Troubleshooting the Jove Receiver.
If the Jove receiver does not tune up properly it is likely due to a poor solder connection or an incorrectly installed component. If you have access to a voltmeter check for proper voltages as seen in Figure 19 of the Jove receiver manual. Incorrect voltage readings can narrow down your search for the problem.
Review the location of each component, paying particular attention to the orientation of the integrated circuits, transistors, diodes, and polarized electrolytic capacitors. If you need to remove a component use either solder wick or a solder sucker. Solder wick (Radio Shack Desoldering Braid 64-2090) is the least expensive method.
Place a clean section of braid between the tip of your soldering iron and the solder joint. Push the iron firmly against the braid for a few seconds, and the braid will absorb the solder. Remove the soldering iron and braid simultaneously. The component lead should be free. If not, repeat the process – using a clean section of braid. The more expensive solder sucker (Radio Shack Vacuum Desoldering Tool 64-2098) is a plunger-activated device that works by sucking melted solder off the board.
If all components are correctly installed then inspect for bad solder joints. One of the most frequent problems with the Jove kit is a poor solder joint. Use a bright light and a magnifying glass and look carefully at every single joint. Each joint should be shiny and the solder must flow smoothly around both the component lead and the solder pad. Resolder any suspect connections. Look for solder bridges, particularly between adjacent IC pins. Solder bridges are easily removed using solder wick.
