Because I cache data and banners in order to reduce the bandwidth and processing, not only on my server, but also the servers I get my data. Data that I get for the banners is cached every 15 minutes. The banner image you download is also cached every 10 minutes. This rarely impacts ...
and it roughly fits into a 2500 Hz bandwidth, which is often the IF bandwidth of the receiver being used. Some authors make this explicit by tagging this SNR as SNR2500. It is common practice
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 ...
Although many common scanning radio receivers can tune to 137MHz FM, the receiver’s bandwidth may be too narrow to receive the full signal, as indicated by poorer sound quality and absence of high-pitched tones. Narrow receiver bandwidth becomes apparent when the APT ‘tick-tock’ sound is c...

If you search the Web for the origin of the term "HAM" for radio amateurs, you will find two or three accounts that are evidently most believed. However, this version seems to be the most credible. It was provided to me by a very active and accomplished HAM, Mr. Cornell D., who is...
