Re: What's on your Workbench?

75% complete repackaged 6cm transverter now with a 10W PA stage and a sequencd DB6NT preamp at the feedhorn.

Hoping this thing may help set some more VK4 records this coming Winter.

VK4RTT 6 and 2 metre off air

Gidday,

The beacons on test at Mt Cootha have been removed for diagnosis. They became somewhat broad, we suspect a locking issue with the ZL PLL.

We’ll keep the community apprised of any developments.

Re: Brisbane beacon summary

Thanks Rex, good to hear from you.

We are working on getting an A/C installed to better manage the temps in the room.

Largely yes, changed our mind and will be implementing a 91.5 Hz CTCSS shortly, suggest operators update their radios now.

Re: Mt Mobilin Beacon VK4

Good plans going awry again, VK4RTT will not be installed this weekend. Hopefully it will be going on the FD weekend, I will try and combine the install effort with a bit of portable operating from Mt Cootha.

Re: 2019 Spring VHF-UHF Field-Day Contest

Trying a home station (QG62mo) this time given I get some antennas up. Will be trying 10, 24 and 47 GHz from the roof if there is sufficient interest and the weather is kind.
