Coax cable shield grounds and connectors through out the radio.

Grounds in module power plugs.

Your downspouts. Yes. downspouts and other loose metal stuff around your 
antenna and house.. bad connections cause rectification and birdies.. not 
too likely compared to the coax shields though.

Do you get these extra signals with the antenna disconnected/input 
shorted?  .. with the RF amp tube pulled out? (.. and so on down the tube 
lineup.)  Have you put a cover over the top of the radio to see if the 
signals get lower in strength?

I look forward to hearing what you discover is the trouble.
