Here is a mod I wrote up for the TS-2000 a few years ago. It addresses how to access the menu, the settings, and the software required.
While going into the service software to adjust the S-meter feature
I took lots of notes (didn't want to mess anything up!). If its
useful to anybody please have at it.
"Fixing" the anemic TS-2000 S-meter
Most people who purchase the TS-2000 are pretty surprised at how low
the S-meter readings are
compared to other manufacturer's radios. There have been lots of
discussions on TS-2000 Yahoo
groups and specific web sites about how the readings are truly
accurate compared to Collins
Radio standards. That may be, but the lack of S meter activity is
rather annoying and tends to
distract from an otherwise very fine radio.
I went into this adjustment modification with one thing in mind. To
be able to use the TS-2000
with the "band scope" function on Ham Radio Deluxe and N4PY software
on the HF bands.
The minimal S meter readings caused very low peaks on signals and
also missing of weaker
signals when sweeping with the band scope. I found that the amount
of S meter activity on 6
meters and up was satisfactory to me.
This "modification" is strictly a programming procedure and except
for removing the bottom
cover to turn on a programming switch, involves no soldering.
Hopefully it will help simplify
the steps necessary.
First obtain the "Service software" from either the Yahoo
adjust_ts2000 group or this link:http://www.ve1alq.com/zipped_files/ts-2000firmware.zip
This is a 20 meg file and can take quite a while to download.
Next obtain the memory management software MCP2000.http://www.kenwood.com/i/products/info/amateur/mcp_download.htm
or on the Yahoo TS2000 groups.
Lastly you need to get the "firmware" software from Kenwood:http://www.kenwood.com/i/products/info/amateur/pop_ts2000.html
The latest firmware as of this writing is v1.04 issued on January
Go into the radio's Menu and set #56 to 9600 baud. This will remain
the same for all of the
The same cable you use to control the radio with your computer is
the same for programming.
Using the MCP2000 memory management software "Read All" of the
radio's settings/memories and
save them for reloading at the end of the adjustments (note:
defaults to 9600 Com 1).
After saving the radio's settings with the MCP2000 software, power
the radio down.
Hold down the "NR" and the "MIC" buttons at the same time while
powering up the radio.
What will be displayed will be the "checksum" of the firmware that
is installed in your
radio. In my case it shows "bdEF". This is what hopefully will
show AFTER the adjustments!
This crosses to firmware v1.04. Other checksums that you might see
are "A89d" original
firmware, "6d7A" Factory firmware 4/2001, "f095" v1.01, "8bd6"
Factory firmware 5/2002,
"bb7d" v.102, and "4611" v1.03. You will be reloading the firmware
back into the radio
so be sure to jot this down!!!
Next you will need to remove the bottom cover of the radio. This
only involves the bottom
and no screws on the top cover need to be removed.
Locate the switch "S1" on the main board near right side/center (the
side the RIT/SUB knob is
on). Mine was hidden under a couple of cables, so look carefully.
It is very small and
has a silver finish. There is a VERY small black plastic toggle
pointed up. Its fragile, so
be careful! I would only use a small flexible wand to move
it. "On" is toward the front of
the radio, and "Off" is toward the rear.
Be sure main power cable is removed from the radio and turn the
switch to "on" (front).
Hook your serial cable back up to the radio.
Run the "Service Software" for the TS-2000 (FWS for TS-2000). I
found this software to
be kind of clunky to use and the help menu is almost worthless, but
its all that
is available to load the service adjustment firmware. The ONLY
part of it that I
used is the "adjust firmware write". Since you have already saved
using the MCP2000 the other features of the program are not needed.
Hook up the power cable of the radio but DON'T press the ON/OFF
switch on the front panel!
Click the "adjust firmware write" tab in the service software. You
will see a blue
bar as the firmware is loaded into the software. Then click
the "write to radio" tab.
This is where I had some problems with the software, it took a
couple of different
attempts to get it to work properly. I finally rebooted my computer
and then it worked fine.
Again you'll see a blue bar as the service firmware is written into
Reset the S1 switch to "OFF" (rear).
Remove the power cable and then reinstall it.
Stop running the service software, you shouldn't need it further.
Power up the radio using the ON/OFF key and the "A=B" keys at the
same time to perform a
full reset. The radio will prompt you to press the "A=B" key once
again to confirm.
When the radio is reset, once more power down using the
front "On/OFF" key. Then power up and
the radio should beep several times at you and show "ADJ" instead
of "Hello" on the screen. If
it continues to beep just press either the Menu key or the CLR key.
Now the fun begins! Power down AGAIN (yeah I know its tiring) and
then you will need to power
up once again using the "On/OFF" and the "MIC" and "NR" keys all at
the same time. This will
get you into the service menu adjustments!!!!! There are 127 menu
items that can be adjusted.
I HIGHLY recommend that using the "multi/CH" knob scroll through
each and every one and jot down
the current settings. It is very easy to lose the old settings.
I'll be posting another
document with my settings as I found them. There doesn't seem to be
any default listing
available on the net!
We are only concerned with menu items 23 (SSB S1 setting), 24 (SSB
S9 setting) and 25 (SSB
full scale setting). My settings from Kenwood were 23-48, 24-249,
The settings are changed by selecting each menu item and using
the "RF gain" control to adjust
the numbers on the right hand side of the screen. (Where the readout
is normally for the second
receiver). When the numbers you want are displayed, you press
the "+" key to lock them into the
menu. I know it sounds kind of funky, and it is but will make sense
once you are into the
service adjustment menu.
The settings that I found improve the S meter the best are,
Menu 23-5, Menu 24-122, and Menu 25-387. As you can see these are
fairly drastic changes and
you are welcome to change them as you see fit. But they were
arrived at with much trial and
Next you need to select Menu item "124" and then press the "+" key
once more to write the
values to the "eprom". At this point you can power down the radio
with the "On/OFF" key,
power it back up normally (it will again beep at you and
show "ADJ"). Go anywhere to check
out the new settings of the S meter. If they seem OK to you then we
will now write the
user firmware back into the radio!
Power down the radio and unplug the power cable. Set switch S1
to "ON" (front)". Plug the
power cable back in (DON'T power up the radio with the ON/OFF
Run the "TS-2000" update program (I used the one for v1.04 to
restore the firmware that I had
originally) and follow the prompts. The program works very well and
I had no issues with it.
Write the firmware back to your radio.
Remove the power cable and set switch s1 back to "OFF" (rear).
(This should be the last time!)
Plug the power cable back in and power up using the "On/OFF"
and "A=B) keys together
to do another full reset on the radio.
Next power down using the "On/OFF" key.
Again power up this time using the "ON/OFF","MIC" and "NR" Keys at
the same time. This will give
you the "checksum" of the user firmware installed. Hopefully its
the same as when we started!!!
Power down and using MCP-2000 software load back into the radio your
settings/memories that were
Power down, put the cover back on and enjoy your new ACTIVE S
The "band-scope" functions on Ham Radio Deluxe and N4PY software
packages now work wonderfully
showing weak and strong signals on the sweep! Note: for best scope
display the AGC should be
set to a "fast" setting.
