Some good advice from several people. My advice would basically be a recap of theirs, but I do have a question for everyone.
My local club has a long standing rule against flying on any channel that is within two channels of one that is in use. I used to be a radio technician in the service, so I understand the reason behind this rule, and since the club is relatively small (around 30 members) it doesn't create a big problem, but I was wondering if it's really necessary with today's narrow-band radio gear. I know that years ago, radios had a good deal of "drift" so you could actually be on one channel, but be "dirtying up" the channel above and/or below you. Just curious...
