mfj-916 bad soldering.
they dont call mfj "mighty fine junk" or "mother f!@#$ing junk" for nothing.
this was used twice on a brand new radio. it caused a failure in the uhf pa module. my cost for the part is around $80. customer not happy! |

Re: mfj-916 bad soldering.
Looks like the inside of a passive coax splitter except the wire on those is hair thin.

Re: mfj-916 bad soldering.
looks more like sloppy design to me. i think proper screw-in jacks would have helped more.
bummer it took the pa with it.

Re: mfj-916 bad soldering.
And not acceptable design. Not allowing for connectors to flex without breaking the connections. Or rigid enough. The pin is not through a hole, just very short pin laying just above the PCB in glob of solder. That's bad that how this breaks.
Needs to have a solder tab in SMD style so flat part can lay flat directly on the pad and need less solder this way. Cheers, Wizard |
