Added new references & resources to the All Things Digital section for my next TCA column
article Build an Arduino Analog SDR Control Gadget 2 (ATD026).
Here's an excellent, very informatiive & concise
Amateur Radio podcast set called "Foundations of Amateur Radio" by Onno Benschop, VK6FLAB: http://tinyurl.com/hen7a6u
for podcasts (usually < 5 mins) are also available. Despite variations in operating rules for different parts of the world,
radio basics remain the same.

The Georgian Bay ARC hosts an updated online Canadian Amateur Radio
Basic Qualifications course. This is ideal for those who can't attend physical classes for whatever reason, and/or don't have
a local radio club. N
ote: You no longer need to learn the Morse code becausee it was dropped, years ago, as a requirement.
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.

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.
