[digitalradio] Pax2 in VK-ZL
I have been reading the posts on pax2 with great interest and I would like to participate in experiments with it. A lot is going on on Europe and the USA on frequencies and times which we here in vk-zl cannot participate. I wonder if there are any other Amateurs in this area with similar thoughts to myself, and if so could we arrange fixed frequencies that would allow us to experiment between each other.

PC-ALE works quite well with my PC and TS440, no need to change anything related to other modes/software. Is it just luck that my TS440 happens to be supported by PC-ALE and therfore does not need modfication, or are there some PC-ALE supported radios that still require one to "modify their already existing interface " ?

A minor programming alteration to PCALE would allow that program to work on my (and most other hams) interface. IF PCale met the pseudo international intefacing standard, then more hams would take up ale, and lets face it PCALE's interfacing is unique in the digital world.

RE: [digitalradio] Re: Another look at ALE
Title: RE: [digitalradio] Re: Another look at ALE There has been some discussion about what mode does what and what is needed/desired. We have had a little discussion on what the problems were during Katrina with digital communications. During hurricanes Katrina and Rita, I worked with a disaster relief group and operated as their HF net control station and a participating station. Our network in Katrina ran from the Mississippi Gulf Coast up to Atlanta back to Louisiana including New Orleans, Batron Rouge, Hammons, Bogalusa and north, Alexandria, Lafayette, Beaumont Texas, Dallas and San Antonio Texas. Most of the time we would have liked to use a keyboard-to-keyboard mode...probably 60% of the time. 20% to 30% of the time Sideband Voice was Ok. But there was 10% of the time when we would have liked to be able to send a rather large data file from our Dallas, San Antonio or Atlanta stations to all of our stations. In many instances conditions were so poor that voice communications didn't work very well at all. Most of the time when sending smaller data packages, reading them by voice worked Ok; however, we have many request for repeats and we had to relay many times. We only operated on three frequencies and primarily on 40 and 75 meters since propagation programs showed that these were the best frequencies to use at the time. I might mention that our net operations and net control stations operate much like a state or local EOC (I worked many years in a large city EOC). When I think of what I would like in a mode to support the type of communications I was involved in (and I think most of the disaster relief agencies such as the Red Cross, Salvation Army and the like), I would like a robust keyboard-to-keyboard mode that would accept typing at about 50-60 WPM. Also a robust mode that could send data files at 200 WPM and be robust enough to work right down in the noise. As far as frequency selection, when you only have 2 bands that will support propagation and use only one frequency on each band, channel selection is not a problem. An automatic call ability, such as SELCALL, would be very nice to have. Most of the other capabilities I hear about are nice but not really needed. I believe that the type of operations I was involved in, and will be again this hurricane season, are useful in passing many if not most types of traffic on HF.

It seems to me that many on this list enjoy the experiments in finding a digital mode that performs well in marginal situations.

Hello John, Glad you succes with Txema.

Of course, a repeater decreases the speed of transmission but increases the distance of transmission.A repeater can be useful but for a first experimentation it's perhaps a bit too much no?In all cases, the Ham in repeater position can show his presence by using the button "Presence" to transmit automatically and periodically that he can repeat frames (as "VE5MU IS READY TO REPEAT PAX FRAMES).>Lowest S/N : - 10 dB for PAX and - 7 dB for PAX2But if the signal during the frame transmission goes below -7 dB and bits are misunderstood, all the frame will be rejected...>How does one LEAVE a message ?When you are connected to the Pax2 responder, all your frames (text only of course) from the moment that you connect to the moment that you disconnect will be considered as constituing your message and will appear on the mail box of the responder.So simply type your message and type the "Carriage return" key to send it and it will be stored by the responder.It is reminded that you can beacon APRS positions + messages (as in Packet APRS but in very long distances).73 and good experimentationPatrick- Original Message - From: "Andrew O'Brien" <[EMAIL PROTECTED]>To: Sent: Monday, March 13, 2006 12:48 AMSubject: [digitalradio] Re: First PAX2 connect>a bit mo
RE: [digitalradio] OK, so do we think PAX2 is any good?
Title: RE: [digitalradio] OK, so do we think PAX2 is any good? I have to jump in here... Any HF digital mode that uses more than 45-50 baud on a single tone carrier that does not have the ability to regress to a 45-50 baud rate is going to get clobbered on HF much of the time. Years of research and experimentation has proven this. Modes like Pactor III and others do this automatically, others have this as a manual capability...but having 125 baud as a fixed rate is certainly asking for trouble on HF.

If I understand it correctly, the PAX modes do use the Olivia 8 tone modulation form. The difficulty that I see is that in order to get a useful throughput (and even PAX2 is not all that fast) the baud rate is very high at 125 baud. Too high for difficult conditions on HFespecially on the lower bands, but can work for higher HF bands with good conditions. 73, Rick, KV9U Andrew O'Brien wrote: >I have played around with PAX2 for 24 hours now.

It seems to me that it offers link abilities, message exchanges , signal information, and much more. I still think ALE is a missed "digital" mode. It is more than "digital", but people here might want to revisit it. PAX2 interest seems to center on the responder/beacon features and the use of the mailbox to contact people not at their desk. ALE's "sounding" and scanning accomplishes much of the aforementioned. There are also some email capabilities and message sending abilities. The scanning, and use of data to determine best path/band, essentially enable someone to "drop by" your station rather than send a message. I wonder why we don't see that much "action" on this reflector when it comes to ALE, but a new mode gets jumped on quickly? Andy K3UK Need a Digital mode QSO?

Re: [digitalradio] Another look at ALE
From what I have read here and elsewhere on ALE, the potential is there, but the software is not. Look forward to new software development ...ALE protocols are only 125 baud (375 bps) and not very wide and not a constant flow (such as MT63, FS-1052, PACTOR etc.) so I do feel that daily use of ALE (but not full multi-frequency Sounding) can be supported on the ham bands with little impact. Its a wonderful way for groups of stations to constantly scan the bands looking for call to then have a QSO in an ALE or other protocol or QSY off to a voice contact, there really is nothing else quite like it and use properly on the ham bands, it has great potential to decrease crowding if you understand its application and apply it properly in my opinion.Sincerely,/s/ Steve, N2CKH/AAR2EYwww.n2ckh.com Need a Digital mode QSO?

Re: [digitalradio] Another look at ALE
Hi Rick, Aside from the limitations imposed on U.S. hams by FCC Part 97 which preclude the use of full ALE Sounding and LQA based calling (which over time may change) ALE can be applied in many ways for Amateur Radio communications and excels as such in a number of ways when you have a properly configured station and trained operator. In my activities with MARS and SHARES where FCC Part 97 does not apply, we are making use of the full potential of ALE and the basic AMD, DTM and DBM FEC and ARQ protocols as well as the MIL-STD-188-110 high speed serial modem (the later does not meet Part 97 either) using FED-STD-1052 Data Link Protocol which together provides for PSK based FEC/ARQ data rates that are in the same ball park as PACTOR III and all using the PC sound device as the modem. In my coding, I have even tailored the MIL-STD-188-110 modem in MARS-ALE so that lessor IF BW's are provided as the standard calls for an 1800hz PSK carrier and the fixed 2400bps symbol rate equates to a 300-3300hz spectrum for a 3Khz BW, most rigs being used by MARS members are ham rigs that can not support that IF BW, thus I have provided for selectable symbol rates and PSK carriers to allow operation in less BW, which of course is fine for MARS-to-MARS, but not directly compatible with most hardware MIL-STD-118-110 hardware modems, it is also a step in the needed direction for use on the ham bands, but not quite enough under the current Part 97. Again, in the MARS program we are using the serial modem up to 2400bps data rate and less than 2.6Khz BW with just a the PC sound device daily, who needs PACTOR III with this ability ? Anyhow, for daily Amateur use on our crowded ham bands we really should be using protocols that offer the least amount of bandwidth and reserve the wider band protocols for the needed speed for training and times of real need for EOC type operations. However, the ALE protocols are only 125 baud (375 bps) and not very wide and not a constant flow (such as MT63, FS-1052, PACTOR etc.) so I do feel that daily use of ALE (but not full multi-frequency Sounding) can be supported on the ham bands with little impact. Its a wonderful way for groups of stations to constantly scan the bands looking for call to then have a QSO in an ALE or other protocol or QSY off to a voice contact, there really is nothing else quite like it and use properly on the ham bands, it has great potential to decrease crowding if you understand its application and apply it properly in my opinion.

Re: [digitalradio] Another look at ALE
I think that many of us have played around a bit with ALE but not found it very compelling as a mode. It may be useful for applications where you have users who do not understand HF propagation and who just want to make a connection automatically. This is perhaps more common for military or government use. One possible value would be to use it as a way to make contact with others who might want to switch to other digital modes since with the plethora of so many modes now, it gets difficult to even know where anyone might be at a given time with a given mode. ALE does use a fairly high baud rate, so it would seem that conditions would have to be fairly good to work well on HF. Since we are always looking for a new digital mode that can work better and faster than existing modes, that is why the interest in anything new. ALE doesn't satisfy that particular need, but perhaps it may be used for some niche purposes. 73, Rick, KV9U Andrew O'Brien wrote: >With the interest in some of PAX2's capabilities, I wonder if folks >here have forgotten about ALE?

[digitalradio] Digital Freq's
Ok so this has probably been asked before, but with all the different modes out now, along with the different programs to use them, where can a newbie get a list of freq's that are used. I know about PSK,RTTY,SlowScan, etc but where do the others hangout like MT63,Oliva,Throb,Chip? The list in the files here is from 2002, so it is a little outdated. 73 Kurt WA8VBX Need a Digital mode QSO?

Re: [digitalradio] OK, so do we think PAX2 is any good?
If I understand it correctly, the PAX modes do use the Olivia 8 tone modulation form. The difficulty that I see is that in order to get a useful throughput (and even PAX2 is not all that fast) the baud rate is very high at 125 baud. Too high for difficult conditions on HFespecially on the lower bands, but can work for higher HF bands with good conditions. 73, Rick, KV9U Andrew O'Brien wrote: >I have played around with PAX2 for 24 hours now.

[...] > [...] > I would dearly love to use the program but until some other > author will take over the development (Charles has ceased > working on it) Hi Kevin, PTT and CAT on the same serial port, in some cases makes it easier to set up for those who only have one serial port (such as laptops). With two serial ports, all you need is a cheap manual DB25 Data switch and a few jumper connections. On HFLINK.COM we will soon have some more helpful info about getting started with PCALE and setting up a ham ALE station. The present version is PCALE v1.061, and it is perfectly usable for amateur radio ALE, if the current fill file and suggested configuration is used as provided on the HFLINK site: Download: http://hflink.com/beta/ Fill file: http://www.hflink.com/beta/HFLINK2005G_v106+01aug05.qrg Configuration: http://www.hflink.com/beta/pcale1061options.jpg The author of the program, Charles G4GUO, is working on a new version of it with significant ham features... multi-ports... better compatibility, and some bug fixes. But please be patient, compared to most amateur soundcard modes, ALE is a more complex system and it takes more vigorous and time-consuming testing to iron out the programming bugs. In the mean time, I would be happy to do what I can to help you get your present system up and running. There are several other VK ops, and lots of others around the world, who would like to link up with you on ALE! Bonnie KQ6XA . Need a Digital mode QSO?
