Hi Dave,
for first tests I use antenna mini-whip with 1m long rod and Degen
DE1103 for band 40-150kHz.
For other tests I use also modificated miniwhip, but direct to
audiocard (48kHz) and software Spectrum lab or Spectran.
You can see it in "Files" "1.zip" where is also schedule of VLV
stations compiled by other schedules (I dont know, if it has good
data).
You can see many signals, but I cannot identificate many signals too.
You can see for instance signal at 10kHz but Omega system is OFF?
Can you help me with identification my "unids"?

Regards, Jara Rat
