The first test done on air was conducted with K5VXT, K5SRZ and K5SL all reports
proved to be of an advantage and a major difference with the amp inline,minor adjustments were made to suit my voice and the
ALC of the radio, the amp can be powered by the radio's mic input 8vdc or
by an external power supply or internal 9V battery.The project took about
one hour to construct and fully functional in about two hours, I hope that you have fun building this project....Good Luck...73
