Well if you are a ham you will know what the following is about, if not, you won't. However, kitties don't particularly like the pure tones…..
I created 41 wav files for those of you who might want to use an older VHF/UHF radio with the modern repeaters or those who wish to annoy their kittehs. Put on your PC or MP3 player. Much cheaper than a tone encoder. 10 minutes long. They are on my home webpage.
