Please help, where do I start?

Scientifics has up to 2 foot dishes. I used the hardware (dish and handle) with a Primo Microphone (EM172). A Radio Shack electret mike worked well and I was satisfied until I tried the Primo low noise mikes and they are only two wire mikes, too. Ditched the Shack mike. I started out with an Olympus WS-400 digital recorder and got really got good results but I like the DM-420 and DM-620 better because I also use the recorder to learn bird calls and songs and they will randomize playback.. Here is the link to the Primo microphones. http://www.frogloggers.com/FORMgallery4.htm The 12/04 “Nuts and Volts” has a good design for a parabolic microphone using a dish from Edmund Scientifics (about 30 bucks).

As long as I could verify, those guys at bestparabolicmicrophones.com are the only on the market making available more than 30Megs of downloadable archives for their microphones and also offering customization capabilities. I would suggest you to contact them... Bob, I am afraid that for 1000 meters away you will need a totally customized microphone and that will cost you pretty good money.

Filtering as the hearing aid mfgs. do does not really work because the background noise is almost always other people talking. Filter them out and I filter out the person that I am trying to hear. I would like to add a very directional mic to my H-A input in place of the normal mics. The input part is easy because I have inductive inputs and a neck loop to couple to the H-A's. After reading your report, it seems as though a flat directed mic would work best in this case. What do you think? Has anyone else asked this question?
