Hi Dani,
Thank you for commenting my proposal content though my question is somebody will
guide me to the procedure to add new feature to WSJT-X specification and
implementation new feature".
However, I will try to explain the questions raised from you here if I am
allowed.
Q1. Is it some sort of online server to exchange the information about what
frequencies people are using?
A1. Broadly, answer is "yes" but strictly, "no". Proposal is to closely work together
among WSJT-Xs and on line server as "network layer".
Q2. A better solution to the problem you mention about incompatible band plans
is to listen simultaneously on different frequencies so that split random QSOs
can happen without the need for external coordination about the frequencies.
This can be done with adequate hardware (SDR). In the
HF bands it is easy to accomplish this.
A2. Yes, you can achieve by your proposal. However, 100% HF radios in the
market today is 3kHz narrow band ones even it is SDR architecture. The
intention of my proposal is to achieve the purpose with the addition of network
layer. I agree with you that it is easily possible to accomplish at HF from
technical viewpoint but I do not believe entire market will be driven as you
expect.
Q3. I understand that this problem also happens in 13cm EME, where different
countries have really different allocations. Here it is more difficult to
listen on all the possible frequencies (the separation is several MHz), so
people coordinate frequencies using HB9Q chat or other sked
online services.
A3. Thank you. my proposal can address 13cm EME band as well. I will include
EME situation in my updated proposal.
Q4. Finally, I think it's important to try to harmonize working frequencies on
a global basis. This simplifies things a great deal. Sometimes it is not
possible to achieve a completely global solution due to different band plans,
but imagine the mess if every country used a different working frequency.
A4. I have the opposite view about the topic. It is the right time to consider to abolish
the harmonization efforts even at HF which has been classic radio problem unsolved for a
century. There are multiple solutions including yours today. Let's eliminate
"working frequencies" from WSJT-X specification. This is the intention of my
proposal.
Again, I am happy if some member will guide me to the proper way be able to
discuss about the contents of my proposal in this society.
Regards,
take

Hi,
I am a newbie of this mailing list and I do not know the details of the
procedure to add new feature to WSJT-X specification and implement new
feature.
However, I have a proposal of these and it is attached to this mail.
I am happy if somebody guides me to participate the process defined in
this society.
I am waiting the reply soon.
Hi Takehiko,
I've read your notes and I don't understand well what this Frequency
Management Center is. Is it some sort of online server to exchange the
information about what frequencies people are using?
I think that would belong more to an online chat server or some other
service where people can set up skeds rather than WSJT-X. I think that
it's important that QSOs with WSJT-X can be done without exchanging any
data through the internet, so people can choose if they want to
coordinate QSOs with the help of the internet or not.
A better solution to the problem you mention about incompatible band
plans is to listen simultaneously on different frequencies so that split
random QSOs can happen without the need for external coordination about
the frequencies. This can be done with adequate hardware (SDR). In the
HF bands it is easy to accomplish this.
I understand that this problem also happens in 13cm EME, where different
countries have really different allocations. Here it is more difficult
to listen on all the possible frequencies (the separation is several
MHz), so people coordinate frequencies using HB9Q chat or other sked
online services.
It would be nice to allow for the possibility of indicating in the CQ
call which other frequencies you're listening to. The problem is that
this is potentially too much data to include in the short messages that
the JT modes use. The only similar feature is the "CQ nnn" feature,
where you can indicate another frequency where you're listening and
where people are supposed to call you.
Finally, I think it's important to try to harmonize working frequencies
on a global basis. This simplifies things a great deal. Sometimes it is
not possible to achieve a completely global solution due to different
band plans, but imagine the mess if every country used a different
working frequency.
73,
Dani.
