I have been reading the discussion about what is possible and impossible
with the ARM evaluation board. The proposed idea(s) to build a versatile
receiver which could be used for receiving various time/frequency
reference transmitter around the world sounds great!
It is my believe that the time-nuts group is strong, professional and
inventive enough to "produce" such a system. I think it will allow a lot
of people to do experiments with (V)LF reception of time/frequency
signals in a professional way.
The HPSDR project (www.HPSDR.org; which is known by a number of people
here) has proven that it is possible for an internet community to
produce real hardware! I'm willing to provide my help and knowledge if
and where possible. Allthough, I have to admit, I'm at this moment
rather busy with the HPSDR project (the power supply part called Demeter).
Maybe we could even make a collaboartion with the HPSDR project. There
are advantages for both communities:
* The HPSDR is still looking for a suitable frequency reference for
their system, allthough a start has been made for a GPS-reference system
* The Time-nuts list could benefit from the knowledge the HPSDR
community already has about production of boards and SDR
Furthermore, both communities are collaborating with TAPR!
The way HPSDR works is as follows: A project leader is "choosen"
(usually the person who volunteers) he makes a proposal for the project.
All the others are invited to share their comments. This will lead to a
program of requirements.
Now the real fun starts, the design of the system, while the design is
growing all people can contribute their knowledge, experience and even
some hands-on work. This wil yield a system which should be near to
I hope we can start a similar (but probably smaller) project like
HPSDR. I think it is a great opportunity. The idea is very interesting,
it is difficult for us to compete with the big manufacturers of
GPS-based references. But in the field of (V)LF frequency and
time-standards there is a lot off room for us, to play and experiment!
Question is, are we willing to do that? I would say, let's do it together!
I'm very curious about your reaction/opinion!
