[TenTec] TT 238C will not tune

[Bob McGraw - K4TAX]

Correct Jim, the cord can be installed such that either way could be maximum 
inductance.  In general I find that #30 is, or at least should be in my 
thinking, maximum inductance.

Having had my tuner for some years, the cord has long deteriorated.  Maybe 
one day I'll get around to replacing it.  In the mean time,  I did make a 
chart for each antenna and each band and with several frequencies noted. 
Today I just set the C for the value on the chart, set the BYPASS switch for 
the value on the chart and crank the L for the lowest SWR.  It really 
doesn't get much faster than that.  Also a very important note, my switching 
arrangement does allow me to use my analyzer to set the value.  I do not 
transmit while making adjustments.  We have enough QRM on the bands without 
some bozo generating carrier to make tuning adjustments.

yeah…just found that out! should of caught that sooner…..
I had a 238C demo that TT sent me some time back and for the life of me 
could not remember the dial numbers being reversed.
