Charlie Justinak, W7GBI, started building this AM rig a year or two  before he passed away on Feb. 12, 2008.  I purchased the various chassis and parts from his estate to continue with the construction.  It pained me to think of Charlie's work being "parted-out" on E-Bay, or worse, making a one-way trip to the landfill.

The rig runs a pair of 813's in the final, modulated by a pair of triode-connected 813's, and is based on the K1JJ design.  Charlie originally planned for the transmitter to cover 160 and 80 meters.  However, I plan to extend that coverage to 40 if at all possible.  The rf and audio drive will be provided by a Johnson Ranger II that Charlie procured for the purpose.

The most incomplete part of the rig is the power supply.  There are several options available.  One is to use an existing chassis (pictured) that contains a fairly hefty transformer that supplies 2000 VAC CT with a full-wave bridge.  The other is to start from scratch with what I call the 'submarine transformer' that is rated at 1470 VAC @ 1.2 amps in a capacitor-only filter setup.

More notes to come later....
