B 1 For best RF safety, where should the ends and center of a dipole antenna be located? This depends on the situation after the last contact is completed as well as the situation on the frequency in use. The first step will be to evaluate the filters with the nominal values specified in the design. In fact the mobile stations coverage area becomes that of the repeater. All the different things that make up this hobby culminate in contacting other persons with the same basic interest and, above all, the contacts made will contribute towards friendship and goodwill to each other.
It means that when Don Anderson of Summer Passage, for example, transmits his latest weather forecast, anyone who wants to can listen at the same time. Proper basic radio operating techniques, based on an understanding of half-duplex operation. The receiver is muted and has no access to the antenna when transmitting, thereby preventing the receiver from being overloaded by the transmitter signal and preventing a feedback loop between the receiver speaker and the transmitter microphone. But are they clear watts? You may want to add a surge supressor in parallel with it. B 3 Why should you wear a safety belt if you are working on an antenna tower?

This is done to ensure that transmission is not started by misinterpreting mobile flutter as the end of a transmission. Below the frequency is the RF spectrum frame around that frequency. The use of Citizens Band radio lingo, such as Handle , That's a , and the like is considered to be poor operating practice. B 2 The diode is an important part of a simple power supply. High Power can also cause problems when used in the vicinity of other repeaters.
Gqrx can then stil be used to view the real time spectrum. Our rig architecture is triple-conversion with IF's at However, there is a case for using Q-Codes on telephony if the operators do not share a common language. Press the 'CL' button — the channel knob now goes into frequency changing — and turn the knob in tiny steps. There are cases where available bandwidth make this practice impractical. Will you keep your station open for further communications with me? As a prelude to becoming a Ham, people should serve a basic training as a Short-wave Listener, both on the Broadcast bands and Amateur Radio bands, and have some knowledge which will help them considerably when going on the air for the first time.
