I misunderstood, when you were talking about VHF/UHF I read that as if 
you were suggesting that 1 baud was being given only a 20M frequency.

Re: [digitalradio] Spectrum is for ALL users

Technically, that is true. However, the problem I see over here is many 
times ROS decoding is stopped because of interference by other modes 
(Olivia and Pactor both), and not so many times as ROS interfering to 
other modes. Yes,  that has been complained about also, and I have 
sometimes also seen ROS 16 stopping Olivia 32-1000 decoding.


Perhaps others will offer an opinion.

I dont create ROS 1 baud only for EME operation. ROS 1 baud is also for QRP 
enthusiasts in HF. I think these people have the same right to experiment with 
weak signals in HF, and we should select some channel for this propose.  

But obviusly, should have more channels to 16 bauds than 1 baud.

Sorry Dave, I don't follow you as to what would be "stupid".

The point is that any suggested frequency exclusive to 1 baud suggests to 16 
baud users to stay off. However, there are many more 16 baud users than 1 baud 
if you monitor both frequencies, and QSO's move much faster, allowing for more 
users to use the space. Suggesting 1 baud primarily for VHF/UHF, where it is 
more effective, would provide more suggested space for 16 baud users on HF and 
relieve congestion.

20m is only one example, of course, and the same principle could be applied to 
other bands. 

Perhaps I misunderstood you.

I agree that is easier. The problem is that 14109 has been designated as 
1 baud exclusive, so that is not suggested as available to go to. Even 
though is an advantage to being about to work at -35 dB S/N, the 
advantage is much greater at VHF and UHF, where atmospheric noise is a 
greater problem than on HF. So, if 14109 is not suggested as exclusive 
to 1 baud, there will be more space for HF users of ROS to go to avoid 
QRM or ROS interference - practically, on 20m, twice as much space.

Steinar, that is absolutely true, the spectrum belongs to everybody, 
but the other side of the coin is that we need to "police" ourselves, 
and that usually means moving around to better accomodate other users 
of the spectrum, or by their moving also. This is how we arrive at 
bandplan divisions of the legal spectrum allocations.


I have been monitoring ROS all day, and in this country, Olivia 
stations cause as much trouble to ROS as ROS causes to Olivia. It all 
depends upon the relative signal strengths as to which one decodes. I 
see many ROS QSO's stopped by Olivia 32-1000 traffic on 14106.


Since the 1 baud mode is slow and probably going to be most useful on 
VHF and UHF for weak signal DX or EME where S/N is a much greater 
problem than it is on HF, it might be better to suggest moving the 
recommended ROS 16 baud 20m frequency to 14109 to avoid collisions 
with Olivia, and avoid Olivia interference with ROS, and mainly use 
the 1 baud mode for VHF/UHF weak signal work where it is needed the 
most. Right now, an automatic Pactor station is also disrupting ROS on 
14106.

That has always been true Jose.

Unfortunately, some people think that they either have 'the right of 
might' or 'previous occupancy' rights on a frequency.

The right of might involves using high power and big antennas and, I 
think, comes from SSB and CW on the 'DX' bands.

(Here I speak as an enthusiast for CW as well as data modes, but not for 
imposing your own will in either case)

Previous occupancy now seems to come from various other modes.  As if 
"we were here first" was an argument for excluding other people who have 
the same rights to use the bands that they have.

'They' might say that 'We' are interfering with them, but equally 'We' 
might say that 'They' are interfering with us.  After all, no one owns 
the bands.

I think this is a lot easier. If you see a channel is occupied by Olivia, go to 
another channel. And if you see that a channel is occuped by ROS and want to 
transmit with OLIVIA, do the same. 

What i cannot say is "The 20-meters band is only mine".

Steinar, that is absolutely true, the spectrum belongs to everybody, but the 
other side of the coin is that we need to "police" ourselves, and that usually 
means moving around to better accomodate other users of the spectrum, or by 
their moving also. This is how we arrive at bandplan divisions of the legal 
spectrum allocations.

I have been monitoring ROS all day, and in this country, Olivia stations cause 
as much trouble to ROS as ROS causes to Olivia. It all depends upon the 
relative signal strengths as to which one decodes. I see many ROS QSO's stopped 
by Olivia 32-1000 traffic on 14106.

Since the 1 baud mode is slow and probably going to be most useful on VHF and 
UHF for weak signal DX or EME where S/N is a much greater problem than it is on 
HF, it might be better to suggest moving the recommended ROS 16 baud 20m 
frequency to 14109 to avoid collisions with Olivia, and avoid Olivia 
interference with ROS, and mainly use the 1 baud mode for VHF/UHF weak signal 
work where it is needed the most. Right now, an automatic Pactor station is 
also disrupting ROS on 14106.

Hi,


>From 14101 to 14112 is the range legal in the IARU Regions for DIGIMODES until 
>2700Hz.

You cannot use all the spectrum exclusive for you because spectrum is for all 
hamradio.

OLIVIA and ROS have to share frequencies, as well as future modes that will 
emerge over the coming years. 

About that Olivia is the only mode that allows errorfree signal transfer at 
worse conditions,I think you're quite wrong.

 Best regards, Jose Alberto
