Hello All Mike Rowbottom mentioned the Apidictor recently. At present, two electronic engineers one in Ireland and one in the USA are working on a project to get an Apidictor up and running based on the original design by Mr Woods a BBC engineer in the 30s. I quote part of an e mail received from the American engineer recently. >I too look forward to having hardware, but with some trepidation. When we >can make working units our frustration will begin, inasmuch as we have no >idea how they should be calibrated. There was an original Apidictor about >30 miles south of here, but the owner died, and the unit has disappeared >into oblivion. Do you have access to an extant original unit? Do you >suppose Rex Boys has any idea how the Apidictors were calibrated? > >About the best I'll be able to do is to provide for trimpots (little >screwdriver adjustments), one to set the sound level at which the green >indicator goes off and the yellow comes on, and another for where the yellow >goes off and the red comes on. I will not, however know the settings for >these adjustments. > Is there anybody on the list who has any knowledge on the Apidictor or better still knows where I can get my hands on one. Any help will be greatly appreciated and I will arrange to update the list on progress when the model is working.
