Bear, that FET follower is starting to sound interesting to me.

Zero dollars, unless you count some patch cables.

Computer + freeware = FFT tester of significant capabilities
Computer + freeware = audio signal generator of significant capabilities

All you need to check the audio on ur transmitter is right there.

Got a 'scope? even easier...
No scope?
Time to get one!
They're pretty darn cheap these days for any post 1975 Tektronix... you want a 100Mhz scope or better, then ur ok.
Can't be a ham on AM without a scope...  Wink

<SNIP!>

Build one of the FET followers for the D104 and you'll have less to think about.

Cool.  It could also be done on perfboard, saving on screwing with etching a circuit board.

Build it dead bug style then mix up some 2 part epoxy and dip it in.
