Not familiar with the tx/rx you've noted above, but it sounds like you might be trying to mix air (tx) and ground (rx) models? Could be the source of your problem. If not, make sure both are powered up and that you've got the crystals in the right way and the right order (even on paired crystals, one still belongs in the rx and one in the tx).
