  • 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.

Reverse VUCC

Reverse VUCC Award Program

Purpose:

This program is to recognize the contribution of rover station operators to the world of grid hunting. Rovers are folks operating while mobile in motion or temporarily parked to give out grids to fixed stations.

VUCCr Honor Roll

Discussion:

Fixed station operators have long appreciated the efforts to which Rovers go to activate rare grids--both in contests and outside of contests. While the fixed station operator is collecting grids usable for earning the ARRL's VUCC award, the rover or portable station, until now, has been unable to put his work towards a similar award.

The award is called the Reverse VUCC Award. The abbreviation is VUCC/r. It is not an easy award to earn. Those who can meet it's stringent rules will have earned a cherished honor. For instance, imagine a fixed station collecting grids on 10GHz. If one Rover is the station who activates the appropriate number of grids for him, each operator made identical contacts but who worked harder? The Rover--it is that effort which the CSVHFS wants to recognize and honor.

The award is very similar to the ARRL's VUCC, but rather than contact a set number of grids on a frequency band, the goal is to make contacts FROM a set number of grids per band. The number of grids coincides with the ARRL award. Certificates will be awarded as well as endorsement stickers. QSL cards are required and will be verified by the program administrator. Awards will be presented with a unique serial number. There is no fee except return postage must be included (for the QSL cards).

The award comes into fruition due to the efforts of Bill Wageman, K5MAT, who is the program administrator. Rules and contact information will always be available on the CSVHFS website at www.csvhfs.org . Rovers and portables, take a look at the rules, initiate cards from all those QSO's from your past, and submit entries for this significant award.

Rules:

Contacts made on January 1, 1983 or later qualify. The rules that govern the ARRL VUCC program are also applicable to VUCC/r with the following exceptions and qualifications:

1.  All contacts must be made operating while away from the home station location.

2.  2. The applicant must work and confirm contacts made while activating different grids. Which grid or grids the rover contacts is not relevant except for contacts above 1.3 GHz per Rule 3. Confirmation can be QSL cards, QSO listings, or log extracts.

2a.  Required information: QSL Cards, QSO listings, and log extracts must include both calls, both grids, mode, date, time, and band/frequency. The QSLing stations fixed info such as callsign and grid need not be on every line of a QSO listing, or log extract but must be indicated somewhere on the page. Required information may be in any order on a QSO listing or log extract. Cards, listings, and extracts should additionally have the name of the licensee (person or club); mailing address; operating location information if different from mailing address (address, GPS coordinates, 6-digit grid, or Lat/Lon); and have a written signature (minimum of first name) of the licensee, trustee, operator, QSL Manager or appropriate person confirming the specifics of the listed contacts. If a QSL card does not natively indicate the grid in which the rover was operating, it should be added in pencil.

2b.  QSL cards, QSO listings, or log extracts may be submitted indicating contacts beyond the number required for an award or endorsement level. The program administrator will maintain record of these additional QSOs. Subsequent submissions should refer to QSOs on file when applying for an endorsement.

QSO Listing Example

3.  At frequencies below 1.3 GHz (and Satellite) any number of stations in any number of grids may be worked. Above that frequency target stations worked must all be within the 300 meter circle that is specified by VUCC rules. The location of the target stations must be indicated on their cards by at least the four digit grid, or preferably their lat/lon or some other indication that they were inside the same circle. The rover, of course, is obviously required to move around.  This rule was deleted by the awards committee with BOD approval on 7/25/2015.

4.  Endorsements above the basic award may be submitted just as in VUCC.

5.  The only report form needed is a readable alphabetized list of the grids from which operation was done with the calls of the station worked. The applicants call and name must be clearly stated.

6.  All cards and forms, along with appropriate self-addressed packaging with sufficient postage for the return of the cards plus a business size envelope (if folding the certificate is OK) or 9" by 12" or larger SASE should be sent to:
