Transmitter Locating Exercise

The OVMRC will be staging a transmitter location exercise between 24 and 31 Jan 2018.

The Transmitter

2 metre, 15 mW beacon transmitter, to be hidden somewhere in Central Ottawa.

Frequency Set to: 147. 585 MHz FM with MCW ID

Objective:

To determine and report the address or approximate location of a beacon transmitter.

Method:

By driving around or by using directional antennas with or without triangulation techniques.

When:

The transmitter will be On-Air between Jan 24th to Jan 31st.

Send your findings to Norm at VE3LC@rac.ca; any emails received will be reported at the February 21st meeting of the OVMRC. Certificates will be issued to folks that give the correct location of the hidden beacon transmitter within a radius of 500 metres.

 

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.
