125 with the attendant problem of drastically widening the footprint and the increased difficulty of finding a clear area to transmit. 73, Rick, KV9U So Andrew O'Brien wrote: Would it be possible for ALE 400 in multipsk to use the SNR measurement of the slave station and signal the master to switch to a slower/faster speed when indicated ?
Re: [digitalradio] ALE 400 auto speed change
Hello Rick, Note that the bandwidth is perhaps five times wider for 2 1/2 times more throughput. Normally it would be possible to have a 2000 Hz ALE at 250 bauds instead of 125 bauds. For, I suppose, a reason of frequency diversity, the shift between two adjacent tones in ALE is twice the baudrate (when the minimum between two adjacent tones would be a shift in Hz equal to the baudrate). However for big transfer speeds, there are the choice between several solutions, for example: * something close to the 110A solution: one carrier modulated at 2400 bauds 8ary PSK and different configurations (but with a necessary equalizer and some regular known data to supply the equalizer), * or many carriers modulated in BPSK (or QPSK) as with MT63, but a weak crest factor and no need for an equalizer. 73 Patrick - Original Message - From: Rick W.

Re: [digitalradio] ALE 400
Hi John and group, I have written these frequencies down on a card here in the shack so I can easily refer to them. They are quite different from the ALE400 frequencies that Bonnie invented, but to me are just as valid as long as we can agree on one spot frequency per band. One nice thing is that you only need to know the dial frequency because this mode defaults to an audio center of 1625 Hz. Now, I usually want to use FAE rather than ALE, but I am assuming you are calling in ALE400? I am still not quite understanding when you use ALE and when you use FAE and why. Perhaps if you called up a group call you would need the ALE? Normally, I would call CQ or a specific station which is available with FAE400, but since FAE becomes a connected mode, is that the reason to use ALE400? The disadvantage to using ALE at all, is that it is less sensitive than FAE, but perhaps making a connection on ALE will usually mean that the FAE mode will be even better? I tried calling on the 10136 frequency with VE5MU and also QRZ but no luck so far. For general calls, what should we use? QRZ? Or something else like DRYG (Digital Radio Yahoo Group)? Just kidding. Well ... sort of anyway. 73, Rick, KV9U John Bradley wrote: Happy New Year to all!
