Dr. Greg Latta's
Electrical Engineering
and
Amateur Radio PagesWelcome to my electrical engineering and
amateur radio pages. These pages will, of course, change as time
g
on so I encourage you to stop back every so often.
My latest project is the 6x2 Superheterodyne Receiver. This is a
6 tube superhet receiver forthe 80 m and 40
bands. It features a crystal filter for single signal CW
reception, a crystal calibrator, and the ability to receive
WWV at 5 MHz. The I am currently working on integrating the
receiver with the Wingfoot VFO Exciter/
Wingfoot 813 Amplifiertransmitting system.
The 6AG7 Class A VFO Amplifiercan be driven by an analog or
digital VFO and can be runby itself as a 3
watt QRP transmitter or drive the 6146B Amplifierto 60 watts of
output on the 80 m - 20 m bands. For crys
control, the 6CL6 One-Tube Transmittercanbe used instead ofthe
6AG7 VFO Amplifier.
The 1955 Wingfoot VFO Exciterand modern Wingfoot 813
Amplifierform a complete, late 1950s/early 196
high power, all tube, VFO transmitting system. The Wingfoot VFO
Excitercan run barefoot at 27 watts outpu
or drivethe Wingfoot 813 Amplifierto 250 watts output on the 80
m - 20 m bands.
When I added a new Ameritron AL-572 amplifier to my shack (which
I love), I also also purchased the QSK
5PCcircuit board for break-in CW. I spent considerable time
studying the QSK-5PC on the workbench to
understand how it worked, and put everything I learned here on
the web under Electronic T/R Switching and
Ameritron QSK-5. Anyone interested in how electronic T/R
switching is done will find Electronic T/R Switchi
and Ameritron QSK-5quite useful.
Pages are also available on a fascinating study of secondary
emission and emission saturation in vacuum tubes
These pages are the result of work done by Frostburg State
Universityhonor student Angela Meyers for her
honors thesis. An information page for students at Frostburg
State Universitytaking Physics 340,
Audio Engineering, has also been added.
