[digitalradio] Measure background noise

[Toby Burnett]

Hi all, 

Just had my arcing power line pole fixed and my noise has dropped off to
zero on all HF bands except 160m, fantastic!!!  And a result. 

A friend of mine said that his noise floor was -110db.  Impressive I think. 


All I know from my spectrum scope is that mine has dropped by about 40db+ 
but I am curious how you adjust your card input level so you can get a true
db reading for the ambient noise floor.  I.e. How did my friend arrive at
this figure. 

I have a sound card oscilloscope and a copy of spectrum lab (which is where
I compared the before and after results)

Could someone explain please.

Regards

Toby MM0TOB<>

Re: [digitalradio] Re: Statement on Withdrawal of Support for ROS (K3UK Sked Pages)

[Toby Burnett]

Ok hang on
 I just read the statement.  Doesn't it say that use of spread spectrum is
not permitted below such and such a band.  However I see reasonably no
different a spread spectrum exists to the USB /lsb/ 20m packet, amtor/
pactor etc etc i.e. 2.4khz or less  (and AM is that very wide ) that
would challenge that.I know I have been active within this group but
cant see the problem. 
As long as it is within the usual pass band of ssb what's the problem.  If
what they are saying is true the armatures wouldn't be allowed ssb /  am .
Communications surely. Unless we used some magic tuning to over th band for
one qso?

Again I am not the most technically minded but wsy.  

I may be stepping out of line but   although I think the discussion has gone
long enough.  I don't see why operators should try another mode.  Is this
not in keeping with the spirit of ham radio after all. \this is an
experimental mode and worthy of discussion I agree.  

For example.  I have a sparking power line which the UK Scottish power will
do nothing about. How about having a go at the commercial companies for
ruining our hobby rather than us all squabbling over something  so trivial. 
 

As I said before 

C 24 is on us and I am hoping to receive a 746 Mk 1 and generally am happy
to work new dx, speak to locals and usual suspects and generally have a good
time. 
I'd be so much happier if the power company fixed my power line. As s8 on
20m


Enough said

Well, I was going to start using ROS on UHF and maybe occasionally on HF and
let the K3UK decision and other chips fall where they might.

However, the ARRL just released a statement indicating that the author of
the software has lied to the amateur community about the legal status of his
program in the USA. 

Read this if you care:

http://www.arrl.org/news/stories/2010/03/04/11377/?nc=1

In view of the foregoing, I will not use ROS in my station. Nor will I
recommend that any other ham use it. I will stop short of suggesting that
anyone NOT use it (at least on UHF where it is legal here in the USA).

Re: [digitalradio] Re: ROS operating frequencies on 20m

[Toby Burnett]

OMG I'm not that technically minded  but isn't there a compromise? 
I seem to be going from one side to the other I know, but
Cant everyone use ROS at a specific place without disturbing the beacon
network  and olivia.  After all we have sstv way within the 20m band at 14
230   surely if this had been a NEW mode in 2009 / 10 no one would have ever
thought of that frequency.  It is just tradition.
As it is such a wide mode then what if everyone makes it just above or below
the sstv frequency ?   Just a thought I had and it is late hi hi . 
Surely regardless of the mode used it could be up to our own decision where
one wants to use this mode ?  Certainly right next to the beacon network is
a bad idea.  Hence if I think right the olivia channels have been designated
from about 14.105mhz up   to 109 if I am right. 
Isn't the spirit of amateur radio to compromise?  
I know I keep putting my tuppence worth into this discussion but it makes me
mad as a relatively new ham operator circa 2004 
Once upon a time I was quite happy with psk/rtty/mfsk and mt63 but times
have a changed. I wonder how all these modes got their own frequencies
in the first place and why not ROS the same.  ? ? ? 

AS for the threats, well I am kinda with you on that one.  Not in the spirit
of ham radio.  But...This is like a child's playground all
wishing to comment if the slide is to fast / high lol

OK, I understand. That still doesn't make it impossible to use somewhere
above 14.109 though, does it?

Well I guess now it's immaterial to you guys anyway. What I don't understand
is why anyone still wants to use the mode. The developer has made threats to
other amateurs, he has posted false information on his website and risked
bringing the hobby into disrepute. Anyone who continues to use it is
basically saying none of that matters.

Re: [digitalradio] Re: Statement on Withdrawal of Support for ROS (K3UK Sked Pages)

[Toby Burnett]

Marc, 
I'm not saying that,  I'd be happy to support ROS and I do think it's a
rather good experimental mode.  Ok so it is wide but as I said "experimental

I think Jose did a fantastic job of making a software package for a
completely new type of ham radio mode.  BUT, 

The debate is getting out of hand (period)
There are reports of much QRM with the mode as no one seems to know where to
operate.  Or they just don't give a damn where they operate.
Have you checked your messages?   How many on this subject since the
software came out a few weeks ago. 1000+?
Is there nothing else we can talk about. 
People are worried about their operating privileges in certain countries.
And why not if there is a problem. 

There shouldn't be and I don't think there are real ROS haters, just those
who probably want nothing more to do with it, this discussion and I can see
some people un subscribing from the group or sticking it to the junk filter
 

In keeping with ham radio, I think everyone should calm down a bit and maybe
do a bit of operating now that cycle 24 is in progress, rather than worrying
about this.  

Oh and I just had a listen and I cant hear the beacons due to ROS and a
packet station.  14.101 is just too close I think.  
Listen on 14.100 and you will hear.

It seemed an interesting experimental mode, I agree.  But to be honest I don
t think I shall bother too now as there seems much to much grief happening
from this.  
Like I say, it seemed a fair experimental mode but it is wider than most and
their isn't much room on the bands anyway. 
Shall probably stick to CW, PSK, RTTY, JT65, OLIVIA and a few others.  

It'd be nice to see something other than ROS comments on the digi reflector

Re: [digitalradio] Re: Consensus? Is ROS Legal in US?`

[Toby Burnett]

For the love of god,  (just an expression) 
Will everyone please stop !!
 
Over night I have received over 80 messages regarding this conflict.  It is
beyond a joke surely. 
 
I must admit that I haven't  even read all the messages, but come on folks. 
 This is getting out of hand. 
ROS seems to be no more than using a single frequency with a multi hop FSK
signal that takes up an enormous band width. 
Ok so it is large but so are other modes such as mt63 or olivia 2000htz 
what is the problem. ?
Use it where the band plans allow I.e. In the voice spectrum.  Stop all this
crap about it has to be in with other digi modes (does anyone have a problem
with sstv in 14.230 as it is no where near the other digi modes.)
It is not a spread spectrum frequency hopping mode, indeed it only transmits
in the pass band that your radio is on, not frequency hopping as the FCC
mentions.
Give us all a break, please. 
 
If you don't want to use it, then fine. 
If you do, then fine. 
 
I'm sick and tired of opening my e-mail and seeing the same spiel as
yesterday and the day before and the bloody week before that. 
 
Put it like this, if it is so bad and you call it spread spectrum frequency
hopping mode. Then what is ALE and the like?  Does it even look to see if
the frequency is in use when it changes band automatically.  I think not. 
Do the pactor stations give a damn when they blast my signal when working
olivia, rtty, ROS, etc .   NO
 
Give it up people
I remember starting in ham radio due to it's unusual regard for self
bettering, understanding and experimenting. 
  Not bureaucracy and the like. 
 
My 2p worth.  I have had enough.Maybe Jose shouldn't have called it SSFH

In order for amateurs in the U.S. to use any RTTY/data mode other than

OK, I am starting to agree with Dave now  and with Andy as before ...
this is starting to now become circular .

It has now been solidly established that ROS is FSK, NOT SS, by the authors
own words.

The author NEVER approached the FCC for an "OPINION" about his "unfinished"
work at all. Indeed he made it clear the whole thing was still "BETA" 

In the US, when has an "OPINION" of someone lower than the enforcing
authority made anything legal or illegal? It was only an opinion of one of
the agents (agent #3820) based on the incomplete data provided to them. had
I been that agent, I would have said the same thing under the circumstances
of only having incomplete, inaccurate documentation presented to me.

Jose, the author, has already indicated he intends to correct the error in
his updated documentation which should remove all questions about legality
in the US. It is not necessary for him to provide anyone with his algorithm
so long as he continues to provide his program so that anyone can monitor
the transmissions. The transmissions all fall within FCC guidelines already,
that has never been argued. The only real argument has been, is it SS or FSK
 If it is FSK, it is NOT illegal. The spread spectrum rule simply does not
apply here.

What more will the outcome of this discussion ultimately determine?

Presently, the FCC is so understaffed due to budgetary constraints, my guess
is that they really do not have the resources needed to chase such
questionable things as this in the first place. Can anyone imagine our
enforcement group is going to expend the kind of resources necessary to
enforce something that is likely not really an issue in the first place?
They are not there just sitting and waiting to jump on anyone "potentially"
violating such a questionable matter in the first place.

As for the requirements of how this software generates or does not generate
it's spectrum should no longer even be a question since the only reason it
was ever argued in the first place was based on the authors misunderstanding
of OUR (the US) definition of SS versus FSK. Once he (the program author)
understood the difference in that definition, he immediately noted his
program was NOT SS at all, but was in fact FSK. Argument should be over?
TRUE? NOT TRUE?

Dave, where would we go from here . if we were in your country?

Re: [digitalradio] Re: Considerate Operation: CW and JT65A

I agree with that, and I see modern day rigs have a tremendous amount of
filtering capability.  I'm talking about the likes of the 756 pros  / FT1000
s / ts2000's etc etc and other such radios that would take a small mortgage
for me.  I notice that these have variable band pass filters and the like
that could probably narrow the pass band to a few 10's of hertz  enough for
a single cw or bpsk31 signal.  I suspect that these work on TX also ? Like
me and many many others who run older equipment without all the bells and
whistles though, as you say.  I was always taught to listen first and then
listen again.  Although just remember that we don't all have the super dsp
and notch filters on our radio's.
Out of interest,  do common filters work on TX or just rx, and if not   
why??

I often "look" at the CW signal on the waterfall when I hear one close to me
  My view is...if his signal is not exactly on the same part of the
waterfall as mine, we are "OK".  I can notch him out and he can do the same
to me.  A couple of hundred  Hz separation should be all we need.

I knew about the logbook but not the cwid or /m /p etc   hmm.  I am getting
out of touch. 
The only time I can see not using a log book though is when /m   but that's
just me.  I love looking back over the past 6 years at old qso's and seeing
if I have a (new one hi hi )  When I was first licensed  March the 5th
2004   everything was a new one and I think for the new breed of M6 / M3's
etc it would be a shame for them to not keep a log. 
Ok I don't log every single net on 160m or VHF for example, but pretty much
every contact still goes in the log, I bet you are the same. 

VHF is such a shame up here in the outer Hebrides, took the puppy for a walk
yesterday and up the hill I can see most of the isle of Lewis for 2m, not a
single reply even through GB3IG which I though was quite sad for a Sunday
afternoon.  There must be at least 25 operators on the island and the
repeater can work some distance out to the NW Scotland.  I don't have a 2m
antenna up at the MO and this was quite sad to not make a single contact. Oh
well.

Yes, I had an IC706MKIIG for a long while. Maybe it was the poor 
location of the filter button that made me get rid of it? HI.

Here in the UK the requirement for CW ID was removed several years ago 
and the latest UK licence is a much simpler and very cut down document. 
There's not even a legal requirement to keep a logbook anymore and the 
/M or /A or /P suffixes are 'recommendations' that people 'may' use. 
These are mentioned in the notes to the licence, not even in the main 
body...

If anyone wants to see a modern UK licence, a draft copy is available on 
the OFCOM website, go to

ready to go. However, whilst I was away, someone must have transmitted 
in 1 baud mode and, because my system was in 'Auto' it had changed to 1 
baud. I did not realise this until I hit the PTT button and wondered 
why it was taking so long the transmit!

Other than closing the program down and restarting it, I couldn't see a 
way to stop the transmission of a very long CQ string in 1 baud.

Re: [digitalradio] ROS FREQUENCY

[Toby Burnett]

I did mention this yesterday and sugested a frequency above 14.101 but I
only got 2 replies, one from you Andy saying that all digi modes should be
close, and one from Glenn who agreed with me.  I almost think, what's the
point if after about 40 messages that the issue is raised again.  Obviously
no body seems to care that much.  Sorry for being blunt but if everyone
checks their messages and actually replies with some agreement or other
ideas.  
The author of the software was quick enough to respond to my concern
yesterday !

Re: [digitalradio] Re: A new Mode !

[Toby Burnett]

Hi Glenn, yes the band wasn't there and I have a faulty power line pole that
they refuse to fix, it's about 200m from the qth and splatters S8 on 20m
until it rains, (then all quiet and I can hear a pin drop in the south
pacific lol I WISH)  

Well it occurred that this mode 2250hz wide is a little big to play in
between the rtty, olivia 500, ale etc  I see Andy has an idea too and I can
see your point to Andy.  I just think at 080 we will all get stomped on.  I
notice another chap asking about the old 109 MT63 frequency which is kind of
where I was going as I haven't seen any mt63 for ages.   Andy I understand
the wanting to keep it all close together etc but I cant see how well it'd
work.  
If we could make an unofficial experimental  mode slot ??

Keep the suggestions coming though.  I cant be the only one here that has
noticed that RTTY station at 14.081 - 2 all day so far lol

And sorry we didn't quite make it last time Glenn.

Hello Toby,
Your suggestions sound fine with me. I'm sorry that I missed the second M

I'm wondering? How wide is this mode? I'm sure the RTTY stations must hear

Subject: [digitalradio] Re: Introduction and question
 
  

Welcome to the group, Wes.

That is an interesting question, I look forward to seeing other answers. 

My answer is rather vague and generalized . I'm going to argue that "reduced
power" is not really the issue, but that reduced power is often associated
with no ALC which most point out is a key in not having a over-driven,
distorted , signal . I say "most" because not every ham agrees with this,
some thing ALC is not that much of a factor.

The prevailing view is that most soundcard modes should not be showing ALC,
PSK31-250, Olivia, AFSK ,RTTY, etc, but some modes like JT65A are less prone
to this issue. FSK RTTY is also not a mode that would be impacted by this
issue.

Consider this from "PSK Fundementals" by Peter G3PLX (http://aintel.bi.ehu
es/psk31theory.html). Also see http://www.eham.net/articles/12626 The Good
Bad and Ugly on PSK31.

"There is a problem with PSK keying which doesn't show up with FSK, and that
is the effect of key-clicks. We can get away with hard FSK keying at
moderate baudrates without generating too much splatter, but polarity
reversals are equivalent to simultaneous switching-off of one transmitter
and switching-on of another one in antiphase: the result being keyclicks
that are TWICE AS BAD as on-off keying, all other things being equal. So if
we use computer logic to key a BPSK modulator such as an exclusive-or gate,
at 31 baud, the emission would be extremely broad. In fact it would be about
3 times the baudrate wide at 10dB down, 5 times at 14dB down, 7 times at
17dB down, and so on (the squarewave Fourier series in fact)

The solution is to filter the output, or to shape the envelope amplitude of
each bit which amounts to the same thing. In PSK31, a cosine shape is used.
To see what this does to the waveform and the spectrum, consider
transmitting a sequence of continuous polarity-reversals at 31 baud. With
cosine shaping, the envelope ends up looking like full-wave rectified 31Hz
AC. This not only looks like a two-tone test signal, it IS a two-tone test
signal, and the spectrum consists of two pure tones at +/-15Hz from the
centre, and no splatter. Like the two-tone and unlike FSK, however, if we
pass this through a transmitter, we get intermodulation products if it is
not linear, so we DO need to be careful not to overdrive the audio. However,
even the worst linears will give third-order products of 25dB at +/-47Hz (3
times the baudrate wide) and fifth-order products of 35dB at +/-78Hz (5
times the baudrate wide), a considerable improvement over the hard-keying
case. If we infinitely overdrive the linear, we are back to the same levels
as the hard-keyed system. "

Re: [digitalradio] Introduction and question

[Toby Burnett]

Hi Wes, 
I have been using digi modes since I became a ham operator in 2004.  I run
an Icom706 Mk II with a 40m inv L at the moment and about 30 - 40w.  As you
mentioned you set the ALC to the point where there is just no reading on the
meter.  For all digi modes this has worked fine for me, I think overdriving
any digital signal would cause splatter and a general wide signal. I use
FLDIGI and MIXW and never had a problem.  You will no doubt here some very
strange signals in your quest for working the digi modes and it takes a
little time to get to know how they all sound.  One of the most frustrating
modes I ever heard and couldn't decode was JT6M usually used for VHF meteor
scatter and the like.  Well someone decided that it'd be fun to use it on
20m and you will here is slowly diddling along quite often around 14.075mhz 

Any problems and just ask us here and we'll help.

Interesting subject, here is my portable setup:
http://twitpic.com/y37fm

Its an eee 901 pc, an FT-817ND and a soundcard interface. I have a much
smaller interface but I dont have a picture showing that.
With this setup I can work:
- PSKmail using jpskmail (PSK500 robust really flies) and
- fldigi, lots of modes there
- xastir for packet radio through
- soundmodem, uses the soundcard and creates a virtual kiss tnc (or ax25 ip)


Of course that kiss interface can be used for other things besides aprs (fbb
perhaps).
With the smaller interface its basically a netbook and an FT-817ND (or 897
if I have power enough).
A TNC can be nice but its also nice not to have to bring it, power supply,
cables etc..

This sounds fairly complex. Why not just use a netbook? Volume-wise it's
about the same if not better after all the cables and "terminals" are
considered and if you have enough power to run digital (high duty cycle) on
the radio you have enough for the netbook.

Just a though, I am with you on the portable radio psk/rtty built in, that
would be fantastic.  Say a little FT-817 or the 897 etc with a fold out
qwerty keyboard and display.  Surely it wouldn't be hard to implement.  I
think there are now software out for psk on a PDA which is about as compact
as you are going to get.

Hi Russell,

ALE does not need a computer for sending email or 
calling other stations. There are many radios with 
built in ALE. They were expensive, but the price has 
recently come way down on some of them.

It just works, it is part of the radio's function, 
and you are not at the mercy of your flimsy laptop 
connections, or limited weight and bulk when traveling 
to a disaster zone. The limitations of small airplanes, 
helicopters, or boats could force you to decide 
whether you will bring water/food or a laptop and 
the other radio stuff. 

It is sad that not many ham radio companies have produced 
portable HF radios with built in PSK31 or RTTY keypad 
interfaces. Such a simple thing to do, but they "just 
don't get it". 

Only a few VHF/UHF HTs even have APRS built in. Such a shame.

have a couple of small valleys, here in Virginia, where the old time
populations speak a very-near, old time English, and experts often come here
to talk to them, in their studies of the language.

burn another CD Russell, perhaps you have a bad burn.

If you have a good burn, you simply load the CD from a system -reboot and
then Puppy will begin to load. It will set up basic drivers (mouse, keyboard
 video card, etc) automatically. It will give you a choice of display
resolution to use (I just opt for the default) and the language. I choose US
English despite it not being real English :>)

As you are probably aware from your other server install, the software uses
the Internet to connect to a APRS server in the Nederlands. So you would
need to activate the network/internet settings on the Puppy. That is fairly
easy to do. With FLdigi you will also have to set it up for your sound
devices. The Puppy should detect them for you and display them in the fldigi
configure soundcard area. If it does not, you would need to run the
soundcard setup from the Puppy, that is fairly easy to do too.

Re: [digitalradio] Digital modes and old husband's tales

[Toby Burnett]

I agree, Surely this chap has seen the power meter going up and down with
his voice. 
It's pretty obvious that there is a big difference between running ssb and
100%modes like psk
If you have a built in amp meter on your rig like my IC 720A  you will see
that your amp draw
Fluctuates a lot in ssb and not in PSk etc.  Big AMPS Big HEAT !!!

I used to have a little old fm 2m handie that was my only 2m rig.  Used to
actually burn my hand after a half hour rag chew lol. 

Please just think about the current draw and heat and you will quickly see
why we reduce power for digi modes. 

Of course if you have a 1kw amp then go right ahead lol but it is amazing
what you can do with a few watts on digi modes and of course CW  (the
ultimate digi mode )

Please don't use your radio to toast bread.  

Toby 

PS I run every mode with no ALC. Never had a problem.

Hi Andy...Ill add a quote from the Instruction Manual for the Kenwood TS140S

"While 100 watt transmissions are possible when using short duration 
modes such as PACKET continued operation over a long period of time 
might cause overheating. We recommend that you reduce the transmitter 
power output to 50 watts whenever using one of these modes i.e
PACKET, AMTOR, RTTY, this is easily acomplished thry the use of the 
front panel PWR control"

on my homebrew interface i have a pot that i use to set the drive to the 
TX so that i read approx 50 watts on the Revex Power meter on the 
antenna output.
was using 65 watts one night on PSK and was told that my signal was 
drifting a bit.the internal fan didnt come on but the heatsink was 
awfully warmhave since put 2 computer p/s fans on top of the 
heatsink at it runs cooler and no drift on tx

ok thats my dimes worth hi hi

Re: [digitalradio] Boot discs for emcomm/ham radio

[Toby Burnett]

Lol Very funny 

Sorry I have a friend that is a Linux fanatic and always call's MS Windows 
just Windoze. 
Then again when you see the speed of his Linux box you understand why. 

I have dabbled a bit in Linux over the years (on the same hard disk and had
problems trying to update, lost MBR) etc etc.  Main reason I don't use it
all the time on this PC (my office one as the OH now uses the vista laptop)
is A:  I have yet to be able to set up my wireless network  (I have a
specialist radio broadband as I live in a remote area and I need this to
work or I would have to cable through and this is just not viable) and also
for the software I use for work, including MS Office, I used to use open
office before this job LOL.  Anyway, on a side note.  I use FLdigi and have
flarq for windows etc. I love FLdigi.  ANother thing.  What would be the
chances of getting a wireless connection between the vista laptop and a
Linux machine.. I can't even get file sharing to work at the moment between
XP / Vista.  ICS is about as far as I have got.

Re: [digitalradio] Boot discs for emcomm/ham radio

[Toby Burnett]

 Thanks Tim, All good Info. 

I have a 200GB hard disk on this machine, but most of that is music and
videos, also it is divided, so I guess I could make an image of the main
partition. 
I may well give it a go. 
Thanks for the advise and info guys.

The image is compressed by default but essentially holds all of the 
information on the original disk drive plus some info it needs about 
the backup, etc. You can opt for no compression (faster) or more 
compression (saves space, slower) but I have only used the default 
compression option.

Earlier this week at work I made an image of a 40GB drive that had 
about 30GB used. The image size on the file server is 17GB. It took 
around an hour to create the image.

In general the disk images are good for restoring broken or infected 
hard drives. When you change motherboards or go to an entire new 
system the image you've saved is not set up to work with different 
motherboard chip sets, network interfaces, video, etc. I have not 
tried it but would be surprised if it worked.

RE: [digitalradio] Boot discs for emcomm/ham radio

[Toby Burnett]

Don't get me wrong, I agree that it can be quite refreshing to have a
default factory system.  But 
For example I was doing a re-install on Xmas eve last year and that was a
pain. 
An imaging program to back up to a flash drive or external hard disk like
the other chap said. 
Looks like the way to go. At least then you could back it up once all of
your software was in, logs and radio software, bookmarks, tools, e-mail
addresses etc and THEN back up.  I should try something like that now as my
Ahem system appears to be working fine at the moment. 

What size do these image programs make the image?  Do they really work in
the event of total system failure?  It is a rather old PC here also and I
think doing anything like this is going to cripple it.  Sorry to high jack
the thread but seems a good topic for all of us.

Actually, I find recovering from a crash with a bare install to be
beneficial. It gets rid of all the junk that builds up over a year or so. 
 
One thing that helps is I copy all install CDs to a hard drive. (Actually
they are in a version control system - Subversion - if you know what one of
those is.) With them on a hard drive the install goes faster and I don't
have to get everything installed all at once. I just add things back as I
need them.

Re: [digitalradio] How do I get started with digital radio?

[Toby Burnett]

Hi there, 

I'm working at the moment but just thought I'd say that you can get on FM 2M
Packet with just about the cheapest rig you can get and a sub standard PC or
old laptop.  I'm out of range of my packet node up here in the outer
Hebrides.  But at the previous QTH I used an old hand held with a tiny 2 TNC
and a really really old 486 DX2 laptop running 4Mb ram and free Dos.  Can't
remember the software now.  I still have it all and just need more space and
a higher antenna. 
Also when I 1st started (before I bought the tiny 2 etc) I used an old Trio
TH-205E Handi for everything, Local repeater and packet, including rx of ISS
 I made a really cruddy connection and ran it with winpac and my desk PC. 
The wee bugger got quite hot sometimes as it was on full power and a 13.8v
power supply as the battery was duff, but it worked really quite well.  I
have only used uhf a few times with a couple of friends, but you guys in
civilisation do have uhf repeaters.  I also think there are a good few 2 /
70 radios with built in TNC's and the like.  But you can get buy with just
about anything. 
As for HF, well I love dx'ing but if it's not for you then maybe building a
little 40m or 80m kit for local ragchews would be the thing. Or an old pre
warc radio.

Anyway I better do some more work now. 

Good luck and welcome back to ham radio

I let my license expire twenty years or so ago but recently took the test
for a new license and passed. I'll be getting it (an Extra) in a few weeks.
I got rid of my equipment years ago so have no radio gear. I got interested
in Ham radio again after joining the local Search and Rescue unit. Of course
Ham radio holds an important part of its operation so I thought I help out
with the Comms and get my license again. 
 
I'm retired and don't have a lot of money to spend on equipment. I know I
want to use the 2 meter band for S and R and in the vehicle when traveling.
Also, there are two repeaters in the area using that band. I know that I'd
like to use the APRS which they started using in the SAR unit. Packet radio
sounds really interesting. 
 
I spent thirty years working in Communications and spent several years
programming computers used in Comms. However, I haven't thought about radios
since I retired twelve years ago. I like the building/technical aspect of
amateur radio and not BSing with strangers in foreign countries. 
 
I know how things work and like when I started canoeing, I started with one
canoe and after a few years, I had three. But how to start? I have two
different thoughts on equipment: 1.) get something like an IC-7000 which
will allow me to use all the modes and bands to get me started. It's a
pricey option but I think it would give me a good start and can use it in
the field with SAR. 2.) Get something like an FT-8900R or just a two band
VHF/UHF rig. I can get a HF rig later if I feel the need for one. It is a
cheaper option. Since I'm not interested in DXing, I'm not sure if spending
the extra money for the HF band is worth it when getting started? 
 
Do I need an all mode VHF/UHF rig to go digital 
 
How much is UHF used? Maybe I don't need that band yet? I'm thinking it
might be useful when traveling to have two bands? 
 
Perhaps I could just get a 2 meter rig to get started. I could then afford
also to get a hand held 2 meter rig to bring on searches.

thought it would be useful if we had half-dozen more servers in North
America but having to run Linux may dissuade some.

Re: [digitalradio] Re: 40m Band what is going on???

[Toby Burnett]

Ah ha well that would point to something I guess. 
Yeah I'm aware that 20 m digi is best but there are remember very good times
to be had on the forgotten band 30m, I was talking from a voice perspective
but it seems sad that the band seems mostly unusable. 
Ahh well roll on the SF and the New Solar cycle.

Last night I heard no signals at all on 40. I thought it was because of a
solar flux of 68 and k index of 2. Today I'm not so sure what's going on.
The band changes are supposed to begin March 29th. Maybe people are waiting
for that.

[digitalradio] 40m Band what is going on???

[Toby Burnett]

I know this is digi related group but having just got my 135 foot doublet
back up after new year storms.  What is going on on 40M.  Is it me or is
there no English speaking hams on this band during the day.  Used to be lots
of UK net's on during the day and could work all over UK / Ireland and EU. 
Now we have even a ham I guess playing music at s9 on 7.092.   Has something
happened since I been away. 
The bans sounds like a CB free for all. 

Dissapointed!!

Re: [digitalradio] new -a few questions.

[Toby Burnett]

Hi Simon, 
I'm just off to bed and caught your message, 
You are right in that you should run NO ALC with the digimodes, 
I started with a simple hook up with the line out from PC into the mic
socket, and a cable from the headphone jack on the rig into line in on pc,
running on vox , This is certainly not the best interface but worked fine on
my old IC720a brick.  keep audio output levels very low.  
You will find that if you set you TX output on the rig to minimum then you
can drop the power with the computer sound output output watching an
external power meter.  I've had fun making qso's down to half a watt etc by
doing this, It's amazing what 1 watt on psk etc can do. 

I'm a bit tired right now but hope that gives you something to go on when
you wake up. 

Regards

Toby MM0TOB io68vi

Hi may I bother you with some questions.I would like to try psk31 and 
Plan to buy a kit interface soon. My problem is this,I am restricted 
To 10 watts output due to licence conditions and use a Trio ts-130s.I 
Use an alc mod to reduce the power output to 10 watts by applying 
Voltage into the socket on the back of the rig. 
 
When I use ssb the alc meter gos end stop due to this mod.I have read 
That I should reduce the transmit level on the psk interface so that 
The alc dosent move.Should I remove this mod then plug in a dummyload 
So that I can ajust the transmit level to the required alc settings? 
 
Also when I put the alc mod back in the alc reading will go endstop 
Again will this upset the transmit level? I don't think that it will as 
I would have set the transtmit level without it and I have not had any 
Bad audio reports using SSB. 
 
I hope that this all makes sence! 
 
Many thanks for your help-Simon (M3HXE). 
 
 
 
 

Re: [digitalradio] HF packet

[Toby Burnett]

Barry 
I used to listen to HF 300baud from the states and Germany, 
Even connected to Germany nodes once or twice.  That was around 14.090 - 14
110 about 4 years ago. In the past year I haven't heard a peep from hf
packet.
Think it's dead and gone in favour of olivia etc.

Re: [digitalradio] RE:Packet radio with sound card

[Toby Burnett]

Rick , 
Just on a side note, yep I have dabbled on HF packet, just connecting to
european nodes etc. Never had much success, I'd have thought NVIS on 80m be
quite good. 
Anyway there are some promising HF sound card ARQ modes coming out at the
moment, 
Like psk mail and flarq for FL digi (even windoze version).  Surly some of
these ARQ modes could be implemented into a local BBS system somehow.  Just
thinking out loud. 
Regards
Merry Xmas everyone from Dark Winter Scotland.

Similary, I have used Multipsk's packet modes on both HF and VHF with 
Success. With the advance of technology, I moved away from packet around 
15 years ago! It is just not robust enough for HF and can only go a 
Short distance on VHF, compared with newer modes 
 
What seems like an unfulfilled need is a framework similar to packet, 
With the ability to insert different modes as they are developed. You 
Would not have to keep inventing the wheel over and over. 
 
This would mostly have practical value for groups that want to set up a 
BBS system. For example, I have monitored the packets on an 80 meter BBS 
Here in my state where most of the transmissions are retries. And this 
Is during the day under NVIS conditions. A much more robust mode needs 
To be used. Then you would be able to send and receive direct or time 
Shifted messages. This is the one thing we can not do with any other 
System, but there does not seem to be any interest in developing such a 
System. 
 
At this time, it is true that a slower baud rate packet system could be 
Used, such as the software 110 baud speed available in Multipsk. This is 
Why hardware packet TNC's are a poor choice for our advancing technology 
And why almost no one uses them anymore. You are locked into a mode 
Developed over 30 years ago with no FEC or ability to be adaptive for 
Conditions. And yet, I admit that if you want a BBS system today, what 
Other choices do you have?

Re: [digitalradio] Programs for soundcard packet, 9600 baud ?

[Toby Burnett]

I've used winpack and   AGWPE sound card driver with success before on my
local BBS nodes. Not sure if this is what your after. 
Works quite well. Now unfortunately I'm not in range of my nearest Node :(
Also received packet from the iss with this ok. I've not got any real good
VHF antenna,s at the moment but give it a try.

I would like to receive suggestions about what may be available for 
G3RUH encoded 9600 baud packet, using Windows XP and Linux.

I would like to try the digital amateur satellites sometime and I have 
no 9600 baud TNC available.

In general, I would appreciate pointers for sound card packet software 
that may be useful to access the amateur satellites. I really am in need 
of an update of "what's cooking" nowadays.

I could also hear you in there, Andy, but much too close to try for
a QSO on 30M! Had a good copy on Russell, but the tuning has me a bit
baffled.
 
With my rig tuned so that I was decoding Russell and Ron, my tones
sounded like they were much lower than the other two stations.
 
How can you tell when you are right on frequency?
