Notice Board

Amateurs must never accept bullying, discrimination and/or bad behaviours from other Amateurs - No matter how influential and/or "big name" they may be.

Use email (from qrz.com etc. for addresses ) to make contact if you experience behaviour that offends you. Tell them that their behaviour is unacceptable.

Keep comments off airwaves if you can (though QSY notes if requried are ok).

The message may get through to them eventually !

Please acknowledge all contacts with eQSL's  (http://www.eqsl.net),  LOTW (http://lotw.arrl.org) and QRZ Log (http://logbook.qrz.com).

Do not send money as this is not legal via Australia Post. I will respond as best I can usually through your local QSL Bureau !

----------------------

If you respond to my CQ please follow through... Amateurs that respond to CQ then jump to another caller should have their licenses cancelled. They dishonour their country and other operators from their country.

Listen before transmitting. "Frequency Jumpers" dishonour Amateurs in their country. Telling (especially) FT8 Ops to QSY (and I will) makes me look aggressive - but frankly I work here under very trying conditions and fighting for a patch of clear spectrum to work low-level DX is difficult (and unnecessary).

----------------------

I HAVE REPORTS OF MY SIGNALS BEING WIDE AND DISTORTED. PLEASE EMAIL SCREEN SNAPS OF JT9 / JT65 WATERFALLS IF THIS IS BEING OBSERVED !!

SCREEN SNAPS OF TRACES ARE ALWAYS APPRECIATED AT VK3VM !!

I have refitted RF earths - especially to tuners. This appears to solve issues.

The Tx site is a highly urbanised site in metropolitan Melbourne, Australia - the World's 89th most-populous City. A "tree/sea"-change will be happening soon.

For HF I use a modified 40m quarter-wave (modified "Stationmaster" on the FT-991) with a 20m doublet off its top ! Far from ideal I know !

Please consider this information re my less than satisfactory antenna systems when responding to me or responders who have huge Beams and Arrays.

I am a huge supporter of the JTDX Project. The latest information and downloads can be found at https://groups.yahoo.com/neo/groups/JTDX/info. Information on the base technology, WSJT-X can be found at http://physics.princeton.edu/pulsar/k1jt/wsjtx.html

The JTSDK for building the latest WSJT-X can be found at http://sourceforge.net/projects/jtsdk/. Extract JTDX into the "src" folder of the Windows JTSDK and build it with build-wsjtx package from the JTSDK-QT Prompt. /src

Critical Note for all FT8/JT9/JT65 Users

Please ensure that no ALC is cutting in when you transmit.

Please only use just enough power to sustain reliable contact.

Very-wide signals from poor operators are splattering the hell out of many decent FT8/JT9/JT65 ("JT") operators. When a Transceiver's ALC cuts in (at all) the radio can "mulch" the transmitted JT signals that the radio is being fed with. This results in splatter and interference. Not only are signals taking up more bandwith than they should - masking adjacent weaker signals - but many operators have observed signals "echoing". These "echoes" are independent signals - harmonics - emanating from the over-driven source that grow in width. These harmonics often cross the entire JT areas. These signals always emanate from a JT9/JT65 station that is OBVIOUSLY pushing a signal that is too high in level from the PC into their rig. Often it is clear that these signals have been through linear amplifiers that enhance reproduction of the poorly modulated signals and their unwanted interference products - making matters worse for all operators.

If the ALC meter is showing any deflection on transmission then you are most likely to be causing some form of interference.

If you are sure that you are not overdriving signals and your signals are still not clean, check your RF earth to the tuner and radio !!

Offer constructive assistance to operators that are causing issues. Report arrogant operators who refuse to clean up their act.

----------------------

All Amateurs must keep up with the latest versions of software (i.e. JTDX or WSJT-X). Sometimes slight changes are made that make significant changes (i.e. WSJT-X requiring tighter time synchronisation).

----------------------

Accurate PC time synchronisation is critical with "JT" Modes 

If reliable Internet is available then the Meinberg tool should be used with "JT" software (https://www.meinbergglobal.com/english/sw/ntp.htm​ https://www.meinbergglobal.com/english/sw/ntp-server-monitor.htm ). Dimension 4 can create considerable "time spikes" as it does not tend to average responses before adjusting time ! Time calibration can be checked and set with http://www.fountainware.com/Products/TimeCalibrator/index.htm . Calibrate and operate this for short periods (5 mins only) to time.nist.gov

​The alternative is a "VK-172" Ublox NEO-7M based GPS/GLONASS Module (Approx $US10 posted from Ebay) with NMEATime 2 ( http://www.visualgps.net - $US20). Note that this is what I use; time precision is within the 1 - 5 millisecond range !

Congratulations to the new WIA Board that has been elected. All Australian Amateurs must keep abreast of ALL issues in Australian AR and should endeavour to ensure that this Board is representative of the majority Amateur viewpoint and does not fall into blocks, bickering and nastiness.

The Ensemble RXTX for 40m / 30m / 20m is operational !

The G59 SDR is functioning well; All I need now is debug the 20W Driver !!

Be cautious with FT-897D kits for First IF Taps at T1026.... They can "Kill" Q1013 !!!

And WOW ! The FT-991's Rx is AMAZING! Keep up with Firmware updates, though!

----------------------

Amateurs that call CQ and ignore by function/deliberate/frequency changes - or that refuse to listen first before transmitting - especially using digital modes (i.e. JT9/JT65) to ignore some callers - should HAND BACK THEIR LICENSES and take on activities where they can work in closed, egocentric, individual-based worlds...

AR is about PEOPLE: AR requires some-one transmitting and some-one to listen.

The need for people makes AR unique - AR is a Social, Technical Activity !

The sooner that arrogant ops realise this and start working together, start sharing (eg. stop  skill hoarding and data destruction on SK) and start being PEOPLE FOCUSSED, the sooner AR will GROW, keeping  professional wolves that eye off spectrum away! For AR's sake - CHANGE !

----------------------

I apologise to "regulars" that use JT modes that I often contact; Sometimes regulars are contacted for the purpose of signal analysis and software development.

Also sometimes on quiet bands just the single response to someone calling in the dark (that you know) can open up a whole band !
