On both 630m WSPR and 160m FT8 RX I have had great success using the FT817ND and the coax to my 2m big-wheel antenna. Just a mains earth was...

Something similar has been on before, but I make no apologies for this gentle reminder! Ferrite rods will work on TX as long as the ferr...

Now, I am no expert and this is based on personal experiences. As TX antennas ferrite rods should work. Indeed, my own tests at 80m, 40m...

In all, 46 stations were spotted on 80m WSPR using the ferrite rod antenna. Just one station spotted my 2.5W. There was far more 80m WSPR ac...

Jay W5OLF has kindly said keep the antenna. So, later in the week I shall try to resonate it on the correct WSPR and FT8 frequencies and try...

My page on ferrite rod TX antennas has been updated and some files added. There is now reference to the work of Giorgio Grisoni I2GSI fro...

It is some years since I tried this, but I remember being surprised how well this worked. As long as the ferrite is not saturated, a ferri...

For the first time in nearly two years (because of my brain bleed) I managed to get into our loft space today. Quite by chance I came acr...

OK, I only tried this with WSPR and with low power, but at my old QTH I had a good deal of success using a small ferrite rod as a TX anten...

Just for amusement, but with a slight hope it might work, I tried resonating a LW ferrite rod coil (about 3.5mH) at 8.97kHz to see how it m...

This morning I tried the ferrite rod antenna on 10MHz WSPR TX for an hour. As before, I mounted the ferrite rod VERTICALLY on the wooden des...

Vertical orientation today - good results on 40m WSPR TX This morning I tried to get a few more WSPR reports on 7MHz using my small ferr...
