I dropped my IMax and changed the coax. Then I added the coil. Back on the air again!

nice looking ..... but i would have used less wraps on the coax choke .
yours is optimal around 9-13 MHz. rather than 27 MHz.

Be careful when securing your coax!

Terry,
Don't want to be a nit picker but I would be concerned about using plastic tie wraps to secure your coax to the mast. The signal passing through the coax is very sensitive to maintaining the circular shape of the dialectric. Pinching [deforming] the coax will create reflections at those pinch points. You may well not recognize a change in your signal performance but it won't be as clean and pure as it could be. Just a heads up!

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
