Frequency control at your club
SDR,
We only have one Ham band flier at our field, so I didn't make pins for them. However, it would be a very good idea to include them.
We very seldom have multiple flier conflicts, as we only have 45 members and of those only maybe 15 regular fliers.
We recently had 2 that were on the same channel and one of them switched to a channel that no one had been using while they were at the field.
