[Kenwood] TS-820S rear panel IF connection

Mon Nov 24 18:31:40 EST 2008

I doubt a frequency counter can read the frequency on the IF out unless you 
tuned in a real strong signal where there is a large carrier output to the 
IF out. A spectrum analyzer will show where it is. Since that is meant to be 
fed into the SM 220 and it will "see" a .5 uV signal you won't get anywhere 
near .5v from it unless again you had a very strong signal you were tuned 
to.
The raspy audio is a carrier oscillator adjustment.
