Frequencies Used by the KMSC

All radio control equipment used by KMSC club members must be legal for this use in accordance with FCC rules. Model airplane radios are assigned to the 72 MHz band and IAW with FCC regulations may not be used to control model boats.

If you are planning to buy a sailboat and sail with the KMSC, please examine this page and choose a band and frequency that is not assigned. Two boats cannot operate on the same channel at the same time. Only the Spectrum Radio will automatically choose open channels when it is turned on.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

No KMSC radios are operating on the 49 Mhz band where some low-cost boats and cars operate

No KMSC radios presently using Amateur Radio bands

No KMSC radios presently using 27 MHz band

KMSC boats on 75 MHz Band

30 channels in the 75 MHz band are assigned by the FCC to "ground" control use, meaning "not model aircraft". So these channels are used by RC cars, boats, and robots. Care should be exercised if model cars appear at the park while sailing, since they may be on one of the channels we are using.

When ordering a new radio, skippers should avoid assigned channels and those marked Do Not Use. Please choose any channel with a "-" in the "Assignment and Use Notes" box--the ones that are white in the first column.

If a club member gets a new radio on one of the channels already assigned or restricted from use because of 3IM, it becomes their responsibility to obtain a crystal set on a different frequency that is not permanently assigned. It would be nice to reserve the frequencies of the "inactive" skippers so they can come back and join us at any time. However, if you are joining the club with a V-32 and already have a radio on one of the tan shaded channels, please call the Commodore, and most likely that channel can be assigned to you.. V-32 channel assignments will be given priority.

They say the loser learns more than the winner. After that last regatta, I sure must know a lot.
