Maybe this will help:
When talking about Fishing, the US Government defines an Active Fishing Hobbyist as someone that goes fishing 52 or more times a year! 73 es Gud DX! Young "Michael Coslo" wrote in message ... Another thread got me thinking about the number of active Hams. Just what percentage of Amateurs are active ones, defining active as either being on the air regularly, or participating in Amateur related activities on a regular basis? (like say on a weekly basis?) Thoughts? - 73 de Mike KB3EIA - |

With most surveys, there's no correlation between the response rate and what you're trying to measure. If you're asking for someone's opinion on an issue, you do a survey and get 10% response, you can assume that the results are valid even though 90% of the people who received the survey didn't bother to respond. In a survey that asks licensed hams if they're active, if you get 10% response, do you assume that the other 90% are inactive hams? No, you can't do that. But you have to assume that an active ham is more likely to respond to a survey about ham radio than an inactive one. Thus the response is likely to be significantly skewed towards activity. If there are any statisticians among the readers, please tell us how many hams we'd have to sample to get a valid measurement. For opinion surveys, the more you survey, the higher the accuracy. In this case, I'm not sure that adding more people to the survey improves the accuracy since active hams are more likely to respond. The key is how to interpret the non-responders, something that seems unknowable. I don't claim to be a statistician, so I would appreciate comments from someone who is. 73, Steve KB9X Steve, Those are good points. I'd guess that a "valid" survey would have provisions to account for all those surveyed, including a method to weed out silent keys, and provision for guarding against "false positives", i.e., knee-jerk "Yes, I'm active" responses. What little I remember from college statistics tells me that the design of the questions is all-important. The survey mustn't cue the respondent as to "right" or "wrong" answers, and must provide "discriminator" questions to confirm and/or deny the accuracy of previous answers. It's a job for an expert: if we called someone up and asked "Are you active?", the results would be skewed, as you point out. However, if the question is, e.g. "Will you help with disaster preparedness as a ham?", you risk getting a "novelty" response, i.e., a respondent who says "Yes" just because he/she hasn't done it before. Questions about purchasing are less likely to show bias, but there's always the problem of "what do the answers mean?": if a ham says he's going to buy a new rig this year, is he just trying to please the questioner, is he window shopping, or is he just wishing out loud? This is all theoretical, of course. The first issue is to define what "active" means, and then we'd need a survey that accurately measures the ham population for that metric. Short of putting remote RF sensors at a statistically-valid percentage of ham operator's homes, I'm out of ideas. HTH.

Short of putting remote RF sensors at a statistically-valid percentage of ham operator's homes, I'm out of ideas. For an accurate survey, instead of defining active, we would need to have several questions related to activity. We'd want to first ask the respondent if they considered themselves active, then questions would follow asking about how many times per month they are involved in any of several Amateur related activities. Just a definition is almost impossible to arrive at. Even if a group came to a consensus, the next person might not accept that at all. Just here we see where I was looking at activity relating to things on a weekly basis, another poster on more of a monthly/yearly basis, and yet another looked at active as one who takes the trouble to renew their license. All of those opinions are valid, even though that spans an extreme range from someone like me who spends several hours each day involved in one activity or another related to the ARS, to someone who never gets on the air, but renews their license. In the end, the survey folks tend to express results in terms of percentages, such as "20 percent of those who responded use their radios on a daily basis." 30 percent of respondents participate at least once a year in a public service event. The nasty little line in all that is "those who responded". And just like college football rankings, no matter how sophisticated the computer program, somewhere, someone is going to make the first decisions which will be based pretty much on opinion. GIGO, so to speak. It truly isn't simple, eh? - 73 de Mike KB3EIA - |

The idea of the exercise was to determine what percentage of the folks listed by the FCC as licensed amateur radio operators that has actually contributed to the hobby in the recent past, or might do so in the near future. "....contributed to the hobby"? I hear a lot of "active" hams (regularly on the air) whose "contribution" is "59 Old Man, QTH here is Resume Speed, Arizona, and the name is Broken Old Bottle. Sebentee Tree. XYL is calling me for lunch". Good for them. They're enoying themselves. I don't think "being active" has any direct correlation to "contributed to the hobby in the recent past". Most of us are involved in the hobby for our personal enjoyment, no more, no less. Some small percentage may consider that they are "contributing"..... good for them, but such noble purpose isn't a requirement to be considered "active".

I don't think "being active" has any direct correlation to "contributed to the hobby in the recent past". An iteresting idea. I was equating "active" with "contributed to the hobby". This is, perhaps, naive. Back when I was a kid, I listened to hams on the air, and was motivated to get my license. I wonder if people today, listening to much of what I hear on the ham bands, would be motivated to get involved in the hobby. Are these guys "contributing to the hobby"? I do wonder. Most of us are involved in the hobby for our personal enjoyment, no more, no less. Some small percentage may consider that they are "contributing"..... good for them, but such noble purpose isn't a requirement to be considered "active". You are, reasonably, interpreting my words in a different way than I meant them. I was equating "generating RF on the ARS frequencies" with "contributing to the hobby". I was actually trying to be more liberal and include the folks whose interests involved designing or building equipment (whether they used it or not on the air) or other positive contributions like teaching classes, being active in their local club, and so on. Now that you mention it, I realize that "contributed to the hobby" and "active" can be quite different. The malicious jammer, or the frequency policeman on 75 meters, are "active". They may not be contributing to the hobby. Food for thought. 73, Steve KB9X |

The derisive comment above sounds like that of my very sarcastic brother who, in spite of holding an extra class license for many years, hasn't been on the air for the same very many years because he doesn't want to talk to hams who sound like that, thereby assuming that all hams do. Like "active", "contributed to the hobby" requires a definition (which I didn't provide). Hams who sound like the above "contribute to the hobby" by: (a) occupying spectrum space which otherwise would show up as "unoccupied" , i.e. available for grabbing by some "untouched-by- human-brain" electronic occupancy detector, and (b) providing an example of what not to sound like on the air so that newcomers will know what to avoid doing. -- 73 de K2ASP - Phil Kane From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon e-mail: k2asp [at] arrl [dot] net |

It wasn't intended to be derisive, just an example to support my premise that even the most mundane QSO is, after all, "activity", and meets KB9X's definition of "contributing".
