Key Points
〜か何
( か = or something like thatTetsuhiro is asking for a radio, but he is not insisting on that exact item.
The expression leaves room for any similar device that would let him hear the broadcast.
ラジオ is the example, not the full limit
ラジオか何
( か means “a radio or something”.The point is access to the game or news, not specifically owning a radio.
ありませんか is a polite request
The line is phrased gently because he is asking to borrow something from another person.
That politeness fits the hesitant opening あのー.
