VK4LC radio activity - April 2014
Band Antenna Power
80m dipole 400W
40m dipole 400W
20m 3el yagi 400W
10m 5el yagi 100W
2m 22el yagi 400W
70cm 44el yagi 200W
23cm 35el yagi 10W

I'm not into the modern DSP radios and prefer to use and work on the older solid state and hybrid sets. The main HF radio is currently a IC-751A on 80 through to 10m. A IC706 is running most of the time on 50.100 or 50.200 as well as IC-271H, IC-471H and IC-1271 for SSB on 2m, 70cm and 23cm.

The TS-820 line up doesn't get much use these days as I prefer to run it in winter when the shack needs warming up and I can turn on the TS-520 if it's really cold.

Other radios include Motorola Astro Spectra's for APCO25 on 2m & 70cm, IC-2820H and ID-880 on D-Star (what a boring mode that is) and some Yaesu FT-8800's for 2m and 70cm FM as well as a few Kenwood, Motorola and Tait radios for 2m, 70cm and listening to some of the commercial services.

Antennas include 3 elements on 20m & 15m, 5 elements on 10m, 22 elements on 2m, 44 elements on 70cm and 35 elements on 23cm. The 6m yagi is the next antenna to go up on tower number 2 with the HF tri-bander.

I have been doing a bit of work on SMD rigs for some friends and starting to become proficient with SMD soldering/rework including doing a CPU replacement on an IC706MK2G, but keeping the older discrete component radios running is more fun.

I work in ICT for past 25+ years covering PSTN, transmission systems, signaling systems, VoIP, LAN/WAN, backup power systems, network resiliency and many other facets of data and telecommunications as well as a bit of a dabble with C, Python and PHP programming.

Other interests include Raspberry Pi experimenting, PIC microchip design and programming, portable VHF/UHF operating, camping, four wheel driving, fishing and cooking up a storm in the Webber BBQ. I'm also in the process of erecting the 70cm VK4RPT APCO25 repeater in Brisbane using a Motorola Quantar which our wireless institute seems to not favor. We are really disadvantaged in VK with the current WIA board only seeking self gratification and not promoting the hobby properly whilst dumbing down our requirements to the point where some bands are just not worth visiting when some of our neurological inept operators are on.

Special thanks to my lovely wife for not complaining too much about the ever increasing amount of aluminum and steel that keeps rising from our QTH and the long hours I spend tucked away in the man cave working on various projects.

M2 antennas on 2m, 70cm and 23cm with Create RC5A-3 rotator and Comet GP-15 for 6/2/70 on top of 50ft crank up tower. All are fed via two lengths of LDF5-50 with Comet diplexors at either end to break out to their respective antennas.

If you want to have your say about the WIA and not get censored like so many groups will do to you, try joining the unofficial FB page of the Wireless Institute of Australia at�https://www.facebook.com/groups/wirelessinstituteofaustralia/ because they weren't smart enough to set one up first!
