Hi LF

Thank you for the reports, Domenico, Graham

I have seen also Deep Search decodes at Stefan LF DX Grabber

2016-04-14 05:32:51 EA5DOM  1398km 137512.003Hz   3mHz -45.9dBOp  99% 17.8dB

Last night EB3FRN best decodes were at -30dB

23:33    136 EA5DOM de EB3FRN Op32 297 km -30 dB F:0% in Montbrio 1512,0 Hz
23:33    136 EA5DOM de EA5DOM Op32 0 km -8 dB F:1% in Albir 1510,4 Hz
23:01    136 EA5DOM de EB3FRN Op32 297 km -30 dB F:0% in Montbrio 1512,0 Hz

Yesterday I increased lenght of the top load sloppers from 6 to 11m each. That let me to remove the

last minute coil winds and seems like it is working much better with added top load capacity :-)

Looks very promising. Let's see what happen when using an small PA

Will keep it running during daylight also

hi LF,

OP32 signal from EA5DOM was picked up during the night also from my opds grabber in JN80 (1500 km)

https://www.dropbox.com/s/3l8la03yrpqdo0j/DETECTED.TXT?dl=0

Many compliments to Luis for his antenna arrangements that it is performing very well also in LF.

GL for DX!

Hi LF

First test with 100mW from U3

Iban EB3FRN decoded it in Opera Dynamic at sunrise

05:02    136 EA5DOM de EB3FRN Op32 Deep Search 297 km -42 dB in Montbrio 1499,9 Hz

Still a lot of room for improvements, but looks like the antenna performance is as good as MF

Hi Stefan

 

Yet another convincing argument:

 

As isolated coil, it can be covered with a bigger buck to get a step into VLF  ;-)

Hi Luis,

I prefer to set it appart. It is a truncated cone, so would have a natural tendence to "unwind" just by gravity

In the hot summer I would surely find the cable messed down at the base of the pipe :-)

That's a real argument!
