ALONSO PD MISSION ACCOMPLISHED V1,V2

[Jeg]

I get a coil formula for the Alonso PD passive receiver that can detect a 1,5V battery spark 2,20m distance, my question, someone here get this distance or more with the passive receiver ?

Hi Morgan
The length of cable that you make the 1,5V spark is important. Different lengths lead to different distances. I think it was mr humhum that he proposed a 60cm length as a reference. What was the length of your cable doing those measurements?

my receiver catches the 1.5 V battery spark with 30 cm cable, at a distance of 3.80 meters.
Does this mean anything on the field?
Nothing at all.

There should be no cable length, but a loop in the form of a net with a diameter of 30-40cm.https://www.longrangelocators.com/fo...ad.php?t=19427

Hi
It is just a common method to compare sensitivities between devices. Nothing more.
But if it is to compare then length plays a significant role.



Thanks pahom. Very handy.



Have you tried guys to sense a piezo-lighter with your pistols? At what distance do you get the spark?


ps. By the way, rxlock...3,8m..impressive. Thanks

There are many options for Jagu. With a piezo, if you do such maneuvers, then from 20 meters, you can fry the transistors on the go. They seem to work, but they are really a kerdyk. Something like this! So only 1.5 volts is just right. Thank you, THANKS!

Is ferrite sensitivitie to the hand in Pd alonso?

[Geo]

If i remember right.... No.

[Hosin@2021/shahroee]

Thank you for your response mr geo .in active and passive mode (both on ) . Pd alonso how far senses a coin with a diameter of 2cm ?

[Geo]

If tuning is ok then it locates the coin near to 3m.
The basic problem is that PD is not so stable and detuned very often...

[Hosin@2021/shahroee]

Tanks for reply
In Pd alonso , detect coin in active_passive on and only active without passive is equal (test coin in air) ?
Best wishes

[Geo]

At active mode (with passive receiver off) it works as a simple metal detector, so catches the coin from 10...15cm (air test)

3 meters on air or recently buried or long time buried ?

3m for buried coin if it has create phenomenon.

Tank you so much geo
In active _ passive mode (both on )how far can catch spark 1.5v ?
Best regards
