Re: [digitalradio] Re: HRD with Microham

2009-10-27 Thread Pat Turner
Andy and the group, what do you use for call sign lookup? I am a paid 
subscriber to Buckmaster HamCall, it works well with the mixW, but looks like 
this doesnt work well with HRD.. Several posts on this, and some in a To-Do 
list on the HRD site.
I printed the manuals (where i work-many pages) and have been reading and 
getting ready for the changeover (if i do it)
thanks

Pat, I use a Microham device with a TS2000 and run HRD, FLdigi, Multipsk or 
MixW without any issues. You can essentially leave your Microham device router 
as selecting the same ports for PTT and control and all should be OK.

HRD with DM780 can be a little overwhelming these days because it has so much, 
and so many visual options. However, all you need to do is configure HRD for 
your rig and rig's baud rate , plus the comm port you use for rig control. Then 
in DM780 configure how you want to set-up PTT. I always find this confusing in 
many different applications but in HRD there are only 3 options (I think) , so 
it does not take long to try all three if needed. HRD and DM780 also have an 
effective method for linking the two, but you have to set this up. It is all 
explained in the help files but I always find it confusing.

 That is a difficult choice Pat. I am an old Mixw user too, paid my many to 
 Nick many years ago. 
 
 My sense, no facts, is that Mixw is a dying product. It is a good product but 
 I just have a hunch that Nick has tired of the project and that it is not 
 likely to get the updates frequently enough to compete with DM780, fldigi, 
 pocketdigi, or Multipsk.
 
 You can run MixW with FLdigi (other other apps with RS ID) in the background 
 and use RSID receive just as a way to keep any eye on what is on the band .

Re: [digitalradio] Why would anyone

2009-10-27 Thread Charles Brabham
Hard to tell if you are trying to ask a question, or make a statement. In 
either case though, your post indicates a lack of understanding that I may be 
able to relieve.

Unattended operation has been codified into PART97 for close to thirty years 
now, and was done in response to the emergence of digital communications on the 
ham bands. Part of the 'why' of this codification of unattended digital 
communications can be garnered from the introduction at HamRadioNet:

=
Amateurs radio operators are the only group of private individuals in the world 
who have the ways and means to fund, build and maintain a worldwide 
communications network, independent of the internet and commercial or 
government entities. This is our own mount Everest, that only we may climb 
'because it is there' only for ham radio operators like ourselves. 

We do not have to worry about how our efforts compare to others in this area, 
as there are no others who can reasonably attempt to approach this task. 
Whatever we accomplish here is the state of the art, and represents the 
combined, cooperative efforts of thousands of individual amateur radio 
operators around the globe. 

To be involved in the global amateur radio network is to be a part of amateur 
radio's single greatest international accomplishment, and the true advancement 
of the radio art. 

=

The original Packet network that the new sections of PART97 and the automated 
sub-bands fostered is still functioning well after close the three decades, 
though it has suffered a setback due to the advent of internet communications. 
This setback is not due to 'competition' as many erringly express it, as the 
internet is not an amateur radio activity at all, which precludes any 
'competition' between the two. Remember that amateurs are prohibited from 
providing any communication service in competition with existing communications 
services in any case, as we have recently been reminded by the FCC.

The internet-related setback that the Packet net experienced was partly a 
brain-drain as digital networking enthusiasts moved on to internet services 
where they could get paid for their work, partly due to over-hyping by the ARRL 
that turned into a distinct liability in the face of near universal internet 
access, and partly due to the realities of networking with amateur radio, which 
cannot really adhere to the internet model since our long-haul 'backbone' links 
( HF ) are significantly SLOWER than our access links ( VHF,UHF,SHF ) directly 
opposite to the model that wired networks like the internet are built upon.

That last factor, the way that the relationship between the throughput of 
'backbone' and 'access' links is reversed from that of existing wired networks 
has turned out to be the biggest setback of all, as many amateurs just do not 
appear to be able to comprehend digital networking on any basis that is not 
identical to the internet ( wired ) model. Because of this, various unfortunate 
attempts have been made to make digital ham radio networking fit the 
procrustian bed of IT. ( internet technology )

We see that in the unrealistic and obnoxious attempts to obtain high-speed on 
HF, which always involve ultra-wide digital signals which have no place in 
limited, busy, shared HF spectrum. We see it in the attempts to provide 
'privacy' in ham radio pectrum, where we are expected to self-police through 
the process of peer review, and we also see it in the cases where amateur radio 
digital networkers throw up their hands and use non-ham communications 
resources ( internet gateways ) to route around and exclude amateur radio 
digital links which do not fit well in the only networking paradigm they 
comprehend. - It is ironic but true that these confused individuals actually 
think that they are making digital amateur radio 'better' by taking te radio 
out of it, substituting non-ham resources in its place.

By the late 1980's, amateur radio operators had developed a digital network 
that spanned the globe, involving the efforts of thousands of amateurs who 
worked to build network resources on all of the commonly utilized ham bands. 
Besides the world-spanning HF network, there were large-scale VHF/UHF 
terrestrial networks that covered large sections of the USA, most of Europe and 
metropolitan areas of many countries around the globe. 

Some of that has gone away in response to widespread internet access, no more 
ARRL hype, abortive attempts to repeal the laws of physics, and the inclusion 
of non-ham links which only served to retard the advancement of the art instead 
of bringing it forward. Still, a large part of what once was is still in 
operation, though at a reduced level of traffic and coverage.

The good news is that we are now approaching a turning of the tide as amateurs 
once again approach the concept of a global amateur radio digital network with 
a new understanding of the pitfalls we face, along with the advantages we enjoy 
over

I have to admit to sympathizing with those on this list who express

they exceed baud rates and bandwidth limitations in the USA.  Obviously, if

Or, to take it to its [il]logical extreme, make the maximum bandwidth 31 Hz. 
and outlaw everything except PSK31.  Maybe JT2 would be even better...

That rule would need as much interpretation as the one about power.  You 
could communicate worldwide on a couple of watts *IF* you picked the proper 
mode and were willing to wait a few years for the right number of sunspots. 
The hardest word to define in law is the word reasonable.
