1164Re: Active antenna connection to soundcard input
- Jan 1, 2013Hello Alan
I have just started to work with spectrumlab.
I have this antenna for other HAM purposed and was planning to
start with this.
As Final purpose I have planned to monitor Solar SID monitoring VLF stations.
May for this wire loop antenna is best. (My findings from google) ?
