HADARC Repeater At Storey Park.

HADARC Repeaters

HADARC repeater hut at Storey Park:

Over the years, HADARC has lots to do with repeaters.

TODO add link to HADARC's repeater history webpage.

Storey Park Site

View from street of BBQ, hut and tower.

• Renovated in about 2019-2020
• Also, it's a good site to operate Friday 40m net from.

Community Centre Mural

Mural traces the histroy of the site.

Fowler's Pottery factory operated until 1947

RNS Hornsby talking to RHT Chatswood

VK2RNS taking to Chatswood or maybe Berowra.

HADARC has a strong association with the site.

Tower

• 70cm 'binary' array
• 70cm yagi (unused)

• 2m colinear pair at top is used by the repeater
• 2m lower is unused.

Hut

• VK2RNS 2m FM
• VK2RNS 70cm P25, DStar, potentially other modes in future.

Solar

• In 2023 VK2BAI secured government grant for solar power
• In 2024 system was installed
• has been running successfully since start of May

Components

1. Charge controller, Panel cut-off, Battery/Load Cut off

   

2. Batteries

   4x 100AH, ~12.5V LeFePO > 4800Wh

   

3. Breakers/Fuses

   Fuse on battery, breaker on load

   

4. Battery Current Shunt

   

5. Load low-battery-voltage cut off

Monitoring

• Am currently only monitoring charge controller.
• When battery shunt is installed, will be able to monitor battery and load currents as well.

• Average daily consumption: ~350Wh
• 4800Wh of batteries, use < 400Wh/day, ~12 days of nothing but pitch black

So, far there's been only one deficit day:

With extended P25 TX on the Tuesday

• Fancy graphs and pretty pictures to follow as time permits.
• have been running entirely from solar since 7th May, 2024
• Will disconnect 240V supply at end of August.

Repeaters

Radio Rack

• 70cm TX and RX Tait radios at top, 70cm RPI and
• 2m Tait repeater below.
• messy wiring is temporary

2m controller

• RPi on top
• controller below
• Wireless Router provides internet access

Inside the controller box:

Circuit. USB sound, 555 HW timeout timer

70cm controller

Is a MMDVM controller board similar to this, and attached to a RPi via the pin header.

Repeaters Block Diagram

Software:

• Allstarlink on 2m, allows EchoLink too.
• MMDVM something on 70cm, P25 and DStart, potentially others eg DMR, Fusion, whatever
• With some additional HW, would allow 70cm and 2m to be linked, eg during Monday net.
• VK2DIO can elaborate.
