Remember, I am an old fart.
The ts480 is a wonderful radio!!!!
I don't like internal tuners, because the antenna has to be relatively close 
to resonence.  They will extend the usable range of a resonnent antenna. 
They are not very efficient because of their small size.
You youngsters seem to like no tuning no knobs to adjust, etc.  You are 
probably right about that.  I just preffer my old mfj 989 which has a roller 
inductor, and will handle a killowatt.  Remember, I still use my Johnson 
Valiant, which has to be tuned both at the drive and final output sections. 
What's a "pi network"?  You don't get anything above 6 meters with the 480, 
but from there on down, it's a great radio.
I have been trying unsuccessfully to get my d-104 to work on it.  The j-38 
naturally works fine!
