This is is followup to our discussion at the MWL just past regarding measuring sun noise / moon noise. The key to getting an accurate measurement is in having sufficient bandwidth of the sampled signal, whether the technique used is…

I have been having good success with my 630m station performance for both transmit and receive, although as previously mentioned I want to improve my transmit antenna and have plans to do so in short order. I had originally planned…

Above is a map of the WSPR stations that I have received over the past 2 weeks. Because the WSPRnet site map will only display data for up to 24 hours, I used the aprsinfo site to generate this map….

I still have a very basic antenna system here both for Rx and Tx, and I have substantial improvements planned, but even so I have made some improvements that are interesting from a technical standpoint and have also significantly improved…

This was a busy week, but I managed to work a few more stations after my first contact with Wayde, K3MF, which I described in the prior blog. Since I worked Wayde, all of my subsequent contacts have been digital,…

In a recent blog post I discussed tuning my short 75 foot (15 ft vertical and 60 ft horizontal) Inverted L with my BC306-A variometer. So yesterday I set up a sked and worked K3MF on 473.6 kHz, using CW….

  You can barely see the inverted L running between the two towers in the photo above.  In a prior blog, I characterized its receive performance, which was worse than a lower and shorter inverted L, and worse than both…

I. INTRODUCTION There are 10 Amateur Bands between 50 MHz and 10 GHz inclusive, with widely differing propagation characteristics. There are currently (as of 2-20-18) 5 slow JT modes and 3 fast JT modes, the latter allowing 15 second or…
