1. RAC Affiliated Club Insurance Program: Applications Now Open for 2020

RAC runs the RAC Affiliated Club Insurance Program each year to provide Canadian Amateur Radio
clubs with liability insurance coverage at rates well below standard commercial coverage packages.
In addition, all RAC members who are also members of participating clubs will see the liability
coverage extended, automatically and at no charge, to their own individual Amateur Radio activities.

More information about the RAC Affiliated Club Insurance Program – including details of coverage,
fee calculations and a step-by-step description of the application process for new clubs can be
found on the RAC website at:
If you or a member of your club have any further questions about the insurance program, please feel
free to contact the RAC Office for assistance. Thank you!

3. AO-7 to enter full illumination period October 9, 2019

On or about October 9, AO-7 will enter a period of full illumination that will last until approximately December 2.
During this time, the satellite's onboard timer should switch it between Mode A (145 MHz uplink / 29 MHz downlink)
and Mode B (432 MHz uplink / 145 MHz downlink) every 24 hours.
To check or report the satellite's current mode, please see the AMSAT Live OSCAR Satellite Status Page at
Reporting observations during the first few days of the full illumination period will be helpful for determining
the approximate time of the daily mode change.
Historical information on AO-7's systems, can be found in the AMSAT-OSCAR 7 Technical Operations Plan And
Experimenter's Guide, available at

Additional frequency details are also posted at:

4. Coaxial cables summary

All radio amateurs use coax and often quite a bit of it. Not only is it used for connecting between units in the shack,
but it is also used as the feeder of choice for taking the transmitter power to the antenna and conversely
the received signals from the antenna to the receiver.
The performance of the feeder is crucial to the overall performance of the station. Even a modest run of cable can see
losses of 3dB and more dependent upon the length, frequency and the performance of the coax.
Understanding the key aspects of coaxial cable as well as hints and tips for its use can ensure that the optimum
choice is made for the coax, it is used in the best way, and also installed in such a way that it lasts as long as possible.
