[Elecraft] K4 Field Day configuration notes

[Wayne Burdick]

Field Day stresses most radios (and their operators) more than usual. That's part of the "fun" :)

Beta release 18 of the K4 software provides an "RX Dynamic Range Optimization" menu entry that should be turned ON for Field Day, even if you normally leave it off. This configures the A-to-D converter for best dynamic range. (Turning it off may slightly improve sensitivity. At present the setting applies to all bands; in a future release it may be settable per-band.)

We strongly recommend installing release 18 if your current software is older. Previous releases had only the equivalent of turning the menu entry off.

Another setting you'll find useful is MENU:RX Auto Attenuation = ON. This allows the K4 to automatically and temporarily reduce front-end gain on a per-receiver basis if extreme signal conditions exist. Such conditions are presently indicated by the "+" in the S-meter's "+60" label turning to magenta. The indication will be more prominent in the next beta release (19, due in a day or two, most likely). You can also control front-end gain manually when you see the OVF (or "+") indication.

73,
