A power supply in my Yaesu 980 was no where near what is required for
Pactor.  To replace it, I ordered a Kenwood 450.  Never having had a
Kenwood HF radio, I was still able to be up and talking on Pactor in
.. get this ... 15 minutes (but I already had a hot iron).  It has so
many obvious features that lend itself to digital work that I went out
and replaced another Yaesu with a Kenwood 690.

Get the 500 hertz filter and ignore people who say not to use it with
GTOR.  It works great.

I ran extensive tests (while away from home using the 690 to the 450)
with both FSK and AFSK.  FSK showed NO indication of being superior.
I changed to AFSK so that I could parallel two KAMs and run Pactor and
GTOR on the same radio.  By using AFSK, there are no frequency problems,
the frequency for Pactor is the same as the one for GTOR.  You will find
that GTOR works great in a great band but you can't even connect in a
crummy situation.  By having both the GTOR and Pactor you can take advantage
of the GTOR speed (especially above 40 meters) and still have Pactor for
crummy conditions and noisy 80 meter attempts (the 450 scans).

Subject: HAPN 4800 Baud Modem
To: [e-mail]

I recently got a HAPN 4800 baud modem kit that I plan to install into
a DRSI DPK-2 tnc.  DRSI tech support does not have any info on doing this.
I have been told that the address in the doc's I have for the 4800 baud
modem is old.  Does any one have either the address and phone number of
HAPN. Or have any info on installing the modem into a DRSI TNC.

Any info would be appreciated.

Subject: Help for PK232 problem
To: [e-mail]

Help!...Need assist with PK-232 problem.

Have suddenly partially lost ability to communicate with my
PK232. Using Mac LC, and both ZTerm and AEA MacRatt comm software,
the TNC refuses to recognize commands from keyboard. With MacRatt
trying to startup in "Host Packet VHF" mode,the message
"Host Mode cannot be turned on, check cable and baud rate" appears.
Resetting TNC settings from dialog box (Host Mode ON, CTS flow,
9600b Port speed) does not kick it back on.
In MacRatt "dumb terminal" mode, and also with ZTerm (another
terminal emulator), I can copy received packets, and with a CTL-C
get a returned "cmd:" prompt. However, no further input from
keyboard is recognized or acted upon, other than "cmd:" at CTL-C.

The cable is ok and have triesd a substitute.
The computer and comm port is ok, and I use terminal programs
with phone modem and same cables with no problems.
Supply voltage to PK232 is 12V or better.
The four LED's at leftlight at powerup, PKT mode LED lit, CMD LED lit.
Cold power up of PK232 yields the normal startup message on screen.

Is there another diagnostic for PK 232 or suggestions for
solution of this problem? Please reply to my email address.
(Packet reply just won't work for now  :-) )

Thanks in advance.

KaGold is commercial software, but there is a demo version
available on many ham BBS's.  Sorry but I cant point you
to an FTP site.  If you can't locate it, call Interflex
at [phone] or you can probably D/L it from their
phone BBS [phone].

I use PkGold (the AEA equipment version) and I think
it is superior to all other TNC software interface
programs, by far.

I have the KaGOLD version 9.01 and I think it is the best thing going for
vanilla AX.25 packet. One word of caution (OK several): That KaGOLD test
drive SUCKS!!! I think that it is probably keeping them from getting rich
off the real software. It works, but after you have decided that you like
it and need to go back to your old software while you wait for KaGOLD to
arrive, you will find that "TESTDRIVE" as it is called does not revert
your TNC's settings to their former useful state. This  causes no end of
frustration.

KaGOLD TESTDRIVE is also representative of the software from about two
generations ago, and many of the new features that make it so nice are
not present.

Buy it direct from Interflex, the vendor. It costs the same, and I know
too many people whose disks from HRO have been unusable. Also, you get
the very latest version and they usually throw in a disk of goodies.
KaGOLD is key-locked to prevent unauthorized use. When you get it, even
if from HRO, you have to call the company anyway. They give you an
11-digit "registration number" which, when combined with your callsign,
unlocks the software. If you call them to order it, they will ship it
2-day Express Mail and will give you your registration number so that if
you have a modem you can call up their BBS and download the software for
immediate use.

Subject: High Speed Packet ?
To: [e-mail]

Hi,

I'm interested in learning about the various options available for high
speed packet radio.  I know about the G3RUH 9600 baud modem and have heard
of the AEA DSP based device but what else is there ?  Is there anything faster
than 9600 baud - what modulation techniques are used ?

Thanks,

Justin.

Well after many hours and late nights, I figured it out.....
It was my KA9Q-NOS station's escape character that caused all the disconnects
from the telnet services.  The default was control-X so I 've changed it to
control-[. Anyway my system is now up and running.....

Thanks to everybody who has read this article.

Subject: TM-733A & AEA DSP-2232
To: [e-mail]

I just got a Kenwood TM-733A and have had a AEA DSP-2232 for some time.  I
connected them up last night and it seems to work!

Questions:
1) I measured the deviation (with a service monitor) and it is 1KHz max.
What is the recommended deviation for 9600 baud packet?

2) If it is more than 1KHz, how can I increase the gain of the DSP-2232?  I
have already adjusted the one pot that is available.

3) How low of a TXDelay is possible with this combination?


Thanks!

Phil

Well, the speaker driver interrupts the cpu at >18kHz, so I guess that's
not a problem.  The only thing is that during disk I/O and the like,
interrupts are off, causing noticable disruptions.  Can you point me at some
relevant source code?  I'll see if I can merge the two.

Just find someone having experience with the above driver and ask him
how it goes in real life. Then write a driver for the BAYCOM modem
and expect improvements:
1. On receiving the BAYCOM driver should be about 4-5 times more "reliable".
   This is because the "speaker" driver probably takes the audio directly
