RE: Receiver swapping
There is one problem with swapping any electrical device with male and female connections. Every time you plug and unplug, the resistance goes up. In other words the connection gets loose. I used to work at a labrotory testing male and female connectors. I would do a resistance reading on a connector, then plug and unplug it 10 times,then do another reading, the resistance would go up. There are exceptions, a very good connector will not. I don't know about your device, but I doubt they are nasa quailty.
