t2 teknetics coil

[Skippy]

Henrik, stop confusing the man, The F75 coils are DIFFERENT. TX on the F75 is single-ended, on the T2 it is balanced. RX coils are the same.

T2 it is center tapped tx coil. i already opened the plastic cover. i see graphite/carbon paint but cannot find any wire should be connected together with graphite paint. sorry i cannot upload the picture, my phone camera got a problem. so which wire should be as shielding wire?. TX wire or RX wire?

[Skippy]

I would recommend connecting the receive coil shield to the graphite painted surfaces.

i will try. 10q

If you decide to open the coil, you should buy a Teknetics coil cover. You can use this to help re-seal the case, using silicone sealant. The inner surface of the lower case should be graphite coated, this needs joining to receive-coil ground.

Welcome. I have a question about the coil T2, identical behavior in the post 1, which is the wire and how many turns and in which direction. Since this is a biaxial coil, there is little information on the forum.

Welcome. I reiterate question since my coil winding is damaged on the TX. I will try to attach photo!

Based on mathematical calculations, I think the transmit coil will be 36 turns, centre-tapped and the wire diameter should be 0.55mm. If you are rewinding a new TX coil, I suggest adding two additional isolated single turns of wire, so you have 36T and 1T and 1T This allows you to have 34T, 36T and 38T by using both windings.The finished inductance should be 665 microhenries and 1.8 Ohms resistance. Thank you for posting the photo.

Thank you for your prompt reply. I think that it will not scroll coil because it is flooded, but I will try to fix it and connect it.
Can you explain the construction of the coil and coil wiring diagram. The pin 3 to pin 4 is a break in the circuit.

you should open cover as shown only before open back side, and check the cable connected to pcb inside the coil/cover.

I welcome. pcb a cable with connection is okonly the issue is in securing coil. When installing coils super-glued glu and a hot glue on the end of the epoxy glue. More details at a later date. Regards
