If you own an older FlexRadio (1000 to 5000 models), check out Darrin, KE9NS' free firmware upgrades for these & software enhancements for PowerSDR. It turned my "ancient" Flex-1500 SDR into a new transceiver will all kinds of internet connectivity & data sources feeding its various display screens. He provides YouTube videos explaining how to operate your supercharged Flex SDR using his enhancements.

My KiwiSDR 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 a Softrock RXTX, Flex-1500, RTL-SDR, KiwiSDR & FT-857D using a 50 m (in perimeter) horizontal wire (Delta) loop @ 6 m AGL.

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. Last week it had "only" four independently operating web browser controlled receivers you could share via internet (SDR.hu) or home/mesh network. But this week we can have eight separate 10 kHz to 30 MHz receivers (14 bit) because of its amazing field programmable gate array (FPGA). In early 2016, the KiwiSDR went from being a gleam in John's eye, to a Kickstarter compaign, to something selling thousands of units. Mine is #1872, bought "way back" in mid-2017.

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. It creates an outdoor private hotspot & any other authorized Wi-Fi devices (within 50 m of my house) can connect back to the basement router.
 
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).
 
Bought 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 the eclipse.
 
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.
Tag also created the new free "GridTracker" program that interfaces with WJST-X & various contest logger programs, QRZ, the WSPRnet & PSKReporter.
