AWA 6AQ5 Transmitter (continued)

 I've gotten the power supply built into my 6AQ5 transmitter. I used an old school PS design: a 6X4 full wave rectifier with a capacitor input filter feeding a 20K bleeder resistor. 

This transmitter is working and sounding fine. Power out maxes out around 6 watts with 15 watts input....a couple of items I can look at 1) calibration of my watt meter 2) the value of my pi network coil. Compared to 8 to 9 watts out 6 is not a big deal. I'll poke around at this issue later 

For now I'm pairing this transmitter with my hopped up National NC57. See https://w0vlz.blogspot.com/search/label/NC-57  .


**** Addendum **** 

Tonight I worked Don , N0DLR, using my NC57/6AQ5 station.  Even with a lot of static we had a successful QSO. The Reverse Beacon Network reported many hits in the North East US with a few more scattered to the south and west of me. My new rig is in the log.
