RAC Ontario Sections Bulletin for April 29, 2023
This is V_3___, Official Bulletin Station for Radio Amateurs of Canada
with this week's bulletin.

2.  FCC Proposes Changes to 60-Meter Band

The FCC issued a Notice of Proposed Rulemaking (NPRM) on April 21, 2023,
that deals with the 60m band. In a prior petition, ARRL urged protecting the
existing use of the band by amateurs when adding a new allocation adopted internationally.
Currently, radio amateurs in the US have access to five discrete
channels on a secondary basis, limited to an effective radiated power (ERP) of 100 W PEP.
The FCC proposes to allocate 15 kHz of contiguous bandwidth between
5351.5 - 5366.5 kHz on a secondary basis with a maximum power of  9.15 W ERP. This
allocation was adopted at the 2015 World Radiocommunication Conference (WRC-15).
ARRL said that years of amateur radio experience using the five discrete
channels have shown that amateurs can coexist with primary users at 5 MHz.. "Neither ARRL,
nor, NTIA, is aware of a single reported instance of interference by a radio amateur
operating at 5 MHz to date."
The Commission wrote, "Finally, we note that Canada has essentially
implemented the same rules as ARRL has requested."
The FCC proposed to allocate the 15 kHz bandwidth, but stopped short of
making a proposal on whether the existing channels should remain allocated to amateur
radio and what the power limitations should be. They requested comments on their proposal.

3.  2023 Online Ham Bootcamp

The Nashua Area Radio Society's spring 2023 online Ham Bootcamp will be
held on Saturday, May 13, from 10 AM to 6 PM Eastern Time. Access to the session
via Zoom.

Ham Bootcamp includes a series of demonstrations and tutorials designed
to help newly licensed hams get on the air. Ham Bootcamp is also a great opportunity
for hams who are interested in seeing what the hobby has to offer.

You can register for Ham Bootcamp at:

4.  Indian Researchers Develop Micro-Supercapacitor

Scientists in India say that they have created the smallest
micro-supercapacitor to date, developing it out of two-dimensional materials: graphene and molybdenum
This is considered significant because as electronic devices continue to
shrink their energy storage devices must be just as small. Supercapacitors are considered
ideal for this task because they not only store energy but can handle the kind of rapid
charge-discharge cycles beyond the ability of conventional chemical batteries.

Researchers used two-dimensional materials for the
ultramicro-supercapacitor because they are semiconductors. Each of the multi-layer electrodes acts as a
field-effect transistor.  The tiny device has a remarkably high capacitance and an easy ability to
integrate with electronic chips because of its use of a gel electrolyte instead of a
liquid.  Their next challenge is to create devices out of other two-dimensional
materials in an attempt to boost capacitance even further.

This concludes this week's bulletin. Does anyone require repeats or
Hearing none, This is V_3___ returning the frequency to net control.

Bulletin sent from Official Bulletin Manager VA3PC
If you go to the Nashua Area Radio Society's Bootcamp website, it says it's only open to people of the American persuasion.   I emailed their Bootcamp administrator re signing up or getting access to the recording.   She said she thought Canadians were welcome.  When I brought to her attention the restrictions listed on their own website, she hasn't replied, in over a week now.  I take from her silence that we Canadians need not apply.

Too bad, their previous Bootcamp received a rave review in QST.  It would have been nice to experience it, possibly in preparation for doing something like that here.
