New Beta Version WSJT-X 2.0 !

QRZ Now - Thu, 09/20/2018 - 11:41am

As promised, the WSJT-X Development Group has announced a new “candidate release,” WSJT-X 2.0 rc1. This beta version of the popular digital mode suite incorporates many new FT8 and MSK144 features that will be of particular interest to the Amateur Radio contesting community. It incorporates all FT8 DXpedition Mode changes already developed in WSJT-X 1.9.1.

“Enhancements to the FT8 decoder ensure that in most situations decoding sensitivity is slightly better than for the old protocol. Symbol rates and occupied bandwidths are the same as before, and false-decode rates are significantly lower,” the user notes explain. “The decoding threshold for MSK144 is a fraction of a dB higher than before, owing to the slightly larger message payload and higher code rate.” WSJT-X 2.0 introduces no significant changes to the JT4, JT9, JT65, QRA64, ISCAT, Echo, or FreqCal protocols.

The new features are summarized on the WSJT-X website and in the Quick-Start Guide to WSJT-X 2.0. Contest-related changes include:

  • Support for standard ARRL Field Day exchanges, such as 6A SNJ.
  • Better support for North American VHF contests with improved handling of grids and /r rover call sign designators.
  • Six-character locators and call sign suffix support for portable operators, focused on EU VHF contesting
  • Support for standard contest exchanges in the ARRL RTTY Roundup, such as 579 MA or 559 0071.
  • Support for call signs of up to 11 alphanumeric characters, to accommodate non-standard and compound call signs.

Support for new exchanges should expand the ability of contesters to use FT8 and other WSJT-X protocols during contests that allow digital contacts and where the exchanges is a traditional signal report and state/province/country.

According to the release notes, WSJT-S 2.0 also offers “significantly better sensitivity” (about 1 dB) for the WSPR decoder. In addition, color highlighting of decoded messages provides worked-before status for call signs, grid locators, and DXCC entities on a by-band basis.  Color highlighting can also identify stations that have — or have not — uploaded their logs to “Logbook of The World” (LoTW) within the past year.

For the convenience of beta-testers, the –rc1 and –rc2 releases will offer receive and transmit capability for both the new FT8 protocol and the older one. Starting with –rc3 and the full release of WSJT-X 2.0, only the new protocol will be supported. zIn contrast, the new MSK144 protocol replaces the old one from the outset, with no backward compatibility.

Those participating in WSJT-X beta tests are expected to report their experiences to the developers and upgrade to the general availability release when it becomes available. Visit the WSJT-X web page for more information.

LA1K5 is a solid-state 1200 watts 1.8 – 54MHz power amplifier

QRZ Now - Wed, 09/19/2018 - 4:08pm
The RFpower LA1K5 is a solid-state 1200 watts 1.8 – 54MHz power amplifier. It uses a ruggedness 1800 watts 65 V LDMOS technology NXP’s MRFX1K80 RFpower device for reliability and high spectral purity and has an internal highly reliable, Power Factor Correction, low-noise switching power supply, in order to reduce the overall weight. At last, but not last, the switching power supply meet the severe European Rules about Energetic Efficiency.   The thermal design is very conservative due to a special 6 kg weight copper/aluminium heatsink. This, assisted by a sophisticated thermal management system, allow the channel temperature of the LDMOS device to remain within limits which should ensure extended life.   A major objective of the RF design has been to significantly exceed the RF spurious signal generation requirements of the European Rules (RED Directive) for amateur radio equipment. To this end the RFpower LA1K5 has more extensive filtering than is usual in HF amplifiers. An efficient internal ALC circuit contributes so that the RF output signal is even more clean.   While LDMOS RFpower Mosfets are amongst the most rugged RF power amplifier devices currently available, they are sensitive to RF overdrive. The RFpower LA1K5 has both extensive monitoring to minimise the risk of damage by overdrive and a conservatively designed input circuit.   The RFpower LA1K5 employs a full touch-screen control using a 800×480 pixel 5.0″ full colour TFT display module. A wide range of monitoring functions can be displayed with high precision, including RF output power, RF input power, Antenna VSWR, PA drain current, PA drain voltage, LDMOS temperature and more.   Band selection is fully automatic by RF-sense circuit. The presence of valid in-band signals is detected and will initiate switching automatically to that band. For a more high speed band selection, Kenwood CAT Command, Yaesu Band Data Input and Icom Band Voltage Input are included.

WSJT-X 2.0 – New 77-bit messages information update

QRZ Now - Tue, 09/18/2018 - 3:15pm

“Hi all,

Many of us have made many QSOs using the new 77-bit messages on 7.078 and 14.078 MHz. Overall the results have been good — but not surprisingly, bugs are being identified. Several are important enough to warrant a second candidate release well before the originally suggested target date, October 15. We will make a suitable announcement here, after things have settled down a bit.

Many have noticed signals in the 7.078 and 14.078 MHz sub-bands that look like FT8 but are undecodable. These appear to be “FT8CALL” 
signals. FT8CALL is *not* FT8 — and probably it should not have “FT8” 
in its name. It appears that the author of FT8CALL did not bother to select a different Costas array for synchronization. If the legacy FT8 decoder is enabled, WSJT-X will waste time fruitlessly trying to decode these non-FT8 messages.

For the record, and to avoid the necessity for multiple posts on the same issue, here is a list of currently known bugs:

1. If a message’s first callsign contains only characters 0-9 and A-F it will be interpreted as a hexadecimal number. The message will be transmitted and decoded as if the first callsign were telemetry data; the remaining parts are lost. (Apologies to holders of all such callsigns… we’ll fix this very soon.)

2. Some nonstandard callsigns (for example, 8Z88ND) are not recognized as nonstandard. Consequently the auto-generated messages do not include <…> brackets, and free-text messages are improperly sent. (Again, our
apologies…)

3. Bare CQs (with no grid locator) are flagged as new DXCCs.

— 73, Joe, K1JT”

Introduction to APRS- the Automated Packet Reporting System

QRZ Now - Mon, 09/17/2018 - 5:20pm

“The Automated Packet Reporting Service is a digital real-time communications system to share tactical information and messages. The most common activity in APRS is to plot the location of moving objects using GPS information, but APRS can also be used for short messaging, weather station telemetry, announcements, and displaying objects on a map. The power of APRS is its ability to geocode objects and display that information in a meaningful way using mapping technology. So it’s an excellent technology to use for tracking assets: like checkpoints or runners in a marathon or storm spotters for a SKYWARN activation…..READ MORE

WSJT-X Version 2.0.0-rc1 Released – Download FT8

QRZ Now - Mon, 09/17/2018 - 2:30pm

Go to New Features in WSJT-X 2.0 for a detailed description of its new features.  Further technical information (primarily of interest to programmers) is available here.

Release Schedule: Because the FT8 and MSK144 protocols will not be backward compatible with those in Version 1.9.1, there will be a staged schedule for testing and eventual release.  Target dates for candidate releases are as follows:

  • September 17, 2018:   -rc1        Expires October 31, 2018
  • October 15, 2018:       -rc2        Expires November 30, 2018
  • November 12, 2018:    -rc3        Expires December 31, 2018
  • December 10, 2018:      GA        Full release of WSJT-X 2.0

Candidate Release -rc1 for WSJT-X 2.0
Candidate releases are intended for beta testers: individuals interested in testing the program’s new features and providing feedback to the WSJT Development Group.  At the time of this first candidate release we have not yet completed the WSJT-X 2.0 User Guide.  Potential users of the candidate release should read Quick-Start Guide to WSJT-X 2.0 before proceeding.

  • New Features in WSJT-X 2.0
    September 17, 2018
    ————————–This document is an update to the white paper “Plans for WSJT-X
    Version 2.0″ that was publicly distributed on July 26, 2018. It
    describes the most important enhancements in WSJT-X 2.0 relative to
    version 1.9.1.A majority of new program features involve the FT8 and MSK144
    protocols. Both modes have been upgraded to use use 77-bit
    information payloads rather than the 75 bits of the older FT8 protocol
    or 72 bits of JT4, JT9, JT65, MSK144, and QRA64. Cyclic redundancy
    checks (CRCs) that protect against false decodes have been increased
    from 12 to 14 bits (FT8) and from 8 to 13 bits (MSK144). These
    changes bring many benefits, including support of structured messages
    optimized for the following special types of QSOs and exchanged
    information:1. NA VHF Contest operation with full and transparent support of grid
    locators and “/R” (Rover) callsigns

    2. EU VHF Contest operation with the exchange of 6-digit locators, QSO
    serial numbers, and “/P” (portable) callsigns

    3. ARRL Field Day operation with standard Field Day exchanges such as
    “6A SNJ”

    4. ARRL RTTY Roundup operation with standard contest exchanges such as
    “579 NJ” or “559 0071”

    5. Compound and nonstandard callsigns (up tp 11 characters); no need
    for distinctions about “Type 1” or “Type 2” prefixes/suffixes

    6. A special “telemetry” message format for exchange of arbitrary
    information up to 71 bits

    7. All features of FT8 DXpedition mode, as in WSJT-X v1.9.1

  • Enhancements to the FT8 decoder ensure that in most situations
    decoding sensitivity is slightly better than for the old protocol.
    Symbol rates and occupied bandwidths are the same as before, and
    false-decode rates are significantly lower. The decoding threshold
    for MSK144 is a fraction of a dB higher than before, owing to the
    slightly larger message payload and higher code rate.

    OTHER PROGRAM ENHANCEMENTS: WSJT-X 2.0 has several other new features
    and capabilities. The WSPR decoder has significantly better
    sensitivity, by about 1 dB. Color highlighting of decoded messages
    provides worked-before status for callsigns, grid locators, and DXCC
    entities on a “by band” basis. Color highlighting can also identify
    stations that have (or have not) uploaded their logs to “Logbook of
    the World” (LoTW) within the past year. (Recent information from LoTW
    for this purpose can be downloaded from the ARRL web site.)

    WSJT-X 2.0 introduces no significant changes to any of the modes JT4,
    JT9, JT65, QRA64, ISCAT, Echo, or FreqCal.

    IMPORTANT: For the convenience of beta-testers, the first and second
    release candidates — releases with “-rc1” or “-rc2” in their names —
    will have Rx and Tx capability for both the new FT8 protocol and the
    older one. Starting with the third release candidate (“-rc3”), and in
    the general-availability full release of WSJT-X 2.0, only the new
    protocol will be supported. In contrast, the new MSK144 protocol
    replaces the old one from the outset, without backward compatibility.
    To minimize on-the-air confusion, it’s important that users be aware
    of these distinctions and the schedule for release of WSJT-X 2.0, as
    detailed below.

  • MESSAGE FORMATS: The following table shows examples of message formats
    supported by the new FT8 and MSK144 protocols. Parameters i3 and n3
    (shown in the first column) are used in the software to define major

    RELEASE SCHEDULE: Candidate releases of WSJT-X 2.0 will have built-in
    expiration dates after which they cannot be used. Target dates for
    planned releases are as follows:

    September 17: -rc1 (expires Oct 31)
    October 15: -rc2 (expires Nov 30)
    November 12: -rc3 (expires Dec 31)
    December 10: GA Full release of WSJT-X 2.0

    WSJT-X 2.0-rc1 provides the first chance for beta testers to use the
    new 77-bit messages. It supports the old (v1.9.1) FT8 protocol as
    well as the new message types illustrated above. To avoid QRMing
    legacy FT8 users with incompatible messages they can’t decode, and to
    help concentrate testing activity into a few sub-bands, we recommend
    using the new FT8 capabilities on the 40- or 20-meter bands at dial
    frequencies 7.078 or 14.078 MHz. These frequencies are offered as FT8
    alternatives on the drop-down frequency-selection control on the main
    window.

    The new MSK144 is fully functional for QSOs between any two stations
    using a WSJT-X v2.0 release. MSK144 is not backward compatible with
    earlier program versions. Therefore during the testing period,
    approximately Sept 17 through December 10, we recommend using the new
    MSK144 capabilities on 50.380 MHz (IARU Region 1) or 50.280 (Regions 2
    and 3). By specific arrangement, or as soon as most regular users
    have upgraded to a v2.0 release, MSK144 activity can be moved back to
    50.360 (Region 1) or 50.260 (Regions 2 and 3).

    By design, our proposed release schedule will make WSJT-X 2.0 usable
    for all relevant ARRL operating events and Eurpoean VHF contests after
    January 1, 2019.

FCC Grants ARRL Temporary Waiver Request to Permit PACTOR 4 Use in Hurricane Relief

QRZ Now - Sun, 09/16/2018 - 9:40am

The FCC has granted an ARRL request for a temporary waiver of Section 97.307(f) of the FCC’s Amateur Service rules to permit the use of PACTOR 4 digital mode for Amateur Radio communication within the continental US related to Hurricane Florence relief. The grant extends through Tuesday, September 18, and a formal order addressing the request for a 30-day waiver will be issued next week, the FCC said.

Section 97.307(f) of the Commission’s Rules limits the digital data emissions of amateur stations operating below 28 MHz to a symbol rate not to exceed 300 baud, and in the 10-meter band (28.0 – 28.3 MHz) to a symbol rate not to exceed 1200 baud, thus precluding the use of PACTOR 4.

PACTOR 4 is a data protocol that permits relatively high-speed data transmission in the HF bands, and many amateur stations active in emergency communications preparedness are capable of using PACTOR 4, which was used to great advantage, pursuant to FCC temporary waivers, in Hurricane Maria relief efforts, and, more recently in preparing for typhoon relief communications in Hawaii.

“ARRL has recently dispatched equipment to the Carolinas and is actively preparing to assist radio amateurs involved with the Amateur Radio Emergency Service and otherwise to conduct disaster relief communications,” ARRL General Counsel Chris Imlay, W3KD, told the FCC in requesting the waiver. The equipment includes PACTOR radio modems with PACTOR 3 and PACTOR 4 capabilities.

ARRL’s request proposed limiting the use of PACTOR 4 to radio amateurs in the Continental US who are directly involved with the hurricane relief efforts involving the US mainland. “This request is without prejudice to the resolution of Docket 16-239 [the so-called “symbol rate” proceeding], which is presently pending and addresses the rule section discussed herein,” Imlay added
