SFI index: Solar Flux Index: Is a gauge of the level of solar particles and magnetic fields reaching our atmosphere and their impact . In other words, this value tells The solar flux index was in the 60s for months at a time, and all you could read in the DX bulletins was how awful things were. However - HF bands seem to 6 days ago QRZ NOW – Ham Radio News Predicted planetary A index is 5 on March 13- 26, then 12 and 8 on March 27-28, 5 on For more information concerning radio propagation, see http://www.arrl.org/propagation and the ARRL These graphs show the solar x-ray flux levels for the past three days, as well as the x-rays can ionize the D-layer of the ionosphere, causing HF radio blackouts . Usually higher K index values suggest propagation will be poor, however 6 Apr 2018 Contains solar and radio propagation information applicable to ham radio including solar conditions, space conditions, SFI, SN, A-Index,

Solar flux is measured in solar flux units (SFUs). It is the amount of radio noise or flux emitted at a frequency of 2800 MHz (10.7 cm, hence is it also called the 10.7 cm flux index). NOAA broadcasts geophysical alert messages over WWV at 18 minutes after the hour and from WWVH at 45 minutes after the hour. The messages are less than 45

I installed solar last year and I regret it as respects ham radio. I have very large amounts of RFI from my own system, during the day and possibly some at night as well. I wasn't very active in ham radio when I installed it and now I am again. The noise is on every band from 80m to 2m. Perhaps there's a newer thread I should post on.
Solar Powered Ham Radio. For setting up your solar-powered station, there are 3 items you will need: 1 – Battery. The battery is where you get your power from. The recommended battery for the setup is a 12V Sealed Lead Acid (SLA for short) – Pb. This is practically the same as the more common car batteries and they come in various To address the need, I’ve come up with a simple solution that really works and is priced right. I call it The Off Grid Ham 100 Watts for $300 Solar Energy Plant. If you need inexpensive solar power for amateur radio and/or prepping and don’t know where to start, then you’ve landed on the right web page. Setting up Chicago Electric solar panel kits is easy. The solar panel kit comes with three 15 watt solar panels – simply connect the solar panels to your own 12 volt DC storage battery, and then use at least a 300 watt power inverter (sold separately) to power your 120 volt AC appliances anywhere. Solar activity can aid or hamper HF propagation beyond line-of-sight range. Many information sources can help us keep up with solar conditions. This month, ARRL Laboratory Technician Mike Gruber, WA1SVF, assisted by Senior Technical Editor Dean Straw, N6BV, answers some questions about how Ol' Sol influences the propagation of radio signals. I installed solar last year and I regret it as respects ham radio. I have very large amounts of RFI from my own system, during the day and possibly some at night as well. I wasn't very active in ham radio when I installed it and now I am again. The noise is on every band from 80m to 2m. Perhaps there's a newer thread I should post on. Solar power is ideal for radio communications as the DC power does not introduce line noise or 60 cycle hum. Isolation from the grid (in most installations) also will assure relative immunity from grid power surges. Using solar energy as a power source actually fulfills a prime mission of amateur radio: reliable emergency communications. Solar
