2. Straight Key Month is here
Calling all CW operators! January is the month to put your paddle in the drawer and dust off your straight key. It’s time for the 19th annual Straight Key Month, hosted by the Straight Key Century Club.
Throughout the month, you’ll be able to work K3Y stations in all US call areas. In addition, stations from regions within the IARU in Africa, Asia, Europe, North America, Oceania and South America will also be on the air. Taking their cue from the ARRL’s long-running Straight Key Night every January 1, the SKCC extends the event from the 2nd to the 31st of the month. Whether you’re a seasoned operator or just beginning your CW journey, you’ll find Straight Key Month to be a
great deal of fun while increasing your skills.
Information for this event can be found at skccgroup.com/k3y.

3. SCAMP Digital Mode Available in Fldigi
Simple Conversational Amateur Message Protocol (SCAMP) is a weak signal digital mode developed by Dr. Daniel Marks (KW4TI). Originally integrated with the RFBitBanger transceiver, SCAMP is now available for broader use through the Fldigi software suite. Like other weak signal propagation modes such as the popular FT8, SCAMP is an orthogonal frequency shift keying mode with a low symbol rate, forward error correction, and synchronous signaling. Unlike FT8 which has been designed to exchange signal reports, SCAMP must be able to communicate arbitrary messages that may be required in an emergency situation. [1]
For additional information, view KW4TI’s video presentation (youtube - open research institute) on SCAMP.

4. Single Crystal Electrode Lithium Ion Batteries Last a Long Time Researchers have been testing a new type of lithium ion battery that uses single-crystal electrodes. Over several years, they’ve found that the technology could keep 80% of its capacity after 20,000 charge and discharge cycles. For reference, a conventional lithium cell reaches 80% capacity after about 2,400 cycles. The researchers say that the number of cycles would be equivalent to driving about 8 million kilometers in an electric vehicle. This is within striking distance of having the battery last longer than the other parts of the vehicle. The researchers employed synchrotron x-ray diffraction to study the wear on the electrodes. One interesting result is that after use, the single-crystal electrode showed very little
degradation. According to reports, the batteries are already in production and they expect to see them used more often in the near future.
