Is this the results I need to be seeing with my scope for the Deus2?

I'm no where close. Built another coil using crafting wire that seems to have a coat of shellac. 2" in diameter. Measures .11 mH and .7 ohms.
Not sure but the wire is white like maybe some kind of tin.

The Russian video has not got correct triggering but you do

My bad ... Thought the picture was your scope.

The exact design of the pickup coil won't make a whole lot of difference. One thing about MF waveforms is they are hard to trigger on. You need to set the trigger holdoff to just a little longer than the overall period of the waveform.
Show us what you are getting, maybe that will suggest what you need to do.

Decided to back up and start again. Setup scope and did a scan of the F75, nice wave and frequency was correct. Then without changing anything on the scope I turned off the F75 and turned on the Deus 2 but this time in the Deus mono program set at default of 17 kHz. Still no good logical wave or frequency. But there are other factors to consider. The coil is also transmitting a radio link to the handheld unit at 2.40 to 2.48 GHz. This would help explain my compound problem of acquiring a good wave. I may need to see if I can block everything above 100kHz. Still working. Played around with the trigger hold off but nothing changed. I'm missing something for sure

Try adding a 1k damping resistor across your pickup coil.

Now the 17 kHz looks better.

General program:
Frequency max 14
Frequency max 24
Frequency max 40

Looks pretty good. Now try to figure out the waveform of the magnetic field.

[Mark-VA]

Before attempting the magnetic field I decided to try the counting function and cursors to determine the exact transmit frequencies. I might not be on tract for the exact reading yet. Thoughts welcome.

[Mark-VA]

My objective is to determine the actual transmit frequencies (multi) of both my Deus 2 and Fred's Manticore. Plus any other that might come my way.
Hold off works fantastic to stabilize the wave to measure. Used the cursor function combined with the counter (marked 1 above)

I have a DS1054 and the inbuilt spectrum analyser sucks ... tho the 1054 is fine unit.

See if you can get hold of PyDSA ( runs on you computer ) ... much nicer spectrum analysis using the 1054 as the front end ADC.

[Mark-VA]

After hours of study I can't seem to measure but 2 different (usable) frequencies being transmitted from the Deus 2. Could I be missing something?
Frequency max 14 and Frequency max 24 are obvious

Frequency max 40 more complex
