Here is an example:

new Ext.Viewport({
	layout: 'fit',
	items: {
		xtype: 'form',
		items: [{
			id: 'radio',
			fieldLabel: 'Radio',
			xtype: 'radio',
			name: 'radio'
		}],
		tbar: [{
			text: 'Check',
			handler: function(){
				Ext.getCmp('radio').setValue(true);
			}
		},{
			text: 'Uncheck',
			handler: function(){
				Ext.getCmp('radio').setValue(false);
			}
		}]
	}
});

ps. But normally, you don't uncheck a radio...
