WSJT-X has a slight problem that most users don't know about. It seems that even though the default setting
for saving *.wav audio files is set to "none", the program still merrily writes them to the hard drive until it's full &
"dies". See my short article about a semi-fix.
FT8Call by KN4CRD is a new program inspired by WSJT-X & other weak-signal
programs. It has created much controversy because of the use the root name but has no relationship to the original. But for better
or for worse, FT8's phenomenal "overnight" success has rocked the radio world to its core & this will lead to more imitation
& innovaton as the solar cycle slowly winds its way to a 2020 minima.

If you own an older FlexRadio
(1000 to 5000 models), check out Darrin, KE9NS' free firmware upgrades for these & software enhancements for PowerSDR.
He provides YouTube videos explaining how to operate your supercharged Flex SDR using his enhancements.

MyKiwiSDR is on the SDR.hu website & it wasn't as hard as I thought it would be. Look or search for "VA3ROM" near
the bottom of the ever growing receiver list. Also check out the latest feature using multiple KiwiSDR receivers to direction find
& locate transmitters using TDoA. There's also a very nice Google Maps SDR display you can use to view receiver details &
select any to listen to & control.
Got a new IC-7300 yesterday & am busy learning how to use it. It was easy enough
to flash the firmware with the latest upgrades, then set it up for WSJT-X & WSPR band hopping receive mode. All transceiver
control & audio is via a single USB cable, plus it has a nice & large & colourful data display with touch screen control.
The deep discount sale price, free shipping & $100 USD Icom rebate made it too much of a good deal to pass up! It's
connected to a five port antenna active multicoupler (Cross Country Wireless) & am comparing it to various radios &

The lastest KiwiSDR firmware update from John Seamons, KF6VO, has taken this receiver
to new heights of flight for an inexpensive direct radio frequency sampling (DRFS) radio. We can now have up to eight
separate 14-bit receivers of its amazing field programmable gate array (FPGA).

BloomSky had a great
deal on their STORM add-on units for their SKY1 & SKY2 person weather stations (PWS), so I got one to complete
a new PWS VA3ROM Thunder Bay. My old APRS/CWOP PWS is over 10 years old (LaCrosse) & going strong, except it lacks
the latest features. A SKY2 PWS was installed before last winter & it had no problems recharging on solar power & keeping
its Wi-Fi link (2.4 GHz) running even in the dead of winter. To create a solid link, I had to add a Wi-Fi repeater module because
the house router is in the basement with my radio shack.
FT8 is just a little over 1 year old & is dominating all
other Amateur Radio data modes, but its design team keeps right on tweaking the mode. Soon, an enhanced version will push its
weak-signal decoding level even deeper into the noise, but the really exciting thing is that a new 77 bit telemetry packet will
be added! Its supporting software (WSJT-X) v2.0 may be released in late 2018 or early 2019 (field testing will determine when).
a W6LVP aperiodic active (untuned with preamp) loop & currently conducting signal tests using WSPR & FT8. While
it receives up to 30 MHz, "magnetic" small loops are best for the lower bands from 40 m on down to 2200 m. Since I don't have
the room for large verticals or dipoles, this loop lets me go digital "down under" (literally). It should work nicely with my KiwiSDR.
The HamSci group has released its first peer reviewed published paper on the results of the August 2017 total solar
eclipse across America using various Amateur Radio data modes to create an ionospheric model before, during & after
RTL-SDR users check out the new free "Calico CAT" SDR# plugin created by "Tag" Loomis, N0TTL. It emulates
the Kenwood TS-2000 transceiver & allows you to use third-party programs such as WJST-X et al to control your RTL-SDR.
