The molecular ions (e.g., O2+ in the E region) have been further acted on by solar radiation, with the 910- 980 Ångstrom (Lyman continuum) and 350-200 Ångstrom ranges being the most responsible. Temperatures of 1400-1500° K are found, but this isn't much in terms of calories with so few particles involved. Unlike Es, the F2 layer shows a wide variety of heights (250-400 km) that depend on time of day, season, solar level, and geomagnetic latit- ude. Thus angles of incidence (and M factors from the Secant Law) are not as simply arrived. In addition, signal reflection (more properly "refraction") takes place over depths of tens of kilometers compared to the 1 km or so depth found in Es. All else being equal, DX signals via F-layer propagation will normal- ly be stronger than Es ones since the neutral particle density is much lower (i.e., fewer electron collisions and thus less absorption). This is easily attested to by those who have heard a 35-MHz pager by each mode. (e.g., from here KMD 342, Fresno, CA). Solar activity control of the F2 layer over a sunspot cycle is such that the typical maximum electron densities may vary from a low of some 500,000 per cc to a value 2 or 3 times that (or, as the case with the very large Cycle 19, a factor of 6 or 7 times it). These higher densit- ies occur at progressively higher altitudes. The limit for F2 MUF's (not counting transequatorial scatter, to be covered later) have ranged up in the 70 MHz region. The Japan-Okinawa region is well noted for such high levels due to a proper combination of geomagnetic and geographic location. -to be continued- 73, Pat Signature, 1,689 bytes WA5IYX
