How to Repair a Field Intensity Meter

If your RCA WX -2 AN Intensity Meter or your Eton Field radio has a missing cover spring or is broken, they will not function as well as they should or even stop working altogether. These meters use two springs to keep the antenna or cover in place in an upright position above the meter when in use. Unfortunately, these springs are no longer manufactured, so if the spring in your meter is broken, your meter will not function properly.

Meter covers have three electrical contacts that must be engaged before they can work. Of the three, two of them are for the antennas, while the third one is meant for the battery. These contacts play a key role in the meter’s functionality; that is why they should always be cleaned for peak performance.

If your meter is having issues because of a broken or missing spring, you will need to improvise to get it fixed.

How to fix a broken spring in your intensity meter

Since intensity meter springs for most meters are no longer produced, you will have to seek out alternatives. You can get alternative 3/8 inch springs at hardware stores. A good alternative is an expansion spring fitted to doors. If you get an expansion 3/8 inch spring, then you are good to go. Here are the steps to take.

1. Test the spring

The first step to take is to test the spring for tension. To do so, bend them at more than 90 degrees. If the spring provides enough tension when the meter is closed or open and does not create too much tension to keep the meter covers open, you can use it. By the way, you will need two springs.

2. For the Springs in place

You have to fit the spring in place. To do this, place them in the spacers in the cover and the meter. To get the right fitting, measure the threaded spacers and hack the springs into ½ an inch length each. Once done, place them in the threaded spacers.

3. Install other fixtures

At this stage, you need to install other fixtures like the lock washer, flat washer, and machine screw. Make sure they are perfectly installed.

4. Trim the copper tube

With scissors or a cutting object, trip the copper tube to give it the right amount of pressure to help the springs maintain an upright position, so they don’t touch the meter cabinet when the cover is closed or open.

5. Test the Meter

With all the fittings in place, you can now test your intensity meter. Open and close the cover and make sure it works without any stiffness and restrictions.

When fixing the springs in your intensity meter using DIY materials, ensure that you get the measurement right. This will ensure that you don’t disrupt the functionality of the meter.
