I have been licensed as WA4KBD for 49 years. WA4KBD is now configured primarily for low power HF digital operation.


My shack...I like this U-shaped desk.  The operating postion is on the left and the workbench is to the right.  Total dimensions are 8 X 8 feet.


Here's the station workbench:


And here's the current operating postion configuration:


It's good to have clear access to the back of the radio gear.  Very much welcome : )

Here's the coaxial entry point into the shack.  It's a metal wall plate drilled
out for three coaxial jacks, making connections and disconnections pretty
much of a snap:

Shown below is how I bring the coaxial cable into the shack.  It's 2" PVC plumbing through a hole in the wall.  The BNC cabling is  a short run up the wall to a GPS antenna for the Trimble Thunderbolt GPS station time and frequency standard.

Here's my little GPS antenna magnetically mounted to the eve of the roof utilizing a steel bracket:

And here's the Trimble Thunderbolt GPS disciplined 10 mhz / 1 PPS station frequency and time standard to which the above antenna is connected:

I like to experiment with antennas, and have recently built up a dipole design by the former ZS6BKW.  This antenna is a sort of optimized G5RV.   One end is at 60 feet with a gentle slope down to about 30 feet. A description of this antenna can be found by googling ZS6BKW.   It's main advantage is coverage of the 40, 20, 17, 12, 10 and 6 meter bands without a tuner.  Add a wide range tuner, and add nice coverage of 80, 30 and 15 meters.





The feedpoint is shown below, along with an RF choke wrapped around 4.5 inch outside diamter PVC. 




 Though a little unconventional, I support my G7FEK with 1.5 inch inside diameter conduit tensioned for vertical stabilty by the antenna wires themselves plus one dacron rope guy for the conduit at the far end of the antenna:



Finally, I enjoy copying NOAA's low earth orbit weathersat passes.  My system employes the Hamtronics R-139 weathersat receiver connected to an appropriate antenna with preamp for 137 MHz as shown below.

Thanks.  I hope you've enjoyed this brief tour of my station.
