*Good Morning Brandon,I don't know of a web page that comes close to identifying what's happening with ten meter propagation.... The little knowledge that I have comes from many years of observing the 10 meter propagation phenomena.
I do know some things about backscatter signals..... when the ions over the equator area is sufficiently charged enough to reflect some of a signal close to 180°. The trans equatorial path being open is a good indication that backscatter can occur.
Operators with directional antennas in the Northern hemisphere can point their antennas South East early, South at mid day & South West later in the day and can expect backscatter signals if the TEP is open. Backscatter signals quite often will have a "flutter" or "watery" sound and are subject to very rapid fading in and out. I have logged backscatter signals with an East/West dipole but, generally any antenna other than a direction agile antenna is useless.
Usually "E" reflections can be expected in the day time and early evening during the month of December (Northern Hemisphere) and June & July..... However, weather conditions often seem to cause E clouds to form at very odd times....including thunderstorms and frontal systems.

Hi Bill. I am fascinated by 10 meter propagation but am still very low on the learning curve. Can you or anyone else on the list recommend a good web site or book that helps one identify what propagation mode they may be receiving? Another one mentioned a bit is back scatter.I've done a bit of 'googling' on 10 meter propagation, but not found anything yet that really helps a novice determine the propagation mode of a signal they are receiving.My report of possible E skip last night regarding reception of AC0MO, I am now pretty sure it was meteor scatter. Rapid fade up to an excellent signal and then slightly less rapid fade out less than a minute later.I have noticed some evenings that the band dies out at sunset, but other evenings some signals are present into 0100 UT, tonight for instance. AC4DJ (FL) and K5AB (TX) are audible here in W TN at 0130 UT after the band is generally dead. Are these E skip?73, BrandonOn Dec 5, 2013, at 7:13 PM, WJ5O <wj5o@xxxxxxxxxxxxx <mailto:wj5o@xxxxxxxxxxxxx>> wrote:*Joshua,They are terms used to describe which cloud layer reflects the signal....The E layer is ion charged clouds much lower in the atmosphere and will cause a reflected signal to be near the listener..... F layer reflections will cause the listener to be a greater distance from the beacon station. Sometimes multi hop Es will be considered F layer reflections. Note my mileage entries below and quite likely all those over 1500 miles from my location are F layer reflections.Questions?...Don't hesitate to ask. 73 Bill WJ5O*On 12/5/2013 5:21 PM, Joshua Inman wrote:What are the e's and the f's?
