RE: Radio help.
It could be that the board has "plated thru" holes, where the solder flows all the way through the holes to both sides of the board. Very tough to get "desoldered". Go to your local Radio Shack, and get some stuff called "wicking braid". This is a narrow copper braided stuff, that is saturated with soldering flux. Place the braid on the solder location, and heat. It will suck all the solder up into the braid, making it possible to wiggle the connector, and break it loose.
