  • Digital Communications

    A great number of exciting new digital operating modes have developed, largely because of the availability of personal computers, soundcards, and advanced software. But amateur digital communication began in earnest in the late 1940's (if you don't count Morse as a digital mode!) when hams worked out techniques of connecting mechanical Teletype keyboard/printers to amateur gear using FSK and AFSK modulation. WSJT has become a very popular tool for digital communications. FSK441 mode is in use for meteor scatter contacts and JT65 is popular for terrestrial communications.

  • EME Moonbounce

    Amateur radio (ham) operators utilize EME for two-way communications. EME presents significant challenges to amateur operators interested in working weak signal communications. Currently, EME provides the longest communications path any two stations on Earth can utilize for bi-directional communications. Amateur operations use VHF, UHF and microwave frequencies. All amateur frequency bands from 50 MHz to 47 GHz have been used successfully, but most EME communications are on the 2 meter, 70-centimeter, or 23-centimeter bands. Common modulation modes utilized by amateurs are continuous wave with Morse Code, digital (JT65) and when the link budgets allow, voice..

  • Aurora and Solar Weather

    The interaction between Earth's magnetic field and Solar particles is a complex and mysterious field of science. The storm events involve high electric currents in the ionosphere and vast amounts electric power affecting to great many things. One of the ways to observe what is happening up there, is to detect the effects of these phenomena to non ionizing long wave electromagnetic radiation - radio waves.

  • VHF Contesting and Rover Operations

    Hams have been putting stations in their cars since the Twenties (1920's that is). Today, there is great satisfaction in facing the challenge of installing a transceiver in our small cars and pick-ups, using somewhat inefficient antennas, and still being able to make contacts with hams thousands of miles away while "tooling" down the highway.

  • Annual Technical Conference

    Every year since 1968, during the last weekend in July, the Central States VHF Society hosts an annual technical conference. There are two days of technical presentations, antenna range gain measurements, noise figure measurements, a flea market, and often times a vendor area. It's a great time to learn about weak signal VHF communications and an excellent place to network and catch up with old friends.

Exploring the World Above 50MHz since 1965

States Above 50MHz

States Above 50 MHz Award                                                                        (updated 5 July 16 by W9FZ)


1.  Promote interest in VHF/UHF operating and in The Central States VHF Society by issuing certificates to anyone working 30 or more states/provinces, in a one year period, onthe bands above 50 MHz.

2.  Promote activity across all bands above 50 MHz and all propagation modes found on these bands.

3.  Promote working States/Provinces as this was the original goal of the founding amateurs of the CSVHF Society.

4.  Promote membership in the CSVHF Society - only members are eligible for the 1st, 2nd, and 3rd place plaques.

Contest Period:

0001 UTC, 1 July YYYY to 2359 UTC 30 June YYYY.


Work as many states and provinces as possible on each of the amateur bands above 50 MHz.

States Above 50 MHz Award Information


If you grabbed the Excel file before afternoon of July 9th, you'll find that the dates on the individual band tabs display as "xxxxxxxxx's".  This new file is unprotected and has the date columns widened slightly to avoid "xxxxxxx's". There are no macros intended in the file so you can disable macros when "warned".

This last file is in MS excel format and includes a summary tab and tabs for each band. You should be able to "save" the file to your computer and use it throughout the year. Rename the file with your callsign and you can submit just that file (as one option). (If you just click the link, it opens as a "read-only" spreadsheet. You'll need to save it to your computer to be an editable document for you.) 


Notes:  Populate the "Summary" tab with your Call and 2-letter state and those will propagate to all the remaining tabs. Change the program year on the Summary tab for future years. The date column will take just about anything you type and convert it to a fixed format of date. (mm/dd/yy is the quickest.) When you fill in the columns for callsign, time, date, and mode, you'll get a "1" in the count column.  It does not increment. You can just leave it or feel free to change it to a running count on that band. Either way, the summary sheet counts the states and keeps a running count. Just email the file for electronic submission. It's best if the filename indicates your callsign and the program year.  You can also save to a .pdf or print to a .pdf depending on which version of Excel you are using.
