The original Class E rig "Einstein"


this is the first attempt at solid state based on Steve WA1QIX's class B series modulator...

4 FETs on the left put out 250 watts carrier!


Here is a close-up of the audio section, note the black heat sink (IRF610) and the voltage regulator behind it have all been removed from the new class H modulator


Here is the brute force power supply that delivers the 100 and 50 volts to the modulator. It is a bit overkill and plans are being made to downsize it.


High Voltage!! (yea right... what do you think this is? a tube rig?)


Here is the whole system, transmitter and power supply ready to put out a strapping signal!
