[TenTec] {TenTec} Noisy Corsair II

[ke4id]

Hi, Steve,
I have a Corsair and did a couple of things of things to lessen the 
noise and make the rig more sensitive.
-I put a low noise broad band bipolar amp between the 9 mHz filter 
output and the passband tuning board.  This made it easier to copy 
weaker signals.  I believe the receiver noise figure is too high without 
an amp here.  I think the Omni VI used a jfet amp.
- I inserted a three pole filter made from  9 mHz crystals from Digikey. 
It replaced the ceramic coupling capacitor that goes to the input of the 
mosfet product detector.
