Minutes - YRARC General Meeting 2018-01-02

Meeting held in the Sharon Temperance Hall. Called to Order at 19:30 by Chris VE3NRT. Total members and guests attending: 26
  1. Welcome & Introductions: Chris VE3NRT
  2. Adoption of minutes from 2017/12/05. Postponed until February 2018.
  3. Repeater Committee: Steve VE3UT
    • The voice IDs on the repeaters are now muted when the repeater is in use. VE3YRK-V is still off the air due to a 4:1 SWR.
    • Winter field day will be on January 27 and 28, and we will be at Al's Tack Shop on Vandorf Rd. A show of hands indicated approximately 10 people plan to attend. The cost of fuel and snacks will be covered by the club. Peter VE3PBT will prepare a light meal for those wishing to stay for supper at a cost of $3 per person.
  4. Don VE3IXJ noted that VE3BAL is now on a new frequency.

Break: 19:50

Guest Speaker: Don VE3IXJ
Topic: The Power of the HT Repeater.

Don demonstrated a simplex repeater, Surecom SR-112, costing approximately $80 Cdn bought on eBay from China. It attaches to the mic/speaker of the HT radio. On receive it records the audio, then re-transmits the recorded audio. It is a very simple solution for use in a local environment. Then Don demonstrated a crossband repeater, Surecom SR-628, costing approximately $90Cdn. The lightweight and inexpensive repeater could be set up easily and quickly in a typical emergency where simplex operation might be ineffective.

The crossband repeater was connected to an inexpensive Chinese radio capable of crossband. Anything received on VHF was retransmitted on UHF, and anything received on UHF was retransmitted on VHF. To extend the range, Don added a second crossband repeater/radio combination and then a third repeater/radio combination. From end to end a typical path would be VHF Freq#1 – repeater – UHF Freq#2 – repeater – VHF Freq#3 – repeater – UHF Freq#4.

A conversation could be heard on any frequency along the path. A radio in the middle could transmit on UHF Freq#2 or VHF Freq#3 and be heard at both ends of the path on VHF Freq#1 and UHF Freq#4.

YRARC General Meeting - Minutes 2017-12-05

Meeting held in the Sharon Temperance Hall. Called to Order at 19:30 by Chris VE3NRT. Total members and guests attending: 27
  1. Welcome & Introductions: Chris VE3NRT
  2. Adoption of minutes from 2017/11/07. Moved Rick VA3VO, seconded Jack VA3UU. Carried
  3. Ontario VHF Association: Bob VE3WY; The Ontario VHF Association is having a 1 day meeting in June, with antenna testing in the morning, and technical talks in the afternoon, followed by dinner. Bob asked if we as a club would host the event.
  4. ARES Report: Mike VA3MCT; The recent SET in Markham was based on a 5 day power outage. Messages were passed using only simplex communication, however hand written messages using standard voice relaying are slow, and not the way to go forward. Eric VE3EB and others are experimenting with Fldigi to transfer messages of UHF and HF. Steve VE3UT and others have tested D-Star to transfer messages. John VE3IPS would also like to encourage the use of NVIS antennae for short range HF links.
  5. Treasurer’s Report: Charles VA3TTB; There was no working projector and no definite treasurers report, just figures from memory. Charles spoke about a proposed project night Arduino antenna analyzer. He has been sourcing parts for the project, and the cost should be approximately $100.
  6. Repeater, Winter Field Day Reports: Steve VE3UT; The D-Star VHF repeater is off the air until further notice. The antenna has a 4:1 VSWR. Steve asked for a headcount of potential WFD participants, to estimate refreshment requirements (approximately 10 to 12). Proposed bands for operation will be 160m, 80m, 40m and 20m...Phone, CW and digital modes. Rob VE3RQB wanted to know when the 'brag messages' on the repeaters would be lowered when there was a conversation in progress.
  7. Public Service Report: Eric VE3EB; There are still items remaining from the estate of Bernie VE3OTR. John VE3POJ is disposing of the assets. Contact Eric for details.
  8. Hamfest Report: Geoff VA3GS; Geoff thanked all who were involved with the Hamfest. He also noted that as of December 1, all cell phones can be unlocked without charge for the unlock code.
  9. Membership Report: Barry VA3LLT; We have a total of 70 paid members including life members.
  10. Name Tags: Doug VE3VS;Anyone a name tag, please contact Doug. When there are enough orders, the name tags can be made. There is a DXpedition at the Galapagos Islands, and Doug received his Vimy 100 certificate.

Meeting adjourned at 20:15. Moved Rick VA3VO, seconded Jack VA3UU. Carried.

The Christmas party followed the business meeting.
