The message explained how to get into the "Hidden Function Menues" and what to do there. Since there are today more TS-850 Users, here comes the copy again (see below). Furthermore I am able to say, that: - HELLO Morse function is executed only once a time at Power-On, - the "mystic" Extended Function No. 08 (without menu item description) shall expand the transmitter range from 27.5 to 28.0 MHz (can't confirm that, cause I've got a gen. cov. TX) - the checksum of my transceiver (summer '92) is "6972", - the checksum of the transceiver (May '93) of our club station is "50c5", - there seems to be no functional difference between both tranceivers! If you have more information, please let me know.

This can be easily removed to bring the sensitivity of this band into line with the rest of the receiver's coverage. Locate the RF UNIT and locate the rx filters under a removable shield. Remove the screws holding the rf unit to the chassis and carefully lift the unit up so it can be turned over. It may be necessary to unplug some of the leads to the board. On the right side (under the filters) locate R7 and R8 (150 ohm) and R9 (33 ohm). Remove these resistors and replace the 33 ohm resistor with one of the 150 ohm ones. Replace R7 and R8 with a wire link. Restore the unit and the mod is completed. 2/ For some reason the cw sidetone level is not adjustable from the front panel. This mod uses the monitor control to adjust the level. Locate the IF UNIT and at the rear is the preset sidetone level control. It is not necessary to remove the board for this mod. Near it is R239 (330k ohm). Cut the printed track between R239 and R223 (4k7 ohm) at the R239 end. Solder a wire link between the end of R239 (that used to connect to R 223) and pin 2 of IC7 (monitor amplifier). Adjust the cw sidetone preset for maximum volume. The level may now be controlled by the front panel monitor control. The monitor switch will not switch the cw sidetone off but will work as usual otherwise. 73's from Grant in sunny Blenheim.

On ICOM rigs it does not require any modification at all as this is a feature built-in from the factory. On ICOM rigs if you push the connector halfway into the headphone jack you have the sound on both the loudspeaker and the headphones, then if you push it the whole way in its only on the headphones. Unfortunally this is not the case on the TS-850S. The headphone jack is a little different made on Kenwood rigs, so this modification does not allow you this "halfway" feature described above. But still you are able to have the sound comming from the loudspeaker and the headphones at the same time. Modification. ============= Note! This modification works on both mono and stereo headphones. 1. Remove all knobs at the front of the radio. 2. Remove the front. 3. Remove the very small unit (E/6 page 57) that contains the phone jack itself. 4. Install a jumper between pin no. 1 and pin no. 2 on the CN8 connector. That's all! See you down the log! 旼컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴커 � �袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴� � � � 栢께굇같 73's de Stefan in Leksand (JP70MR) 같굇께栢 � � � � 栢께굇같 @ SM4TYA.W.SWE.EU 같굇께栢 � � � 훤袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴暠 � 읕컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴켸 ---------------------------------------------------------------------- One of the minor draw backs to the TS-850 as a CW contest machine is the inability to use the internal keyer in conjunction with an external keying circuit such as a personal computer or auxiliary memory keyer. As designed you must manually throw a switch from internal to external keying to switch between one or the other. To make matters even more inconvenient this switch is on the back of the unit and is not readily accessible during normal operation. Simply said this modification involves running a new keying line from the junction of S1 and D51 on the IF Board. For convenience this additional keying line can be wired to the DSP1 and/or DSP2 RCA phono jacks if you do not use the external DSP unit. The modification to the unit to resolve this problem takes less than 30 minutes to accomplish and can be done without "permanently" modifying the unit which would detract from its future resale value. If you don't use the external DSP unit then the two RCA phono jacks marked DSP1 and DSP2 can be used as additional keying input jacks as will be outlined below. If you use the external DSP unit then the modification can still be accomplished by running the external keying line out on a "pigtail." I highly recommend the purchase of a service manual which will greatly improve your ability to indentify the circuit points involved in the modification. Considering that the radio costs $1500 what's another $30 to keep from messing it up! By the way compared to the two TS-930's that I nursed through the 80's, this radio is a breeze to trouble shoot and repair which I have had to do twice through no fault of Kenwood (long stupid story ~8>). From here you proceed at your own risk, if you fry the radio DON'T CALL ME. A precision low wattage solder pencil for doing surface mount soldering is recommended, If all you have is a 150 watt Weller solder gun then read no farther your better off taking the unit to an expert rather than "melt" the circuit traces. I assume no risk for the accuracy or completeness of the enclosed information. All yee who enter here embrace all hope for you may likely have a better contest radio when you are done. 1. Turn the unit upside down with the back of the TS-850 toward you. 2. Remove the bottom cover. 3. In this position the IF board is on your left. 4. Remove all the screws holding the IF board to the chassis. (put them in a jar or something for safe keeping). 5. Unplug enough of the cabling to allow you to tilt the board up so that you can access the bottom side of the board underneath S1 the "External/Internal" keying switch. 6. On the bottom side of the board directly underneath S1 you will see 6 solder pads arranged in two rows of three pads each. 7. The middle pad on S1 nearest the back of the radio should be GROUND, solder the braid of an approximately 9 inch piece of small audio style shielded cable to this point, being careful to dress the coax so as not to short to other circuitry. 8. The middle pad on S1 in the next row up of three pads is the keying line. Solder the center of the shielded cable to this point. 9. Route the other end of the shielded audio cable through the chassis in the vicinity of the DSP jacks above. 10. Carefully inspect all solder joints for shorts, etc. Replug the wire harnesses unplugged in step 5 above and reassemble the board to housing. Reassemble the bottom cover. 11. Turn the unit over and remove the top cover. 12. Find the DSP input board with the three RCA phono jacks on it at the rear of the unit. The two DSP jacks are on the right when facing the rear of the unit. There are two connectors on this board (a 2pin and a 4pin). Unplug the 4 pin connector. Obtain another 4 pin connector and connect as follows (or directly solder to the underside of the board as follows) If you only need one additional CW jack then ground is pin 2 (closer to center of the radio)connect the braid of your new key line to this pin. The input from the middle RCA phono plug is pin 1 connect the ceneter conductor to this pin. Like wise if you want two additional CW jacks then do as above plus add a short between pins 1 and 3. If you want a small RF choke or some ferrite beads on the center conductor of the audio cable may prevent keying problems in high RF field environments... 13. Close the unit up and switch S1 to INTERNAL keying. You should now be able to key the unit via the internal keyer (Via the standard key input jack) or with an external keyer or computer via the old DSP jacks, without having to switch S1. -------------------------------------------------------------------------------- By N6TR and possibly others, with zener idea added by K6LL.

We (kantronics) have had others report the same problem, and the following response was prepared by our service department: Some adjustments in the radio and in the kam may be necessary when using these connections. SOLUTION: Decrease the gain in the kenwood radio rear panel audio input circuit (may be labeled vr18, check your radio manual). Increase the afsk output from the kam (remove jumper k5 for maximum output). Set the kam to transmit in rtty mode, and radio in ssb mode, adjust vr18 (or gain control in radio that controls rear panel audio input) for the radio manufacturer's recommended output when using rtty. Now, when using the front panel microphone, low-level noise on the rear panel input will not be picked up or added to microphone audio.
