It is probably easier on LF than MF. Aim for around 1W erp RF
Simplicity is the answer

Hello Luis, LF,

I am afraid I have to agree with Chris here. I am in awe and have
great respect for Paul and those doing amazing things at VLF, but
EbNaut is not for the rest of us until someone writes more
documentation that fills some major gaps.

I have read the pages on EbNaut many times in the past months but I
cannot even start to get my head around what I would need for
hardware, let alone the software configuration. My best guess, since
I can't get any sense of the hardware required, is that it very
likely is beyond my budget for some years. As for what is written,
most is for VLF where (I guess) equipment is very different? This
creates even more difficulty for those like myself who might want to
try it at LF.

A great place to start if someone were to write articles for the
rest of us would be about the hardware requirements. Is there more
than one way to do it? What is needed? How do you build it?

73,
Paul N1BUG

Hello Luis,


My take on Ebnaut is it's undoubtedly a superb medium for low signal
level transmission and reception, but until someone makes it available
as single package that installs itself like WSJT-X or OPERA it will
remain a very niche piece of software used pretty much solely by
"geeks" who enjoy the challenge of grappling with getting it all
working. I hope this doesn't sound offensive to others, I am just
telling it as it is from my point of view. I'd love to try it but not
being particularly computer savvy, and having battled Linux on several
occasions and given up with its obtuse structure and commands, I will
probably have to sit back in awe of those who have mastered it and got
the amazing results Ebnaut has shown itself capable of.

Kudos to Paul, and those utilising his tools on LF and VLF I'd love to
know something of his background and job, should he wish to share,
he's obviously an immensely talented and driven gentleman!

Hi Domenico, LF



I agree with you that EbNaut is the way to go for DX in LF. And

QSOs can be made using short symbol durations at least equal to a long QRSS mode

Would be interesting if you recall the modes and time windows
involved in that QSOs that took place in LF



But (at least muy experience, for a dummy and NON Lynux user) the

different software packages needed and the lack of clear descriptions on how to

setup all the switches is a BIG problem and scares most OMs. The

reward is to gain a LOT of dBs using the same station setup. So it really worths the effort

Of course, i'm also at disposal to put on air a small EbNaut signal on LF from my locator JN80nu

Please do it. Would be very important to get your EbNaut

transmissions in LF as a reference. Specially to check if one can do it with an stable receiver

but not GPSDO disciplined. This last step is complicated for many

receivers and not easy for many OMs. I’m using Perseus SDR which needs a GPSDO at

88MHz, but the existing TCXO looks very stable and think would work
just determining the QRG shift and compensating for  that

I believe that using EbNaut on LF (i.e. dealing with more robust signals than VLF) can be a very good training for acquiring the skill necessary to use EbNaut on VLF.

Absolutely agree ! J
