 It occurs to me that my earth-electrode "antenna" in the ground should work well on 2200m RX. Apart from my CW/QRSS beacon, I hav...

One of my Facebook memories today was this photo of my 2200m tests. Apart from a very brief TX last year I have not been on that band on TX ...

Whilst looking through some old photos I came across this photo from 2012 of my 136kHz beacon. With just microwatts ERP the signal was copie...

Last week I mentioned that I had, by accident, found my 136kHz CW beacon. I also found my battery operated E-field probe which fits on a car...

  This morning I was looking for the original WISPY receiver. I opened the case and found this! It is the 136kHz beacon I used about 8 years...

Before moving to the current QTH about 7.5 years ago, I did some tests on 136kHz QRSS. I used the E-field probe for 136kHz on a mag-mount on...

Some time ago, I was asked by email if the technique to make this into a full TX-RX transverter as used on 472kHz could be adapted on 136kHz...

It is many years ago since I last transmitted on 136kHz. A record of my experiments is on my old website. The links are unreliable as this ...

In the coming LF and MF DX season, I hope to be on RX with an E-field probe antenna. As this has to go in a tree, this depends on getting so...

Although I tried 136kHz OPERA RX last winter, I have never, yet, transmitted on this band from this QTH. Somewhere, goodness knows where, I ...

At about 1920z I QSYed to 136kHz RX from 50.280MHz (6m) MSK144 RX.  As yet, no spots.

There is no doubt that I have to improve my RX system on LF and MF. Last night I spotted the same few stations on 136kHz WSPR and OPERA, g...

For about 45 minutes now I have been on 136kHz WSPR RX and 136kHz OPERA RX. G4FTC (123km) has just started to be spotted on WSPR. I have to...

Yesterday evening I was on 136kHz RX again. On WSPR RX  2E0ILY, G4FTC and G8HUH (250km) were spotted. On OPERA RX the only station spotted w...

About an hour ago, I QSYed to 136kHz RX. Both WSPR and OPERA are being monitored. As yet, no spots on WSPR. I need to look on a different PC...

As is my norm, I QSYed from 6m (sometimes 10m) to LF (sometimes MF). The shack PC was on battery power to keep the SMPSU noise to a minimum....

Rather early, I have QSYed to 136kHz WSPR RX and 136kHz OPERA RX. I hope I catch some stations this evening. UPDATE 2055z:  G3XIZ, 2E0ILY ...

In the end I just remained on until the shack PC's battery went flat. This was just after 0300z. The batteries last a long time!  On W...

At the moment I am monitoring 136kHz WSPR RX and OPERA RX. As yet, nothing copied. UPDATE 2006z: G3XIZ copied on 136kHz WSPR.

Yesterday evening and overnight I was on 136kHz WSPR RX with a preamp in circuit. Only 2 stations were spotted - G3XIZ (46km) and G8HUH (...
