Welcome to
the
station of
W8KHZ
Traverse City, MI
Here are a few of
the radios at the W8KHZ Shack!

Here I sit in front of the "big rig"
here at W8KHZ - my homebrew transmitter consisting of a pair of 250THs
modulated by a pair of 810s. I use the Viking II transmitter to the right to
drive the push-pull 250THs in the final and the little Masco speech amp on the
shelf to drive the 810s in the modulator. The 250TH transmitter is paired up
with an EAC R390A with CV-591 SSB adapter, just behind me in the picture.

Here is a picture of the the other side of the the
hamshack showing some other goodies including several receivers. Pictured here
is a beautiful Hallicrafters SX-28, SX-42, a National HRO-50T, and a
Hammarlund SP-600 (on the floor). To the right is my other "big
rig", a BC-610-I Transmitter that I purchased from Roy - W9QM in Aug,
2003. Weighing in excess of 400 lbs and capable of near legal limit on AM,
this transmitter is a real tank! It is currently paired up with the HRO-50T
receiver and it is a real pleasure to operate!

Another shot of the BC-610-I. This particular
transmitter was built in 1952 during the Korean War. More than 50 years
later it is still doing battle - on 75 meters!!

Front view of the homebrew 250TH
transmitter. Nearly 6 1/2 feet of big triodes, heavy iron and high voltage! Its
been rattling the ionosphere for over a year now!

Rear view of the homebrew
250TH transmitter. The bottom deck is the 2500 volt plate supply for the
Class C final amplifier. The second deck from the bottom is the 1750 volt
plate supply for the modulator. The third deck from the bottom is the 810
modulator. The copper colored section at the top is the Class C power
amplifier.

Close up view of the rear of the
Class C amplifier. Classic 1940s - 1950s design - push-pull 250TH triodes,
B&W HDVL tank coil, B&W butterfly capacitor and link coupled output!!
