Workshop/Technical

PARG holds a Workshop/Technical night on the third Tuesday of the month. Of recent times we have had to hold these meetings over Zoom.
This has allowed members who are restricted by distance to join in and indeed contribute to the education (and sometimes amusement) of all members in things associated with RF.

We hope to include many more presentations to this page, in the future. Please come back to check what's new.

The first presentation was done by Mark VK2KI / VK6QI who lives on the other side of the country. 

As they say in the classics 'sit back, relax and enjoy!'

How do repeaters work?
https://youtu.be/qbste97e5yk
Peel Amateur Radio Group TechTalk by Mark Bosma VK6QI/VK2KI and Martin Diggens VK6MJ on the operation of repeaters.
The video is quite long (102 minutes - a bit like a boring movie!) but covers:

- how amateur radio repeaters work,

- the technical challenges,

- operating advice, and

- concludes with a visit to the VK6RMH 2m repeater in Mandurah, and the usual closing credits.

The video could be of interest particularly to Foundation and Standard amateur radio license holders, or people working toward their first license.



Portable Amateur Radio Operations
https://youtu.be/e1_Zh5kwsA0
Peel Amateur Radio Group TechTalk by Geoff Hart-Davies VK6GHD on portable amateur radio operations.
Geoff’s terrific talk on portable amateur radio operations, includes:
- Summits on the Air, World-Wide Flora and Fauna/VK Flora and Fauna, Islands on the Air, and
- Beaches on the Air, - websites, - equipment - antennas. 
The talk is followed with a short discussion by Maurice Bersan on his interesting Microbitx all band HF transceiver kit that he uses portable.
The group then looked at a very nice Yaesu FT101Z and Geoff's Yaesu FT-817 to see whether he'd let the smoke out of the final transistors again.
The usual (hopefully) humorous final credits round out the video.
