Eric and Bill,
I'm thinking that perhaps my previous posting got lost, as I responded to an older post on the subject of Aquastar modifications. Perhaps I'm just anxious to hear if my suggestion has any merit, or if it's cost effective to do at all. Thanks as always Bill for your helpfull response.

Eric, if a may, I would like to make a suggestion for any future modifications to the Aquastar. While reading the archives I learned that Terry in Hawaii did a lot of the beta testing on your prototype Aquastar and that the external frequency adjustment was added to allow the user to filter out RF interference (apparently there was a lot of interfernece on Hawaii) without impacting the sensitivity of the unit.
In my short 8 months of using the Aquastar I haven't needed to use the frequency adjustment, although I do detect near an Air Force base with some fairly powerful radars, and who knows what other transmitters. What I have found is that I do need to adjust the internal SAT and Sensitivity (7/8 turn) pots as I work different beaches. These adjustments, of course, require opening the case, brushing the sand off my fingers and hoping that I don't contaminate the pcb while experimenting with the settings.
It would be very useful to have these two adjustments available externally, although I do realize that more penetrations would increase the chances of a leak. Perhaps there is a way to install magnetically adjusted trim pots as I've seen installed in watertight pressure transducers. It would be great if the two pots had small adjustment knobs installed on top of the case with the other external adjustments.
I've enjoyed the Aquastar immensely and especially enjoy being able to learn from the "Master" and others on this forum.
Respectively,
Don
