[TenTec] Re: Paragon Question - Lack of sensitivity

If these are the diodes that switch in and out the input 
band pass filters, you are better off with pin diodes which 
switch much slower than 4148s. The reason is so that strong 
incoming rf does not switch the diodes that are supposed to 
be on (or off) for the band you are using. This was a big 
issue which became popular about 10 years ago. There are 
some kits available to convert the fast switching diodes to 
pin diodes. But, don't go and wholesale replace every diode 
in sight. I think some of these kits were somewhat ill 
advised. Your receiver may use pin diodes already in many 
places.

It's a silicon switching diode. If so, I'll run out and get 
a handfull.
