i have gotten better performance with the cap
I am nowhere near tech level!!!
I just copied this from CBTRICKS Mosfet Experimentals Info Notes for EKL Mosfets. NOTE THE BOLD THAT I ADDED TO HIGHLIGHT ONLY!!! Maybe it depends on the rig?
Schematic of the EKL ENXXX's
The following was posted on the forum from a member of the site.
Just for the record I thought I'd try the single mosfet in a DX33HML using the directions provided.
In all honesty I have to admit it worked rather well.
I posted some wattage readings below with notes.
2SC1969:
25.615 - deadkey = 8.5 watts - 28 watts peak
26.965 - deadkey = 9.0 watts - 31 watts peak
27.865 - deadkey = 9.0 watts - 30 watts peak
ERF2030:
25.615 - deadkey = 8.3 watts - 38 watts peak
26.965 - deadkey = 9.5 watts - 43 watts peak
27.865 - deadkey = 9.4 watts - 40 watts peak
Notes:
Peak power readings on IFR1200 Communications test set.
No modulation limiters removed.
Full modulation with no flat topping.
Current draw same on both devices.
68pf cap not recommend (causes less output)
Do not remove L33 slug (required to balance power on upper and lower bands.)
ERF2030 has slight impedance mismatch on the output. (not bad)
Like I said, I am not a tech. I am a starter ONLY! I am researching.. BASICALLY STANDING ON THE SHOULDERS OF GENIUSES, TO GET A BETTER VIEW! BEFORE BLOWING MY STUFF UP!!!
