did you try transmitting with it, and see if any skimmers pick you up? just
try sending test de urcall and check the RBN network, see how you are
getting out....

Hello,
Per many people's recommendations I added 800ft of radials today. That is 8
x 100ft each. It made a difference on the analyzer which I'll summarize
below. It was dark when I finished but here are a few data points. I think
it is better. The wide SWR curve still bothers me but the resistance is
coming up.
This is also using the new K9YC cookbook choke with 18 turns of RG400
around a 2.4" type 31 toroid.
The values are Freq, SWR, R, X, Z
1810 1.43 42.0 -14.5 44.5
1820 1.31 43.2 -10.7 44.5
1830 1.21 44.1 -6.7 44.7
1840 1.13 45.0 -2.5 45.1
1850 1.10 45.9 1.7 45.9
1860 1.14 47.0 5.7 47.3
1870 1.23 48.0 10.1 49.1
1880 1.34 49.1 14.7 51.2
Any thoughts? The 160 CW contest is only 4 days away, I don't have a lot
more time to make changes but I could run a "few" more radials...
73,
Todd - NR7RR
