The antenna is nothing more than a simple 2.4 metre square loop drawing pinned to the internal brick wall of the spare bedroom. Yep, thats right, the inside wall of the spare bedroom - ideal for flat dwellers, hotel rooms or whinging neighbours, The loop has a simple switched inductance at the top of the square loop and uses a simple coaxial stub to tune the antenna. An additional variable capacitor placed across the feedpoint can be used to fine tune the resonance of the antenna, by Andy G0FTD -

The Bruce array is a simple, often-forgotten wire antenna array that is advantageous for 80 and 160 meters, where typical gain antennas are very large. This bi-directional broadside vertical array is only 1\4 lambda high and does not require a ground system. It offers substantially greater SWR bandwidth than the half-square or bobtail curtain. A 4-element Bruce array used by N6LF showed a gain of about 4.6 dB compared to a 1\4 lambda vertical with 8 elevated radials, with a 2:1 SWR bandwidth greater than 400 kHz. The antenna is simple and its dimensions are flexible. -

The 20 thru 10 meter dipole is constructed from stranded insulated wire available in most hardware stores. The feedpoint uses an 8 inch long section of 2 inch diameter PVC pipe. A section of wire joins the elements at either side of the feedpoint to avoid the inductance of square knots used on lower frequencies. -
CCUser DX Spot Client is a robust Windows-based Telnet and TNC program for DX cluster systems like CC Cluster, DX Spider, and others. It offers features like multiple Telnet connections, advanced DX spot filtering, bearing/distance display, and integration with LoTW and eQSL. Users benefit from band-specific color coding, missed spot recovery, and detailed DX data, including zones and grid squares. Additional functionalities include chat groups, DX alarms, and WWV data display. It supports logging and contest tools via Telnet, DDE, and RS-232 outputs. -
