Paul KocylaDone some frequency sweeps between 22.0 GHz and 25.6 GHz and recorded the RX power, current and force in order to find some clues for the resonance frequency.
I did it first without antenna and then with an omnidirectional antenna and finally with the cavity (with tuning screw and with fixed endplates)
There is something happening around 24.6 GHz in the RX graph (600s sweep) which comes together with a force change (fixed endplate cavity) - but I need to check it in detail before I post some information based just on assumptions.
I wanted to release the software for viewing the data today, but it has still a bug in the display for recordings longer than 480 seconds, so I´ll fix this first before I release it.
Don´t worry, it won´t take long.

im working on a redesign of the cavity unit (i place the magnetron on top of the cavity, in stead of feeding it sideways..) I still believe that this location is better than feeding the waves indirect. the cavities in the magnetron itself pushes the waves out of the small gaps, downwards so the repell forcing effect MUST be stronger (Lorentz force) . i will send you a rendering asap.
Are you sure? yes | no
