My Digital Pulse detector Delta Pulse 3

[hadi-dindar]

sorry friends
my first problem solved and now i have 12 vot in this pins
but i have now problem with regulation 5 pin of d6 for 6.4 volt
have only 3 volt in ths pin

[hadi-dindar]

i think 5pin d6 voltage depend on coil
now my problem is frequance
i have 201 hz in circuit
how i can reduce this freuance

Hi hadi-dindar
--what are the specifications of your coil?

How many turns of wire is in your coil ?
what is the thickness of the wire ?
what is the diameter of the coil ?

Hi hadi-dindar
-Any Delta gives continuous sound defect in the bad coil.
--RE,,what specification of coil tu , mm ?
-Addition in this(DP3) case also there is defect in PCB.

@Biogas,

i made pics of my DP3 and hope that some of your questions will be answered this way.
The mini LCD form ebay hasn´t arrived yet, so i took another K0108 GLCD.
The coil has 460uH and 3.6 Ohm.
