  I started the digitalradio Yahoo group ten years ago (next month)
  because ,at that time , there were many groups dedicated to particular
  modes of applications but no generic groups where anything related to
  digit modes was ok to discuss.  For the same reason, I have started
  SDRlist.  A Yahoo group for discussion of any software defined radio.
  Currently there are lists for Flex radios, SDR-IQ, SDR-14, Sofrock,
  Winrad, CW skimmer, and many more.  There is also a forum for
  SDR-Radio.  These lists can be quite good, but it can be a a little
  awkward if you want to poast a question about a  rival product or
  application.  So, if you have any interest in software defined radios
  for amateur radio or SWLing, please consider joining via
  http://groups.yahoo.com/group/SDRlist/  .  Please help build this new
  group in to a thriving on-line community where useful exchanges of
  information and opinion will make the group a leader in SDR.

Re: [digitalradio] Digital busy detect

2009-11-24 Thread WD8ARZ
Scamp busy detector as used in Scamp at the time of the group testing I 
was part of, was NOT the end all of busy detectors. Finding a setting of the 
threshold was very difficult. Too sensitive and the throughput operation of 
Scamp was poor due to being held up by the threshold trigger. Not sensitive 
enough and it did not perform at times when you knew it should have. What 
worked for one type of band condition for awhile, did not work well during a 
different type of band condition.

Personally witnessed operators that would intentionally come on frequency 
and put out signals solely for the purpose of triggering the busy detector 
to stop operations. When Scamp operations were not active, they didnt seem 
to be active on the frequency. Start Scamp activity and some of the same 
lids would start up again with just enough activity to activate the busy 
detector.

End result was the agreement to not use it as it was not living up to 
expectations  and stayed that way through the shut down of the group by 
the author.

Re: [digitalradio] Getting serious about ALE for non-encomm digital hamming

2009-11-22 Thread WD8ARZ
Good to see this post Andy.

For those concerned about having a full blown ALE station that scan, though 
it is preferred, it is not fully required.

You can go to an established ALE channel and stay fixed. Make a long ALE 
call, and the scanning station(s) that can hear you will respond to you on 
their scan on the frequency you are fixed on (depending on the kind of ALE 
call you make, you could get multiple connections). In other words, the will 
find you if propagation / signal quality permit.

This way you dont have to have an antenna for all bands, and a fast tuner 
for scanning on those bands.

When you dont get an answer by the specific station or group call you made, 
change to another established ALE frequency and try again  etc etc 
until you get the connection. Then communicate your schedule or other needs, 
and use other modes for a more dynamic exchange of information.

Keep in mind that another key feature in addition to those pointed out by 
Andy, is that the scanning ALE stations also collect information about what 
stations are heard on what frequencies, when and what signal quality. That 
information can be used to establish communications quicker, or to determine 
a schedule that would be best based on on those history of the stations info 
collected.

There are also ALE / Voice channels that are established where short ALE 
calls are made to determine if a station is on frequency, and to then 
quickly switch to a voice mode to communicate on that same frequency  
these are stations that are manned for those activities.

Using HFN Stations, short text messages can be sent to email address and 
cell phones to arrange for communications schedules, or provide information, 
such as telling your wife that you are ok and will be in touch soon  etc 
etc You can email to non hams, they just cant communicate back along the 
same path you did, so provide the info they need to reach you by some other 
means.

Re: [digitalradio] Which radio ?

2009-11-22 Thread WD8ARZ
Many rigs can be brought into play for a variety of services and be a joy to 
own. This thread focus's on digital modes, so .

I love my TS-480HX, and it is used on the base for 24/7 digital ALE
operations. Its better performance due to NOT having two meters and four
forty bands improves the HF side. It is my main mobile rig. The extra power
of the HX allows running at lower power, such as 100 watts, at near full
duty cycle that a normal 100 watt rig would not do well at. Same for
operating in hot mobile situations  running digital in a hot mobile can
be handled by this rig. The HX version has two cooling fans along with the
normal 480 heavy case fin cooling design. The IC-7000 runs hot just for the
voice duty cycle .

Down load the TS-480HX/SAT In Depth Manual at the link below, and read it
right from Kenwood experts. Then you will understand why no two meters and
four forty is desirable in the design of an HF receiver. An exception is the
TS-2000 with separate modules for the other bands, but it is known to have a
different HF design that doesnt have as good a performance on HF bands as
the 480 design.
http://www.kenwood.com/i/products/info/amateur/software_download.html

I miss the DSP auto notch of the MP when using the 480. That is the one
feature that amazes me as to why it wasnt included.

Yes, I plan on keeping the 480 for a long time, and maybe getting another 
 but I would not part with my Ft-1000MP with the dual I.F. cascaded 
physical filter design though... hi Hi HI

Another ALE operator has a radio of interest for digital, the Icom IC-718. 
She points out that a few minor mod's are useful and should be incorporated.

Well said, well done, and well thought out - Thank You!

Ham's have been running ALE for a long time (at least a decade for me, boy 
does time fly!), and I am not aware of anyone running ALE who has ever 
received a Notice from the FCC. Our early evaluation work with ALE started 
out with a special letter to the FCC that included all the callsigns that 
were going to be running ALE. We received no restrictions about it then, and 
none since  even after numerous communications about ALE to and from the 
FCC about ALE operation and its unattended nature that is inherent into its 
original design and intent.

Appreciate this great forum, and thanks to those here that I have seen their 
callsigns on the ALE HFN system from time to time. We can use the 
participation, and encourage many more to come on board.

Hello Dave, I was there during those scamp beta testing adventures too
. and I remember that part of the evaluation. Various levels were played
with, akin to a sensitivity level. Bottom line to me was that when the level
made it 'work' ie, not transmit when the frequency was 'active', throughput
dropped way back Remember those that would intentionally put 'activity'
on the frequency to kick in the transmit control system so we had zero
activity with scamp 

No cynicism involved at all, just the real world.

2008-08-08 Thread WD8ARZ
Dave, enjoy your software and respect that effort very much. Really 
surprised to find your comments that continue the mis-direction from the 
original email.

It is obvious in my original message that no twists or personal comments 
were directed at anyone, that there is no intent to counter new ideas, or 
that there were limits to directions anyone could take with software. It is 
obvious that the intent of my email was to not forget we can use what we 
have, use it as circumstances and time allow, and it was clear that there 
are issues that will remain with us for some time to come. There were no 
efforts to cover all contingencies, represent all modes of training, fit in 
with all view points or provide the right or wrong way of things should or 
shouldnt be done. These are short emails that dont have to be manuals that 
measure up to peer reviewing hobbyists that cant get off their obsessive 
critique compulsions.

It is clear that some responses were done in a personal way, went out side 
the topic intent, and have distracted the thread into a direction no one 
enjoys and is counter productive. Which seems to be a trend some do with 
regularity. It isnt always what is said or done that is important, but how 
it is said or done that can make a difference in how folks are motivated or 
feel encouraged to participate.

To keep putting others on the defensive seems to be a rather awkward way to 
garner support for ones view points and my email was not about point of 
views. It was about using what we have, that there are a lot of options, and 
there are bandwidth and time issues. No modes were selected, be it digital, 
analog, voice, cw, satellite, cable, internet, landline, laser, etc etc etc 
etc  ...

There was intentionally room to go in any direction one wants to use what 
currently exists, but it is obvious that one needs to be prepared to use 
what is here today, as best possible with the inherent limitations.

My response here is not just a defensive reaction to criticism. It is a 
response to try and prevent others from mis-representing the intent of my 
original email. Silence sometimes is used to avoid contenuation of being a 
target, and I was tempted to do that (and now will), but I had  to make it 
clear that I by no means approve of the habitual twisted spins some throw 
out in their verbal spars that do nothing to the betterment of others or the 
topic.

My apologies to others. Moderators, please feel free to block this thread 
from further negative progression.

WinDRM, DRMDV and FDMDV, all written by Cesco Lanza, HB9TLK, used a codec
that was developed for the US Department of Defense and NATO. Rights to
various forms of the codec are held by several companies; they have never
been released for free distribution and use by hams. According to Gary
Pearce, KN4AQ, the companies have winked at ham radio use for several
years, but a recent complaint caused the programs to be pulled from the
download site. Lanza did a quick rewrite to use an open-source codec, and
now WinDRM and FDMDV are back, Pearce said. DRMDV, an intermediate program

[digitalradio] HFLinknet Feedback and Tips

2008-06-22 Thread WD8ARZ
Hello Rick,

Ok, lets see if we can steer you to some good future ALE contacts.

As you know, a sound card has to measure up to the digital task it is being 
tasked to perform. Not all do. That topic I will leave to others that have 
covered this so well in the past on different forms many times.

Next it is important that the transceiver being used is calibrated. Doesnt 
take too many Hz off frequency to not work well. One hundred hertz is too 
much for example. Many of us have ran into that one at one time or another, 
right? A couple calibration methods are at:
http://hflink.com/calibration/

The ALE Channel Zero site is a great place to meet other Ale operators and 
find an Elmer:
http://hflink.net/qso/

Dont forget that the HfLink forum is a source for information and links to 
other Ale operators.

As with any computer system, make sure your computer uses the latest 
software and fill files.

With all the Ale contacts going on world wide, I suspect there are some 
other issues with your Ale communications problems. Changes in any system 
are expected, and the ALE network is no exception. One of the nice parts for 
Ale systems is that you can scan and find those stations that you can work. 
Real-time status of all HFN Pilot Stations is provided both on the web and 
on the air (via hourly station identification). If in doubt about the Pilot 
stations you can link with, simply set your radio to receive scan all the 
listed primary data channels, and then link with the station(s) on the bands 
that are best. NVIS is OK if you can find it, but not needed.

For your having problems I suspect you need to fine tune a bit more. The 
nature of a good ALE signal requires a better level of transceiver 
calibration, soundcard accuracy, and passband flatness than most other 
digital keyboarding modes do.

In time I am sure you will work out your issues. Many have and can assist 
you too, on and off the air. Here is one source of setup information:
http://hflink.com/pcale/setup/

Some of your concerns have been addressed before. Keep in mind that all this 
is a work in progress. Over time the system will continue to grow, software 
and features will be enhanced, and it goes with out saying, that bugs are 
being worked on all the time. just like any other system as it goes from 
conception to being routine.

Keep trying, hang in there, and I am sure you will get it worked out.

 If anyone is having luck with the system, can you share your exact

I am usually attend regional Field Day efforts with serious
 operations, I'm often the digital guy that gets invited so the
 organization can get digital-related bonus points.

 This year,  the combination of needing to remain close to home due to
 family health issues and my past views that I miss out on all the
 operating fun by giving lectures/demos, has caused be to think about
 doing Field Day at home.  I figure that I really need to find some way
 of not depending on my mains power supply for all my amateur radio
 operating.  So, Field Day looks like a good target date for trying to
 find some emergency power.

 I am not going to buy a generator, too much of a hassle and too much
 noise for my neighbors.  I thought about battery power, still
 thinking about it, but recharging a battery has to be thought about
 since the ARRL has some limits on how they are recharged.  Wind power
 and Solar panels are appealing but they looked to expensive to me.
 Seems to me that true emergency communications preparation ought to be
 simple and cheap so that many stations would be activated , if needed.

 So, assuming a battery powered laptop computer is part of the stations
 (and thus is not a problem) what inexpensive options are there to
 power a modern HF rig using digital modes at 5 watts or less ?
 Perhaps something that can be used to xmit and receive for 2-3 hours
 and then be re-charged without mains power in a reasonably quick
 manner ?   I did think of pedal power , good exercise too, but that
 may be too difficult.

engine, has a ultra bright, non-glaring, 5 inch, TFT Touch Screen, and comes
with cable to interface to the Kenwood D700 / D710.


End result is a selection of individual gear that operate totally as
separate units, Base, Mobile or Portable. However they can be configured to
give the HT remote control access to the dual band mobile leaving the HF rig
alone, or using the dual band mobile as an interface to the HF radio, the HT
has remote control and transmit / receive access. Due to Katrina, the FCC
granted legality for using Sky Command for such HT to HF operation.

As a bonus, APRS is supported in this system, and in combination with the
AvMap G5 Navigator, GPS information can be fed to the D700 / D710 or the HT
as needed. APRS info is sent to and from the G5 making for a seamless
interface that doesnt require a computer. Under the right interfacing and
some limitations, packet radio can be supported. Using digital protocols,
digital modes on a computer provide emergency texting / email until local
systems improve. The navigation / gps functions of the G5 are a must in
emergency situations where knowing where you are and how to get to where you
need to go can other wise be a challenge.

suggestions are in Emergency power digital station options for Field Day ?

[digitalradio] Digital station options?

2008-05-21 Thread WD8ARZ
Many HF rigs use relays for bandpass filter switching, and other tasks.
Unfortunately when changing bands, these relays cycle to the configuration
needed for each band range. When using software to scan the bands, these
relays are being cycled with each band change request from the software.
Some HF rigs allow using a dual VFO mode that the Software can use to scan
in such a way that the band relays are not cycled. Software uses a bandpass
relay selection that allows receiver performance during scanning, but
switches in the relays for band activity and transmitting. This approach
saves relay wear and tear.

List of Radios for ALE:
http://hflink.com/hardware/

PCALE will function with almost any amateur or commercial HF radio. For
rapid channel scanning, PCALE (and MarsAle)uses the computer-to-radio CAT
interface to control the transceiver frequency and mode.
Some transceivers are better suited to ALE service than others, for various
reasons.
The following transceivers have internal circuitry that is optimum for fast
Quiet Relay Scanning and Sounding with PCALE (and MarsAle):

ICOM
IC746, IC746PRO, IC7400, IC756PRO (Milspec 1030E-DSP), IC756PRO2, IC756PRO3,
IC765, IC775, IC781, IC7800 (except mixer relays), PA relays handled by use
of SPLIT VFO, all support up to 2 ch/sec scan rate, newer models at 9600
baud up to the 5 ch/sec and those that can do 19,200 baud at 10 ch/sec scan
rate
KENWOOD
All Kenwood models after, but excluding the TS-440, PA relays handled by use
of SPLIT VFO, all support up to 2 ch/sec scan rate, newer models at 9600
baud up to 5 ch/sec and those at 19,200 baud at 10 ch/sec scan rate
YAESU
FT-920, FT-990 with SPLIT VFO (FT-890 with special QS/S modification) all
can do up to 2 ch/sec scan rate.
HARRIS
Harris RF-350 family: RF-350, RF-350K, RT-1446 URC, AN/URC-119,
AN/URC-121(V) PA relays handled by BYPASS command, supports up to 2
ch/sec scan rate.

other software programs, such as a Dream Audio Mondale program, or other
digital programs such as ALE or Multipsk. In other cases a program works
fine in XP but due to audio handling differences in Vista, they dont work
there. Frequently the work around is a virtual audio handling program such
as VAC. With VAC installed programs see additional in and out audio lines
that can be selected to provide the audio link paths needed.
Virtual Audio Cable - http://software.muzychenko.net/eng/vac.html

Last but not least is getting performance out of that computer to perform
reliable digital mode operations. Steps that can be taken are:

Dont run any programs that are not needed, especially audio video programs
(as in cd / dvd programs).
If your system has performance options, and may laptops do, choose the
faster performing options over battery saving if needed.
Turn off all program auto updates.
Turned off all program search auto routines, especially auto find operations
for your hard drive.
Forced network to use G mode when wireless.
Defrag hard drive.
Adjusted priority of programs so they get more priority to run faster (task
manager, select program, right click and set program priority and insure it
has access to all cpu's).
A biggie turned out to be turning on Hard Drive write caching.

[digitalradio] HAARP and Moon Echo of HAARP received well in South Bend, Indiana 6.7925

2008-01-19 Thread WD8ARZ Comcast
Copied 6.7925 HAARP and the Moon Echo of HAARP real well in South Bend, 
Indiana using a SDR-IQ on a 10-160 Carolina Windom Antenna.

Also copied the signal of a carrier around 0503Z that tuned / swept into the 
frequency. Thought it was the HAARP signal looking for the sweet spot, but 
now not sure.

Did record a 50 kHz spectrum to the hard drive using the SDR-IQ, and the 
HAARP primary signal and he moon reflected signal were both recorded. They 
can be heard and seen on the 3D running spectrum display.

Other signals coming and going up and down the band from the HAARP frequency 
are also copyable in these files. I limited file size to below 45 Megs per 
file in the series of files covering the time period. The one with the 
moving carrier is about 22 megs. The first half of the time period I 
couldn't hear HAARP echo's due to the interfering signal on the low end of 
the frequency, but great copy after the frequency cleared up.

No copy at all on 7.4075 due to the Dentro Cuban Jamming Command and Radio 
Martí as identified by Glenn Hauser.

[digitalradio] Vista Digital System Navigation for Hardware Setting and Info

2007-10-20 Thread WD8ARZ Comcast
Navigating can be such a pain when going from xp to vista. Both worlds have 
there plus and minus properties and I am not advocating or bashing either. Just 
happen to use em and other operating systems, and I am glad to share that 
experience.

In Vista and using the default Vista Control Panel:
===
To Manage / View your System Hardware so you can see what your com ports are:
Control Panel
Additional Options

Device Manager
View hardware and devices

Now you will have the Device Manager panel and will see a com port selection 
'if' you have any com ports active. Open the com port icon and plug in and 
unplug your Rigblaster Plug  Play. You will see the com port and info come and 
go with that activity. (Please note: the usb ports on your laptop will have a 
com port number assigned to them in Vista that will not match with the same com 
port number if that same laptop boots with xp. I have a dual boot xp/vista so 
was surprised to see that ...hi hi) Don forget you can change com port 
properties including com port assigned number if you want to.
===
In Vista and using the default Vista Control Panel:

To Manage your Sound Options navigate the following -
Control Panel
Additional Options
Hardware and Sound

Sound Icon Gives you access to all your sound options. Under 'Change system 
sounds' you will find under the Recording tab the Microphone Icon. Double click 
that Icon and you will have the Microphone Properties panel. Under custom you 
can enable / disable Microphone Boost (I havent had to do that on my two vista 
laptops, they are enabled) Of course Levels tab lets you set the Microphone 
volume level.


Or:

Choose Classic View in the Control Panel, and you will have the XP control 
panel icons you might be more comfortable navigating around with.

Dont forget to have the Rigblaster Plug  Play drivers installed for Vista.

  Subject: [digitalradio] Re: NBEMS HF testing frequency suggestion


  I had a number of problems with the system. It booted fine. I got 
  both programs running.

  I have a Rigblaster Plug  Play which is a USB serial port. I could 
  not determine what serial port that would be to setup the C-IV for my 
  Icom. I needed that for PTT. I also tried to follow the directions 
  for setting up their rig control but (1) where is $HOME/.something? 
  I opened the file viewer, clicked home but saw nothing that looked 
  like that directory. 

  I could see no input. This is a laptop and I only have mike input. I 
  could generate output from the sound card so I think the sound card 
  was found okay.

  I decided to pass on this for right now and switch back to Windows. 
  This is the first use of the Rigblaster since I got arrived on 
  Wednesday. It is working under Vista using DM780 and HRD. It is neat 
  using the C-IV to control the rig!

  The only hassle is that the mike input is to hot so overdrives the 
  sound card. Guess I need to put a pot to allow adjusting it. 

  Since this is my first digital experience I do not know what signals 
  I am hearing to select the digital mode. I did listen to a PSK-31 
  QSO. But while I can hear and see other signals I cannot get them to 
  decode.

[digitalradio] Digital Vacation Plans

2007-08-25 Thread WD8ARZ Comcast
Storms gone, back on the air!!

Program problems seem to be worked out now (transmit audio levels and atu 
operation).

Next I will load up the bbs software and see how that goes.

Will be on and off the air from the base from time to time all weekend as I 
test software and move the system from the base to the mobile setup.

On vacation the next two weeks, yahoo!!  Will be a mix at home in South 
Bend, Indiana, in Alabama and in Tennessee.

Plans are to mix all ham activities. Hf voice, hf ale, hf aprs, vhf aprs and 
Pilot station... from mobile and fixed locations in various areas. Will be a 
true test of the entire system and the ability to move from base to mobile 
to portable with the various modes. Will be one hundred percent battery 
operation all locations and modes. Various GPS hardware / software will be 
used and tested with these modes. Will be using the AvMap Geosat 5 Navigator 
with a five inch screen to display the APRS information when not using the 
laptop ( http://www.avmap.us/index.php?swt=01 ). This way I can run Vhf / 
Uhf APRS with out any laptop computer in the system while I use the laptop 
for HF Ale and APRS. A cable plugs from the D700/D7 into the G5 and provides 
GPS info to the equipment, and waypoint plotting of all ham station 
broadcasted Aprs / Gps data on to the touch screen. Separate GPS units are 
available to feed GPS data to each radio independently if needed (using 
Deluo Universal GPS modules). Deluo provides versions for usb laptop 
interfaces, and Kenwood D700/D7 direct plug in models.

Will provide ssid information when I have that worked out. Have the HF base 
Ale and Aprs (TS-480HX), HF mobile Ale and Aprs (TS-480HX), Vhf/Uhf Dual 
Band mobile Aprs (TM-D700AG) and Walkie Talkie APRS (TH-D7AG).

Will be testing walkie talkie to hf linking on this trip too .

[digitalradio] WD8ARZ and upcoming ALE Week Status

2006-10-08 Thread WD8ARZ
Looking forward to the upcoming week for ALE ON THE AIR WEEK 2006 (13-23 
OCT)

In preparation for this I have done the following:
--
Have put up a new 10-160 Meter Carolina Windom
Bought a LDG AT-200 Pro tuner
Bought the Kenwood TS-480HX 200 Watt Transceiver
--

Thanks to Steve N2CKH, I now realize I need the LDG AT-200 PC version of the 
tuner. (... as only the AT-200PC is really suitable for ALE, the other LDG 
models such as the AT-200PRO is not in BYPASS during receive whereas the 
AT-200PC is set to such via both PC-ALE and MARS-ALE software ...)

The LDG AT-200 PC version will be ordered on Monday and will be here in time 
for the weekend ALE fun.

Reason I have made the changes is I have been concerned about the ALE burden 
on wearing my beloved FT-1000MP relays to death, This concern has limited 
how often I am on and stay on with ALE.

What I hope the benefits with the changes are:
1: TS-480HX doesnt use relays in the bandpass filters (uses switching 
transistors, but does use relays in the lpf filters)
2: TS-480HX has excellent cooling and better continuous duty transmit time 
and load support (even with the dual fans not running).
3: With the 200 watts, I can use it if needed, but it allows for running 
lower power and having better cooling and transmit duty cycle time even 
more.
4: Using an external tuner transfers the relay cycle mechanical wear to out 
side the transceiver.
5: The LDG AT-200 Pro tuner has memories, and once stored settings for a 
frequency are in memory, it makes those tuning selections even faster than 
other tuners . except the PC version under computer control). I am 
keeping the Pro version because I want a good fast tuner for HF operations 
with out using a computer.
6: LDG AT-200 PC under computer control is the best way to go for ALE, and I 
very much appreciate Steve supporting the manufacture on bring that about!

Only thing missing at this time is a ALE version that supports the TS-480HX 
and LDG AT-200 PC tuner. Currently waiting on replies to Steve, Bonnie and 
Charles for software access to support this system in time for the upcoming 
event.

Side benefits for the TS-480HX is I am going to pair it up the new HiQ 5/160 
mobile antenna purchase and have lots of fun this winter with HF mobile. Now 
it looks like I need to get a laptop for mobile ALE eh ???   Hi Hi

Hey, good luck to all this weekend. I am looking forward to it!

[digitalradio] One of the interesting upgrades out, is for the HK-232 / PK-232 series of TNC's

2005-02-20 Thread WD8ARZ

One of the interesting upgrades out, is for the HK-232 / PK-232 series of 
TNC's. Not only does the HK / PK232 series of TNC have excellent passive hf 
filters, now they are further improved with cascaded DSP filters.

The ability to take the load off of the CPU is a great reason to use a TNC. 
There are also several software programs out there that recognize the 
upgraded TNC's and switch them in and out of TNC / Sound Card Mode 
automatically.

For example the Airmail program for Winlink uses the Pactor TX/RX and Dsp 
functions of the HK-232 in Pactor One mode.

The interface to the Ham Rig here is a HK-232 (kit form of the PK-232) 
upgraded with Timewave ( http://www.timewave.com/  )MBX (mail box), DSP, Low 
Power Chips, and the PSK31 interface switch modules. In essence when the 
PSK31 interface module is switched to sound card mode for programs like 
Scamp, the Tnc is bypassed and transformer isolated adjustable audio 
amplifiers for input and output to the sound card and ham rig is switched 
in. This same circuit is used when in Tnc mode, but then the internal modes, 
filters and dsp are used rather than any computer sound card programs. Thus 
I use the HK-232 with PSK31 in Sound Card mode when using Scamp, but use it 
in Tnc mode when using Airmail for Pactor Mode One receive and transmit only 
using the Tnc and internal Dsp support.

When ever possible, I always choose a TNC function when available for a mode 
over software. Heck, I can put the TNC into a mode that will leave me on the 
air with a radio for vhf packet email, and receive email with no computer 
running. When I fire up the computer there it is  do that with software
