Re: Wire length question
I have always measured to where the wire goes through the insulator. In the real world unless you have some very accurate test equipment you will never know the difference in resonant frequency

Re: Wire length question
I think yes is sort of correct. Some of the knot is not an effective radiator.
The real question is does it matter. I don't think so.

Wire length question
I realize this might be a silly question and the significance to the overall wire length minimal but the question is burning a hole in my head: Do you count the part of the wire that is tied around

Re: Real life Em Comm
I killed a number of police districts and was surp2 to discover they do not monitor the VHF/UHF bands.
Thank God for vigelant Jams.

Clallam County 911 was been advised of the situation. Ham is slowly progressing down the mountain and things are looking good.

Real life Em Comm
Just got my DMR digital/analog radio on the air. Set it to scan the analog stations, lol. Immediately picked up a backpacking injured ham giving his information to another ham who had been on the QSO

Thanks Paul and Kirt-
What Are the coordinates of the cougar mountain repeater? I was thinking it was nearly due south of Duvall but I’m not sure

Re: Best software to find bearing
I grit my teeth and use Google Earth Pro.
I make it a bearing of 204 degrees and a distance of about 14.8 miles. That’s to a point just a bit east of Duvall, I’m not real clear on exactly where

Re: Best software to find bearing
The web version doesn’t have it but if you download the Google earth app it includes a ruler tool that will give you a bearing. I thought I once did this with Gaia GPS but I couldn’t find it there

Best software to find bearing
I'm setting up a small 440mhz 7 element yagi and would like to find the compass bearings to several "targets". I don't see a bearing on google maps. What do folks recommend?
Thanks and have a happy
