Field Day Results - I'm somewhat confused by the category

[KK6RF]

I'm looking at the Field Day 2011 Results Database and I'm having a hard time understanding the category. I think it goes Number of Transmitters, Class, Participants, Not Sure (Battery?). So, lets look at some categories that start with 1B:

Category Pwr Mlt Entries
1B       2         1
1B1      2        35
1B1B     2/5     159
1B1C     1/2      17

Let's take them one at a time...

1B - 1 TX, 5W and no participants ??? It must be a typo since there is only one entry. Right ???

1B1 - 1 TX, 5W, and 1 participant. OK... This makes sense. Running 5W from commercial mains or a generator.

1B1B - 1 TX, 5W, 1 participant, battery ???. Why are there some entries with a 2 multiplier? Did they run off batteries but charge them from the mains during Field Day ???

1B1C - 1 TX, 5W, 1 participant, mobile ??? Wouldn't a mobile station start with 1C ??? Assuming the C stands for mobile, would you say 1B KK6RF or 1C KK6RF during Field Day ???

Go easy on me tonight. I have a headache. This collection agency called me today and we got into it over the phone. The stupid lady was a real... Ummm... Let's just say she was Class C.

It seems all the 1B stations are further broken down by operator and an additional letter suggesting if battery and under 5 watts.

If you look at the QST magazine posted results...

http://www.arrl.org/files/file/Conte...011-FD-QST.pdf

You will see the following 1B categories...

1B1 = 1TX, B Class, One operator
1B1B = 1TX, B Class, One operator, Battery (5 Watts or less and on Battery)
1B1 again for some reason with a completely different list of entrants.
1B2 = 1TX, B Class, Two Operators
1B2B = 1TX, B Class, Two Operators, Battery (5 Watts or less and on Battery)
1B2 again for some reason with a completely different list of entrants.

I have no idea where the C in 1B1C comes from. The only thing I can figure is Mobile, but those are simply class 1C.

Clear as mud?

Clear as mud?

Yea... Clear as mud! I guess since it's "not a contest", accurate reporting of the scores is not necessary. And judging by the lack of responses to this thread, other hams don't seem too concerned either. Which just goes to show that Field Day is all about having fun...

1B - 1 TX, 5W and no participants ??? It must be a typo since there is only one entry. Right ???

There's no number after the B so they didn't indicate the number of participants. 1B can be 1 or 2 ops, and they are tabulated separately.

The power multiplier of 2 means that they were running 150 watts or less, and on emergency power.

B category does NOT automatically mean QRP.

1B1 - 1 TX, 5W, and 1 participant. OK... This makes sense. Running 5W from commercial mains or a generator.

NO!

B does NOT automatically mean QRP.

The power multiplier of 2 means they were running 150 watts or less, and on emergency power.

1B1B - 1 TX, 5W, 1 participant, battery ???. Why are there some entries with a 2 multiplier? Did they run off batteries but charge them from the mains during Field Day ???

Some probably did just that. Remember that in order to get the 5 multiplier, you must be QRP and not use commercial mains or generator.

1B1C - 1 TX, 5W, 1 participant, mobile ??? Wouldn't a mobile station start with 1C ??? Assuming the C stands for mobile, would you say 1B KK6RF or 1C KK6RF during Field Day ???

No. The C isn't for mobile; it's for commercial power. 1B1C would be a 1 transmitter, 1 operator station in the field running on commercial power.

1B

there's no number after the b so they didn't indicate the number of participants. 1b can be 1 or 2 ops, and they are tabulated separately.

The power multiplier of 2 means that they were running 150 watts or less, and on emergency power.

B category does not automatically mean qrp.

I don't think so... The database lists W5HLP as the only 1B station. However, if you check the published results in the December QST, W5HLP is listed as 1B1B and there are no 1B entries. My guess is it's just an error in the database.

1B1

no!

b does not automatically mean qrp.

The power multiplier of 2 means they were running 150 watts or less, and on emergency power.

OK... Class B does not mean 5 Watts. My mistake...

1B1B

Some probably did just that. Remember that in order to get the 5 multiplier, you must be qrp and not use commercial mains or generator.

Agreed.

1B1C

No. The c isn't for mobile; it's for commercial power. 1b1c would be a 1 transmitter, 1 operator station in the field running on commercial power.

I think you're right. Also, John, KX4O, pointed out that 1B1 was listed twice in the QST published results. I believe the second 1B1 group in the published QST results starting with WC7Q is the 1B1C group. If you check the database, WC7Q is at the top of the 1B1C entries. It looks like they forgot to put Commercial Power next to second 1B-1 Op entries the in the QST published results. Sloppy and confusing...

Well, I think I've got it now. Thanks for the help!
