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 is inflammation and swelling of the lining membranes of the sinuses. This is commonly caused by bacterial or viral infections or blockage of the sinus openings by thickened mucosa called polyps. Symptoms of sinusitis include facial pain or pressure, nasal obstruction, discolored nasal drainage, loss of sense of smell, and headaches. The majority of patients with sinusitis can successfully be treated with antibiotics or other medications, treatment of allergies or environmental control.
