At the moment, I am using the Wellbrook LF version (down to 10 kHz). As the Octo has a 96 kHz sample rate, I would like broad-band loops to make full use of its range up to 48 kHz - but probably too ambitious. For sure, I would like to have the capability to participate in your EbNaut tests at 8270 kHz and lower. It looks like I'll have to hurry up and get things built, otherwise I'll be too late as you will have done everything and moved on to a completely different challenge! Learning how to drive Paul's vlfrx software (and Linux) is also a challenge for me, even with Paul's helpful tutorials. A longer term plan is to use the Octo/RaPi system as an if stage for some sort of multi-channel coherent receiver system for lf - hf monitoring. 73 Terry On 20/06/2017 15:40, DK7FC wrote: > Hi Terry, > > When you managed to build up your system, what do you intend to do > with it then?
