IC7100 Mods

The Firmware Upgrade makes the radio meter show more power, but only slightly affects the output. Doing the Jumper Mod will give you a easy 100 watts PEP. Doing the Capacitor Mod also, will give you approx 130 watts PEP, but is "NOT" for anyone to do that is not experience in working with SMD, since everything is so small and close together.

As you can see above, the chip capacitors, 1508, 1509, and 1510 are all paralel , so exactly where the jumper is placed at the ends of them does not matter. The small point marked with the red 1 in the above photos is perfect.



The Mars Mod








This will take care of any of your HF or UHF Mars
needs, and any new bands added in the future.

Using one, or both of these sure helps. Cheap at Harbor Freight.

      

If you do not have the proper size soldering iron, or do not feel comfortable removing the diodes with one, you can use a Small pair of diagonal cutters, and remove the diodes by placing the cutters in the recess corners of the diodes on the spots shown, and give a squeeze. They cut very easy with a good small set of cutters.

Make sure the power cord is removed before doing any of this, and you turn it upside down and blow out particals from the diodes.
