Hi Trevor,
I looked at your QRZ.COM page and I'm concerned that your tower
and Yagis may be degrading the performance of your nearby 160
meter vertical. It can contribute unwanted nulls and unwanted
ground loss. What is the height of your tower to the top of your mast?
Small loop antennas
I understand that I have to improve my RX antennas as currently I find the TX
antenna is better on RX that both of my current RX antennas, While I get a good
reduction in noise floor on the RX antenna's the DX just isn't workable on them
The TX antenna is 55ft of Aluminum Tube It tapers from
Hi Marsh
I agree. This is a basic technique and I’ve used it for decades.While
stations butt heads on the “zero beat” frequency I transmit 100 to 200 Hz
above and usually make the contact. During the ARRL 160 Meter contest
there were times I was transmitting 300 to 400 Hz high to make the
Jose,
First thank you for the QSO. You are one of the few Europeans I have worked on
160 with my very modest station in southern Arizona and are a new one for me.
I think the that the key here is "a few Hz" offset. Of course 100 Hz is more
than a few and would be too much for a receiving
That's not going to work often during a contest. It depends on how crowded
is the band you stretch or narrow your passband. When a narrow filter is
set if you call 100 Hz away we won't hear you.
During a dxp the scenario is quite different, you're the alone, I normally
set, whenever is possible,
Shh. You're giving away my secrets.

I respectfully disagree with Don Kirk. My experience has been different. I
don't how many pileups I've broken quickly - where the station I'm trying to

or below "zero beat". The operator at the other end is trying to copy a
Hi Trevor,
Besides your TX antenna, another issue I have observed over the years is
the importance of being as close to zero beat as possible. The modern HF
radios offer very narrow RX filtering options, and during very crowded band
conditions most of the stations are running very tight filters
Hi Trevor,
Please share with us the details of your antenna and ground system
Better transmit performance should be achievable

Hello Rune, from Ed KG4W. I found conditions last night the same as you did.
The only Eu station I copied was OZ1OP, but he no copy me.
But last weekend, conditions were real good. I was not on past 0300z but
worked these DX

Before worrying about the type of antenna, you should evaluate the needed
ground system. As without an effective ground system the actual antenna is
of little consequence. 73 Clive GM3POI

I see from your QRZ page that you already have several towers and Yagi.
Have you considered using one as a top-loaded vertical? Do a Google search.

Hi
Is any one have any experience with
Vertical fir160/80 m ?
I think zero five have some.
But not sure however if I can built my salfe it will be great
Thank you kind
Happy holiday to all
