Lyle & Dave,
Thank you so much for your explanations.
I realize all the efforts I have put in towards my 150 meter radial
field had to work in my favor. I am on the ocean and my back yard is
a salt water marsh. I use the first tall tree at the marsh's edge as
the support for my 160 meter inverted-L. It is electrically long and
I use doorknobs at the feed point to give me a 1:1 match at 1.830.
I have 60 some 130' radials laid out with 1/2 of them on the marsh
and the rest on the bog beside it. I have the same kind of L attached
to the radial plate for 80M and in the center of the plate is
attached a butternut HF9V. The get selected via an Ameritron remote
coax switch. FWIW, I do extremely well on low bands with this for I'm
forever hearing in contests how powerful my signal is yet I always
adhere to less than 1500W out. CW I set at around 1,100 watts out in
a contest just so I know my score is guaranteed to be legit.
Several days ago I worked at the K3 stated 100mw level and was amazed
by how many replies I was able to get on 160M & 80M. I had started
out at 5W and gotten several replies and then when I received a 579
from Wisconsin on 160, I dropped to the lowest the scale offered at
100mw and he gave me a 459. I called more CQs at 100mw and worked a
NC, IA and MI back to back, to back. I wanted to go lower and try
10mw, even 1mw if possible but was not sure how to do this without
possibly transmitting into the wrong output.
I am on the road at the moment but will try your suggestions when I
get back.
Amazing what an advantageous antenna system will do. I entered the
SSB contest for two hours last night just to give people some
contacts/multipliers. The C6 I worked said he'd heard me earlier and
took the time to tell me several sentences worth how powerful my
signal was. The same for several VE stations and one from WV. I know
the antenna is big in those reports but I also wonder how much using
the K3 with it's compression played a part as well?
