PICTURES & MORE

As is true with most Hams, I have many other interests.  I will post pictures, photography is another of my hobbies, here and miscellaneous other distractions. 

The Star Trek symbol on here was photographed from a lamp made from sheet metal with holes drilled thru.  The sheet metal is rolled into a tube with a blue CFL lamp on the inside.  I then modified the  shot in Photoshop and this is the result..  Next to it is a picture of the actual lamp.  It was purchased from a gentalman at the Plymouth/Canton art fair.  He makes all kinds of designs including sports teams and other "cult" designs.  The workman ship is very good.

Pens Made

My 1st Magnetic Loop
Below are pictures of my first Magnetic Loop Antenna.  Living in a condo I'm not able to put antennas outside.  Also since I've had my right leg amputated, I'm not able to easily get up into my atic area.  This has challanged me to come up with antennas that work inside my condo.  Fortunately I have two floors so I can place units on the second floor.  My main antenna is a 300 ohm twin lead at 66 foot in length that snakes around the condo just underneat the ceiling and is fed with a 450 ohm ladder line and tuned with a MFJ-969 tuner.  This wire just does not make it on 20 meters so my quest for someting that does and at this time it is the mag loop.  After I'm done experimenting, I'll build my final antenna.

You can see some of the 300 ohm twinlead in the upper right side of the picture.

    The loop is tuned via the double gang variable capacitor at the top. I picked up this cap at the 1st Great Lakes HamCon at MIS. The cap is a bit beat up but it does work. Excuse the mess on the floor, my shredder blew up.
  2. Magnetic Loop on Tripod
    Magnetic Loop on Tripod
    I decided to try and build this tripod from a picture I saw on the internet. It is constructed from 1 inch PVC and 5/16 threaded rod. It is crude and a lot unstable. It would not do well outside.

    My first Magnetic Loop antenna
    Taking various design methods from the internet, I built a magnetic loop antenna from quarter inch copper tubing and PVC pipe.
  4. More parts
    More parts
    Additional parts for the antenna including the little red feet for the three legs of the tripod and the nuts for the threaded rods for the legs. Also a closer look at the 1 to 3/4 reducer and the threaded to slip fit for the 3/4 pipe.
  5. PVC Parts
    PVC Parts
    This is the collection of PVC parts, 3/4in pipe, 1in pipe, tees, reducer and connector to hold the copper tube and support the structure.
  6. Loop Construction 1
    Loop Construction 1
    The end caps for the tees have a F drilled hole thru the middle of the cap to accept the 1/4 copper pipe. The first cap has been placed on the tube.
  7. Loop Construction 2
    Loop Construction 2
    The tube is put thru the T and the cap is in place on the end of the T
  8. Loop Construction 3

    A continuation of putting the pipe thru the T's and end caps.
  9. Loop Construction 4

    The end caps placed onto the copper pipe at the top of the loop.

    The 14awg wire that is connect with the coax to the transceiver and sits adjacent to the loop. The extra wire on the right was later removed.
  12. Loop Construction 7

    The entire loop assembled.

    End caps for the 3/4 T's with F drilled hole for the 1/4 inch copper tubing.
  15. Driver Loop
    Driver Loop
    Here the driver loop is soldered to the coax. This is 14awg solid wire placed inside a 1/4" od poly tube to keep the wire from losing its shape.
  16. Wire to Main Loop
    Wire to Main Loop
    A wire is soldered onto each end of the tube at the top of the loop. These wire go to the tuning capacitor.
  17. Tuning Capacitor with Coax
    Tuning Capacitor with Coax
    This tuning capacitor is a two stage unit that calculate to about 250pf. It also should be good to 4500volts.
  18. Capacitor Mounted
    Capacitor Mounted
    I mounted the cap to an Oak board so that I could use U-bolts to mount the cap assembly to the PVC just underneath the top of the loop.
  19. Capacitor Wiring Connections
    Capacitor Wiring Connections
    Viewed here are the connections to the stator and rotor connections of the capacitor.
  20. Cap Mounted

    Another view of the tuning capacitor attached to the mounting board.
  21. Tuning Hose
    Tuning Hose
    I used a 1/4id hose with hose clamps to attach to the tuning capacitor and to a knob so that I can tune the antenna. This has been trimmed to a short length awaiting a stepper motor replacement.
  22. Capacitor with Wire

    One of the two connections on the capacitor with a wire attached.
  23. Tuning Capacitor in Position
    Tuning Capacitor in Position
    Here the tuning capacitor is at the top of the loop with both wires attached to the cap and the loop.
I picked up a Heathkit HW-101 Transceiver for a couple hundred dollars.  It's not in too bad shape but does require some work  The pictures are how it looks today.  I'll post the updates as I progress.  I did clean up the rig a bit before I took the pictures.
