I don't know if the power supply come from the same XFMR or not but what does "10 on the knob" mean?

For my Ranger / amp situation, I originally looked at doing exactly this. I have a couple of reservations - first is that the LV Supply will have to stand the additonal load over the long haul, and second that I'd really rather the mod section be running at "10 on the knob". Also, the resistor, if variable (even the 'slider' type) allows one to adjust the output as needs be - I want to run RTTY which is even more severe than AM in terms of overall duty cycle , and I want to spare my old amp (an Ameritron AL-80) as much as possible. Then again, I have the schematics for the "attenuator" as Johnson called it - to go between the Ranger output and linear input. And of course there a lots of topologies that will accomplish the task of lowering the output of a tetrode or beam-power RF section without upsetting the relative current balances. Mebbe I oughta should by a junker Ranger... Just In Case... ;} Cheers John KB6SCO ______________________________________________________________ AMRadio mailing list Home: http://mailman.qth.net/mailman/listinfo/amradio Help: http://mailman.qth.net/mmfaq.html Post: mailto:[email protected] AMfone Website: http://www.amfone.net AM List Admin: Brian Sherrod/w5ami
