Above is my 5W simplex crossband repeater on 146.575 and 438.900MHz. It is the equipment up the top of the radio rack. 2 x PRM80's (fan cooled) with a home brew crossband cable connecting the two radios via the D15 socket at the rear of the radios.

These give me about a 15Km radius coverage which easily covers the township of Orange

The middle unit in the radio rack is a normal 70cm repeater with a TX filter underneath. It is there if the local club repeater on the mountain goes down so we still have coverage around town. It is only switched on when needed. Otherwise it is switched off.

The bottom unit in the rack is the power supply. It was a Philips TX814 repeater TX unit which had been ratted, but the power supply was still intact. So I continuned to remove the remaining obsolete TX parts and modified it as a sole power supply. Added indicator LEDs at the front and banana sockets.

All is battery backed for continuous use. The system as of Oct 2013 is now 100% solar. I have 100w of solar panels on the roof. I have 50W facing north, 30W facing west and 20W facing east. This is so I can make maximum use of the sun and have charging over a longer period of time during the day. The power supply is now only there for a back-up or if we get a lot of cloudy days in winter.

The panels run into about 120Ah of batteries via a regulator. This easily runs the cross-band repeater, lighting over my workbench and a old car stereo.

These are my northerly and eastern panels.

These are my western facing panels. They are wired in parallel, so if one gets a shadow on it, it doesn't effect the other.

 

Here was my attempt at the VK 2017 Summer VHF/UHF field day in Jan 2017 with my son to help me set-up and observe.  I was running only 6m and 2m and got 26 contacts over 4 hours. This is an abandoned radio site as the owners left it because of the vandalism, surprise, surprise. As you can now see, all the is left is the compound fence and the antenna mast. This was fully intact 7 years ago. The height of the site is 1250m, and has a great takeoff for most of it.

Here is the same contest radio site in snow in winter. This was the day after snow fell and as you can see there was still plenty left.

Notice the ice build up on the wire.

John Moyle 2016

This is me doing the VK John Moyle Field Day Contest in March 2016. I was doing it solo and only doing HF.

I had a tri-band (40/20/15m) resonant 1/2 wave diapole and 10m "stationmaster" vertical antenna which are to the right of picture and can't be seen. Radio was my little FT-817 with a 50W linear.

 

 

This is my current setup. I made this radio console as a project at school, 30 years ago !!! It was much different back then, only one radio and it had a front on it, as you can see below. Once I got more radios, the front went.

 

original

This is the original console (circa 1980s). The only things that I still have from here is the CRO and the yellow storage drawers.

 

Hope to catch you around the bands or on echolink.

Cheers,

Doug VK2XLJ (Xtra Long Johns)
