Clarifier (Unlock) Modification:

Much controversy has centered around this mod. Many people complain that it simply doesn't provide enough "slide" to do much of anything -especially reach the "A" channels. In my own experience I tend to disagree. Yes, there are remedies to this by tinkering with the clarifier circuit in various ways, but why? Oh, I've heard it many times... Some people claim that "unlocking a clarifier to slide at least a full channel up or down is the only way to go". But wait, isn't that what the channel selector knob is for?!?! In reality and simplicity, the purpose of having an unlocked clarifier for talking on sideband is to match your transmitting frequency with the other person's receive frequency -thus making communications much easier. In other words, if your clarifier is unlocked and you tune them in on receive, you will also transmit on the same frequency. And this mod excels at accomplishing that task very well.  Still want to get to the "A" channels? Well, there's a 10kc mod for that as well. First things first. Read on...

There are currently several known ways to unlock the clarifier on the DX-959. Here are two:

Method 1:

First, remove power (unplug) to the radio. Remove the bottom chassis cover of the radio.

Remove JP195 and JP196.

Connect a jumper wire between J14 pin +8V and J9 pin F1. 

Method 2:

Remove power (unplug) to the radio. Remove the bottom chassis cover of the radio.

Remove R113 and D68.
