Well, that was a non-happening!  One of my plans for now was an E-field probe in a tree for 137kHz and 472kHz RX. We had the tree lopped, bu...

Hopefully, my transverter works. I shall try later. Whatever happens, I intend to be on 472kHz (630m) this evening. If the transverter work...

Looking back over 2018 I see I failed in at least one project aim!  I actually bought the e-field probe, but it has still to be erected. May...

A week ago a unique LF test took place in Germany by Marcus, DF6NM . This morning I attempted to transmit from a small ferr...

This winter, I went on 137kHz WSPR RX for the first time at this QTH. I used my earth-electrode antenna in the ground. Really, I ought to ...

For the last few nights I have given this band a miss. I seem to spot the same stations again and again. Someone pointed me towards 2m FT8 a...

As 10m and 6m were quiet, I have QSYed to 136kHz RX on WSPR and OPERA.

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 ...

Last night I did not go on LF or MF as my shack PC was playing up. I intend to go on 136kHz WSPR RX and 136kHz OPERA RX tonight. I  need my...

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 (...

Thanks to the great kindness of an individual who shall remain nameless, I am looking on 136kHz WSPR with better sensitivity. This amateur ...

A couple of Gs came on. G3XIZ (46km) was 2-3dB better S/N on the earth-electrodes than on the compromise vertical. He is end-on to the &quo...
