Due to aged eyes and ahakey hands I am going to do a Mars mod that requires connection a couple pads. What the heck product do I use ( specific please on brand, etc ) and does it require heat to cure, and if so what is the used as a heat source?
 

The only solder I would use for that is the solid variety.

Solid until you heat it with a soldering iron so it flows onto and bonds to the work surfaces. In your case, foil pads on a printed-circuit board.

I remember a "liquid solder" product from years ago. It was an epoxy glue that was saturated with metal particles.

Haven't seen it promoted in a long while. I have never tried to use it.

I concur with both of them. Use regular solder to bridge the pads and be done with it. Liquid solder is not what I would consider to be permanent for any electrical connection, especially in a mobile radio environment.

Sounds like you have a Yaesu 891. I did mine and I don’t have steady hands (69 years old). I put a pointed tip on my soldering iron, got it good and hot and only used a teensy bit of solder. Only took a sec. You got this. (y)

    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
