A pleasant trip north via "The Dish"

A friend had some boxes of yachting gear left in Melbourne and I kindly agreed to drive it up to him at Dorrigo NSW. Along the way I visited John, VK2ASU, Merv and Dallas, VK3EB. 

On the way back I dropped in a Parkes and took another look at the CSIRO Dish.

It was a long drive in the Jimny and to avoid the high noise level I listened to podcasts in noise cancelling headphones.

I stopped for two nights at Port Macquarie and was interested to note that a podcast I listened to later, which was obviously downloaded while I was there, had local Port Macquarie targeted ads inserted in-line.

The return trip was more rapid and the final run from Dubbo to Drummond was a marathon in hot conditions.

It was good to get away and to catch up with friends. It's good to be back.

Here's a circularly polarised log periodic antenna.

Here's an Apollo 11 S band OMT:

S Band is 2.4–2.483 GHz. I think an OMT is an Orthomode transducer which is a waveguide component referred to as a polarisation duplexer.

Here's an impressive bit of work, a C30 Converter:
