Welcome to Malloy Communications, your number one resource for custom build MF/HF/VHF base station platforms. Included are GMDSS and military air to ground radio systems.
Please note: I have retired Malloy Communications with the exception of working on my HF tactical antenna and some possible future HF radio projects. At present I am devoting my time to technical investigation and RF principles associated with amateur radio.
Please browse through our site to learn more about what we do, or contact us for more information.
Listed below is a link to the NOAA Solar Flux Index. The Kp observations (vertical graph) allows the observer to take a reading of the D,E,F1,&F2 layers of the Ionosphere. The Kp index is updated every 3 hours. If you operate HF, you must keep track of solar emissions and atmospheric conditions.
