Portable SDR with built-in antenna analyzer

pSDR

As I read the web site and watch the embedded videos, I am of course interested in the technology described – but perhaps even more interesting is the age of the ham involved. We often hear about the “graying” of ham radio and I’ll be the first to agree with those who say that the hobby…

NOAA 15 satellite pass received

Screenshot of SDR# during reception

NOAA 15 made a pass over my QTH this morning with a maximum elevation of 35 degrees. Not ideal but I was surprised to start receiving the satellite’s signal on the very minute of its rise above the horizon. At this point, it was being received 2.5 kHz above the onboard transmit freq of 137.620 MHz…

QFH?

“QFH?” means “Do you have a quadrifilar helicoidal?” As of this morning I am “QFH” and ready to receive NOAA weather satellites – in fact, I already have with the antenna indoors and propped against a wall. The resulting image is nothing to write home about but I have no doubt that once placed outside…

Am I hearing you on 20 meters?

Thanks to a comment from Owen (no callsign noted) on a prior post, I was able to fairly easily get CW Skimmer to run based on inputs from the FCD+. This is the page that did it – thanks Owen. I say “fairly” easily because there are four places to input a desired frequency in…

Initial impressions of the new FunCube Dongle Pro+

20m last night on FCD Pro+ and SDR#

Only three days after placing the order, a new (and much improved) FunCube Dongle Pro+ arrived on my doorstep from the UK. I previously had one of the original FCD’s – a non “plus” model – but quickly lost interest in it because it did not offer access to HF frequencies. The new version covers…

Leaning toward a Flex-1500

F1500

Over the years, I’ve tinkered with the poor man’s SDR – primarily SoftRocks and various “dongles”. They’re fun, educational and well worth what little money they cost. I’ve also considered adding Elecraft’s panadapter to my K3-based shack. Both of those paths seem to be leading to one much more efficient place – an SDR radio with real functionality…
