Yaesu VX-150 Resetting it's memory periodically
Hi, I have a VX-150 that's 1 month old. It periodically resets it's
memory. Initially I thought it was to do with the power in my truck. However this is not the case. It has done it even without the power connected. Anyone have Ideas? K0BAZ |

Howard- I have a brand new Kenwood TM-742 that does it. I took it apart, thinking the battery might be bad but it wasn't. Then I noticed that about half of the plated-through holes on that circuit board weren't! (You have to use a magnifying glass) Apparently temperature variations inside the car sitting in the Florida sun, causes shrinking and expansion of the circuit board, so parts that normally touch open up, removing battery power from the memory. Perhaps it will solve the problem if I re-solder the holes with a tiny wire to connect top and bottom of the board. Unfortunately some of the holes are blocked by components on one side, and my soldering iron tip is much too big. Fred K4DII |
