Radio Shack parts
Although Radio Shack does indeed sell the appropriately sized type "Q" connector for your Icom receiver, it can get expensive when you consider you also have to buy the appropriate power cord to go with it, as the connector has a special two-prong connection that mates with the power cord you must also purchase along with it.
Radio Shack
used to sell a simple solder type "Q" connector and that's all you had to buy. Then you would solder your own power cable to it of the appropriate size. Most people have lots of power cables of varying sizes laying around that can be used for this purpose. I for one am always cutting off and saving old power cords from non working wall-wart power supplies in the event I can use either the connector or cable at another time for something else. Unfortunately, The Shack makes you buy unnecessary crap when all most people really need is just one simple little connector and nothing more :roll:
Radio Shack also used to sell a replacement 3.5mm mono speaker cable to replace old speaker cables that were either cut off of maybe the outer insulator started falling apart. You used to be able to go to The Shack and buy an inexpensive replacement "pigtail" that had an attached mono 3.5mm connector on it. Now you have to buy a separate 3.5mm connector and an entire roll of wire and spend five times the amount of money than you did when they simply carried an inexpensive direct part replacement in years past.
I like Radio Shack for certain things but it's clear they've restructured their parts section to force people into paying far more than you really need to for even simple replacement components
