RadioScope - HF Propogation Study Through Multiple Sites

Welcome All interested in the further study of HF propagation

This new website is to generate interest in the extension of recent studies of backscatter radar and propagation on 50 Mhz by VK3OE and VK3AUU into the HF realm..

How could it work ?

The proposed concept is to create an aggregation of amateur radio stations around Australia to study the effects of propagation over the LF and HF spectrum; through a nationwide grid system of stations linked via broadband internet for real time analysis...

The proposed stations:

• will have remote rural locations for low interference reception
• exhibit high gain antennas for a variety of bands
• have broadband internet access for real time information aggregation
• ability to operate high power if needed for the conducting of tests

MEMBERSHIP IS OPEN TO ANY INTERESTED IN PROPAGATION

My SteppIR BigIR No Longer For Sale

I was considering selling my SteppIR BigIR MKIII with 80m loading coil. I put a few feelers out there but have now decided to keep it. There was a bit of interest as they are great antennas.

I had it pulled down but have now done some maintenance and she is back in the air. I still need to wire it up and lay the radials again. This time the install looks much tidier and I won't be getting grass and weeds growing up through the radial plate.

Inverted V for 20M

My brother Steve VK4VSP came over today to pick up the Icom IC-706MKIIG. Steve is a full time student and has to attend residential school a couple of times a year. He has made up an excellent portable station of which I am hoping that he will blog about it shortly. He intends to take the gear with him on his trips to Armidale, NSW.

We had a look around the shack to see if we could make one up from my bits and pieces. The end result is an Inverted V which is resonant at 14.175MHz. The pole is not mine and I have ordered a 7m heavy duty one from Haverford.

Cubex Quad Freight Charges

I've just received the freight charges from Cubex to deliver a Cubex Quad MKII (3 band) to my door. I'm afraid that the costs have completely put me off. Essentially, door to door the charges are more than the cost of the antenna itself.

Time to look for an Australian sourced antenna.

Tower - Town Planning

I called the Logan City Council again yesterday to clarify a few things. There is some confusion with regards to the maximum height of a mast before approval is required.

As I live in the old Beaudesert Shire Council, I fall under the Beaudesert Building Code which has a maximum height of 8.5m before approval is required. For others living in the Logan City Council, the maximum height is 10m.

I am considering only putting up 3 sections of the mast to begin with (7.5m) and then eventually get around to applying through council to extend the height. From what I gathered from the conversation yesterday, Logan City Council later this year may bring all building codes into line.

What I have learned so far;

• Do not refer to the tower as a tower, it is a mast.
• I will need a building certifier, no matter what
• Max height is 8.5m before I need approval
• Must be erected within the building envelope
• My property is zoned as Rural Residential B

Thanks to the following for their input so far;

VK4TI, VK4KKD, VK4JD, VK4FEAT, VK7ZE

Tony Spies VK4HO has a great website showing the process (with pics) of installing a One Man Tower.

Any building certifiers in the area who are hams, I would love to hear from you.

Tower and Department of Infrastructure and Planning

Thanks Trent VK4TI for sharing this info.

Qplan is Queensland’s new planning, development and building system. As stated in this document I gathered the following information;

This fact sheet outlines when development in a residential zone does not require a development permit for a material change of use.

A material change of use of premises for certain buildings and structures, defined in the Building Code of Australia, is now prescribed in schedule 4 of SPR as being exempt from assessment against a planning scheme in certain circumstances. This means that development permits from local governments will no longer be required for these types of development.

Building classifications that will now be exempt are:

Class 1(a)(i)—detached houses;

Class 1(a)(ii)—attached dwellings, comprising of no more than two dwellings (for example,duplexes); and

Class 10—non-habitable buildings or structures such as a private garage, carport, shed, fence, mast, antenna, retaining or free standing wall, swimming pool or the like.

More to follow as I find more info.

More on the Tower Situation

I've had a bit of a read on the Logan City Council website and found the following;

Approval may not be required for certain buildings/structures if they are considered self-assessable building work.

Building work-self assessable:

Building work is deemed to be self assessable where:

The building work is for a Class 10 building or structure, and:

Part e)

It is a non-load bearing aerial, antennae, satellite dish with a maximum diameter of 600mm, flagpole, mast or tower, outside areas covered by airport Obstacle Limitation Surfaces Standards (OLS) of the Civil Aviation Safety Authority and it is:

a) detached from a building or structure and not more than 10 metres above natural ground surface;

More to follow as I find more information.

Seeking Tower Approval

Oh, the fun begins. I sent an email to the Logan City Council on Monday asking some questions with regards to erecting a tower on my property. I got a phone call from one of the town planners today.

Essentially, if the tower is 8.5m or less, I do not need to gain approval from council. (8.5m or double storey). If the tower is greater than 8.5m, which mine is, then the fun begins.

Why does it always seem that when it comes to an amateur radio tower (hobby, for personal use), no one at council really knows how to deal with it. I'm sure if I speak to someone else next time, I will get a different answer.

Ok, so what do I need to provide? This is what I was told to complete;

• Material Change of Use form (MCU)
• SPA 1, 5 and Checklist
• Site Plan
• Elevation Plan (pictures, etc)

I asked about costs and was told $700. After I picked myself off the floor, I questioned the cost and said that others have paid nowhere near that price. I was told that possibly others have applied for a Class 10B Structure (Ancillary to the House) which costs $250. I was also told that because I live in the old Beaudesert Shire Council, that rules are slightly different to those of the Logan City Council of which I am now part of.

See the problems I am having here. Maybe I should just put up 3 sections of the tower (7.5m) and not seek approval. However, I still need to know where my building envelope is.

If anyone lives in the Logan City Council area and could provide some advice it would be greatly appreciated. If you live in the old Beaudesert Shire Council then that's even better.

VK4HAM New Website

If you have been a follower of Andrew's VK4HAM blog, Ham Radio & Bloke's Stuff, you will realise that the blog has been discontinued. However, even better, Andrew has created a new website called VK4HAM - Your Home for Contests, DXpeditions and More.

The new website can be found here. I highly recommend you take a look, become a member, uploads photos and videos, or join the forum.

VK4VCC as at 6 Feb 2010

Again, very quiet from me but hopefully that will change over the next month. I am currently "downsizing" the shack. I had too much clutter in the shack and half of it I wasn't using. I was trying to create a SO2R type station but have now decided to keep it simple.

I have either sold or still selling the following items;

Yaesu FT-920

SteppIR BigIR with 80m loading coil

Array Solutions PowerMaster

Top Ten Band Decoders

Top Ten DX Doubler

Dunestar Auto BandPass Filters

All I plan on keeping is the Yaesu FT-950, one of the Array Solutions PowerMasters, power supplies, OzSpid rotator and tower. Chelsea and my main focus will be on the higher HF bands (20-10).

I'm looking at getting a Cubex Quad MkII (3 band) shipped in from the US. I've sent the email off to see what shipping costs will be.

Steve VK4VSP, my brother, will be borrowing the Icom IC-706MKIIG with all the accessories.

I'll be getting a quote shortly from the concretors so I can get the tower up. It will be great if I can get everything sorted for the CQ WPX contest.

ContestRank

Welcome to ContestRank.com! The site was developed with a desire to acknowledge the participation and achievements of all contesters, worldwide, while providing a source of contest and contest-related information.

As we began developing this web site, we thought about how to best present contest result data in a way that would result in a meaningful contest ranking system. The number of contests each year and complexity of tracking and recording contest data presented us with a challenge. Ultimately, we elected to concentrate on results from worldwide contests that do not impose restrictions on participation, such as the CQ World Wide DX Contests and ARRL DX contests, and not include more regional or continental contests such as the European HF contest. Inclusion of these more regionalized contests would make it difficult for direct comparisons between contesters in other parts of the world who would not likely actively participate. Further, because of the number of contests each year – our current count is 71 – we had to limit inclusion to those contests that generate a high number of entries. We also knew that the site should be accessible in several languages to appeal to as many members of the global contest community.

In order to develop an effective rating model, we began collecting primary data such as final score, number of QSOs and number of major contests for each higher scoring operator/call sign, beginning with the 2000 contests. The development of our ranking model is a ongoing process and will be refined over time. Our team is planning on honoring the top contesters each year based on the final scores, the number of QSOs and number of contests entered.

We are also designing this web site as a meeting place for contesters worldwide, so we can get to know each other, share information about our stations, and make new friends. We also plan to develop related contest information pages covering equipment, amplifiers, antennas, and software, with information submitted by the contest community. We would welcome your comments and suggestions as the site develops. Please tell us what you think.

“Good Luck in the contest…”

Very 73,

The ContestRank.com Team
