"What is the TDA2003 IC chip you used?"
you can use a TDA2002 or TDA2003 or
the

NTE1288 or NTE1232
It was a common car audio amplifier IC.
"I Like it, I'd like to see the VFO circuit used there."
this xmtr is cystal controlled, but I also had my VFO
driving it. the basic schematic is at the bottom of
the webpage. I added a voltage regulator.
But I came up with another VFO design I'll post,
after I re-build it. This VFO will hopefully be able to drive a
old tube xmtr.
