Propagation. Long distance low and medium frequency (below 2 MHz) propagation along paths north of due west over upper middle latitudes is poor. Propagation on long distance northeast-southwest paths is poor. Forecast. The geomagnetic field is expected to be quiet on July 9 with a chance of unsettled intervals due to possible effects from CH626. 220 MHz: 3500 V/W: AC (300 kHz) download: BPD270MA5: InGaAs : 270 MHz: 3500 V/W: AC (5 MHz) download: BPD450MA: InGaAs : 450 MHz: 3500 V/W: AC (300 kHz) download: BPD600MA: ... e.g. for pulse monitoring, propagation time measurements, offset locks, etc. Due to their high trans-impedance gain and low noise, these diodes are also well-suited for.
SPLAT! is an RF Signal Propagation, Loss, And Terrain analysis tool for the electromagnetic spectrum between 20 MHz and 20 GHz. It is free and open source, and there are builds for Windows and Mac if you don't want to compile from source on linux yourself. I haven't used it, so I can't speak to ease of use, but it should generate propagation maps based on.

220 Mhz SSB has propagation characteristics of both 2 meter and 440 from what I have been told. During a good tropo ducting opening, the 220 band would really shine. It would be a shame if this band (or any other ham band) would go away because it was being under utilized because manufacturers don't want to include it. Ground plane ferrite treatment, inductive loading, resistive termination and impedance matching techniques are adopted to raise the gain between 200-300 MHz and achieve the stated goals. As the aperture size is about λ/3.5 at 220 MHz and only λ/30 in height, achieving 0 dBi (from 220-500 MHZ) is quite challenging.

Sporadic E A type of sky-wave propagation that allows long distance. communication on the VHF bands (6 meters, 2 meters and 220 Mhz) through the E region of the atmosphere. Occurs only sporadically during certain times of the year. Most common.

I enjoy comparing propagation on the VHF/UHF ham bands but don't have a good way to fairly test base to mobile simplex on 220 MHz. I have both the Alinco DR-235 and an AnyTone AT-588 (basically same radio as the TYT-9000D) which are nice radios, but it's still really unfortunate none of the "big 3" make a monobander mobile for 1.25m.
