Re: Preliminary results -- W8TEE/AC8GY Mag Loop Testing
Hello Jack,
Thanks. I found references to those and intend to follow up. That is part of the "way forward" I mentioned. Once upon a time, before there was an IBM PC or Apple at my house I started to wade into programming. The programs I could buy did what somebody else wanted to do and do it the way they wanted to do it. I started building my own databases. Before very long I found "user configurable" software and dropped the programming effort. What I learned in those days barely applies today.
'They' like to say "they don't build things like they used to". Generally that is a lament. I say thank GOD! <evil grin>

If that fills the bill, great. If there are some "programming gaps" you feel need more detail, take a look at the reviews on Amazon for Beginning C for Arduino to see if you think it might help. If you already know a programming language, you probably don't need it.

Re: Preliminary results -- W8TEE/AC8GY Mag Loop Testing
Now Ozarkon is on my bucket list..... may try to make it part of a visit to Oklahoma City and visit to relatives. See you next year. The two new hams I took with me this year are infected and getting ready to take other friends to FDIM and Dayton next year. Those that don¡¯t want FDIM can do Contest University.

Yes, that was a compliment. Also enjoyed your humorous and instructive talk at FDIM. Keep up the informative instruction and assistance on these sites. Ham radio (and other hobbies) are pure joy now with the internet and yahoo/io groups. Just think if we had these helps back when we started how many would have stayed in radio after the first discouraging fail or two.
Thanks again.

Re: AZ ScQRPions Meeting, Prescott Hamfest this Saturday.
Bob et al,
I will be going to Prescott early Sat a.m.? Then I'll be going over to the
school just off of Fain Rd and N Robert Rd to see an old group that I
used to fly R/C gliders with and will be starting back up when I get back
from Dallas the weekend of Ham-Com in Plano.
If it is lunch time, I may just visit the Fuddrucker's near the movie theatre
in Prescott Valley.
See you tomorrow,
chuck, k7qo

AZ ScQRPions Meeting, Prescott Hamfest this Saturday.
Well I finally got my email working again so I'm late getting this out to
all of you.
THIS SATURDAY IS BOTH THE PRESCOTT HAMFEST AND THE REGULAR AZ SCQRPIONS
MEETING AT FUDDRUCKERS, I17 AND DUNLAP. 10:45 AS USUAL.
IF YOU ARE A KAMAKAZEE AND GET UP AT OH DARK THIRTY TO MAKE IT TO PRESCOTT
AND THEN BACK TO PHOENIX BY 11AM, I HOPE YOU FIND SOMETHING SPECIAL FOR
SHOW AND TELL AT LUNCH! i AM NOT A KAMAKAZEE SO I WILL BE GOING TO THE
MEETING ONLY.
AS USUAL, IF YOU HAVE SOMETHING FOR SHOW AND TELL, OR JUST DID SOMETHING
SPECIAL FOR YOU, COME TO THE MEETING AND SHARE IT WILL THE GANG.
YES, I KNOW, IM SHOUTING! I DIDN'T WANT ANYONE TO NOT SEE THE MESSAGE! ;>)

Re: Preliminary results -- W8TEE/AC8GY Mag Loop Testing
We agree. The question we're trying to answer is: How much are we giving up with a ML verses an EFHW (or other) antenna? If we get the time, we might also test against a vertical, too. Any ML is a compromise--I think we all know that. However, do the physical design variations possible for a ML significantly alter its relative performance? Since I used to teach graduate-level stats courses, I'm always bothered by non-quantitative statements like "it performs better" than such-and-such. I much prefer something like "The mag loop gives up 2db (+/- 1.96¦Ò) over a reference dipole." That statement conveys much more information about the test being made. We made a post yesterday about the relative efficiency of the ML and there's a significant hit on 40M, but less on 20M. Part of the question is: Can I afford to take that hit?
To us, the question sometimes boils down to: Which is better for my hobby when constrained with an HOA agreement: 1) a mag loop, or 2) finding a new hobby.
