So for the last 12 hour s or so, I have run with the alternate switch off. Just strange that it too k 12 hours to pop again. Like one of the guys suggested, when I do my tests I might find the radio draw is dancing around the 5A limit...so over time it would probably eat away at the fuse until it fails. I guess the easy fix could be to throw the 7.5 A in there, but it still bothers me that the rad io specs indicate the high end draw at tx should be 3.5A (going from memory here) or close to that. I am off to the field now and hope to gather some useable information today. Just hopeI don't blow a fuse out there...should get up to about 110 in Phoenix today.=0ADan=0A=0A=0A_______________________ _________=0A From: "Robert L.

Has anyone heard of an Apollo 706 radio? I recently bought a experimental that has an Apollo 706 radio in it but I know nothing about it and haven't been able to find anything for the wiring or operation. I don't even know if it is 720 channel or not. The operation does not seem vary intuitive to me as it is all pushbuttons. It is probably from the late 80's or early 90's. A manual or general information would be helpful.

I bought a modern regulator from Zeftronics (who, in a world of poor service, excel themselves at being at the top of the bad service list) and was about to install it when I noticed that there is also what is termed a 'suppressor' between the generator and the regulator. It is basically what I think is a smoothing filter - two inductors in series with two capacitors, one after each inductor, connected to ground. There are one of these circuits connected to either side of the generator (that is, on either side of the main windings) and one to the one side of the field winding. Since the original of this has disappeared from the aircraft I need to make another one, but I am not sure of what values of inductance and capacitance to use- does anyone have these values squirreled away somewhere so that I can make a new suppressor?

I have need of something that will display visually a rotating motor's shaft. A Hall Effect circuit would be fine, but I'm open to anyone's suggestion if they have a better idea how to monitor rpms of a motor. FYI, the motors will turn at a relatively slow 200-250 rpm (if that matters). If you know of a specific gauge, or LCD display, that could read these rpms, I'd appreciate that, too.
