No decodes from Dave last night but a few GMs on 475kHz WSPering at upto 800km .

I am a newcomer to LF , having been NDB banging for some years the recent beta releases on WSJT-X have made things interesting for the older people on the band .Some of these stations were built up to work DX using Marconi T antennas and several hundred W of PA output .100Ft tall masts and inverted Ls are in use .

Amazingly I manage to hang on to a few shirt tails using an E Probe antenna for RX , in a Pine Tree @ 5m agl above "rubbish" ground .
The probe + either my SDR-IQ or ELAD FDM Duo are good from 10kHz to  10MHz .

For a pcb and components at around £10 the probe is beyond compare for low noise floor performance in terms of £/km .

I could never much hear 160m traffic on a 1/4 wave sloper but with that as a TX antenna and the E-probe on RX several thousand km are available at times .

No signs of LEX on 10GHz or CAM , so wrong kind of Snow from here .....

I chat with GM3YXM on 160m every morning (another LF regular),  normally he is a couple of dB above the noise, today a good S9 +20 ... another regular in Portsmouth gave hime a similar report, everyone was up at least 20dB, quite remarkable.

Hi Robin,
Blue Sky and Sunshine now - Topband (1.8MHz) is normal level here but on the real "Topbands " at 137kHz and 475kHz it was quite lively overnight .
Plenty of TA  WSPR-2 and FST4W modes .

WSPRSpot site says I decoded 20 spots on 137kHz ( poor by recent times, but it was crunchy at times from lightening out of Snow clouds etc ) and 1038 spots on 475kHz .

Several G stations have had 2 way QSOs with the States and JA on 475kHz

Quite a few uwavers are active on LF/MF .....

At the other end of the spectrum, top band is unbelievably good at the moment .. never heard anything like it.

A large band of snow cloud heading East from this QTH is producing SS from SEE and PKT .
