Qrz what does it mean

Harmonic 1. Secondary RF emission that is a multiple of the fundamental emission. HF "High Frequency"; generally regarded as the band of frequencies between 1. Hz "Hertz"; a unit used to measure frequency. Iambic A method of Morse Code keying. A problem caused in the receiver of a radio by a nearby transmitter's spurious signals which may fall on or very near to the receiver's receive frequency.

In some cases, a perfectly clean transmitter i. Intermod which is close, but not necessarily right on, the receiver's frequency can cause the receiver to become less sensitive also known as "desense". A system by which most country's postal systems provide a coupon which can be purchased, and then used by a sender in any other country to obtain return mail postage.

This system allows you to provide return postage for those in another country, especially useful when you do not have access to that country's postage stamps or currency. J-Pole An antenna design that is relatively easy to assemble yourself.

Note: The basic J-pole design can be applied to any frequency, as long as measurements are proper for that frequency. Furthermore, a 2-meter J-pole will also resonate on the MHz 70 cm ham band, making for a reasonable dual-band antenna.

Kc "Kilocycle"; equivalent to KHz; regarded as an "old fashioned" way of describing frequency. Key Device used by hand to produce Morse Code; can contain either a single, vertically travelling arm see "Straight Key" or horizontally travelling paddles see "Paddles" that are used to make ground connection and produce the Morse Code.

Keyer Electronic device for sending Morse Code semi-automatically; connects to a key see above. Dits are sent by pressing one paddle [of the key], dahs sent by pressing the other one courtesy of VE3FFK. KHz See Hz K-Index A three hourly index of geomagnetic activity relative to an assumed quiet day curve for the recording site. LIon "Lithium-Ion". A type of rechargable battery commonly used with radio equipment. LOS "Loss of Signal" from a satellite; occurs when the satellite becomes "invisible" to the antenna as it goes below the horizon.

Lowfer One who experiments with radio communications at unusually low frequencies typically Meters, which is kHz and can be used under FCC Part Matchbox A device placed between a transmitter and an antenna to tune the circuit to resonance. Mc "Megacycle"; equivalent to MHz; regarded as an "old fashioned" way of describing frequency.

Medfer One who experiments with radio communications at low frequencies such as those on the edges of the AM broadcast band under FCC Part Paddles Short for "Morse Code Key", one that contains small paddles that are tapped in order to produce semi-automatic Morse Code when connected to a "keyer".

Patch Short for "Phone Patch". P type means it is doped with "free holes" electron depletion and the N type is doped with electrons. Of course by physics, the free holes and free electrons would like to neutralize each other.

A diode is formed with a P-N junction. PSK31 A digital mode which is rapidly growing in popularity; utilizes phase shift keying PSK which is transmitted at 31 baud speed.

PTT "Push to Talk"; a button on a microphone or on the side of a handheld radio which activates the transmitter. With regard to an antenna circuit, the Q has an inversely proportionate relationship to useable bandwidth with reasonable SWR. For example, an antenna with "high Q" will not provide a good SWR over a very wide range of frequencies.

Q-Signals Originally developed by CW Morse Code operators to make certain, frequently used phrases short and concise -- a sort of Morse Code "shorthand". In large scale situation, typically broken into an "incoming" and "outgoing" bureaus. Repeater A system consisting of at least one transmitter, one receiver, and a controller, which receives a signal on one frequency and retransmits it on another frequency. Repeaters are typically located in high locations so that they have greater coverage area.

Repeaters are most commonly used on the 2 meter and 70 centimeter bands. See also "Simplex Repeater". RF Burn A painful sensation felt when coming into direct contact with RF energy; can be dangerous when experienced with high levels of RF power. Rig Radio RIT "Receive Incremental Tuning"; a common feature on HF radios that allows the user to slightly change the receive frequency while leaving the transmit frequency the same.

RST "Readability, Strength, Tone"; a system by which a received signal quality is graded, and a signal report is given. A very high quality CW signal is "" pronounced "five nine nine" , and such a phone signal is "59" pronounced "five nine".

Inefficient, but useable, and they don't poke you in the ribs too badly either! RX Abbreviation for "receiver" or "receive". This term is normally used in the context of environments that frequently use repeaters.

Simplex Repeater A radio that has a digital audio store-and-forward relay system. Produces results similar to that of a conventional repeater.

Slug A short, cylindrical unit that is inserted into a Bird? Wattmeter or similar that allows the unit to read power watts for a particular frequency range. A slug always has a finite frequency range and a maximum power rating. By swapping out different slugs, the wattmeter can be used for many different frequencies and power ranges. QTG Will you send two dashes of 10 seconds each followed by your call sign? I am going to send two dashes of 10 seconds each followed by my call sign.

QTH What is your location? QTI What is your true track? QTJ What is your speed? QTL What is your true heading? QTO Have you left dock or port? I have left dock or port. QTP Are you going to enter dock or port? I am goin gto enter dock or port. I am going to communicate with your staion by means of the International Code of Signals. QTR What is the correct time? QTU What are the hours during which your station is open? QTX Will you keep your station open for further communication with me?

I will keep my station open for further communication with you. Here is the information you requested QUC What is the number of the last message you received from me?

QUG Will you be forced to land? I am forced to land immediately. QUH Will you give me the present barometric pressure? How is the tone of my transmission? What is the intelligibility of my signals? Is my transmission being interfered with? Are you ready for automatic operation? What is the strength of my signals? Can you hear me between you signals and if so can I break in on your transmission? Have you a doctor on board?

Shall I send each word or group more than once? Do you agree with my counting of words? This became clear to me after a bit of time to think, but it wasn't at all clear on initially jumping in. It helps to know the formal definitions of the codes used:.

The station is asking for new contacts from anyone. The station is asking for a calling station to repeat their callsign. Only a station which has already attempted to contact them should speak at this time. During contests, a popular station say DX has a pileup with lots of stations trying to make contact.

A station will often merely say QRZ for picking up someone from the pileup. Thus, in this I am agreeing with the previous answer but with the following comment. I believe that this method of saying QRZ is now so popular in this pileup situation that is, commonly done by many that it has actually changed the use of QRZ over the years from its original intent of not fully copying a call sign or questioning the caller to repeat his call sign.

Whether it is correct to use QRZ in this way -- makes no difference -- this is what people are doing. As said by other answerers, it's typically the station announcing 'I'm ready for more contacts at this time. It is kind of informal usage, as Kevid Reid mentioned, the official QRZ definition is 'who is calling me? The contest station will usually only use CQ if they're not getting responses. Typically, when a contest station says QRZ, you should reply by saying your callsign once , and quickly, especially if there is a pile-up.

It is considered very rude to repeat your callsign many times. One of the worst examples I've heard was after a DX station said QRZ, a station responded with their callsign and 'I know you're hearing me, just answer and I'll stop calling! This just causes more irritation to those trying to communicate, especially when the operator is talking over those who are in communication.

So best practice is to say your callsign once. If you're having trouble getting through, patience is the best way to get the contact. Just keep trying, saying your callsign once immediately after they say 'QRZ' Don't be discouraged if you hear stronger, clearer stations first.

They'll get serviced, and the station will get around to you.
