VK2IO is an amateur radio station 25km NW of the city of Sydney, NSW, Australia. Locator is QF56LG.
First licenced in 1976 as a Novice (now called Standard licence), I progressed to the Advanced licence in the following year and held the callsign VK2DAA. During a stint in England I held the callsign G0ODA and ran the GB7DAA packet BBS from 1990 for 2 years. In 1999, to reflect my interest in digital modes, I switched to the current callsign, IO being a common abbreviation for Input/Output in connection with digital data streams. In 2014, my G0ODA callsign was reacquired.

For the latest information on my recent activities check out my blog.
​My home station logbook is online here. Portable station log here.

VK2IO currently runs the following services:

  • EchoLink node 2509
  • HF APRS IGate
  • HF packet BBS/node/digipeater
  • VHF packet BBS/node/digipeater

EchoLink node

Node 2509 is a duplex node connected to a scanner running on 2m FM. It scans all the repeaters and some simplex channels. The scanner halts while there is a signal on the channel and continues after a 5 second break. The node transmits whenever audio is present. To prevent lockups, only home stations can connect to the node, not repeaters. You can transmit to the node if you want, but the audio wont go anywhere. There is no transmitter connected. Please feel free to connect to the node as long as you want - some hams stay connected for hours "reading the mail". Note that QRM can occasionally be experienced from co-located systems - especially 2m packet. The coverage includes all 2m repeaters in Sydney, Gosford, Wyong, Blue Mountains and Wollongong.


The APRS IGate operates on 40m, 30m and 20m using the BPQ software under the VK2IO-4 callsign. The 300 baud FSK AX.25 packets are demodulated using the excellent UZ7HO soundmodem software. Multiple close-spaced modems are used on 10147.6 to provide frequency agility of +/- 60 Hz and on14103 to provide +/- 40 Hz. The dial frequencies for standard 1600/1800 Hz tones are:

HF packet BBS/node/digipeater

An AX.25 packet system running under MS Windows is available on the HF frequencies above. Preferred frequencies to avoid APRS traffic are: 7047.17, 10148, 14105. The applications and callsigns used are:

  • VK2IO-0: BPQ packet mailbox

In Nov 2013 I got started in Summits On The Air. I'm now addicted to chasing and also do some activating. In 2014 I started a blog mainly to document my SOTA activities, but also for the projects I'm working on. Check out the blog here.


I have made some amateur radio-related videos and they can be seen on my GerardVK2IO YouTube channel.
