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,

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 work is operating simplex - by going split and transmitting a few Hz above 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

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 -Original Message- From: Topband [mailto:topband-boun...@contesting.com] On Behalf Of Elan Paim Sent:
