TM701A.5

TM701 Hints...
I've added the mods contained in TM701A.1, 2, and 3. They all work
just like the mod file says. However, the descriptions in the file are
not all that obvious to follow inside the radio. Here are some hints
to make the implementation of the mods easier for you.

"GREEN WIRE" Mod:  This one is very easy. When you remove the top cover, 
ûïôýyou will see it looped and sticking out on the front left side. Just
clip it.

"X-BAND REPEATER JUMPER": although the "figure 2" included with the mod
file is pretty clear, some additional definition may help you. The "@"
in the figure from which the jumper originates is actually a chip resistor.
The jumper goes from the left side of that chip resistor to the third
pad on the line of pads (which is a connector on the other side of the 
board).

"EXTENDED VHF/UHF"  The mod describes adding diodes D207 and D209. There
is no silk screen showing these diodes on the board (at least in my 
copy of the radio). Their position is less than obvious.
  Looking at the foil side of the PCB, you will find the positions directly
behind S209 and S207. You will notice two small pads directly behind
S205 which do not have holes drilled in them. The diode goes between
these two pads (D209). It takes a very fine soldering iron tip. Also, it
is much easier if you pre-form the leads of the diode.

The position of D207 is even less obvious. Again, its location is directly
behind the switch (S209). The top pad is actually TWO square pads which
have a trace between them. The bottom pad is directly below the pair and
in the middle...it is NOT directly below either of the two. The diode
goes between the pair of pads and the bottom pad. All are square. Again
pre-form the leads and use a small iron. Also make sure that the diode
leads don't short to any other pads.

Good luck. Take your time and be patient.
