Re: Antuino - the antenna analyzer


This could easily be turned into a simple SA.  I’ll bet Kees already has the boards mocked up…

Subject: [BITX20] Antuino - the antenna analyzer




while trying to measure the swr on the cubesats, i figured i couldnt use any of the analyzers i had access to. they were simply too big to be stuffed inside a 10 cm cube. my simple resistive bridge was too insensitive for any reasonable work. so, i sat down and made an antenna analyzer from a spare raduino. 


the code is wobbly and just about enough to get my work done. it works on a superhet principle. this is not my clever idea, rahul had mentioned this approach taken by a russian builder. i havent seen the original design. it would be interesting if rahul or someone can point me in the right direction.


the code and a pdf of the circuit is on i am attaching the circuit for the lazy bones.


have a great holiday and get some dx !!
