CQ WW Online Database extended to 1953

Posted by Trent, VK4TS

N2NC and team have now extended the CQ WW online database back to 1953. Hard to believe there were only 167 phone entries and 187 CW entries back then.



CQ WW Online Database 1953-2013


Total Phone entries 168,423


Total CW entries 166,369


One cool thing to do is to see the winning score every year for any combination of country/category.

Trans Tasman Low Bands Challenge

Posted by Trent, VK4TS

Trans Tasman Low Bands Challenge


Prepared by VK4TS and VK4SN

Last amendment 6th February 2015


1. Contest Introduction

This contest is to encourage Low Band Activity in Australia and New Zealand – The applicable bands are 160, 80 and 40M. The modes are SSB CW and Digital (RTTY and PSK only)

2. Objective

Amateurs in VK and ZL will endeavour to contact other amateurs in VK and ZL.

* VK and ZL, means any station operating within Australia or New Zealand and their external territories.

* Points are only awarded for valid contacts between VK and ZL stations.

The contest is made up of 3 individual two hour sessions – you are able to work another station once per band and mode in every session. Every different Prefix used by VK or ZL stations is a valid multiplier and credit can be claimed once per band per session.

3. Contest Date & Time

The contest is held on the Saturday night of the third full weekend of July Start Time is 08:00 UTC and finish time is 14:00 UTC

4. Categories

A. Single Operator – High Power All Modes All Bands
B. Single Operator – Low Power (100 watts)
C. Single Operator – QRP
E. Multi-Operator – Single Transmitter
F. Multi-Operator – Multi Transmitter (One per band)

* QRP stations are limited to 5 Watts average (CW/RTTY/PSK) or PEP (SSB) at the transmitter output.

Each category will have High Scores for SSB, CW and Digital awards.

Any station in Single or Multi Op may win the Single Mode awards – BUT Multi ops will not be eligible for single op categories.

NOTE: The Mode scores are purely on the highest score and may be from a partial log. You do not enter SSB only – rather the log is determined as having the highest SSB score.

5. Permitted Bands

Contacts may be made on 160M 80M 40M in SSB, CW and Digital (PSK and RTTY Modes)

NB. PSK and RTTY are the only allowed digital modes and are combined, not counted separately.

6. Multi-operator Stations

A. Multi-operator single transmitter stations are only allowed one transmitted signal on air at any time.
If you are using three transceivers to scan the bands, simultaneous transmission will reclassify you as
Multi Transmitter(Category F.) – your responsibility to stop multiple transmitters operating.

B. Multi-operator Multi Transmitter stations
a. Are only allowed maximum one transmitted signal per band,
b. Simultaneous transmissions on different bands are permitted.
* Multi-operator stations are mixed mode only.

7. Contacts

A. Suggested Call: “CQ TT”, “CQ Contest”, or “CQ Test”

B. Exchange: A valid exchange consists of RS(T) followed by a three figure serial number starting at 001 for each band.

C. No cross band contacts are allowed.

D. Exchange of contact information via satellites, telephones, repeaters, Echolink, IRLP, or the internet is not in the spirit of the contest and is banned.

8. Scoring

All contacts are worth one point – Add the number of contacts made in the two hours and multiply by the different prefixes worked on each band in that two hours.

NB external territories count as one prefix – eg VK0 counts as VK0 and not the separate DXCC same as for VK9

e.g. 160 80 40 total contacts 50 X 35prefixes (total of each band added) = 1750 points per hour

Final Score is the addition of each two Hour 3 two hour blocks starting at 08:00

9. Logs

Logs are due in within one week of closure of the contest.

K6TU.NET adds support for generating Terrain Profiles

Posted by Trent, VK4TS

Woodside, California – January 21st 2015:


K6TU.NET adds support  for generating Terrain Profiles for use with ARRL HF Terrain Analysis tool


Stu K6TU’s propagation-as-a-service website at http://k6tu.net now provides you with the ability to generate a terrain profile for use with the ARRL HF Terrain Analysis (HFTA) tool.


Written by Dean Straw, N6BV, HFTA models the performance of horizontal antennas over the actual terrain surrounding the antenna and graphically displays the results.  HF antennas are impacted by terrain due to reflection and diffraction effects in the near field which can significantly enhance or degrade antenna performance.  Modeling these effects allows optimum antenna placement and selection of height above ground.


To support this modeling, the user must first obtain a terrain profile which describes the height of terrain around the antenna location.


Before Stu’s addition to K6TU.NET, the user had to obtain digital elevation data for their location and then use a GIS tool like MicroDEM to generate the profile.  This process is cumbersome and time consuming as the source of the data must be located, downloaded and then processed with MicroDEM before HFTA could be used.


With K6TU.NET you simply login to the site and fill in a Terrain Profile Request describing the location of the antenna in latitude and longitude.  Clicking on the “Generate Profile” button causes the request to be processed by the site in the background usually within 2 to 3 minutes.  The site sends you an email when the Terrain Profile Request is completed.


“The addition of this feature to K6TU.NET is superb!” says Trent Sampson VK4TS, going on to say “The process of getting terrain data was the bane of using HFTA and Stu has that nailed.  In a word, FANTASTIC”.


In addition to generating Terrain Profiles, Stu also has a utility he calls HFTASWEEP which uses HFTA to generate a detailed model of the antenna for use with K6TU.NET propagation predictions.  The combination of modeled antenna performance together with use of the effective-SSN (SSNe) enables “near cast” predictions to be made for contest and DX strategy planning.


Terrain Profile Requests are available to any user with a registered account on K6TU.NET at no charge.  A subscription to K6TU.NET is NOT necessary to obtain a Terrain Profile.  Stu’s site has copies of both the USGS National Elevation Dataset (for the United States) and the NASA Shuttle Radar Topography Mission dataset (Outside US with data for the world between latitude 60 South and 60 North) enabling fast turnaround of requests.

ARRL DX Contests 2015

Posted by Trent, VK4TS


Objective: To encourage W/VE stations to expand knowledge of DX propagation on the HF and MF bands, improve operating skills, and improve station capability by creating a competition in which DX stations may only contact W/VE stations.

W/VE amateurs work as many DX stations in as many DXCC entities as possible on the 160, 80, 40, 20, 15, and 10 meter bands.

DX stations work as many W/VE stations in as many of the 48 contiguous states and provinces as possible. Read more…

Ross Hull starts an exciting 2015 in Contesting Happy New Year

Posted by Trent, VK4TS

January 1 2015 and that means the Ross Hull Contest is underway – VHF UHF Contesting for a full month -

Entrants may operate on every contest day, but the final score is based on the best seven days nominated by the entrant.

For amateurs with limited operating time, there is also a “Best 2 Days” section. For many entrants, the two days of the Summer VHF-UHF Field Day will probably turn out to be the best two days in the month. You can import your Summer VHF-UHF Field Day contacts into your Ross Hull log.

Each contact scores one point for each 100 km of distance worked. This score is then multiplied by the band multiplier. The total score is the sum of the scores on all bands.


New Rules for Trans Tasman 2015

Posted by Trent, VK4TS

TT2015 has many rules changes.

There will be two contests that are identical – they will be held in May and July.

Both Contests will offer 160 80 40M Bands

There will be three Modes SSB CW and Digital. (RTTY or PSK)

There will be three power levels High (open) Medium (100 watt) and QRP (10 watts ).

There will be these power levels as categories for Single op and Multi Operator.

Categories will be :

Multi Op – High Low QRP

Single Op  High Low QRP

There will be no single mode or band category – We are trying to encourage all contesters to use multi modes/bands.

Repeat contacts will be allowed every  hour. You will be able to contact another station on SSB,CW and RTTY (PSK) every  hour on every band 160 80 40.

Multipliers will be in the shape of VK and ZL Prefixes eg ZL1-0 VK1-0 and ZM1-0 and VI1-0. (every hour)

All contacts will be worth 1 point. The multipliers will mean you will need to change bands to grab the extra multipliers.

These changes were bought about by the responses to the Survey of active competitors.
