Gentleman, A word of caution with the new Mitsubishi power bricks. Please be sure to lap the bottom side of the brick flat using a belt sander with 150 grit and followed with 400 grit sand paper to achieve optimum smoothness. No one is sure what they were thinking with the bottom side of the modu

Hello Eric, Skipp, and the Group! I concur with rtc's PA fix scenario. That is real accurate on the procedure and results that I experienced in the many PA repair issues I have resolved in the majority of Mama Mo's Maxtracs, Gm300, and 1225 mobiles in use as-is or repeaters. A seasoned tech li

Haven't tried it without a fan. I would guess that the giant heat sink on the original PA would probably handle the heat easily. My only concern would be the small contact area from each module; Would the heat dissipate properly? I have a PhD physicist business partner who could figure it out, b

Does anyone know where or does anyone have any primestar dishes they would want to part with in and/or around the Indiana county area. I am wanting to make a 2.4 ghz reapeater hop. These are the old oval fiberglass dishes. The finances are low on this project. Thanks for the off topic entry.
