Re: [digitalradio] New release (4.18) of MULTIPSK

[John Becker, WØJAB]

Over the course of my work as a 2way radio tech I have looked
at a lot of circuits for one project or another your's being one of them
Very interesting how you made that puppy. Also just about an hour
ago my radio went off.

John,

I have written up a short story of how the weather alert radio industry began.

  Sometime I would like to hear how it all started.
  Bet you could write a book on that.

I did and I do thank you for your afford.
Here in the center of Tornado Alley there is one on
every headboard (or should be) .

Hello Skip,

I ignored that you worked on that subject. Congratulations for the patent and 
nice that you sell a lot of these radios.

The SAME system is an excellent idea. Even if there is no CRC, as 3 same 
messages are sent, a 2/3 logic permits to have a robust decoding (the 
probability of false detection in a 2/3 logic being extremely low).

  Hi Patrick,

  Wonder if you happen to know that I created the original (very first) Weather 
Radio Alert in 1974, which then created the entire weather alert radio 
industry! At that time, there was no SAME feature, so the alarm went off too 
often when no bad weather was close by. SAME came along after I retired.

  The key to making the alert reliable was this patented circuit:

  
http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=/netahtml/PTO/search-bool.html&r=8&f=G&l=50&co1=AND&d=PTXT&s1=4,158,148&OS=4,158,148&RS=4,158,148

  After manufacturing and selling over 3,000,000 radios in 10 years, I retired 
and had time for ham radio. DigiPan was the first thing I did after I retired. 

  Your support of the weather alert feature means a lot to me! Thanks!

Hello to all Ham and SWL,

The new release of MultiPSK (4.18) is on my Web site 
(http://f6cte.free.fr). It is not yet on Earl's and Terry's WEB sites.

The main modifications of MULTIPSK 4.18 are the following:

1) Decoding of the NWR SAME mode

NWR (National Weather Radio) SAME (Specific Area Message Encoding) is 
simply a method of identifying the local area to which an alert message 
applies. It utilizes a digital data stream that contains the alert message with 
information about the type of event expected, its timing, duration, and 
location. The NWR SAME system is used in USA and Canada, in VHF (162.400, 
162.425, 162.450, 162.475, 162.500, 162.525, 162.550 MHz).

To listen NWR SAME messages: the NWS tests the NWR and SAME alerting 
technology weekly. These tests normally occur on Wednesday between 10 AM and 
Noon with some variations to accomodate local requirements.




This mode is available for licencied copies, only (otherwise, the decoding 
is stopped after 5 minutes). 
See specifications further on.

2) Transmission/reception of ARQ FAE QSP (indirect) mails through a "mails 
Server"

Differences between a direct mail and a QSP mail (indirect)

A mail is direct if you can transmit it directly to the final addressee: A 
-->B.

If you can't transmit the mail directly because the final addressee can't 
be directly reached due to the link conditions, the mail can be forwarded by 
the connected station, which acts as a "mails Server": A-->C (mails 
Server)-->B. 

For this, you must use a QSP mail.

A paper based on snapshots presents this new system:


http://f6cte.free.fr/QSP_mails_forwarding_easy_with_Multipsk_in_ALE_and_ALE400.doc

3) New macros:

-  permits to ask to the other Ham or to the SWL monitoring your QSO 
to send you a reception report by e-mail. Your address must be specified in the 
"WEB ADDRESS" of your personal data ("Personal" button). It will be transmitted 
the following command "r...@lenemail addressCRC" which is the report demand. If 
correctly decoded, a reception report will be transmitted to the e-mail address 
that you specified, through Internet.

Examples of use of this macro

1) The main objective is to ask the other Ham with whom you are in QSO to 
send you a reception report by e-mail.

2) But it can be also done by a SWL monitoring your QSO.

3) This macro can be used in conjuction with a Multipsk beacon which mode 
can be controlled by a RS ID. For example, you can switch the beacon in BPSK31 
and asks the beacon for a reception report. Afterwards, the beacon can be 
switched in Olivia by a new RS ID and a new reception report can be asked...

Note: this macro can be used for all digital modes (except JT65), CW 
included.

A paper based on snapshots presents this new system:

http://f6cte.free.fr/How_to_use_the_« RPRT@ 
»_email_reception_report_with_Multipsk.doc

The source code (in Pascal/Delphi and in English) to code/decode this 
command is available for the coding/decoding software developpers, by making 
the demand to F6CTE by e-mail.

-  permits to send a Tune (non modulated carrier) with the 
command:
