Hi Roger, Am 30.09.2010 20:26, schrieb Roger Lapthorn: I really must make a serious attempt to raise my ERP though as the current level is just not enough to give most people a fighting chance of copying me. Good idea ;-) Change the IRF510 in the class E by a IRFP460 and increase the voltage to 100 VDC. Compared to 12 V, this will give ~ 64x the power, so 18 dB :-) 73, Stefan |
