+T2B – VHF/UHF operating practices: FM repeater, simplex, reverse splits; Access tones: CTCSS, DTMF; DMR operation; Resolving operational problems; Q signals 
+
+- [[T2B01]] (C)
+How is a VHF/UHF transceiver’s “reverse” function used? 
+	- A. To reduce power output
+	- B. To increase power output
+	- C. To listen on a repeater’s input frequency
+	- D. To listen on a repeater’s output frequency
+
+- [[T2B02]] (D)
+What term describes the use of a sub-audible tone transmitted along with normal voice audio to open the squelch of a receiver? #card
+	- A. Carrier squelch
+	- B. Tone burst
+	- C. DTMF
+	- D. CTCSS
+
+- [[T2B03]] (A)
+Which of the following describes a linked repeater network? #card
+	- A. A network of repeaters in which signals received by one repeater are transmitted by all the repeaters in the network
+	- B. A single repeater with more than one receiver
+	- C. Multiple repeaters with the same control operator
+	- D. A system of repeaters linked by APRS
+
+- [[T2B04]] (D)
+Which of the following could be the reason you are unable to access a repeater whose output you can hear? #card
+	- A. Improper transceiver offset
+	- B. You are using the wrong CTCSS tone
+	- C. You are using the wrong DCS code
+	- D. All these choices are correct
+
+- [[T2B05]] (C)
+What would cause your FM transmission audio to be distorted on voice peaks? #card
+	- A. Your repeater offset is inverted
+	- B. You need to talk louder
+	- C. You are talking too loudly
+	- D. Your transmit power is too high
+
+- [[T2B06]] (A)
+What type of signaling uses pairs of audio tones? #card
+	- A. DTMF
+	- B. CTCSS
+	- C. GPRS
+	- D. D-STAR
+
+- [[T2B07]] (C)
+How can you join a digital repeater’s “talkgroup”? #card
+	- A. Register your radio with the local FCC office
+	- B. Join the repeater owner’s club
+	- C. Program your radio with the group’s ID or code
+	- D. Sign your call after the courtesy tone
+
+- [[T2B08]] (A)
+Which of the following applies when two stations transmitting on the same frequency interfere with each other? #card
+	- A. The stations should negotiate continued use of the frequency
+	- B. Both stations should choose another frequency to avoid conflict
+	- C. Interference is inevitable, so no action is required
+	- D. Use subaudible tones so both stations can share the frequency
+
+- [[T2B09]] (A)
+Why are simplex channels designated in the VHF/UHF band plans? #card
+	- A. So stations within range of each other can communicate without tying up a repeater
+	- B. For contest operation
+	- C. For working DX only
+	- D. So stations with simple transmitters can access the repeater without automated offset
+
+- [[T2B10]] (A)
+Which Q signal indicates that you are receiving interference from other stations? #card
+	- A. QRM
+	- B. QRN
+	- C. QTH
+	- D. QSB
+
+- [[T2B11]] (B)
+Which Q signal indicates that you are changing frequency? #card
+	- A. QRU
+	- B. QSY
+	- C. QSL
+	- D. QRZ
+
+- [[T2B12]] (A)
+What is the purpose of the color code used on DMR repeater systems? #card
+	- A. Must match the repeater color code for access
+	- B. Defines the frequency pair to use
+	- C. Identifies the codec used
+	- D. Defines the minimum signal level required for access
+
+- [[T2B13]] (B)
+What is the purpose of a squelch function? #card
+	- A. Reduce a CW transmitter's key clicks
+	- B. Mute the receiver audio when a signal is not present
+	- C. Eliminate parasitic oscillations in an RF amplifier
+	- D. Reduce interference from impulse noise
