Classify Radio Log For Free

A radio capable of operating in this band only is called HF radio. It may be a receiver, transmitter, or, transceiver (capable of both transmitting and receiving).

The radio spectrum is the part of the electromagnetic spectrum with frequencies from 3 Hz to 3,000 GHz (3 THz). Electromagnetic waves in this frequency range, called radio waves, are widely used in modern technology, particularly in telecommunication.

In the USA there is no longer any legal requirement to keep a log. Many HAMs log HF contacts often for use in contests or applying for various awards. There are a few contests and awards for VHF / UHF so some HAMs will keep a log for these types of contacts, but most don't.

The radio log must contain a summary of communications relating to distress, urgency and safety messages. The summary must include dates and times in Coordinated Universal Time (UTC), details of the vessels involved and their positions.

Modes: amplitude, angle, pulse. (2) The second symbol indicates the type of signal modulating the transmitter carrier. 0No modulation. 1 Digital. modulation, no subcarrier. 2Digital modulation. , modulated subcarrier. 3Analog modulation. (3) The third symbol indicates the type of transmitted.

Check for ankle instability with the drawer test, which assesses the talofibular ligaments. Hold the leg just proximal to both malleoli in one hand and grasp the foot in the other. Pull the foot forward while holding the leg still. Compare the injured and uninjured leg for abnormal talus movement.

(C) Representative knee radiograph of KL classification Grade 3, which demonstrates definite narrowing of joint space, moderate osteophyte formation, some sclerosis, and possible deformity of bony ends.

Based on the radiographic features, the severity of OA is given a grade from 0 to 4, with grade 0 signifying no presence of OA and grade 4 signifying severe OA.
