Ten Tec Titan II QSK Legal Limit 160-10: Probably the lowest measured IMD distortion you can get
(see ARRL tests)
160-10 Meters
Legal Limit Plus
Grid Driven 40x power gain
25W in = 1000 W out
QSK
In use here for several years to run West Coast Swap Net on 40M.
Runs Cool and Quiets in heavy traffic handling environment.
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.
