Anyone care to venture a guess what's inside this?

Put together a little rf speech processor last night on a bread board
using color burst crystals for IF filter and osc. Works great with 9db of
clipping, about $10 worth of parts off the shelf cost. Took about 2 hours
to bread board it up. I figure a one man production line could build one
in about 30 minutes.Its just stuffing a board and soldering.

Got a nasty cold so I stayed away from work today and tinkered with my
speech processor some. Replaced the transistor mic amp with an op amp and
Put an FET in seies with the input to the amp. Feeding the gate of the amp
with dc derived from the output of the processor giving it AGC. This thing
is getting to be a knob twisters delite. One thing did get me thinking. I
have a nice scope to look at the output of my TX and to lookat the output of
the processor , for me its a piece of cake to setup. How can you do this
without test equipment?
