[Kenwood] Kenwood TS-850S / Kantronics KAM Plus

Dick,
	I assume your talking about audio adjustments for running AFSK? Do 
yourself a favor. Use the FSK mode. The only drawback to FSK is that you 
have to go into a setup menu on the 850 to change shift. Since most of the 
digital modes associated with the KAM use 170 Hz shift, that's no big deal. 
 I ran my 850 with a KAM using FSK and it worked very well.
	That rear panel audio input on the 850 was prone to picking up RF. 
 Kenwood came out with a mod that changed a few resistors, and lowered the 
sensitivity of the input a bit. I made the mod - can't say that it helped 
much.
	I did have that rear input connected to my computer, and I did use it for 
SSTV and for playing sound files via the 850. I isolated the connection 
between the computer with an interstage transformer which eliminated all of 
the RF and other oddball problems. Most any transformer will work. The 
point was to break the ground connection between the computer and the 850.
	Check the June 96 issue of QST, page 71. It describes how I interfaced 
the 850 to my computer.

I have the Kenwood TS-850S and the KAM Plus.
Can anybody tell me how to make the adjustments for VR18 in the Kenwood
in relation to R28/K9 in the KAM Plus?
I presently have K9 in the low position and R28 about midway and the VR18
in Kenwood is shut down.
My signal is getting out OK but there is some distortion on it at the
receiving end.
Thanks
Have a Good Day,
