NOAA weather stations usually have ham radio operators and equipment on board at you local weather station to monitor the "spotter ham radio frequencies" so they can get the severe weather reports out to the public much faster. Many "eyes" on the ground are much better than radar in many c...
These are Fire Mutual Aid channels (VFIRE21, VFIRE22, VFIRE23) set aside for when multiple fire districts need to communicate. Typically, each district has their own radio frequencies and only uses these when a large incident occurs with multiple agencies responding. An FCC license for these ...
To be clear, contacts with XSG will be cross-band contacts where XSG will operate on its authorized frequencies outside of the amateur radio bands, and any amateur radio operator making contact will operate within their own allocated amateur frequencies as listed above. Operators should exercise ca...
The imagery presented on our main web page, is NOAA APT imagery, which is transmitted by NOAA satellites at radio frequencies of 137.50, 137.62 or 137.9125 MHz, FM. You may have noticed that your broadcast FM radio tops-out at 108MHz. If you could keep spinning your radio dial beyond 108...
No! Our antennas actually perform well over a range of frequencies. Most commercial CB antennas are designed to operate well over the 40 channels (that is a frequency range from 26.965 – 27.405 MHz). So, if you use your radio on all those frequencies it would be best to make it ...
I don't have any free frequencies for today's 20m net at my home QTH. The 20m band in the General portion (where we run these nets) is rammed solid here. If I can't find a 3Khz window by about 11:15am (CST), unless someone else can work it from a different location that's...
As far as standard memories, its operation is a bit disappointing. My Eagle and KX3 store both VFOA and VFOB frequencies when I save a memory, but the DX10 is only saving the VFOA frequency. On the other radios I like to quickly jump up to SSB by simply pressing the VFO A/B swap...
LPDAs are commonly used in amateur radio for HF and VHF/UHF communications, particularly by operators who need a multi-band antenna that can cover a wide range of frequencies without requiring multiple antennas. They are also used in broadcasting, where wideband performance is essential, and in ...
Because the various solar conditions affect HF frequencies in different ways, calculations are provided for four HF band spectrums separately. Calculations take into account the indices, background radiation, day/night conditions, and also take into account both propagation and noise. While the band ...
