I replaced the coax jumper cable (RG58) from my KX3 to my coax antenna switch with a new one and the birdies disappeared!!
A high quality shield, well soldered to a high quality connector, is critical to good performance. A high quality shield requires low RF resistance, which in turn means a beefy copper braid with a really good concentric connection at both ends. A high quality connector means Amphenol 83-1SP.
Real hams don't buy pre-made coax cables, they make their own. Pre-made cables are often made with cheap coax with junk connectors. And that includes "big name" vendors who have big ads in QST and CQ.
