Topband: DX Engineering Preselector

[Lee K7TJR]

  Dave W0FLS is correct in that the Hi-Z system should need
 no additional amplification or any limiting to protect the
 receiver. The preamp as supplied should perform to about
 +30 dBm TOI. Johns problem suggests the need to check
 the system from end to end with a signal source of some
 kind to verify the overall system gain. I have sent John
 private messages to that effect.
