The Georgian Bay ARC is hosting an updated online course for the Canadian Amateur Radio Basic Qualifications.
This is an ideal course for those who can't attend physical classes for whatever the reason, or don't have a radio club in their local
area. We "hams" don't need no steekin' Internet, Wi-Fi, or landlines to communicate around the world!
Note: You no longer need
Morse code as it was dropped as a requirement from the Canadian Amateur Radio course years ago.

Added new QRSS (30
metres) grabber web page to my growing list of 24/7 fully-automatic signal/telemetry collecting pages: QRSS Grabber. The page updates
every 10 minutes and shows the last two hours of activity.

Added new references & resources to the All Things
Digital section for my next TCA column article Build a 10 MHz External Reference Device Part 2 (ATD025).
From W2YG Software
: RMS Express now has a 'KISS' mode WL2K packet 'Setup' option to provide a direct route
to the packet engine interface (via TCP).This feature can be used for soundcard access using the latest version of the UZ7HO
SCM described in UZ7HO-SoundModem-Installation
by Dick, W6CCD.

Now receiving telemetry from Amteur Radio
satellite PSAT (NO-84) on 145.825 MHz (FM mode). PSAT is an APRS/PSK-31 digipeater designed at the U.S. Naval Academy, and will be
joined by other such "birds", in the near future. See WB4APR's PSAT
info page for more. Telemetry received by ground stations
is uploaded to the findU PSAT
page (mine is listed under "VA3ROM"). Currently, the APRS digipeater is off.

Finished setting up my second RTL-SDR dongle and laptop. Now now I'm
porting the ISS digipeated APRS packets (145.825 MHz, FM) as a satellite gateway (SGATE) to the APRS-IS and ARISS usingUISS, and the FUNcube (AO-73) BPSK flight telemetry (145.935 MHz, USB) to the FUNcube Warehouse. Both datasets are uploaded using
my amateur radio callsign "VA3ROM", but non-hams and other groups can also contribute and upload data by using an alias.
2 m "reactive turnstile" antenna with LNA (powered by a bias-T) is connected with 15 m of RG-6 to another LNA (powered directly)
then to a signal splitter. One output is for the ISS/AO-73 "birds" feeding one RTL-SDR dongle and laptop, the
second for the NOAA APT
and Meteor LRPT weather satellites feeding another RTL-SDR dongle and laptop.
Everything is powered though
a battery backup UPS for 24/7, fully automatic operation, using Startup Delayer
to handle program reloading after unexpected
shutdowns or reboots happen.
