Thank you for the info Roelof and Stefan
We will wait and see if they pay the bill or not ;-)
>>What have you done on VLF? What have the steps been? :-)
Not much. Added a GPS which will be used to discipline the soundcard
And still using MiniWhip and Perseus. I was using an isolator transformer at
SDR input
to cut RF currents reaching the antenna but looses were too high at VLF
Now I'm running without transformer and can see JXN strong at 16400Hz
along with lots of birdies and local noise

There is also a trace at about 14.880952 kHz but really don't know if this is
the
Russian Alpha or just another birdie
Next step is a dedicated VLF antenna direct to soundcard
>Did you see, i've been on MF WSPR last Saturday ;-)
Sure ! We were the only ones getting TA spots last saturday night
Wellcome back to MF :-)
