Dear R C,
I have a Simrad
together with parts
that I "canabalized" from my broken Simrad
. Unfortunately I do not have access to my rudder
making it nearly impossible to install an RF300 rudder
feedback unit. It is however very easy for me to design a circuit that determines the rudderposition based on counting the number of rotations of an axis inside the drive unit. I would however now need to emulate a RF300 unit.
When I was reading through this thread I noticed that you wrote that the RF300 produces a 3400 Hz signal at its center position with a 20 Hz change for every degree, so for -50 deg to + 50 deg the RF300 produces a 2400 to 4400 Hz signal. Is this correct? Do you know if I can use a square wave form or do I need to use a sinus? Do you also know the amplitude of the feedback signal?
Thanks in advance for any help/advise given,
