I'm also using a small audio amp and speaker for

I use an Island Keyer II and can't say enough good things about it.
Mine uses only the speed pot and I power it with 2 penlight batteries which last over a year even tho I never turn it off.
I do no extra RF filtering or suppression as and I operate running 800 watts sometimes.
Great project - works great.
Good luck - 73
