bobina dch.rar

[folharin]

this circuit is part 85 of my dch front
what is the purpose of it?

[ikumi5]

its a transmitter. pin 2 and pin 6 have to connect its other to properly run this transmitter

Hi folharin

I have a question for you. Has i understood, this transmiter is fom your DCH 85, correct?
An if so, what is the coil wire diameter?

What are your expiriencies with DCH 85?

In advance many thanks

Nelson

coil tuned to 42.5 Khz..... ??????


Contur calculation
Circuit capacitance: 100 nF
Frequency of a circuit: 42.5 kHz
=>Inductance of a circuit: 140.237 µH
----------------------------------------------------------------------------

Inductance calculation
— Multilayer coil
Coil inductance 140.237 µH
Diameter of former D: 40 mm
Length of winding l: 5 mm
Diameter of a wire d: 0.3 mm
=>Thickness of the coil c: 1.313 mm
=>Resistance of the coil 1.717 Ohm
=>Necessary length of the wire: 7.034 m
=>Number of turns of the coil: 54.699

drtech, of where take you these messurements?¿?¿¿¿¿ you have a dchs 85?
may be these trasmiter send any low armonic
drtech de donde tomaste esas mediciones? tienes tu una dchs 85?
puede ser que ese trasmisor mande algunas bajas armonicas );
