Thanks for all the comments to my questions about "New Preamps" both on the BB and off list. I have ordered two from AR2 and I'm not going to worry about signal attenuation by the nearby pine trees.

Bryant, In the spirit of learning by doing, a part of Amatuer Radio, you have taken the first step. How well a preamp will work for you depends on many factors. The next step if things do not work well is to find ways to determine why by, seperating out overload, noise floor, antenna pattern, ground noise, etc. Now you are into learning! The most important part is not to give up until you have all the answers.
Good Luck, Art KC6UQH

Hi Art, KC6UQH
I agree with you and I believe that the best way to learn all the above factors is to read "STUDY" the following article by James R.Fisk, W1DTY (SK) publisched in the Ham Radio Magazine october 1975 pages 8 to 25
"Receiver Noise Figure ,Sensitivity and Dinamic Range ,What the Numbars mean"
This article is a complete discussion of receiver sensitivity, intermodulation distorsion, cross modulation, and gain compression, and what they mean in terms of performance.
Since the above Ham Radio Magazine october 1975 is difficult to be found I can send a zipped file of it to everybody is interested.
