Re: Why PSK Mode was not recognized yet by eQSL ?

Joe K1YOW
 

My suggestion is to ask them.  When you are in eQSL, there is a SUPPORT hot link.  When QRA64 first started-up, I put in a request to add QRA64 and MSK144, and they said that they would not do in until it was in the ADIF spec, so we had to wait until that was accomplished.  Now the question may come back something like: is there a generic PSK mode?  If folks use, let’s say, PSK31 etc, why would they want a generic PSK mode?  Just thinking out loud.  So they that discussion would follow by asking why would you want a mode PSK to describe SIM31?  I would think that you would want SIM31 as the sub-mode to log, just like one would log PSK31 instead of PSK.  Just thinking out loud.  Joe, K1YOW

Hello All ,
Why "PSK" mode  was still not recognised by eQSL ??  
Only some  old submodes of PSK are recognized but still no PSK main mode...however very new modes as MSK144 and QRA64 are already recognised by eqsl  just after ADIF 3.04 release, just some months ago ??? 

Thanks for discussion.

New release of MULTIPSK (4.32) - AERO

Patrick Lindecker
 

New release of MULTIPSK (4.32)

 

Pour les francophones: la version en français de ce message se trouve sur mon site (http://f6cte.free.fr). Il suffit de cliquer sur le lien "Principales modifications (courriel avertissant de la sortie de la nouvelle version)".


Hello to all Ham and SWL,

 

The new release of MultiPSK (4.32) is on my Web site (http://f6cte.free.fr).
The mirror site is Earl's, N8KBR: http://www.eqth.info/f6cte/MULTIPSK_setup.exe

The MD5 signature of the downloaded MULTIPSK_setup.exe file to, possibly, check (with WinMD5 for example), that the downloading works without error, is equal to: b03f485a095699b92c2791f735ed046a

 

Multipsk associated to Clock are freeware programs but with functions submitted to a licence (by user key).

 

The main improvements of MULTIPSK 4.32 are the following:

 

1) New mode AERO (RX)

 

The Inmarsat "ClassicAero" channel P service consists of downlink messages from geostationary satellites (Inmarsat 3F1, 3F2, 3F3, 3F4, 4F1 and 4AF4) to planes. These messages are transmitted from ground stations (GES) to planes (AES) (but not AES to GES), according to the "Satcom ACARS" system protocol (with "SatCom" for "Satellite Communication" and "ACARS" for "Aircraft Communication Addressing and Reporting System"). ACARS is a data protocol defined by ARINC (Aeronautical Radio, Inc). ACARS is also used in VHF ("ACARS" mode on Multipsk).

 

The Satcom ACARS system is used in preference to standard VHF ACARS when planes are beyond VHF range or if VHF channels are congested, particularly in Europe. The frequencies used are 1545.0 to 1545.2 MHz for 600 and 1200 bauds transmissions and 1546.0 to 1546.11 MHz for 10500 bauds transmissions.

 

The Inmarsat AERO satellites transmit a great number of management frames relative to transmission and satellites link. They are decoded but encrypted. Reversely, several messages are text relative to weather reports (decoded by Multipsk), flight plans, etc.. These are the only messages really interesting.

 

For Hams and SWL, a signal can be received:

·                     either from the discriminator output of a classical UHF FM receiver via a direct connection to the PC sound card (only for 600 and 1200 bauds modes),

·                     or, possibly, from the UHF FM receiver speaker through a simple direct connection to the PC sound card (only for 600 and 1200 bauds modes),

·                     or with a SdR receiver (FunCube Dongle, RTL SDR,...) and directly demodulated (in FM for the 600 and 1200 bauds modes and PSK for the 10500 bauds mode) by Multipsk.

Here it will be found a guide to receive and decode AERO transmissions with Multipsk: http://f6cte.free.fr/AERO_easy_with_Multipsk.pdf

 

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

 

See general specifications further on.

 

2) SDR spectrum analyzer on 250 KHz ("Spectrum SdR" button in the upper left part of the RX/TX window)

 

This application permits to make acquisition of I/Q signals coming from a SdR receiver (RTL/SDR keys only) and to display them under the form of a E = f(F) spectrum with "E" gain in the scale 0 to 1 (or expressed in dB) and "F" the frequency in KHz. The gain corresponding to 1 corresponds to the largest sinusoid being able to be digitalized by the SdR receiver.
A "waterfall" permits, besides, to display the spectrum versus the time, but without large precision.
The SdR receiver frequency (RTL/SDR key) can be directly tuned with a mouse click, either on the spectrum or on the waterfall.

 

This function is useful to have a general view of a wide band of frequencies (250 KHz). For example, to see the low AERO band (1545.0 to 1545.2 MHz), the receiver will be tuned (with the Multipsk "Transceiver" function) in the middle of this band, so 1545.1 MHz.

 

3) Other improvements

·                     Parameters management (in the "Parameters" box of the "Configuration" screen)

The program works with a lot of parameters which can be modified by the user. These parameters are  mainly stored in the CONFPSER.SER file but not only. Some management tools are proposed to the user.

The main possibility is to record all the parameters for a given configuration ("FAX", "VDL2", for example) and to come back, later, to this configuration, with just several clicks. The configurations are stored in the "CONFIGURATIONS" sub-directory of the MULTIPSK folder, as for example: C:\MULTIPSK\CONFIGURATIONS\FAX

·                     Weather (METAR/SPECI/TAF) uplink ACARS messages decoded (on basic specifications only) in the AERO/HFDL/ACARS/VDL2 modes

·                     New sampling frequency of 1 MHz for all modes except ADSB, when a RTL-SDR key is used, the previous 250 KHz sampling frequency introducing noise in all bands

 

Note about TLE files: if you use the "Satellites" option, don't forget to download

(with the "Downloading" button) the 5 recent TLE files (amateur.txt, argos.txt, orbcomm.txt, stations.txt, weather.txt).

 

Note about translation of Multipsk.exe and Clock .exe:  the 4.31.4 version of Multipsk has been completly translated to Spanish by Joachin (EA4ZB), from French. The translation file is on my Web site (http://f6cte.free.fr/Translation_files.htm).

 

 

Description  of the Aero mode channel P (UHF, L band)

 

Baud rate: 600, 1200 or 10500 symbols/second.

 

Modulation :

·                     For 600 and 1200 bauds transmissions, it is used the Aviation-BPSK modulation, called also SDPSK (Symmetrical Differential Phase Shift Keying), i.e. a "0" is transmitted with a -90° shift of the carrier phase whereas the "1" is transmitted with a 90° shift. The transmission could be demodulated in PSK, but it is more simple (even if the minimum Signal to Noise ratio is not so good) to demodulate in FM. This because in PSK, the carrier phase must be followed and locked whereas in FM it is not necessary (the baseband signal is directly supplied). Moreover, for the user, the tuning needs less accuracy.

·                     For 10500 bauds transmissions, it is used the Aviation-QPSK modulation which is a technique which maps a "0" into a 0 degree angle and "1" into a 180 degrees angle or a "0" into a 90 degrees angle and "1" into a 270 degrees angle, alterning between the two options on successive bits. In this case, even if FM could be used, it is appropriate (an error and not PSK leadin to series of errors). So only PSK demodulation is used.

 

Shape of pulse : specified by two templates (upper and lower bounds) for A-BPSK and A-QPSK, to limit spectral occupancy. They seem to correspond to Root Raised Cosine filters.

 

Bandwidth : 800 Hz in 600 bauds, 1600 Hz in 1200 bauds and about 8000 Hz in 10500 bauds.

 

Demodulation : FM (600 or 1200 bauds) or PSK (600, 1200 or 10500 bauds)

 

Bit synchronization : automatic using the signal

 

Data synchronization : an unique word of 32 bits in A-BPSK and 64 bits in A-QPSK.

 

Correction code: no, but a CCITT checksum permits to validate each message of 12 bytes

 

Convolution code:  FEC R=1/2, k=7

 

Interleaving : yes

 

Scrambling: yes

 

Lowest S/N: about +1 dB at 600 bauds, +4 dB at 1200 bauds and +14 dB at 10500 bauds.

Re: QRP test with ROS_HF_4 , 5 MHz Band

The Classic implementation of Spread Spectrum was by  bandwidth modulation , WBFM

The  definitions are unfortunate and  link's to spreading functions, which  are unique to a sub-set of SS techniques, ie,  CDMA , utilising Pn random  number generators , which in turn places the intent at  ''base band   bandwidth  modulated''  'WBFM'   

The  design of the  pseudo random number generators, [ Tap placement ]are  also  defined , assumedly  to ensure 'all could read' the  traffic ,To day this requirement is  circumvented by the  use of the  same  software, 

The  issue is  one of  Legacy management .

The  definitions  are at crossed purpose 

In this case , as  can be  seen the  reference to  ''bandwidth expansion modulation''  is made in the  test of the  'SS'   definition ,  

Where  as the  referral to  ''Heterodyned , non  Base  Band''  '' by modulation of a carrier by some conventional means'' is made in the  text, relating to   'Spread Spectrum' 

The issue remains  one of  legacy  where  ''Bandwidth  modulation and Spread Spectrum''  where uniquely interlinked  

The  entry in the  part 97 sourt to prevent  QRM from bandwidth  modulated systems , which at the  time  of its inclusion , where the  in-use and  in-development systems  of the  day .

The regulation's fail  'simply'  to  differentiate as to where  in the  spectrum. 

''Base band''  or  ''Non-Base  Band''

May be  deployed 

NB The  advent of SDR based  systems , to an extent , negate the  above concept of  definition ,  in that generation may be viewed  as being  base band  , there  not  actually being audio as such to  pass  via  SSB filtering etc, the  systems  being  under  the  numeric  control of the  software ..Third generation implementation ?

Graham G0NBD writes: "part 97 , sites 'Spread Spectrum'  by  name  and then  fails to  define  it"

Part 97 doesn't because the definition of both "Spread Spectrum" and "SS" are in Code of Federal Regulations Title 47 - Telecommunication.

"Spread Spectrum" and "SS" actually mean different things, they are not interchangeable, but they have caused confusion among some amateurs who mix the two up.

FCC Spread Spectrum definition
http://www.gpo.gov/fdsys/pkg/CFR-2012-title47-vol1/xml/CFR-2012-title47-vol1-sec2-1.xml
A spread spectrum system is an information bearing communications system in which: (1) Information is conveyed by modulation of a carrier by some conventional means, (2) the bandwidth is deliberately widened by means of a spreading function over that which would be needed to transmit the information alone. (In some spread spectrum systems, a portion of the information being conveyed by the system may be contained in the spreading function.)

FCC SS definition
http://www.gpo.gov/fdsys/pkg/CFR-2011-title47-vol5/xml/CFR-2011-title47-vol5-sec97-3.xml
(8) SS. Spread spectrum emissions using bandwidth-expansion modulation emissions having designators with A, C, D, F, G, H, J or R as the first symbol; X as the second symbol; X as the third symbol.

FCC Data definition
http://www.gpo.gov/fdsys/pkg/CFR-2011-title47-vol5/xml/CFR-2011-title47-vol5-sec97-3.xml
Telemetry, telecommand and computer communications emissions having (i) designators with A, C, D, F, G, H, J or R as the first symbol, 1 as the second symbol, and D as the third symbol; (ii) emission J2D; and (iii) emissions A1C, F1C, F2C, J2C, and J3C having an occupied bandwidth of 500 Hz or less when transmitted on an amateur service frequency below 30 MHz. Only a digital code of a type specifically authorized in this part may be transmitted.

A mode such as with an Emission Designator of 2K50J2D, such as ROS, is permitted by the FCC on the HF bands.

I see the FCC is now taking action to modernize Part 95 regs, hopefully it won't be too long before they carry out a similar exercise on Part 97.

The TS-590 Family Resources Page -- 1 May update

Ian_Wade_G3NRW <g3nrw-radio@...>
 

The TS-590 Family Resources Page -- 1 May update

First, thanks to everyone who commented favorably on the
new-look site which appeared last month. I do appreciate the
feedback.

Several changes since last time:

* Added a new OTHER HARDWARE section, with links to non-Kenwood
hardware that is either produced specifically for the TS-590
Family or which supports several rigs including the TS-590.
The first new entries cover a TCXO board (Mark Goldberg, W7MLG)

* Added five new entries to the GENERAL TECHNOTES section:
1) TCXO Measurements (Mark Goldberg, W7MLG);
2) TS-590 Oscillator Evaluation (Andy Durbin, K3WYC);
3) Introduction to SDR-based Pandapters Presentation (Andy
Durbin, K3WYC);
4) Prolific 2303HXA/XA Blog (Kenneth Talbott, KE4RG);
5) A TS-590SG/TS-590S Menu Conversion Table (Ian Wade, G3NRW)

* Added a new entry to the USEFUL TOOLS section:
Prolific 2302 Chip Checker

* Updated the CATfix page with a note saying that it runs on
both the TS-590SG and the TS-590S (it transpires that the
already released version of the software did actually run
on the TS-590SG, but I didn’t have an SG to test it on at
the time)


As always, I welcome any new links to documents, slide presentations,
Youtube videos, hardware, software etc. that will be of interest
to TS-590 owners, for posting on the TS-590 Family Resources Page.

Next update should be in early June. Among other items, I plan to
have ready a new program (arcp2txt) that does a full decode of the
settings in ARCP .abk backup files. This will save a lot of time in
understanding .abk files. As a taster, go to:

http://g3nrw.net/ts-590-files/170429%20TS-590SG%20acrp2txt%20output.pdf

for some extracts of typical arcp2txt output.

ARDOP-ALE scanning #ARDOP

Andrew O'Brien
 

FYI, today i am active using both ALE and ARDOP on 7045,10131,14067, and 18091 .  All USB. ALE is doing the "front end" with occasional manual soundings on each channel.  Since I am scanning, an ALE call to me on any of those channels should find me if ther is a path open.  After a link via ALE.. switch to ARDOP for testing of this applications various modes and file transfers.

Both the ALE and ARDOP applications are in "attended" operations but busy detect is also active in both.

Graham,

Thanks for posting this information.  Is there a map that shows Opera-based VHF+ beacons and their frequency?

One more step using Opera at millimetric waves


Last saturday April 8 th we tried a new long distance path across the Ebro river valley, from Pyrenees to

Iberian mountains in Aragón. The distance is 245 Km and the calculated path looses at 47 GHz are about

224dB for 36% air humidity level. That's a huge figure indeed


The two teams at the path were :  Jose EA3HMJ and Iban EB3FRN at JN02SD, with Pascual EA5JF, Maxi EA5CV and Luis  EA5DON at IN91KE


First we made the QSO in 10Ghz with good signals and switched to 24GHz were it was even better later on, using FM for the QSO.


But at 47GHz the signals were very weak. Using the beacons with varactor diodes we

get almost QRO!  with 40 mW 


Modulating the 40mW beacon using  Op05, as the sun rose, causing  the  humidity in the path to decrease,  we started getting decodes .... Best report was -8dB

The new-look TS-590 Family Resources Page is now up and running

The new-look TS-590 Family Resources Page is now up and running at:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
http://www.g3nrw.net/TS-590
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The main reason for changing the format was that the original
site consisted of one single, large, hand-crafted, HTML text
file that was becoming impossible to manage. With the switch
to WordPress, the site now consists of separate pages that are
much easier to handle, and much easier and quicker to edit.

Apart from the new look, there have been several changes from
the old site:

* Repaired several broken URLs

* Added a new “OTHER SOFTWARE” section, including links to
several non-Kenwood software packages for TS-590
management and control. Entries for logging, SDR software
and digital software will follow on a later update

* Added a new entry to the “TS-590SG ISSUES” section on the
reversed cooling fans problem

* Added a new entry to the “HOWTOs” section on generating
clean digital signals. This is a “must see” video from
Nige, G7CNF. Also added a tutorial on getting started on RTTY

* Added new entries to the “GENERAL TECHNOTES” section: 1)
Protective Multiple earthing (PME); 2) FSK interfacing
schematics; 3) TS-590S Data Mode draft 1

* Added a new “FEEDBACK” section, where you can feed back
any comments, ideas, suggestions etc.

* Added a link to other G3NRW websites

* Re-instated the “TS-590SG HOW MANY?” section. This now
includes a form to let you input your TS-590SG serial
number directly

There seems to have been a large drop in the number of
TS-590SGs reported by owners since about the middle of
2016. Please take a look at the back of your rig and
compare the serial number against the table in the
“TS-590SG HOW MANY?” section, for the month of
manufacture. If your serial number is higher than listed
in the table, please fill out the new on-line form with
the details. (Admittedly the numbers are not “official”
Kenwood figures, but they do serve to indicate trends in
the sales of this mighty fine radio, and several people
complained when the section was omitted from the previous
Resources Page update!)


Finally, I hope you like the new site. But don’t be too hard
on me. This is my first attempt at using WordPress — a month
ago I knew nothing at all about it! Please let me know if you
have any suggestions for improvements and additions to the site

Re: ftdx-1200 wsjtx on 5mhz

Ken Meinken
 

Just keep in mind for LEGAL U.S. operation, the audio signal MUST BE centered on 1500 HZ.  Operating at an audio frequency of 700 Hz, 1200Hz, etc. is not allowed by U.S.  (FCC/NTIA) rules.  Yes, I know the rules are being ignored, but that does not make it right and legal.

As published in the Federal Register by the FCC:

20. Operation on Channel Centers. Section 97.303(h) currently requires that amateur operators ensure that their station's transmission occupies only 2.8 kHz centered at each of the five center frequencies. The NPRM proposed that, for amateur stations transmitting CW emissions and PSK31 data emissions, the carrier frequency shall be set to the center frequency. NTIA has requested that the Commission continue to restrict amateur service transmissions in this manner.

21. The Commission adopts the center frequency requirement as proposed in the NPRM. Because the amateur service operates in the 60 meter band on a secondary basis, the Commission pays particular attention to NTIA's position and the interests of Federal agencies that have primary status in the band. The Commission concludes that continuing to restrict amateur stations to transmitting on the center frequencies will maintain the limited number of amateur operators using the five channels at any given time and provide certainty as to where such operations can be found. By not upsetting the expectations of the Federal users of the band, it is confident that they will be able to immediately reclaim these frequencies from secondary amateur radio operations, if and when necessary. Accordingly, the Commission amends § 97.303(h) to specify that control operators of stations transmitting phone, data, and RTTY emissions (emission designators 2K80J3E, 2K80J2D, and 60H0J2B, respectively) may set the carrier frequency 1.5 kHz below the center frequency, and that, for stations transmitting CW emissions (emission designator
