Is this still a demo or a Full hex master ORBIT?
(I always dream to have a full hex of my Delta Pulse 2)

they have 'spring festival' (chinese new year?). thinking there may be a delay.

Ahh so that's the "Delta" in Delta Pulse!
Sorry I haven't read the whole 98 pages of this thread.
I looked for a description of this MD but didn't find anything.
With all the info on this site it is sometimes surprising what's
missing or difficult to find...

had answered many times... something like a protection from overloading of amp part, on big target near coil. working such way. if a signal gains to some level this circuit turns on and moves out primary sample pulse in a range with more low amplitude - ie at right side of 'delta' pulse.

Hey Guys I often wondered what the circuit framed in yellow does in this design?

Modify pulse width based on ground loading? Anyone know?

I do not know exactly.
I learned that when a large metal, coil to approaches increases the delay, possibly to avoid overload.
In a modified DP for coins (decrease delay and increase in frequency), disconnect the collector VT2, to bypass this circuit.
By this I get softer the "delay" setting.

GOOD EVENING TO ALL..
I changed the diode sttf1210 with byv28-200, The result is that the voltage reaches up and its 240 voltage While the diode stth1210 in 210 voltage.the byv28-200 has a smaller REVERSE RECOVERY TIME (trr) the value of is 30ns...
This can be an advantage what is your opinion..

Thank you kt315 to answer YOUR..
MERRY CHRISTMAS

I remember this mod, have checked it... did not see something specific in stability increasing.

Wasnt there a mod that added a 10k R between T3 and -Bat

да вижу ... что р5 надо настроить .....но как правиль ето делать? на пример ... у меня катушка .. 40 диаметр и 3.7ом 0.550мхенр. .... поставил р5 от 500ом до 2к .... и чуика одинаково .. картина номер1 уменя с 500ом а картина номер2 с 1.8
