For many decades radio amateurs have built antennas with wood and wire and have had great success using their home brew creations. This antenna was built in the same tradition and I am pleased to say that I made my first satellite contact using such an antenna. To make this antenna I only...
In contrast, FM and AM radio became the most reliable sources of information. Here in Buncombe County, public information and news were broadcast on 99.9 MHz (FM) and 570 kHz (AM). Both stations stayed online throughout the disaster, and the information they provided reached a vast audience....
Some inexpensive set top boxes found on the internet will receive DVB-T but may not tune the ham band without a downconverter or not do the narrower 2 MHz bandwidth mode in the 70cm band. However, prices are coming down, see Hi-Des HV-100EH modulator and HV-110 receiver made for the...
This is a good method to look at your antennas bandwidth. The graph shows to sample readings that you could expect from a 4 element beam, and a 5/8 Wave antenna. The 1/2 Wavelength Dipole Antenna When the first radio experimenters were first trying out their systems, they would just ...
//www.worldradiohistory.com/Archive-DX/Ham%20Radio/80s/Ham-Radio-198411.pdf). It’s become difficult to find the classic 2N5109 transistor, so I am using the more modern BFU90Q, which has similar performance. But I am simulating with the 2N5109 because that’s the model I could find....
to 450 MHz. However, there may be a method to enable (or unlock) the entire frequency range for transmitting. Check the specifications of your radio model. These radios are almost always FM only, so no AM or SSB. Some radios can receive AM in the aircraft band but won’t transmit AM...
I had convinced myself that the KX3 should stay in the Shack. So being the wise and kind husband that I am; I started looking for a small, portable, inexpensive QRO capable radio, given the compromised antenna. All this was to please my wife of course. ...
Is 4 kHz of bandwidth needed ? Then my answer would be a question; Is 2.4 kHz sufficient to produce the human voice accurately? My answer to that would be an emphatic NO! And just because is has been “good enough”, doesn’t mean that we shouldn’t pursue some improvements. Isn’t...
