Did you hear a callsign you want to look up?
QRZ callsign lookup:
"Grey-Line" propagation happens at sun-up and again at sun-down.
Your signal will go significantly farther along the grey-line between day and night. This map shows where the grey-line is right now. Check this at sun-up and again at sun-down to see where your signal will go.
The shadow moves to the left.

The WC7I website contains lots of stuff that is not organized into one subject so

there are several options below for you to choose.

Antenna Fundamentals begin here.

  • Dipole element and radial length calculator.. You pick the frequency of operation, and I will calculate the element and radial length. First dipole? Start here.

  • Aiming a dipole antenna. This works for aiming any antenna.

  • 3 Element Yagi antenna design for any frequency.. You pick the frequency of operation. This is why you are here!

  • Vertical Antenna Theory (using buried radials). You need a lot of information to understand a Vertical Antenna. Or, maybe this is why you are here.

  • SWR and Antenna Tuner theory (the truth) The real honest information about what happens in the antenna system with a high SWR

  • Everything else I do not have here.
    This is the K6XC Ham Radio Web page. It has lots of links for everything you ever wanted to know. Press your "back" button to come back here.

    • ↓ The rest of the site information is below. ↓

  • The WC7I repeater information.. Lots of WC7I repeater details.

  • OOPS.....The following TWO sites are not working, They claim they will be back soon.

  • H. F. band DX usage.. You can see the band activity in the last 24 hours and in the last 30 days. Both Tim NN4DX and Ron NN5DX have a fantastic system of reporting where the DX is right now. Press your "back" button to come back here.

  • H. F. band DX usage.. Sometimes this is "up to the minute" information for each band. Often the one hour table has information. Be sure to click on the band + time column to find out what the DX stations are doing. Click on "SPOTTER" and on "DX" to get everything that QRZ has on them.
