Hi Eddie,

Also thanks for watching! Where can i see the trace? A link or a screenshot?

Yes the plan is to wind smaller stacks that allow various combinations and resonance frequencies. Also i thought about cutting the tube in the center and to insert a blank piece of tube, so the stacks can have a selectable spacing. This would be an advantage because letting a stack out of the stacked stacks ( :-) ) also reduces the overall voltage capability.
Yesterday i removed the faulty stack, the first step of the repair process. The fault was quite in the center BTW. This can be expected because the flux is highest in the center of the coil and so the voltage per turn or per layer. It took me 2.5 hours to carefully remove the wire. I will use it again for the new improved stack(s).

Hi Stefan

Nice to see some signal again < 9kHz, it makes the electricity bill worthwhile.

Your signal 10dB above the noise peaks in 47uHz here. Also a nice line in 424uHz as usual.

I did wonder if with a part of the 2kHz coil defunct and under rewind maybe the resonance was going to be around 5kHz, pre warnings please for any frequencies that may appear and are not currently being grabbed.

Hi all,

Just in case someone new or old wants to try, i'm running 700 mA again on 8270.005 Hz until 05:30 UTC.
It is a first test for a new RX stn on VLF! If the trace will become visible, it would be a new personal distance record < 9 kHz for me :-)

It is still to early to hope much, no GPS module is available so far.

But i can tell you i have been in contact wil RC4HAA (club station) in LO53CF! See their grabber (running on VLF since a few days) at
A GPS module with PPS+NMEA will be available in a few days...
