HF radio in more severe weather conditions. Given that many users of HF radio – for military communications or humanitarian needs, for example – operate in extreme environments, there may be more than just rain to contend with. Stormy conditions, as can be expected at certain times of year in tropical zones, can lead to increased background noise on radio networks due to static caused by lightning. This atmospheric noise caused by thunderstorms is a major contributing to radio noise in ...

Cold weather can sap the life out of your battery operated radio equipment. The newer generation lithium-ion and Nickel Metal-Oxide batteries have better cold weather tolerance than the older Ni-Cad cells. But as the temperature dips below zero, you can expect a reduces battery life. I always keep a spare battery warm in an interior pocket of my jacket. Clip your radio to an inner layer of your clothing and run a speaker mic and earpiece to your face. A speaker mic with a large button is ...

As a new ham, it was invaluable. I learned how to operate complicated radios, with several visits to RTFM. We identified shortfalls in our plan and the limits of the equipment, and are both updating our plans and identifying resolutions for the equipment problems we had experienced. 160m End-fed antenna strung out over 240 feet. We met Saturday morning at 0800, unloaded our vehicles of sleeping bags, food, and cold weather clothes. Some brought tools and spare parts. At about 9, we started ...

When the leaves fall off, signal levels are better. Finally, ground conductivity is better when the ground is cold. To the extent that your signals are attenuated by ground effects, the attenuation will be less in cold weather. This “summer/winter affect” can noticed easily on the Medium Wave band where AM stations operate.

I have done some pretty extensive work with HAM radio and satellite comms. There are several challenges that you would need to overcome to work the FM easy SATs. The first would be knowing which satellite is going to be over head at exactly what time of day and exactly where it will come up over the horizon. The pass of each satellite only lasts around 8-12 minutes as they are not in a geosynchronous orbit.

If an astronaut carries a handheld ham radio with a power output of 4/5 watts; he can communicate with an operator easily. So, standing from the window of his carrier in the space; the astronaut can see the antenna of the other ham as long as they are in the same line of sight. That makes it possible to easily communicate with the ground operator. With this simple technology that all the ham radios including the dual band mobile radio possess; the astronaut can easily chat with the man in ...

The semiconductors which comprise the bulk of components in all modern ham gear are rated to operate over at least the "commercial" temperature range whose low end is 0C / 32F. Since most active and passive components have a positive temperature coefficient of resistance, one would expect inrush current to be the dominant failure mode.

One that featured readily on prepper blogs and forums is ham (or amateur) radio. Being new to prepping ham radio is something I wanted to make a priority to learn about as it presents as an essential alternative to conventional ways of communicating. This lead me to ask the question: what are the advantages of ham radio during a disaster? Ham radio does not rely on pre-established communication grids and massive info-structure to communicate ; You only need 3 things to make a ham radio work ...
