<div class="moz-cite-prefix">In the grand scheme of things, if a
person has the ability to add wires to the CM108/CM119, removing
the audio connectors is a piece of cake.<br>
<br>
Besides, all of the better modifications tell you to cut the jacks
off the board, and then do the clean-up. Some modifications
require the jacks to be removed, so in those instances it is a
necessity. <br>
<br>
Bottom line - cut the bands or pins with a good pair of cutters
first so the jack falls off, then minimal heat is required to
remove the remaining stuff. Same goes with the USB plug in those
mods which require it.<br>
<br>
A bigger problem is those modifications that do NOT instruct the
builder to remove the MIC bias resistor. Many radios with DATA or
discriminator audio outputs have a fairly high output impedance.
If you don't remove the bias resistor (commonly around 1k) you can
severely load the discriminator and the radio won't work
correctly. Removing the resistor accomplishes two things. First,
it removes the voltage on the MIC input lead and eliminates the
need for a coupling capacitor. Second, it raises the input
impedance so loading of the discriminator doesn't happen. Sure,
on those installs that use speaker audio (yuck) for driving the
FOB, there are no loading effects, but why buy a coupling
capacitor when one component can be de-soldered or otherwise
removed? You aren't saving this component, so you could care less
if it gets damaged or lost in removal.<br>
