pi2wf needs .net Framework 3.5 ver 1.0 9ED90150

This takes image (.bmp or .jpg or .gif) and coverts to .wav that can be viewed as radiogramme on radio waterfall.
Images can be loaded from file or drag+drop or pasted. Easiest to create image in paint, then chose rectangular
section to copy, than paste onto pic2wf picturebox. Image should be 280px wide.

The attached CQCQe.wav shows outline font that unfortunately doesn't include numerics, notice that when viewed
that the middle line is brightest since fewer pixels per line. pic2wf allows for audio to be processed for maybe
1 "S" point improvement. Also, the 'economy' setting transmits fewer pixels for improved picture display.

But still 100Watts of transmitted power is spread over about 1kHz of spectrum, so this might be a QRP transmission
scheme.


nSpecaz needs .net Framework 3.5 ver 1.0 BC131BC6

This plots audio as either vertical or horizontal waterfall. The program is intended to be easy to use.

It uses cscore WASAPI loopback so it plots whatever is playing on default playback device (loudspeakers).
I don't think XP supports WASAPI. 
nSpecaz has been tested with 44.1k soundcard but may work on 96k and 48k soundcards too.
Sometimes on program exit a debug message is shown...

Right click on spectrum display to select palette. 
This is a full trust .net program

Creating a shortcut with command line argument 
line
may allow read from line input although no sidetone audio.

Creating a shortcut with command line argument 
-2
will try to use 2nd device if available

.wav "Open with" nSpecaz might work too

both these programs work fine on my 20 year old windows7
