If you would like to improve the brightness of the display this how you =
can do it.  On the inverter board, there is an 18 OHM  1 Watt resister.  =
( R3502 ).  Replace this resister with either two 10 Ohm 1/2 Watt =
resisters, in parallel, or one 5 Ohm 1 Watt resister.  The result will =
be as follows..   Hi will be brighter, but not too bright.  A more =
pleasant looking display.  DO NOT jumper the resister as you can cause =
components to fail on the display board from over heating.  Note if you =
use a single 1 watt resister, the leads will be too large for the holes, =
suggest that you cut out the old resister and solder the new resister to =
the leads.  Otherwise you will have to enlarge the holes.  The resisters =
that I used were radioshack 10 ohm's. Which fit nicely..  Once the =
display is warmed up I can now easily see it across the room as well in =
sunlight conditions. =20

TIPs:  If you ever have a problem with the display, check these items =
first. A. R3502   B.  Fuse F3501  C.  Thermo fuse F3502.  D. Make sure =
there is 13v at pin 2 of J3501, if not, the problem is on the display =
board.

This should work on the MP  &  Field..  If some one has the schematics =
copied of the field scanned into the computer,  please Email them to me =
......=20

The original resister drops the 13V dc down to about 10V dc.  The new =
resisters will only drop the voltage to about 12V dc....   There are NO =
heating issues from this mod.  ONLY a much better display...

I make NO guarantee with this mod, do it at your own risk.. =20

I have a new (4 months old) 1000 field and the display is quite dim for =
my liking. Is there a mode for this that has the approval of Yaesu or =
the support of this group as being reliable?

Thanks fro the info,

Bill, K5ZQ
