For the sake of experimentation I bouth this white's DD coil for the models DFX / MXT /M6 /MX5.
Anyone has info on the connector's pinout? Thank you!

Carl Moreland info
White's DFX concentric
Rx 1,2 13.8mH 36 ohms
Tx 4,5 540uH 2.7 ohms
White's DFX DD
Rx 1,2 14.2mH 55 ohms
Tx 4,5 680uH 3.5 ohms -
Good info. Still I need to know these coils are attached to the pins of the connector.Originally posted by kt315 View PostComment

If you have the coil, loosen up the connector and look at the wires and the pins.
There will be two Red and a white wires, each with a braided shield surrounded them.
I just removed a connector off a DFX coil but didn't write down the pin numbers as I am using it for a different application with different connectors.Comment

1 and 2 pins are receiver coil - Rx 1,2 13.8mH 36 ohms
4 and 5 - ...
or, what you mean writing 'pins of the connector'?Comment

Большое спасибо, кт, уже разобрался. Величины виток польностю совпадают.
Upon measuring, the inductance values are correct.Comment

Carl is always correct because the expert - 'Most numbers are based on several coil measurements, including different size coils for a given coil type.'
i also see a data -
White's 300
TX Coil:
L--> 548,5uH
Q--> 1,27
C--> -46,15uF
R--> 2,72 Ohmios
Rx Coil:
L--> 13,6mH
Q--> 2,16
C--> -1,86uF
R--> 94 Ohmios
and probably Vision type that compatible (i suspect in it)
Whites V3I coil specs
Because I'm an electronics tech with a curious mind I had to do a little investigating with my coils. This is what I've found.
The Rx portion of the coils is on pins 1&2.
The TX portion is pins 4&5.
You can see the pin numbers if you use a magnifying glass.
The resistance and inductance of the coils are as follows:
Eclipse 5.3
RX= 30.8 ohms 14mH 40 Rings
TX=3.3 ohms 561uH 19 Rings
Eclipse 4x6
RX=50.9 ohms 15.6 mH 29 Rings
TX=3.3 ohms 545uH 17 Rings
Eclipse DD 6x10
RX=55.2 Ohms 14.0 mH 31 Rings
TX=3.4 ohms 550uH 19 Rings
D2 Stock Coil
Rx=44.1 Omhs 13.73 mH 32 Rings
TX=3.3 Ohms 550uH 21 Rings
The rings is a "Q" test of the coils and is an indicator of shorted turns.
As you can see the TX and RX of all the coils is similar both for resistance and inductance.
I was able to measure the inductance and "Q" with a Sencore LC103 test set I own.
This info should help anyone if they believe they have any coil problems.
I'm assuming all my coils are good and from these results I think I can safely make this assumption.Comment

Oh ****... there are two capacitors in the coils. I'll have to remove them somehow.Originally posted by kt315 View Post
But then again that's the 300, perhaps not the case of my coil.Comment

Anyone knows whether White's DD coils are induction balanced?Comment
-
There are no capacitors in coils made for the DFX and MXT. The DD coils are induction balanced
for all the VLF and multi-frequency.
Pin1 RX shield
PIN2 RX
PIN3 NC
PIN4 TX
PIN5 TX shieldComment

i have not good pics on MXT coil inside, but yet found on Vision, a schematic and see a pic of coil from ru forum.
there are some capacitors with low value and some resistors. guess those are some kinda an antinoise filter,
no another mission. resistors are for accurate phase tuning.

Kit
The one I opened years ago was a concentric. It only had a fixed resistor and a ntc(negative temperature coefficient) resistor in series with the TX coil and nothing on the RX coil.
The DD looks differentComment
-
nothing on RX side be cause a transmitter signal is square form and you can not simply to set a noise filter there be cause getting smoothing besides a clear form.
some people stubbornly is proving that RX coil has the resonance if seeing a capacitor parallel in IDF/XLT coils. NOthing of resonance there to be.Comment

i asked a RU forum and one gave me a clear pic with markings and measured values.
