I redid the measurements from yesterday now on video. Ambient temperature at the start is 18.3°C also across the Grenade. Temperature across the Grenade at the end is around 21°C so a slight increase of 2.7°C but probably due to the 10 a 12W being supplied into this coil. Using the pulse amp. from Stalker feeding with the FG with a pulse, 71 - 73% duty cycle and 10Vpp DC, starting around 1.2MHz. I have 12V on the pulse amp. logic from a PS and 12.5V (~1A) from a battery being switched into the exciting coil. Measuring with the HV probe the drain of the MOSFET The Grenade is grounded to house ground with its cold end and open on its hot end. Finding max. LC resonance (around 1.22MHz) with max peak drain signals. Then looking for Wave resonance using the fluorescent lamp rings. They merge around 1.22Mhz, but there also is a strong merge point at 2MHz. Video here: https://youtu.be/KG03TiJXXdENext is to find/test the push pull frequency and lateron the Kacher frequency. Regards Itsu
