Slim Jim Antenna Project UPDATE

This just in from Barry Allison (VE3NA):

The original instructions for the Slim Jim 2 metre antenna gave dimensions that were in error due to calculations based on an incorrect value for the velocity factor of the 300 ohm twin lead given by the cable vendor. Folks that received and already built their kits based on the previous instructions will be given a replacement length of 300 ohm cable to correct the problem that resulted in a high SWR.

The Slim Jim Antenna kits are now available for all that signed up, at a price of $25.  Contact Barry Allison (VE3NA).

Barry will have the kits available at the OVMRC Christmas DInner.

IARU Region 2 Bandplan

As part of the XIX IARU Region 2 General Assembly in Viña del Mar, Chile, a new Band Plan for Region 2 was approved on October 14, 2016 during.  The document is published on the IARU Region 2 website in English and Spanish.

The changes aimed at harmonization with Regions 1 and 3, recognizance of some band occupations in Region 2 and the contextualization of the satellite segments to encourage the use of new technologies in space communications.

The main modifications are:

  • Introduction of the 60 m allocation with sub-bands, footnotes and definitions harmonized with Region 1;
  • The inclusion of ACDS in 2200 m, restriction of bandwidth in 630 m, harmonization of the 160 m and 80 m, especially on digital sub-bands;
  • Recognition of the calling frequency 144.3 MHz in 2 m and AM practice in 15 m;
  • Editorial changes in the footnotes related to ACDS, additional footnotes related to AM and editorial changes in some of the footnotes, modes and bandwidths of satellites sub-bands.

The Band Plan does not have an enforcement power per se but serves as a guide to the Member Societies. According the IARU Region 2 Band Plan “it is suggested that Member Societies, in coordination with the authorities, incorporate it [the Band Plan] in their regulations and promote widely with their amateur radio communities”.

RAC was represented at the meetings in Chile by Glenn MacDonnel VE3XRA.

June 2016 Fox (Transmitter) Hunt

The OVMRC will host a radio direction finding exercise / transmitter hunt (i.e. fox or bunny hunt) on Saturday, 4 June 2016, at Petrie Island in Orléans, at the north end of Trim Road.  Start time is 11 AM, and the event is expected to run until 2 PM.

Everyone – members, family, friends – is invited.  There is space to picnic and to hunt the transmitters.  Those who wish to join us are to meet at the picnic tables near the parking lot.

Bring your own picnic lunch and refreshments.

There will be a talk-in on the VE3MPC repeater, 147.150+

Please contact Norm (VE3LC) by email (link will open your mail program) to let him know if you are planning to attend and how many in your group.  If that link does not work, you can also contact the webmaster with your information.

Full Details of the Transmitter Hunt:

Entrants can work individually or in two or three person teams.

To locate both (two), 2 metre, low power beacon transmitters that will be hidden on the grounds of Petrie Island within reasonable short hiking distance from the starting point. Each of the two transmitters will be transmitting on different frequencies.

Ideally, directional antennas will assist in finding the transmitters however, it may be possible to find the transmitters using nothing more that a conventional 2 meter FM handheld portable with standard antenna. The transmitters will be transmitting a steady CW carrier signal with an occasional Morse ID. Frequencies of the beacon transmitters will be provided at the site.

The two transmitters will likely be hidden in opposing directions so two individuals or teams can depart from the starting point at the same time seeking one or the other transmitter. After finding the transmitter and marking the sign-in sheet where the transmitter is located or after 30 minutes (which ever comes first) the individual or team will promptly return to the starting point to be sent off to try to find the second hidden transmitter. A longer time than 30 minutes may be given to try to find the transmitters depending on how many participants there are for the event.

Participant will be requested to have a dedicated second portable tuned to 146.52 to listen for instructions to return to the event control when time limit is up. Radios will be on hand for folks without a second radio.

73 and we hope to see you there!
