Subject: TS870 MARS/CAP Modification

From: Howard Ryder From the factory, mine had this:



B7 1E 1E SWR PROT



Go into B7 and by using [RIT/XIT] you can vary the left number from

00 to FF (256 different levels).

Pressing [UP] will update the right number.

BA menu sabes your changes.



B8 - SWR meter

==============

This will adjust your SWR meter. All 870s that I saw what swr meters

that worked really well, so if your's is working fine leave this menu

alone.

If not, try this:you will need a 150 ohm dummy load (yes, not 50 ohm,

but 150 ohm). Hook up the dummy load to the rig. Go to B8 and press

[SEND]. The left number will change. Pressing [UP] updates the right

number and menu BA will save your changes.

*WARNING*:doing this with a 50 ohm dummy load will ruin you swr meter

and will lead you to wrong swr readings (if you use this meter).



B9 - FM Deviation

=================

Factory settings on several 870s seem to be:



B9 80 80 Fm DEV



Going into menu B9 and using the usual [RIT/XIT] button will change

the left number. [UP] will update the right number. BA menu will save

your changes.

To adjust this menu properly you need special test equipment, so I

would advise you to stay away from this one.



BA - System

===========

Refered many times before.

Usually:



BA Ready EEPROM



"Ready" means that you can record on the EEPROM.

Pressing [UP] will record *any* and *all* changed menus.

Reply after recording must be:



BA Good EEPROM



BB - Display

============

This will light up all the LCDs and all the leds on the rig.

You can check for a bad LCD or for not working leds.



So, this is it.

You can find more information on this menus on the TS-870S service

manual. Look on page 92 and the following pages.

*I am allways* interested in learning more about this menus (and also

other menus) on the 870.

If you are an Kenwood TS-870S owner and want to change toughts about

your rig fell free to e-mail me at:



cunhalopes


I am interested in getting the factory settings of these menus for

different Kenwood TS-870S. If you send your data in, please send also

the serial number of your rig.

Remember that this article may contain incorrect informations (I've

done my best to avoid that from happening). Also the info contained

here can easly get you in trouble.

So remember the golden rule:"if my new setup is wrong I must be able

to go back to the original factory value".

Keeping that in mind myself, I wish you

73s.
