Australian Amateur Radio Station
|S.T.a.R is an acronym for Software Transmitter and Receiver and was developed by Peter Rhodes
(G3XJP) several years ago. The original articles appeared in Radcom and were a full description of
building a HF multiband transceiver. I decided to tackle this project as soon as I had found out about it in
early 2009 and thanks to boards produced professionally by VK3PE (Glenn) and the enormous help from the
STaR community, I was able to complete my STaR transciever without too much fuss. Those interested in the
S.T.a.R. (also known as Pic-A-Star) are directed to do a google search on the topic. There is an abundance
of information and the best and first place to start is to look at the Picaproject forum on YAHOO.

It would also be a good idea to check out Glenn's website (VK3PE) at:
For those in VK, a builders' net is usually held every monday at 2000 EST on 3.6550 MHz.
|Having completed my 1st STaR, I was so impressed with it's performance that I built a 2nd. For STaR 2
I decided to incorporate the graphical display. I found the PCB method of construction very easy to
implement and whilst the aesthetics may not be as good as a professionally custom fabricated
enclosure made from Aluminum sheet, I am still reasonably happy and of more importance, the
functionality is 100%.
Below are some pictures of my 1st STaR transceiver build. As can be seen I opted for the "all-PCB
enclosure" method of fabrication. The mechanical construction was by far the most time consuming and
looking at what other builders did with their STaRs certainly gave me ideas on the most electrically and
mechanically suitable layout for my transceiver. I hope these pictures might help others.

and BPF assemblies.
