Winlink Project

Winlink hut coming together

Site preparations well under way

Toyota loaded to the gills with gravel, about 1.5t. Decided to put 100kg of concrete powder on bonnet to help hold front wheels down for traversing steep road

Mick up and running building a new piece of road to negate the existing steep sections on the access road

The crew digging the foundation holes. From left, Les VK4FLES on shovel, Chris VK4FGKO also on shovel, Bob VK4FRC on the water tank hose, Ray VK4XXX on the Dingo digger, arguing with the tough digging work. Ground is harder than concrete!

When the digging gets tough, add more weight 🙂 from left, Mick VK4NHX, Trevor Bell, Chris VK4FGKO and Ray VK4XXX

Mixing starts, from left is Les VK4FLES (our resident concreter) and Chris VK4FGKO on shovel!

Hardware under test.

VK4LM Winlink node is online. Not at its final install site as yet. It has been relocated to Weasel Park for final testing. Plus the current heat has placed the winlink site ground works on hold:( System is scanning dial frequencies 3571 7041 10141 14081 modes Ardop Pactor VARA HF and Winmore with a IC7200 connected to a Bushcomm BBA 100CS antenna. FT8800 on 144.075FM mode VARA FM on a home brew 3E horizontally polarized yagi. The PC stick has been getting a work out with concurrent connections on Pactor  HF and VARA FM VHF with out a problem. We have been getting connections from ZL2 ZL4 VK1 VK2 VK3 VK4 VK5 JA K7 SA6 as well as our local test team VK4JRC and VK4FLR on most bands and modes with good reports. Jack has been giving 160M a work out mobile also with great results. Been able to maintain connections mobile on Mt Morgan range as well as Mt Morgan CBD. Capricorn Highway Burnett Highway and Gracemere CBD also work fine. Rockhampton CBD noise floor is a bit much. Watch this space for more mobile and field deployment testing.

The system will fill a big hole in the coverage of VKs East coast and the Pacific Ocean. It is a hybrid gateway so if the internet is down emails will be forwarded via HF radio to a node with internet it will then forward emails to the CMS.

 Quick demo of Winlink and Pactor. 2574Km on 10W

System has had real world testing and it passed! 4186Km north east of us. Emails collected and sent via Pactor 3.
