check the OT contest sponsored by the Antique Wireless Association
usually Hartleys or TPTG rigs what a fantastic contest
it is an honor to get a chirp report from a O O
80 and 40 meters 

I have a hartley which can chirp out of the passband of a modern rcv
depends on how much power I try to get out of it
