  • QRP Notes and Definitions Page 1 Philosophy Practice QRSS
    QRP notes and definitions Page 1 QRP operation From Wikipedia, the free encyclopedia In amateur radio, QRP operation means transmitting at reduced power levels while aiming to maximize one's effective range while doing so. The term QRP derives from the standard Q code used in radio communications, where "QRP" and "QRP?" are used to request, "Reduce power", and ask "Should I reduce power?" respectively. The opposite of QRP is QRO, or high-power operation. Philosophy Most amateurs use approximately 100 watts on HF and 50 watts on VHF/UHF, but in some parts of the world, like the US, they can use up to 1500 watts. QRP enthusiasts contend that this is not always necessary, and doing so wastes power, increases the likelihood of causing interference to nearby televisions, radios, and telephones. A lot of Amateurs subscribe to the idea, use "the minimum power necessary to carry out the desired communications". The current record for a QRP connection is 1 µW for 1,650 miles on 10m. Practice There is not complete agreement on what constitutes QRP power. While most QRP enthusiasts agree that for CW, AM, FM, and data modes, the transmitter output power should be 5 watts (or less), the maximum output power for SSB (single sideband) is not always agreed upon. Some believe that the power should be no more than 10 watts peak envelope power (PEP), while others strongly hold that the power limit should be 5 watts. QRPers are known to use even less than five watts, sometimes operating with as little as 100 milliwatts or even less.

  • QRP Contesting and Dxing K6UFO - Mark “Mork” Aaker
    QRP Contesting and DXing K6UFO - Mark “Mork” Aaker QRP LOW Power HIGH Power “QRP” is an old telegraph signal: “lower your power.” QRP? = Can you lower your power? Today, the standard Amateur Radio meanings are : • QRP = 5 Watts or less transmitter power. • Low Power = up to 100 Watts, e.g., a “barefoot” radio. (up to 150 Watts in ARRL contests) • High Power “QRO”, from 100 W (or 150 W) up to the contest limit (1,500 W) or the country’s legal limit. Canada: 2,250 W PEP USA 1,500 W Japan: 1,000 W Italy: 500 W U.K.: 400 W Oman: 150 W How MUCH Power? • Total Energy Output of the Sun 10^26 W • Nuclear reactor 1 Gigawatt = 10^9 W • Shortwave Broadcast 1 Megawatt = 10^6 W • AM/FM radio Broadcast 50,000 W • Digital TV Broadcast 10,000 W • Amateur Radio 1,500 W • Microwave oven 1,000 W @ 2.45 GHz How little Power? • Amateur Radio 1,500 W – 100 W – 5 W • Christmas tree bulb 7 W – 5 W • CB Radio 4 W • LED Flashlight 3 W – 1W • Cell phone 2 W - 0.002 Watt • FRS radio 500 milliwatt • WiFi transmitter 100 milliwatt – 0.1 mW • Equivalent light output of a Firefly 1 mW It’s the Law! …as far as I can tell, no Amateur has ever been cited.

Challenge: Long distance communication with the power of flashlight batteries. 2. Simplicity: Most QRP equipment is a kit / homebrewed and is easy to operate User knows function of each component. 3. Nostalgia: Reliving the old days when contacts were made with primitive equipment and each contact was an achievement. Tino Zottola, VE2GCE, Aug 17, 2020 Definition QRP = “Reduce power“ QRP enthusiast’s goal ➔ Use minimum power possible to carry out the desired communications The difference between 100 watts and 1 watt is only 20 dB or (3.3 S units) • 5 Watts (max) CW /FT8 • 10 Watt (max) SSB QRPp (extreme QRP): Sub-watt region • Using 100 milliwatts, 10 milliwatts or 1 milliwatt Commonly used benchmark is ratio of distance / power • Montreal - Charleston, SC: 1000 miles with 1000 watts ➔ 1 mile / watt • Montreal - Charleston, SC: 1000 miles with 1 watt ➔ 1000 miles / watt • Montreal - Eastern Australia: 10000 miles with 1 watt ➔ 10,000 miles / watt • Montreal - Eastern Australia: 10000 miles with 0.001 watt ➔ 10,000,000 miles / watt Tino Zottola, VE2GCE, Aug 17, 2020 Operation QRP station can be implemented in one of three ways: 1. Regular transceiver with power dialed down to 1 to 10 watts 2. QRP transmitter + conventional receiver 3. QRP specific transceiver(*) *Many QRP specific transceivers use simple DCO receivers (i.e. less sensitivity than superhet).

  • Mfj-971 Qrp Portable Antenna Tuner
    MFJ-971 QRP PORTABLE ANTENNA TUNER GENERAL DESCRIPTION: The MFJ-971 is a compact 200-Watt portable tuner compatibly packaged with. MFJ QRP transceivers. The MFJ-971 is also a perfect mate for any of today's ultra-compact SSB radios. It provides a convenient cross-needle type SWR/Wattmeter and features a special user-selectable 6-Watt range for QRP operation. The T-match tuner covers 1.8-30 MHz and tunes almost any coax, wire, or balanced-feed type antenna (a 4:1 toroid balun is built in for balanced line). READING THE CROSS NEEDLE SWR INDICATOR: The MFJ-971 uses a cross- needle style meter to display FORWARD power, REFLECTED power, and SWR simultaneously. To read Forward Power, observe the FORWARD meter scale. To read Reflected Power, observe the REFLECTED meter scale. To read SWR, observe where the two needles cross. The corresponding red curve on the meter face displays your SWR reading. No "zero" or "sensitivity" adjustment is required with cross-needle SWR displays. POWER LEVELS: The FORWARD scale is calibrated from 0-300 Watts and the REFLECTED scale from 0-60 Watts. In the high-power range, read both scales directly (x 1). In the 30 Watt range, move the decimal point one place to the left (x 0.1). For QRP sensitivity (6-Watts FORWARD, 1.2-Watts REVERSE), you must perform a simple conversion to obtain actual power. You can convert in your head by moving the decimal point two places to the left and doubling the reading (ie. 300 W = 3.00 x 2 = 6 W).
