I recently got laid-off so I am selling off some of my equipment, I am selling my LP-PAN (for kenwood) and EMU 0202 sound card as a package deal Mon, 08 Feb 2010 22:41:27 GMT Bob AD5VJ http://groups.yahoo.com/group/TS-850_450_690/message/8884 http://groups.yahoo.com/group/TS-850_450_690/message/8884 Ok that is a relief, a guy is talking to me presently about owning his 'TS-850 like new' radio and I started some research on the model since most of my Mon, 08 Feb 2010 20:38:38 GMT Dave ve3wej http://groups.yahoo.com/group/TS-850_450_690/message/8883 http://groups.yahoo.com/group/TS-850_450_690/message/8883 i have never seen the radio refered to as just ts850, except by radio ops. I have always seen them as ts850s or sat. they have always had a digital display, Mon, 08 Feb 2010 20:07:39 GMT Bob AD5VJ http://groups.yahoo.com/group/TS-850_450_690/message/8882 http://groups.yahoo.com/group/TS-850_450_690/message/8882 Is there a difference between the ts-850 and a ts-850s. I know that SAT means digital readout with auto tuner for Kenwood, but I see this rig referred to as Sun, 07 Feb 2010 04:43:16 GMT Zack Widup http://groups.yahoo.com/group/TS-850_450_690/message/8881 http://groups.yahoo.com/group/TS-850_450_690/message/8881 OK. It could be that the microcontroller circuit is bad. I haven't done anything with the ATU circuit so I am not sure how to track it down.

Here are what I found so far: 1. Both VC1 and VC2 can be manually turned by the main knob and VFO knob respectively in Sat, 06 Feb 2010 15:31:44 GMT avvidclif http://groups.yahoo.com/group/TS-850_450_690/message/8879 http://groups.yahoo.com/group/TS-850_450_690/message/8879 They are surge protection diodes.

VR14 does set the reference voltage for the ALC.

First off, when you manually tune it now, can you tell if the capacitor actually goes through its entire range when you rotate the control?
