Can a transmitter or in this case a repeater transmit both ctcss and dcs be transmitted at the same time? In this case what I'm trying to achieve is using the dcs as an identifier being decoded and used to display what repeater was being used while the ctcss tone is used to open the squelch on the receivers.his is because CTCSS is just a frequency and two sources of the same frequency won't interfere much with each other. However, DCS being a digital code might interfere with another radio transmitting the same code such that the 3rd radio won't hear anyone.
Sometimes, a cold may cause swelling in the sinuses, hollow spaces in your skull that are connected to each other. The swelling can prevent the flow of mucus. This can lead to a sinus infection. If you have pain around your face and eyes -- and thick yellow or green mucus for more than a week -- see your doctor.
Sinusitis, also known as a sinus infection or rhinosinusitis, is inflammation of the sinuses resulting in symptoms. Common signs and symptoms include thick nasal mucus, a plugged nose, and pain in the face. Other signs and symptoms may include fever, headaches, poor sense of smell, sore throat, and cough. The cough is often worse at night. Serious complications are rare.
