Updates
 
February 09, 2017
Added new reissued & revised SSTV articles from my past TCA columns for early 2016 to the All Things Digital section (ATD022 & ATD023 refers) & this completes the 4-part series. Since then the RTL-SDR USB dongle SDRs & SDR# DSP software has advanced so much in only 12 months I just can't imagine what the digital radio world will look like in 2020! Plus there is an amazing new crop of software add-ons (plugins) to go with.

Just spotted a 1/4 page blurb in the Feb. QST. Check out this totally cool Raspberry Pi project called PiGate.
 
Rewording made to paragraph in the BBHN article 'Webmail Access to Paclink' regarding port 80 conflicts (see All Things Digital section). Many newer Wi-Fi cards have built-in "hosted" or stand alone network support (a close "cousin" of mesh networks) along with regular hotspot capability (W7 to W10) & was enabling this feature on a new laptop when the confusing wording was spotted. There's an excellent Wikiweb article on testing for & enabling hosted networks.
 
Note: Both hosted and mesh networks have the ability to provide internet connectivity, if available, but they can also stand alone without it & act as intranet servers for everyone in the surrounding wireless area; Amateur Radio mesh networks have additional capabilties (BBHN and AREDN). A Wi-Fi "hotspot" can only provide internet connectivity when it's available else it can't function on its own. Subtle, but very important differences to know. But, I digress...
 
Anyone can now join your hosted wireless network using any wireless device (smartphone, tablet, et al) just provide your node's IP address & any required user name/password for emergency communications (EmComm) email access. Any extra web services can be either open access (i.e. for APRS using UI-VIEW's built-in web server) or private for EmComm use only. "Guest" account email access can be setup to allow "civilians" to send short message service (SMS) text only messages out of disaster areas when commercial comms are cut off. Both mesh & hosted email servers can piggyback the Winlink 2000 (WL2K) global radio email messaging system using a combination of HF/VHF radio message server (RMS) "gateway" stations & other available systems (internet "cloud", cellular, et al).

Many new links added to the All Things Digital section, so have a look.
 
If you enjoy reading about the history of technology from the late 1960's to the present, check out the Analog Devices Inc. newsletter Analog Dialogue. While it's written for engineers by engineers, there is "stuff" that even we "mortals" can understand & use in our radio/electronics hobby.

Added new link for the KE9NS website in the All Things Digital section. Darrin provides awesome support for the older Flex SDR series enahncing the features of PowerSDR. His latest release includes a firmware upgrade to enable 60 metre band transmit for IARU Region 1 users.

Happy New Year!
 
Added three new links: one to this page for Crag's Ham Radio Projects Links & the other two for NirSoft & FunCube (AO-73 cubesat) to the All Things Digital page.
 
I've been receiving & streaming AO-73 telemetry (PSK31 format) to the "warehouse" & will crack the top 100 list of active telemetry contributors in a month or so. I don't do  two-way digital comms because the antenna's preamp isn't a transmit through type, but many are active users & the "bird" was very popular over the the holidays.

Been actively conducting QRSS and WSPR very low power (QRPp) experiments for the past few months. I'm gearing up for the Solar Eclipse QSO Party in August 2017 for the total solar eclipse scheduled to cross the middle of the United States. Check out HamSci for more information.
 
I have a variety of outdoor antennas, but wanted to try my MFJ magnetic loop tuner indoors. It's setup for 40 metres using 8.5 metres of #8 insulated copper wire (stranded) hung on the north facing wall of my back bedroom & shaped into a vertical delta loop. A 15-metre length of RG58 feedline runs to the livingroom and my Flex-1500 SDR and quad-core laptop. While it's not a DX setup & mainly hears U.S. & Canadian stations, I did get several hits from a WSPR Puerto Rican station.
 
Added my new Jan-Feb TCA column QRSS CW: Part 1 (ATD027) to the All Things Digital section.
