Roleystone Working Bee – 18th Feb 2012

Another productive ~5hr working bee at Roleystone on Feb 18th. Tasks carried out were:

New Cavities swept, tuned and tested on 146.700
Old Cavities swept and tuned (then returned to service – new ones will now go to Tic Hill)
Foliage under Guy Wires removed
Foliage around Shacks removed
Foliage around HF Beacon Antenna removed
Foliage along driveway removed
Mute levels adjusted
re terminated 23cm coax connector
took measurements in preparation for cable tray between mast and shack.
Took several photos
Consumed Coffee
Consumed Muffins
Consumed Smartie Choc Chip Cookies
Suffered many prickles/thorns/splinters from bushes.

Thanks to those who gave signal reports at the time. We’d appreciate if everyone could give an indication of access coverage since the changes.

Sweep plots were captured and will either get published on the WARG website or emailed out on this list. (please contact me if you would like me to send you a copy directly)

We will require another working bee at some stage in the near future to:

Install cable tray
recover coax/ethernet cables from Mast
Possibly swap main antenna (pending changes to coverage reports)
Commission 3rd run of LDF5-50 (already installed)
remove foliage around perimeter/fire break
Level checks on audio interfaces (repeaters and news link)
Sweep DSTAR 2m Cavities
General tidy up of cable routing within shack
Possibly recommission VK6BBR
Document cables/connectors/interfaces for all equipment (for site database)

Many Thanks to VK6TWO, VK6FMON, Bruno, VK6AIF, VK6ZRW, VK6DB, VK6AXB, VK6LV, VK6JAH, VK6ZMS

Roleystone – Q1 2012 Working Bee

The Roleystone Repeater site requires another Working Bee to do a bit of a tidy up and make some improvements to the installation.

With the installation of 3 new LDF5-50 up the 80m mast, the old rigid line needs to be removed and sold/disposed of.

Cable tray is required to tidy up the coax runs between the Radio Shack and the Tower. Ray VK6ZRW is looking into a source for materials.

After a prolonged ‘Mains Failure” around August 2011, two spare 80W Solar Panels were placed flat on the roof and connected to the main batteries by Heath VK6TWO. These will have to be mounted in a more robust and efficient way. Some redesign of the DC power/Batteries would also be worthwhile.

Warradarge – New site for coverage to Geraldton

In November, Martin VK6ZMS, Heath VK6TWO and Monique VK6FMON traveled to a potential new site in Warradarge to assess the suitability for extending 2m Voice and APRS coverage up to Geraldton.

Warradarge is aproximately 260km north of Perth along the Brand Highway, and about 180km NLOS SSE of Geraldton.

A 10m mast was raised to enable some propagation/coverage testing from the 290m HASL Warradarge Hill.

The VK6RPT  2m APRS Digipeater was installed, along with 4.5dB antenna, deep cycle battery and 80W solar.

APRS packets from Warradarge have been received by VK6RCT, VK6RTH, VK6REX and VK6RAV.

Performance from the site has been much less than expected so a higher gain antenna will replace the current one to better assess the site for suitability.

Great thanks goes to Craig VK6FLAM who did a lot of the prep-work for this trip, but unfortunately had a last minute emergency which stopped him from attending.

It’s expected that 2012 should see permanent APRS and 2m Voice in this area, enabling coverage from Geraldton through to Cateby.

WARG Shop – LDF4-50 and LDF5-50 DIN connectors for sale – CHEAP

We currently have a very large supply of NEW DIN connectors suitable for LDF4-50 and LDF5-50 Coax.

We are looking for a Commercial / Bulk purchaser who may be interested in purchasing these connectors.

DIN connectors are used for high power coax connections in many commercial installations such as Telstra/Optus/Vodaphone base station sites, FM and TV broadcast sites etc.

All connectors are NEW, sealed in individual plastic bags, with instructions and individual boxes.

We also have many NEW mast/tower feedline securing brackets to suit LDF4-50, LDF5-50, LDF6-50, LDF7-50.

Lengths of LDF4-50 may also be available for purchase.

If you know of a company or individual who may be interested in purchasing some or all of these connectors, please get in contact with us for a list of model numbers and quantities.

Thanks to Bob VK6KW and Heath VK6TWO for the aquisition.

Fundraising – WARG Chocolate Drive

WARG are continuing to run the fundraiser chocolate drive in 2012 to help fund many of the ongoing WARG projects.

If you think that you can sell some chocolates to raise some funds for WARG, or would like to purchase them for yourself, please contact the Treasurer – Monique VK6FMON.

Thanks to Monique VK6FMON.

Cataby VK6RCT Working Bee – APRS

December 2011 saw a working bee at the Cataby repeater site.

Party consisted of Craig VK6FLAM, Graham VK6LV, Heath VK6TWO and Monique VK6FMON.

Activities consisted of:

APRS installation – Antenna/Coax/TNC/25W Radio/Lightning protection

2m Voice – Cavity Sweep/tune, Lightning protection, 5w handheld into antenna to reach VK6RAP.

Batteries – voltage/charge monitoring

Mast – Inspection

The Batteries were identified as requiring replacement. APRS voltage beacons indicate that overnight the voltage is reaching as low as 12v, then rising during sunlight hours.

Foliage in the area has increased significantly since the last visit so some fire prevention maintenance may be required.

VK6RAV – Hoddy’s Well (Avon Valley) – 2m + APRS

Hoddy’s Well, ~100km East of Perth now has APRS and 2m FM Voice repeaters.

Coverage ranges from Perth to the East right through to Kellerberrin.

Voice Repeater consists of the old VK6RAV from Northam.

APRS equipment consists of an Argent Data OT2 Digipeater coupled to a 25W radio.

The VK6RAV 2m Voice repeater can be accessed on 147.275+

APRS on 145.175

Both services were fully operational as of Aug 2011

Many thanks to Jim VK6CA, Craig VK6FLAM, Rob VK6UFO, Heath VK6TWO, Martin VK6ZMS, Monique VK6FMON.

Kellerberrin VK6RKN – On-Air!

Kellerberrin, ~200km East of Perth now has APRS and 2m FM Voice repeaters.

Coverage is approximately a 50km+ radius, from Cunderdin to the West, through to the East of Meerredin.

Voice Repeater consists of two PRM80 25W radios controlled by an NHRC repeater controller.

APRS equipment consists of an Argent Data OT2 Digipeater coupled to a 25W radio.

The VK6RKN 2m Voice repeater can be accessed on 147.325+

Many thanks to Bruce VK6LAW, Craig VK6FLAM, Peter VK6FUN, Heath VK6TWO, Martin VK6ZMS, Monique VK6FMON.

WARG Practical – Cavity Modification and Consolidation

The long weekend in March will be a WARG Practical – Cavity Modification and Consolidation day. All are invited to get involved with commercial cavity modification for use on 2m repeaters. Please bring along any drills, holesaws and basic tools you may have. Learn a thing or two about cavitiy filters and how to modify them for AR use. Time permitting, some of the older existing WARG cavities will be inspected/tested/tuned for future works.
