ARRL New Licensees Privileges Request!

ARRL Requests Expanded HF Privileges for Technician Licensees

02/28/2018ARRL has asked the FCC to expand HF privileges for Technician licensees to include limited phone privileges on 75, 40, and 15 meters, plus RTTY and digital mode privileges on 80, 40, 15, and 10 meters. The FCC has not yet invited public comment on the proposals, which stem from recommendations put forth by the ARRL Board of Directors’ Entry-Level License Committee, which explored various initiatives and gauged member opinions in 2016 and 2017.

“This action will enhance the available license operating privileges in what has become the principal entry-level license class in the Amateur Service,” ARRL said in its Petition. “It will attract more newcomers to Amateur Radio, it will result in increased retention of licensees who hold Technician Class licenses, and it will provide an improved incentive for entry-level licensees to increase technical self-training and pursue higher license class achievement and development of communications skills.”

Specifically, ARRL proposes to provide Technician licensees, present and future, with phone privileges at 3.900 to 4.000 MHz, 7.225 to 7.300 MHz, and 21.350 to 21.450 MHz, plus RTTY and digital privileges in current Technician allocations on 80, 40, 15, and 10 meters. The ARRL petition points out the explosion in popularity of various digital modes over the past 2 decades. Under the ARRL plan, the maximum HF power level for Technician operators would remain at 200 W PEP. The few remaining Novice licensees would gain no new privileges under the League’s proposal.

ARRL’s petition points to the need for compelling incentives not only to become a radio amateur in the first place, but then to upgrade and further develop skills. Demographic and technological changes call for a “periodic rebalancing” between those two objectives, the League maintains.

“There has not been such a rebalancing in many years,” ARRL said in its petition. “It is time to do that now.” The FCC has not assessed entry-level operating privileges since 2005.

The Entry-Level License Committee offered very specific, data- and survey-supported findings about growth in Amateur Radio and its place in the advanced technological demographic that includes individuals younger than 30. It received significant input from ARRL members via more than 8,000 survey responses.

“The Committee’s analysis noted that today, Amateur Radio exists among many more modes of communication than it did half a century ago, or even 20 years ago,” ARRL said in its petition.

Now numbering some 378,000, Technician licensees comprise more than half of the US Amateur Radio population. ARRL said that after 17 years of experience with the current Technician license as the gateway to Amateur Radio, it’s urgent to make it more attractive to newcomers, in part to improve upon science, technology, engineering, and mathematics (STEM) education “that inescapably accompanies a healthy, growing Amateur Radio Service,” ARRL asserted.

ARRL said its proposal is critical to developing improved operating skills, increasing emergency communication participation, improving technical self-training, and boosting overall growth in the Amateur Service, which has remained nearly inert at about 1% per year.

The Entry-Level License Committee determined that the current Technician class question pool already covers far more material than necessary for an entry-level exam to validate expanded privileges. ARRL told the FCC that it would continue to refine examination preparation and training materials aimed at STEM topics, increase outreach and recruitment, work with Amateur Radio clubs, and encourage educational institutions to utilize Amateur Radio in STEM and other experiential learning programs.

“ARRL requests that the Commission become a partner in this effort to promote Amateur Radio as a public benefit by making the very nominal changes proposed herein in the Technician class license operating privileges,” the petition concluded.

The uBITX is a general coverage HF SSB/CW transceiver kit with features you NEED for operating ease, convenience and versatility. If works from 3 MHz to 30 MHz, with upto 12 watts on SSB and CW with a very sensitive receiver. It features digital tuning, dual VFOs, RIT, CW Keyer and more.  The uBITX is a general coverage HF SSB/CW transceiver kit with features you NEED for operating ease, convenience and versatility. It works from 3 MHz to 30 MHz, with upto 12 watts on SSB and CW with a very sensitive receiver. It features digital tuning, dual VFOs, RIT, CW Keyer and more.

Operating

The uBITX is a joy to operate. Press the tuning control to access all the features. Dual VFOs, RIT, CW speed, sideband selection. etc. are all accessible from a single menu. The transceiver automatically selects the proper sideband for you (you can override it too).

Technical Specifications

The uBITX is an understandable radio. The complexity is kept to a minimum so you can always repair and make changes if you so desire.

The the uBITX has a carefully thought out operator interface. The tuning knob features a number of menu options on a click. From RIT, to dual VFOs, to the keyer and many more featuers are all accessible from the tuning knob by simply tapping on it.There are intelligent defaults everywhere (these are easily overriden). Example : below 10 MHz, it auto-selects LSB and vice versa. To operate CW, you just press the morse key.

Architecture The uBITX uses upconversion to the first IF of 45 MHz. This eliminates the need for a large number of band pass filters, keeping the design simple and virtually image free. The roofing filter at 45 MHz is 15 KHz wide. The signal is then down-converted to 12 MHz where a low ripple SSB filter with 8 crystals is used to provide a sparkling audio.

The transmitter has push-pull PA using two IRF510s for a clean output. The low cost IRF510s are not  a bother to replace should you ever blow them up.

Receiver :

  • Sensitivity a 0.2uv signal is clearly audible
  • Selectivity 2.4 KHz,  low ripple SSB filter with 8 crystals
  • RIT (Receiver Incremental Tuning)
  • Continuous coverage from 500 KHz to 30 MHz
  • Sideband selection
  • Dent-less encoder tuning. Tunes with larger step rates when tuned quickly

Transmitter

  • More than 10 watts upto 10 MHz, 7 watts upto 21 MHz, 2 watts on 28 MHz
  • CW transmit with the built-in keyer
  • Uses   IRF510s  x 2 as PA and  2N3904 x 4 drivers in push-pull mode for low distortion transmission. Blown IRF510 are inexpensive to replace

Raduino Features

This is a small board with an Si5351 clock generator, an Arduino Nano and a 16×2 LCD display. It plugs into the main radio board. The software that controls the radio is written in Arduino’s C langauge.

All the features are available implemented in Raduino software. The menus are accessible by pushing the button on the tuning encoder. You can add more features by hacking through the open source code available on https://github.com/afarhan/ubitx

  • Dual VFOs
  • RIT
  • Manual override of LSB/USB selection
  • CW Keyer Speed and tone selection

September Meeting Program

Come join us for an interesting program at our September’s meeting at the Jefferson City Library. September 28th, 2017.

WSPRNET 

we’ll be covering details of equipment used, software, antennas, computers, why it’s helpful, ways to use it! Get ready for another tools to use with Amateur Radio

WSPR (pronounced “whisper”) stands for “Weak Signal Propagation Reporter”. It is a computer program used for weak-signal radio communication between amateur radio operators. The program was initially written by Joe Taylor, K1JT, but is now open source and is developed by a small team. The program is designed for sending and receiving low-power transmissions to test propagation paths on the MF and HF bands.

WSPR implements a protocol designed for probing potential propagation paths with low-power transmissions. Transmissions carry a station’s callsign, Maidenhead grid locator, and transmitter power in dBm. The program can decode signals with S/N as low as -28 dB in a 2500 Hz bandwidth. Stations with internet access can automatically upload their reception reports to a central database called WSPRnet, which includes a mapping facility.

Sun Unleashes Monster Solar Flare, Strongest in a Decade

Thanks to Dan W4DOD for the info below.
The Tennessee Phone Net on 3980 was wiped out this morning by this solar event.

Early this morning (Sept. 6), the sun released two powerful solar flares — the second was the most powerful in more than a decade.

At 5:10 a.m. EDT (0910 GMT), an X-class solar flare — the most powerful sun-storm category — blasted from a large sunspot on the sun’s surface. That flare was the strongest since 2015, at X2.2, but it was dwarfed just 3 hours later, at 8:02 a.m. EDT (1202 GMT), by an X9.3 flare, according to the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center (SWPC). The last X9 flare occurred in 2006 (coming in at X9.0).

According to SWPC, the flares resulted in radio blackouts: high-frequency radio experienced a “wide area of blackouts, loss of contact for up to an hour over [the] sunlit side of Earth,” and low frequency communication, used in navigation, was degraded for an hour.
