Mobile transmitter finding event
This will be a mobile only event with no walking (portable) portion. We are excited to be able to offer this activity to encourage everyone to get out for some fresh air and look forward to your participation and some discussion about your strategy and success.
Updates and details will be posted here. Please subscribe to the ARDF Ottawa Mailing List for email updates!
Who can participate
Any member of any local Amateur Radio club. Because the participants do NOT need to transmit, anyone with appropriate receiving equipment can participate, whether they are a licensed amateur or not.
What to listen for
The fox will be transmitting on 147.57 MHz @ 0.5 watt. It will transmit a warble tone followed by a Morse code identifier for 15 seconds, followed by 15 seconds off (no carrier) before it repeats the cycle. Be sure to turn your squelch all the way down so you can hear the fox at the edge of its range.
Registration not required
Since there will be no social gathering, you donít have to register or check in. However, we would really appreciate if you would send us an email to let us know that you are participating and to get some sense of the level of interest. Send email to Roger at email@example.com with the Subject set to "March Transmitter Hunt"
What you will need
You will need a directional antenna and (ideally) an offset attenuator so the strong signal will not de-sense your receiver. Hint: Try taking two or more bearings from different points in the city. Draw direction lines on a map to identify the point of intersection. It should be close to the fox.
If you are in a vehicle, please take care to park it in a safe place before you use your radio gear to get a bearing.
Report your findings
Please let us know when you think you have found the fox by emailing the closest street intersection or civic address to firstname.lastname@example.org with the Subject set to "March Transmitter Hunt". Roger will confirm whether you are correct (or not) each evening after 6:00 PM so you can head out again if your answer is not correct.
We would also appreciate if you would let us know:
If you want to participate but donít have appropriate equipment, we have a few portable Sniffers and antennas available to borrow for the weekend if you are a member of either OARC or OVMRC. Send email to to email@example.com with the Subject set to "Borrow Fox Hunt Sniffer and Antenna". Include your Name, Callsign, which club you are a member of and your phone number.
If you can't attend ...
We plan to do one event a month thru September 2021.
