ICOM REPAIR, YAESU REPAIR, KENWOOD REPAIR, HAM RADIO REPAIRHey there,
Does anyone know anybody who could look into my old Kenwood TS480 around Chicago? When it warms up it stops transmitting, feels like it has something to do with "cold soldering".
Any suggestions for a repair shop will be appreciated.
Go to eHam.net, then reviews. Type in "Willco," then read the responses.
This is what I think it is and I will try that. If it doesn't work, I will seek pro helpA bright light and reading glasses will find cold solder joints 100% of the time. Just pull the cover and squint all over, then repeat after it has been warmed up to make sure. You can also prod connections with an insulated stick (top of a pencil) to see if they are moving around any and making a problem.
A hair dryer, to heat up spots, and a can of cold spray, to ice them down, can also help to pinpoint the area/part that is having a thermal issue. (Which is what many repair shops would do, as well.)
