and now for something completely different? 😁 I was stimulated to think about ways to generate multiple-band FST4W and other precise digital modes with low spreading and (relatively) economic hardware

It looks like the RFzero could fit the bill, but there is one big problem and that is availability. This situation will probably not resolve in the near future so this unit is out if you don't own one

As some are very interested in that device, here a thread from the SDRplay groups.io https://groups.io/g/SDRPlayUsers/topic/97122706 Looking at for instance impedance matching of the Bodnar output to

People say they have missed the original WSPR Challenge so I wizzed up a look-alike. Not sure what I've missed by way of pages and functionality, the WayBack machine doesn't have the whole site so if

Hello All, With the great help of Tom, I got kiwirecorder and wsprdaemon running on a pi4 about a year ago. It's been rock solid since then, but I could use some help at the moment, as something broke

Hey Guys-- I got my WSPR/FST4W transmitter working this past weekend, it's a HackRF One with a Bodnar, and a ~1 watt amplifier (plus or minus 6 dB). I audio recorded a FST4W-300 file, and use GNURadio

When transmitting a FST4W message on f and a WSPR message also on f the decodes are consistently 2 Hz apart I tried this with a Hermes Lite v2 + SparkSDR Also with a RFZero with its own 2 sketches in

To continue the observations from John DF4UE (see thread on 2 Hz difference). Using wd-query on the Kiwi that has a RFZero supplied 66.66 MHz reference and GPS; local but over the air received KiWiSDR

Greetings ya'll After 6 weeks as a snowbird down at Orange Beach, I returned home to EN52wx and found my outdoor GPS antenna had also gone south when I was gone. Thus, I am now temporary running the K

Hi It is spring time - at least based on the calendar. Thus I have changed the schedule for OZ0RF from alternating between 20 m and 40 m to 3570007 Hz 5288607 Hz 7040007 Hz 10140107 Hz 14097007 Hz 181

I need to replace my KIWI fan. Does anyone know of a reliable model? John TI4JWC

1). Decoding .c2 files. According to its help menu, the 'wsprd' command which performs the decodes will accept .c2 files, but I have had no occasion to use them. You can experiment with the use of .c2

Hi, I would like to thank the author and the crew behind this wonderful open project. I tried WD on an I5 PC without problems, but rRunning the same configuration (max 7 jobs, standard decoding) on a

Some findings can be found here : https://dl1ycf.darc.de/hamlab.htm A site that also has good and deep information on the Hermes Lite v2 -- if we just had time for all things interesting -- Erwin

As we apparently have lost the KiWiSDR for new orders, this is some kind of alternative. It is open source, max 10 bands parallel for digimodes, 5W Tx. Ethernet connected. Clock Generator Synchronizat

I continue to test out Chinese manufacturing and assembly processes and still have a few 8-way Isolating-GPS Distribution boards (splitters) that I used as test cases available. These were entirely fa
