Ic-r3 hack

Author: Direct Dirt April 17, Amateur Radio. Memory channels on most modern radios can be programmed with PC to radio interface cables. I recently obtained an ICOM V rig from a fellow ham and decided to change the channel programming that he had been using to match that of my other rigs. Of course this meant that I needed to look into how to do this without punching a lot of buttons on the rig. So, back to the web and my best friend, Google.

I quickly found a plethora of schematics for clone cables. You get a huge alphanumeric memory system 50 channels in 8 banks plus 50 scan edge memories , 4-step attenuator, video and audio outputs, auto power off, a 4 position joy stick and BNC type antenna. A tone squelch system is built in to provide quiet stand-by. Many frequency and memory scan modes are supported.

The tone squelch includes two functions. The Pocket beep function alerts you with a beep when a specified station's signal is received. The tone scan function is used for the receiving signal such as for a repeater. The right side of the radio has a 3. Now come to the question What will be the voltage between point A and point Z?

Obviously, it will be the voltage of the battery or Power supply i. What will be the voltage at point B and point Z? Here we are measuring the voltage between point B and Gnd Gnd. So, when we measure voltage between point B and Gnd. Here we are measuring the voltage between point C and Gnd. In the diagram, we can see that there are two resistors before point C, and there will be a voltage across both of these resistors.

Now come back to our original circuit i. We can easily achieve these values if we are using normal tap water or underground water, because the resistance of normal Tap water or underground water lies usually between 40kilohms to kilohms. Now we will see the working of Automatic water level controller in Steps:- Stage-I Condition:- Tank is empty or water in the tank is below low-level sensor.

In this condition, we can see that one end of both R1 and R3 is going nowhere wires from these resistors are going to the high and low sensors which are just hanging in the air inside water tank.
