Re: [digitalradio] Re: RFSM 8000

2008-02-01 Thread Rick
Thank you for that information, Dimitry,

When I read over the MIL-STD/FED-STD/STANAG standards, I could not 
understand how these slower modes would work all that well by the 
multi-repeating approach. They repeat multiple times, even if you do not 
need the repeat (sort of a non automatic ARQ) which seemed very wasteful 
in terms of throughput. Especially because this was happening at the 
slower speeds which made them even slower than they might otherwise need 
to be.

When I saw the charts that compare the throughputs with the S/N ratios, 
there was some improvement in terms of weak signal capability over the 
non repeating speeds, but none of the modes seemed to be able to compete 
with Pactor2 speeds at the low S/N levels.

When I have asked those who work daily with STANAG type modems how 
successful they are, they tell me that they often have difficulty with 
certain paths. Also, because they use inefficient document types (MS 
Word .doc files) just to send the shortest possible message can take a 
very long time. They even have some technologies that have duplex voice 
and that does not always work either.

The reason that they use these technologies is because they have to use 
them due to the need for interoperability. In fact, this is now mandated 
more and more with regulations.

I often wonder if they may eventually rethink some of the modulation 
schemes or have a switch over to something that can tolerate severe 
ISI/doppler/  under weak signal conditions that are common with amateur 
signals? The STANAG modem standards do allow for OFDM modems as well, 
but I don't think that anyone switches over to OFDM for part of the time 
when they are normally using a single tone modem. But perhaps the 
standard allows it?

After seeing which modes seem to work the best under the most difficult 
conditions, (well below zero dB S/N) which are the conditions we often 
have with amateur communications, it does seem like a few (two under 
worst conditions) spaced a moderate distance apart, may have the best 
compromise on throughput vs. robustness. That is why Pactor 2 (and 
Pactor 3 when operating in the Level 1 speed) work so well. At this 
time, it does not appear that there is any other mode that can compete 
with that modulation technique based on all the comparisons that I have 
been able to find.

Again, thanks for your help on this.

Re: [digitalradio] Comaparison Table of Major Digital Mode and Logging Apps

2008-02-01 Thread Rick
Hi Phil,

My take is that there is more similarity than difference. Most of the 
multimode digital programs will support the most commonly used modes. 
All other modes are very rarely used and can quickly fall into disfavor.

Consider the primarily used sound card modes, PSK31, MFSK16, and some 
Olivia modes that are used for keyboarding. Other modes that may be 
available include faster PSK speeds up to PSK250, ALE, particularly the 
FAE forms of the 8FSK ALE waveform, Hell, etc. But these modes are not 
that commonly used.

If you like to experiment with the latest technology, then you would 
want Multipsk over all the other multimode programs because only 
Multipsk has these modes available. If you are mostly interested in an 
ultra high quality, polished interface, you would likely consider Ham 
Radio Deluxe/Digital Master 780.

As has been pointed out, both of these programs can interface with DX 
Lab and that will give you one of the best suites available, 
particularly for logging data and handling electronic logging.

Standardizing on one program may be best for most hams because they can 
get better at using a given software program and make the logging easier 
than having logs scattered around on many different programs. I do find 
it difficult to switch back and forth between what I consider to be the 
two main choices.

But then I also am interested in the newer NBEMS concept for emergency 
communications and I tend to favor anything that uses ARQ. Since VBDigi 
(part of NBEMS suite) does RTTY/MFSK/PSK, it actually works FB for much 
of what I do. But then a new mode comes along, and it is often found 
only on Multipsk so you still must use that program anyway for those 
purposes.

At this time Multipsk does not support NBEMS so you have to use the 
NBEMS suite on either Windows or Linux if you want to use that system.

Actually, it is a rather nice problem to have considering that a few 
years ago we only had hardware solutions, and at great cost for modest 
performance.

A tabbing system would certainly be one better way.  I particularly like the
way the the DXLab suite handles the different programs and you can pick and
choose exactly what you do want on the screen.  Its only drawback is it just
doesnt have the capbility of running all the modes that MultiPsk or evn MixW
has. When I wish to use a differnt mode, like those, I use MixW in
conjunciton with DXLabs DXKeeper logging program.  You can also use MultiPsk
with DXKeeper (they say) but I simply dont have the time and do not want to
put in the effort to use MultiPsk with its very confusing screen.

RE: [digitalradio] UI Design

2008-02-01 Thread Rud Merriam
One possibility is for modem developers to no provide a UI. Instead provide
a HTTP or other network interface that can be accessed using web protocols.
The UI is then developed by someone else and hosted in a web browser. 
 
Before I retired my work was with such a system used to monitor corporate
server farms, i.e. 100 or more PC servers in racks. This management system
used a web browser UI to allow access from any desktop. The system monitored
a plethora of information, e.g. temperature, disk capacity and failure
status. 
 
One caution about the UI article: There is a difference between a web site
and an application interface. A web site needs to grab attention immediately
others the user will try a different site. The user of an application will
expend more effort toward understanding the application. The motivation is
higher since a process of download, install, and setup already consumed
effort by the user.

In Multipsk (and perhaps in other soft) this option exists (button 1 CR/LF/72

It might just be that the glass rtty users need to be

dmitry_d2d wrote:

 1. A few words about OFDM and serial tone modem.
 Let's find out how the fight between ISI and Doppler shift
 takes place in these systems. OFDM uses the great number of low
 speed channels so the symbol duration increases. While the
 duration of ISI is much smaller than symbol duration everything
 goes well. Consequently there is an aim to increase the number
 of channels ad infinitum BUT at the same time natural limitation
 takes place. It's just a Doppler shift effect. Hence there is
 always a compromise between ISI and Doppler shift. Moreover we
 should take into consideration a big peak factor which results
 in non-effective usage of power of transceiver. There are
 methods directed at improvement of peak-factor, but the most
 part of them makes the system characteristics worse.
 In case of serial tone modulation the fight ISI with Doppler
 is provided with adaptive algorithms. The more effective and
 faster they are the larger number of Doppler and ISI the modem
 can manage.
 As for RFSM it should be mentioned that now it includes
 rather efficient adaptive algorithms that work properly at a
 speed of 600(500) up to 4800(4000) bps (wide/narrow mode). To
 work at a speed 6400(5333) - 8000() much more compound
 algorithms are needed. In particular using turbo-equalization
 will improve noise proof feature at all rates.
 Therefore OFDM and serial tone modem can be more efficient
 in dependence on channel statement. In my opinion serial tone
 modem with effective adaptive algorithms is the most effective.
 We'd like to mention that under certain circumstances either
 serial tone or OFDM modem can fail to provide connection, for
 example, when the Doppler shift is extremely high (polar
 communications). In that case one should use the methods of
 spectrum spread that extending the symbol in time and
 frequency. Unfortunately the speed would not be high in this
 case.
 So the best way out is to measure the channel
 characteristics and choose the speed of transmission and
 modulation method according to them. The full adaptation of the
 all characteristics is required.

 2. About our users.
 The project RFSM-2400/8000 was initially aimed at
 organizations (not for HAMs)! (First version had no 0,3-2,7
 band, which is adapted for HAMs).
 Its prime value is that high-performance algorithm is used
 in it. Consequently only technical specialists of organizations
 where data (files, mail etc.) transmission through HF is needed
 can estimate the program at its true worth. They need the
 following: high speed of connection and data transmission. They
 are the FIRS GROUP OF OUR USERS. For example there are
 organizations (our users at the moment) who even haven't looked
 upon HAM -modems (little speed, instability, absence of files
 transmission in spite of excellent chat-exchange).
 If you are interested in RFSM as in a program for chat-
 exchange (or even for file transmitting but you do not need a
 high speed) and runner is not important for you:. You are the
 SECOND GROUP OF OUR USERS. $60 may be a pretty penny for this
 product for you.
 There is also not numerous GROUP OF USERS - THE THIRD ONE
 The representatives of this group are specialists in HF-
 radiocommunications and radioamateurs at the same time who is
 interested in algorithms of a high efficiency - the runner of
 the program. May be $60 is rather expensive for them but they
 can trial versions for free. They communicate with us suggesting
 interesting and moreover useful ideas. We really appreciate
 their advices and suggestions. Due to the THIRD GROUP the first
 version of RFSM has transformed in the product adopted for HAM.

 3 . There are several remarks on the open source codes.
 a) RFSM-2400 (and all the more RFSM-8000) is not just a
 dumb modem though such a rate is also possible (it was used in
 PSKMail). Our product is an accomplished system of communication
 that provides different types of services including
 receiving/transmitting e-mail on Internet.
 b) Speaking about OFDM it should be pointed out that we have
 got experience in such a kind of modulation and can remark that
 to construct this modem is incommensurably easier than Serial
 Tone Modem. But the modem of this kind doesn't compare with RFSM
 characteristics. If we were not be able to realize Mil-STD
 correctly and use OFDM in RFSM, we would not be sorry to
 distribute source codes.
 c) Philosophy. Professional free software is possible
 because qualified developer has been grown up by certain
 company. The buyers have already paid for software and
 progressive developer as well. Then at the same time free
 software appears (like RFSM-2400) - like an ad, to create an
 image or ease consumers' tasks. The fact that software is free
 is a result of successful sales of developer. However free
 software is not possible in fact. The bigger the quantity of it
 the poorer it's quality. So said Write on C++ for food ;)
 There is also rather INTERESTING free

What is the digital station on 5366.5 KHz? It appears to cycle through
 several different modes.

Re: [digitalradio] RFSM8000 Mail Server

2008-02-01 Thread Leskep
Hi Howard

The RFSM mail server can send email - originated by any outstation
which can connect to the Mail Server by radio - onto any internet mail address 

Any mail coming from an internet mail address and addressed to the
servers email address in the To line and then addressed to the
callsign  (in the Subject line) of any remote which can connect to the server - 
will be placed
in its  Mailbox on the server for collection by that station as required
[Delivery to multiple (callsigns) or email addresses is handled bothways

Attachments can be included

Just the action of connecting  to the Server by a remote station will create a 
mailbox 
in the name of the connecting station on the server

When a remote station sends an email to the server a folder called OUT_EML is
created as a subfolder of that callsign and the outgoing mail is picked up from 
there
at the time determined in the server Setup - every X minutes 

See using e-mail.txt in the README folder in RFSM8000

Hope that explains it enough for you

Can anyone comment about the RFSM8000 mail server? Would this work in
an emergency as an adhoc email gateway server? Does it need routing
tables to determine how to deliver email (especially local email)??

It would be great to find a description of this.
