These may be used, for example, for factory and in-service testing of standby generators. A load bank may be used to stabilize a power system in case of loss of load, for example, on an isolated wind or mini-hydro plant. An electronic load (or e-load) is a device or assembly that simulates loading on an electronic circuit. It is used as ...
The software code is now open source and is developed by a small team. The program is designed for sending and receiving low-power transmissions to test propagation paths on the MF and HF bands. WSPR implements a protocol designed for probing potential propagation paths with low-power transmissions.
The set operates in the 2–29.9999 MHz range with a possible 280,000 channels. [2] RF power output is a selectable 3 or 30 watts. [ 2 ] Derived from an earlier prototype known as the B20, [ 3 ] the PRC 320 can be used as a manpack (backpack) or vehicular radio and replaced the Larkspur Station Radio (SR) A13 SR C13 and other HF radios in ...
As an "all-band" transceiver, the TS-2000 offers a maximum power output of 100 watts on the HF, 6 meters, and 2 meters bands, 50 watts on 70 centimeters, and, with the TS-2000X or the optional UT-20, 10 watts on the 1.2 GHz or 23 centimeters band. The (American version) radio's main receiver covers 30 kHz through 60 MHz, 142 MHz through 152 MHz ...
High frequency (HF) is the ITU designation [1] for the band of radio waves with frequency between 3 and 30 megahertz (MHz). It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters (ten to one hundred meters).
Moxon antenna for the 20-meter band.The antenna is the faint rectangle of wires held in tension by the bent X-shaped support frame. Moxon antenna for the 2-meter band. The Moxon antenna or Moxon rectangle is a simple and mechanically rugged two-element parasitic array, single-frequency antenna. [1]
The 14-30 has a rating of 30 A, and an L-shaped neutral blade. The 14-50 has a rating of 50 A, and a straight neutral blade sized so that it does not mate with 14-30 connectors. NEMA 14-50 devices are frequently found in RV parks, since they are used for "shore power" connections of larger recreational vehicles.
