Technician Class Series – Repeaters


Hello everybody and welcome back to Everything Hamradio! Today we are going to continue our series on the Technician Class License Question Pool! Today we will be talking about Repeaters.

As always, the correct answers will be in bold. I also recommend that you only read the correct answers when studying for your test. If you do this, when you take your test and you see a question, there will be a better chance that the correct answer will jump out at you easier. Some say that this approach is kind of like cheating, but the way that I see it, you will always be learning something in this hobby and you don’t have to know everything there is to know about the hobby to get your license.

If you would like to purchase a copy of the Technician Class study book, written by Gordon West, WB6NOA with Eric P. Nichols, KL7AJ, that this series is loosely based around, below is a link to it.

Let’s move on to the good stuff, shall we?


T1F09 What type of amateur station simultaneously retransmits the signal of another amateur station on a different channel or channels?

  1. Beacon station
  2. Earth station
  3. Repeater station
  4. Message forwarding station

The two keywords in this question is “simultaneously retransmits.” If you look at your options to this questions the answer should just right out at you, if you don’t over think it to much, even if you don’t know anything about radios. When you hear something and say it again, what are you doing? You are repeating it.

§97.3 Definitions.

(a) The definitions of terms used in part 97 are:

(40) Repeater. An amateur station that simultaneously retransmits the transmission of another amateur station on a different channel or channels.

T1D07 What types of amateur stations can automatically retransmit the signals of other amateur stations?

  1. Auxiliary, beacon, or Earth stations
  2. Auxiliary, repeater, or space stations
  3. Beacon, repeater, or space stations
  4. Earth, repeater, or space stations

97.113   Prohibited transmissions

(d) No amateur station, except an auxiliary, repeater, or space station, may automatically retransmit the radio signals of other amateur station.


T4B11 Which of the following describes the common meaning of the term “repeater offset”?

  1. The distance between the repeater’s transmit and receive antennas
  2. The time delay before the repeater timer resets
  3. The difference between the repeater’s transmit and receive frequencies
  4. Matching the antenna impedance to the feed line impedance

The offset of a repeater is the difference in frequency between the input and output frequencies. For example, on 2M repeaters, the offset is 600 kHz, on 70cm the offset is 5 MHz. For example, our local 2M repeater here has an output of 145.490 with a negative offset. The input frequency is 144.890. Another 2M repeater here, has an output of 147.220 and an input of 147.820. On the two meter band, there is both a negative and positive offset. If the repeater is 147.000 or less, it is a negative offset. It it is 147.000 or above it has a positive offset. Did you catch that? I put 147.000 on both. The reason being is that if you have a repeater on 147.000 you can have either a positive or a negative offset. It is the choice of the owner and/or coordinator as to which it is.

T2A01 What is the most common repeater frequency offset in the 2 meter band?

  1. Plus 500 kHz
  2. Plus or minus 600 kHz
  3. Minus 500 kHz
  4. Only plus 600 kHz

As we talked about on the previous question, the offset on 2m is 600 kHz and it can go up or do, so the only possible answer to the question is B. Plus or Minus 600 kHz.


T2A03 What is a common repeater frequency offset in the 70 cm band?

  1. Plus or minus 5 MHz
  2. Plus or minus 600 kHz
  3. Minus 600 kHz
  4. Plus 600 kHz

I have been a ham now for better than 15 years, and I just learned something new. It happens quite often when I am writing blog posts about things. I had always been taught that on the 70 cm band, the offset was always positive. However, according to this question from the FCC Question pool is can be either. So, as long as you remember that the 70 cm offset is 5 MHz, your wont have any problems with this question since there is only one possible answer.


T2B04 Which of the following common problems might cause you to be able to hear but not access a repeater even when transmitting with the proper offset?

  1. The repeater receiver may require an audio tone burst for access
  2. The repeater receiver may require a CTCSS tone for access
  3. The repeater receiver may require a DCS tone sequence for access
  4. All of these choices are correct

Radios today have a feature in them called automatic offset. This is great when it comes time to dial in a repeater, but one of the most common things that new hams especially forget about is the tone for the repeater. Some new radios have a function that will find the tone for you, but it is not on as a default. Basically what it does when you key up is to scan the tones until it keys up the repeater. Sometimes this can take a little while so it is not a normal on thing because, unless I’m mistaken, it does it every time you key up. As far as what type of tone activates the repeater, that all depends on the repeater owner, it could be a audio tone burst, like a DTMF code, it could be a CTCSS tone, or is could be a DCS tone, normally found in newer model repeaters. So the answer to this question is, All of these choices are correct.


T2B02 What is the term used to describe the use of a sub-audible tone transmitted with normal voice audio to open the squelch of a receiver?

  1. Carrier squelch
  2. Tone burst
  3. DTMF
  4. CTCSS


T2A09 What brief statement is often transmitted in place of “CQ” to indicate that you are listening on a repeater?

  1. The words “Hello test” followed by your call sign
  2. Your call sign
  3. The repeater call sign followed by your call sign
  4. The letters “QSY” followed by your call sign

Calling CQ is normally used on HF or SSB VHF/UHF. On Repeaters, all you need to say is your call sign. You can go one step further and say your call sign followed by “monitoring” or something like that, but you only have to say your call sign. If you say something else that just your call sign, you will need to make sure that you clear if you don’t talk further to make sure that you stay compliant to the 10 min/end of QSO rule.


T1A08 [97.3(a)(22)] Which of the following entities recommends transmit/receive channels and other parameters for auxiliary and repeater stations?

  1. Frequency Spectrum Manager
  2. Frequency Coordinator
  3. FCC Regional Field Office
  4. International Telecommunications Union


T1A09 [97.3(a)(22)] Who selects a Frequency Coordinator?

  1. The FCC Office of Spectrum Management and Coordination Policy
  2. The local chapter of the Office of National Council of Independent Frequency Coordinators
  3. Amateur operators in a local or regional area whose stations are eligible to be auxiliary or repeater stations
  4. FCC Regional Field Office

§97.3 Definitions.

(a) The definitions of terms used in part 97 are:

(22) Frequency coordinator. An entity, recognized in a local or regional area by amateur operators whose stations are eligible to be auxiliary or repeater stations, that recommends transmit/receive channels and associated operating and technical parameters for such stations in order to avoid or minimize potential interference.


T1F05 What method of call sign identification is required for a station transmitting phone signals?

  1. Send the call sign followed by the indicator RPT
  2. Send the call sign using CW or phone emission
  3. Send the call sign followed by the indicator R
  4. Send the call sign using only phone emission

By the definition below you would think that the answer would be by phone emission only, but your would be wrong. FM Repeaters can use voice or CW to identify themselves, and a lot of times both. Repeaters that I have dealt with, if they have a voice IDer and you or someone else keys up while it is identify itself, when you unkey it will ID with a CW ID instead of voice. Some are even setup to use CW ID if the repeater is in use to not interrupt the QSO going on and then when it hasn’t been used for a while, it will use the voice ID.

§97.119 Station identification.

(b) The call sign must be transmitted with an emission authorized for the transmitting channel in one of the following ways:

(2) By a phone emission in the English language. Use of a phonetic alphabet as an aid for correct station identification is encouraged;
