WDOG 6930.0 kHz AM was 6960.0 kHz AM 02:36 UTC 11 SEPTEMBER 2021

02:36 UTC - WDOG heard after Ball Smacker Radio went off-air. Signal was loud and clear but rapidly faded.

KMD3HR, Chris Lobdell, CJammer and Erk86; thank you for providing the updates. I have lost the signal into my part of the world.

This is 60 feet. Is it enough to materially affect the signal?

Absolutely as you are dealing with signal amplitudes in the micro volts (uV) range which need to travel down the conductor to the feed point. The smaller the conductor the higher the resistance therefore you will get attenuation along the conductor. You also have less surface area to capture those waves.

Did you remove the insulation on the antenna wire? That as well has an attenuation factor. Then there is also the feedline loss. Every little bit makes a difference because all those little bits add up. Even the quality of the conductor can make a difference. Cheap mix alloy conductors with very little copper content make for poor antennae.

I also looked at the DXE-BFS-1 instructions and they specify:
Antenna wire: You will need a minimum of 3/8 wavelength of wire of any gauge between #8 and #20.

Your current wire is most likely 24 or 26 gage. 3/8 wavelength at 160 metres is 200+ feet of wire. Even at 1/4 wavelength you are looking at 137 feet of wire.

This is one of the USAF High Frequency Global Communications System (HFGCS) network frequencies. These messages are common and generally simulcast on all of the network's frequencies. I sometimes use this traffic to check propagation by cycling through the network. Good practise as well for receiving and copying those phonetic letter onto paper (or screen). Characters should come at you at an approximate cadence of 1 per second.

The use of small AWG telephone wire may not be the best choice in antenna wire. This wire has a typical DC resistance of approx 98 Ohms per km and a characteristic impedance of 100 Ohms from 1 to 20 MHz.

Attenuation is in the range of:
2.6 dB/100m at 1 MHz;
5.6 dB/100m at 4 MHz;
8.5 dB/100m at 8 MHz;
9.8 dB/100m at 10 MHz; and
13.1 dB/100m at 16 MHz.

Unfortunately, the result being that the signals captured by the antenna are substantially attenuated by the length of telephone wire even before they have the opportunity to hit the receiver input.
