Re: [digitalradio] Time to do something real with ALE400 ?
ALE 400 is a subset of wideband ALE, so wouldn't we expect even fewer participants? Even regular ALE has very little activity from what I and others have been able to measure on actual on the air use. Hams that use hardware embedded wideband ALE are not going to be using ALE 400 without a separate computer. While I do not recommend anyone buy such rigs due to the rapidly changing technology that can make such modes obsolete, there are probably only a handful of hams who have these kinds of rigs. But if hams stay on wideband ALE, then that reduces the practical use of ALE 400. Ironically, ALE 400 is very much better in performance than wideband ALE since it can work deeper into the noise. It has a much more appropriate footprint for use in the narrow text digital parts of the bands. The slower speed may be mitigated by the fact that it can work when wideband ALE does not get through at all. I would propose that wide band ALE should only be used in the wide bandwidth voice portions of the bands and ALE 400 be used in the narrower text digital portions. The last thing we want to see happening is someone operating on a 400 Hz wide mode and then switching suddenly to a 2000 + Hz mode and causing severe interference to other stations. My experience has been that 2000 Hz modes are difficult to place without causing problems in the shared service of amateur radio. I am not sure that there will be many of us operating ALE 400 (or wide band ALE) anyway. I know that I would have no interest in tying up my rig with scanning the bands since I can not be doing that and also operating my normal HF activities. When I have used the narrow 8FSK50 mode, it has almost only been on FAE 400, the ARQ version of ALE 400. Perhaps some of us envision using the FAE 400 mode to send error free data to other stations on HF and do it with a relatively narrow footprint available on a MS Windows computer using a soundcard. While there is an ARQ mode available on PSK with Linux OS, it does not seem to work very well when you compare it to the 8FSK50 waveform of FAE 400. What might be practical though, is to have some spot frequencies that we could use for ALE 400/FAE 400 calling and chatting? Since it is relatively narrow, perhaps up 5 kHz from the normal PSK31 frequencies? Since there seems to be a standard 1625 Hz center frequency, the frequency is the same as the dial frequency. 73, Rick, KV9U Andrew O'Brien wrote: I think many people have had time to experiment with ALE 400 in ARQ mode and the feedback about the throughput has been very good.

[digitalradio] Time to do something real with ALE400
I agree that we have all had a great time fooling with the mode, and VE5TLW and myself have been using ALE400, together with Outlook express to pass messages, both ALE 400 and 141A. It is a terrific piece of software and bodes well for the future. In the next few days we will have this software set up at an Emergency Operations Center (EOC) , running 24/7 with the added feature of being able to remotely access the desktop , to maintain the software and further experiment with it. Call is VE5GPM. I am not a fan of PCALE , for a couple of reasons, not the least of which, given that I am reasonably bright, not being able to get it running with my TS480SAT. From what I can see so far, it scans really well , but have no idea of how well it would pass messages. Is there two different versions of PCALE, one that we find on the ham bands and one used for MARS operations? And what are the differences? Is the intention with PCALE to establish which band/frequency has the best path and then use another mode for passing traffic? In all my listening to ALE frequencies I have not heard any PCALE message traffic, just lots of soundings. I'm certainly up for nets and further work with ALE400, and side by side comparisons to PCALE if I can ever get it to work. I'm also open to where we should part our EOC station on anything between 80 and 20M . As Canadians, we have a bandwidth restriction on 30M to 1khz , which cuts out the use of 141A there. Comments?

Re: [digitalradio] Time to do something real with ALE400
My 2 cents/pence/yen worth: I think one of the biggest drawbacks to the ALE modes in Amateur use is the complexity and bewildering number of options, calling methods and messaging types. It's just not going to gain any real traction without it being simple to use. PSK31 is the poster child for digimode communication. It needs to be as easy as that or it won't get a second look by most hams. I personally think the ALE400 FAE ARQ submode is a very worthwhile development and an acknowledgment of the genius of the inventor Patrick Lindecker. I would love to see it in a stand alone simplex version - perhaps an Easy ALE mode developed along an open source approach and incorporated into other software eg FLDigi, DM780 and MixW. This would give a farily narrow, sensitive and easy to operate ARQ mode which has been lacking on the Amateur bands since the soundcard revolution. It should be as simple as Pactor or AMTOR to initiate a call. I also agree with Rick that the wide band version would probably be best suited for the voice portions. It just isn't compatible on many bands in the narrow digital areas. 73 Sholto KE7HPV. - Original Message - From: John Bradley [EMAIL PROTECTED] To: digitalradio@yahoogroups.com Sent: Tuesday, December 11, 2007 10:05 AM Subject: [digitalradio] Time to do something real with ALE400 I agree that we have all had a great time fooling with the mode, and VE5TLW and myself have been using ALE400, together with Outlook express to pass messages, both ALE 400 and 141A.

Re: [digitalradio] Time to do something real with ALE400 ?
Hello Andy, Hereafter is a non exhaustive list of the ALE400 frequencies (proposed by Bonnie): 1837.0, 3589.0, 7037.5, 10141.5, 14074.0, 14094.0, 18104.5, 21094.0, 24926.0, 28146.0, 50162.5, 144162.5 (AF at 1625 Hz). The complete list of frequencies is on http://hflink.com/ale400;. So for 40, 30, and 20M, it would be 7037.5, 10141.5, 14074.0. These frequencies must be entered in the Options window, for an automatic scan. Note: the features are the same in ALE and ALE400 (which is strictly an ALE at 50 bauds with 50 Hz between carriers). About open source of ALE or ALE400 and ARQ/FAE: There is no open source but the specifications are public. The only difficult point of ALE/ALE400 was the CRC calculation (DTM/DBM) which is very fuzzy in the specifications. I have supplied my code about this CRC calculation (HFLINK and Multipsk Yahoo group) so that the programmation of these modes is normally no so difficult (and it can be answered to questions in the HFLINK group) . 73 Patrick - Original Message - From: Andrew O'Brien To: DIGITALRADIO Sent: Tuesday, December 11, 2007 3:27 AM Subject: [digitalradio] Time to do something real with ALE400 ?

Re: [digitalradio] Time to do something real with ALE400
Hi John, If you are using PC-ALE 1.062H ( the latest build being #5) I can not imagine why you are having any issues with your TS-480SAT if the CAT control of radio works otherwise with any other software. All you need to do is select either KENWOOD or if using CTS/RTS handshaking, KENWOOD_HS to begin with. If your radio is setup to use the long standing 4800 baud for Kenwood radios for backward compatibility with older software tools, then that is all you need to do aside from selecting the com port for Radio CAT and your PTT interface choice. If you are using higher then 4800 baud, then you need to click the Radio Port button next to the Radio Type selection and configure for the RS-232 port parameters that you are using. Upon proper setup, shutdown and restart PC-ALE, if should come up and tell what Kenwood model you are using from the radio ID, if for some reason it can't, it will state UNKNOWN and treat the radio as the newest Kenwood model the software knows about, which just happens to be the TS-480. MARS-ALE is a based on PC-ALE to meet the needs of MARS operations and differs from PC-ALE in many ways. /s/ Steve, N2CKH At 01:05 PM 12/11/2007, you wrote: I am not a fan of PCALE , for a couple of reasons, not the least of which, given that I am reasonably bright, not being able to get it running with my TS480SAT.

Where on the bands can this mode be found? And does it sound like Pactor / Amtor ARQ ?
Re: [digitalradio] ALE400
Hi John, We don't have any specific places we have been operating, although I made a suggestion on the HFDEC yahoogroup (Hams for Disaster and Emergency Communications), that perhaps we could operate up a ways from the typical PSK31 watering holes. My suggestion, and it is only a suggestion, is up 5 kHz, so 3585, 7075, 10145, and 14075? Or perhaps some other frequencies if these interfere with something. The sound is not like regular 141A ALE since it is 2.5 time slower. Even though it is not as fast as 141A ALE, since it is much more robust, it gets through when 141A can not. Generally speaking, 141A ALE is fairly old technology now, and can only work a few dB below the noise. FAE 400 is even more robust than ALE 400 (apparently due to memory ARQ as implemented in Pactor) and seems to work as well as, or even better than PSK31. And while the bandwidth is much wider than PSK31 (about 400 Hz vs only 60 Hz) you get solid error free copy with no hits. The feel of the modes is amazingly similar to Clover II. It uses an asynchronous ARQ, so there is no constant back and forth transmission, even when nothing is being sent. It sends only when there is something to send, or when it needs to retry. I have always found it really neat how fast the other station can automatically respond to a burst of data. Very much the same thing as when we tested the high speed (~ 1000 wpm) SCAMP mode a few years ago. 73, Rick, KV9U John Becker, WØJAB wrote: Where on the bands can this mode be found?

Patrick, It is my understanding that 7040 in the US and 7035 in Europe are both QRP watering spots where many are using crystal control, low power, and cannot relocate.

I had forgotten that Bonnie had taken the time to establish some suggested frequencies, thanks Patrick (and Bonnie). I agree with Rick , I am also not likely to have a dedicated rig scanning full time. But what about 2-3 frequencies that we scan when we want, looking for traffic or sounding for a brief while ? Anyone want to suggest the three frequencies ? I can see myself scanning for 30 minute periods every now and again. Also what about a net periodically, not a chat net, perhaps a net where NCS sends out a bulletin to those on frequency via Netcall.
