Default RE: most used freq chart?

RichD,

I agree with an earlier reply... frequency crowding on particular channels will probably vary greatly from club to club. However, for what it's worth, I have just spent the better part of a year doing a frequency survey for our club. I think I can state one fact unequivocally; something very non-random happens with frequency distribution in a given group of fliers. In our case, I gathered up the channel numbers for about 90 fliers, representing no less than 160 transmitters. ((I'm always amazed when someone gives me 5 or 6 frequencies! Why don't they peddle all those old single-model transmitters for 30 or 40 bucks apiece on eBay, and use the proceeds to buy one modern 6 or 8 model computer Tx?))

Anyway, here are the distribution numbers:

Channels with 1 user: 11, 30, 53, 55, 59, 60
Channels with 2 users: 12, 13, 14, 17, 19, 21, 24, 27, 45, 46, 47
Channels with 3 users: 26, 28, 35, 37, 41, 43, 44, 49, 51, 56
Channels with 4 users: 15, 16, 18, 23, 25, 29, 31, 32, 33, 34, 36, 57, 58
Channels with 5 users: 22, 38, 39, 40, 48, 52, 54
Channels with 6 users: 50
Channels with 7 users: 42

Like I said... obviously, something non-random is happening here, but I don't know who or what to blame. In a perfect world of 160 transmitters and 50 channels, the vast majority of channels would only have 3 users, and a handful with 4. But we've got channels with 5, 6, and even 7 users, and therefore, several with only 1 user; in fact, prior to this campaign, there were 2 or 3 channels with NO users. The only distribution anomaly that I can explain is the low number of users on channels 11 through 14... JR does not sell radios on those channels, and a lot of the fliers in our club use JR equipment. (Incidentally, you won't see channel 20 in the data above... we do not allow that channel at our field due to possible interference from a nearby TV Channel 4 broadcast.)

In any case, in order to start leveling out the usage, I keep the 4 local hobby shops supplied with the latest survey results and post a copy of the same data on the frequency board at the field. We've had some success, with fliers who've purchased new radios letting me know they used the data to avoid the crowded channels. In another 30 or 40 years, we should have this problem whipped!

Good luck... I'll be amazed if your club has ever done a survey like the one above. It IS a lot of work, believe me.
