Probably the lowest measured IMD distortion you can get
(see ARRL tests)

QSK
In use here for several years to run West Coast Swap Net on 40M.

I renewed the power supply caps with 5000 hour rated 105C units
( typical life for many types is only 2k hours).
Only reason to sell is a need for money!
I typically run this at 1Kw PEP output... in which service it is rated to run key down continuously any mode 24/7 !
First class engineering and construction.
No cobby crap under pretty paint here.
