[TenTec] Century 22

[Bob, WB2VUF]

Hi, Josh,

Congratulations!  The Century 22 is a very nice rig.  I bought one used 
some years ago.  They are quite rare, but get very good ratings.  It's a 
good rig for casual operating and nets. It isn't so good for contests on 
a crowded band because being direct conversion, you get QRM from both 
sides of zero beat.  However, the audio filter is excellent.

A word of caution:  It is important to use the original power supply and 
to make sure that the current limit is set correctly, or use a 
fast-acting 5 Amp circuit breaker in the 13.8 V line. The C-22 has no 
internal SWR protection, so without current limiting or a breaker, a few 
dits transmitted into the wrong antenna will destroy the finals 
instantly.  I learned this the hard way.

I have  a scan of the manual which I will send you.  It's a little 
better quality than the Ten Tec scan.  I got it off the G3YCC web site. 
My copy has some typed notes from G3VTT on the table of contents page 
regarding bias settings and final replacement.  Ten Tec replaced the 
original MRF-475 finals and MRF-476 drivers with the 2SC1969, which are 
more robust.  Genuine Mitsubishi 2SC1969s are available from RF Parts 
Co.   Beware of  on-line sellers who market counterfeit 2SC1969s for the 
CB market.

73,

Bob WB2VUF
