# simpleSA
|
|
|
|
Simple Spectrum Analyser, based on 2 off SI4432 modules, an ADE25 mixer,
|
|
a programmable attenuator and some filters.
|
|
This version is intended for homebrew by those experienced in amateur radio or
|
|
similar techniques, or those wishing to explore these and learn the hard way!
|
|
No support is available for the code or the hardware.
|
|
|
|
|
|
The code was initially based on Arduino code for STM "Blue Pill" developed by
|
|
Erik PD0EK and ported to run on an ESP32 by Dave M0WID.
|
|
|
|
|
|
Subsequently the code has been extensively reorganised, modified and developed,
|
|
with much of the work done by John WA2FZW.
|
|
Additional features have been added, including the ability to view the
|
|
trace and change settings from web clients, and later additional modes
|
|
such as signal generator, IFSweep and the ability to control a tracking
|
|
generator.
|
|
|
|
Glenn VK3PE has developed some boards for this version - see his website.
|
|
|
|
Erik has since gone on to produce a commercial version called TinySA.
|
|
The commercial version has quite a lot of additional features, but does not
|
|
include the wifi features of this version, or the integrated tracking
|
|
generator.
