Subject: AMTOR with ICOM 740?

I've been unsuccessful in working ARQ with an MFJ-1278 and an
ICOM 740 transceiver. My suspicion is that the T/R switch
is too slow, and I've heard some confirmations. I tried to
set the delay to the maximum of 90 msec in the TNC, but the
results were inconclusive.

Any suggestions?

Subject: FAQ? Internet-to-packet gateway

(If this group has a FAQ, this question is probably there. But I
have not seen one)

How can I send e-mail to a friend of mine who is on the packet-radio
network? I have his call sign as well as the call sign for the station
from which he retrieves his messages.

Also he'd like to send mail from the packet to the internet; is this
easily done in the U.S.? (I know packet-internet gateways in other
countries - my father uses one).

Thanks

I don't think the RELink will do the same thing as the CONPerm of the
AEA products.  I've used both and AEA PK-88 and Kantronics KPC-3s
and the PK-88 would reach out and re-connect when our packet cluster
disconnected me and the KPC-3s will not.  I don't know any more
about it than that.  Too bad the PK-88 doesn't have a node function
and use less power.  I like the CONPerm feature.

I am new to the KAM+ TNC, formerly a TINY-2 user. Anyway, here's
the problem. Someone told me that the KAM RELink command is similar

if I disconnect due to too many RETries the KAM+ fails to reconnect.

                             How to Use the WB7TPY
                          Packet <-> Internet Gateway

First, some brief operational notes:

(1) Messages must not contain any foul language, or commercial purpose.
(2) Messages can only be sent to countries that the United States has
    a third-party agreement.  All others will be destroyed.
(3) Messages from the internet should be less then 5K in length.
    No files should be sent.
(4) If you have questions, please do not hesitate to contact me either on
    packet radio: [e-mail]       -or-
    Internet    : [e-mail]


(5) Have fun.  Use the gateway as much as you like.  That is what it is
    there for.

                                    ------
                            From Internet to Packet
                                    ------


Send mail to the internet address of:

[e-mail]

The first line of text must contain a full packet address, preceded with the
word "Packet:"

For example, mail to my packet address, would have the first line of text;

Packet: [e-mail]


** NOTE: this line MUST be left justified.

                                    ------

Send as private mail (never a bulletin) to the packet address of:

[e-mail]

The first line of text must contain a full domained internet address,
proceeded with the word "Internet:"

For example, mail to my internet address, would have the first line of text;

  Internet: [e-mail]

*** Remember, this has to be left justified

Subject: Kenwood Tm-733 And 9K6 :-((

Yesterday I bought a brand-new TM-733E to use mainly for 9600 baud packet
(JNOS) with a TNC-2H (from Symek - DK9SJ). I am greatly disappointed for
the poor response of this radio, just because it has a "dedicated" port
for a high-speed modem and this works bad. Watching the electric
diagrams of the TM-733 I understand that this latter *can't* work well
at 9600 baud...

Any experience by other users ? Any help ?

I am really upset. My FT-736R runs perfect at 9600 and most of the friends
operating at 9600 baud using older rigs or simply modified radios have
very good performances (at a fraction of cost, compared to the 733).

*Don't* buy this radio if you plan to use it for high-speed packet !!!

I might also add that the Hustler fold-over HF mobile mast for use with
coils for various HF bands also is 1/4 wavelength on 6 meters as well as 3/4
wavelength on 2 meters.  I have been able to use the antenna on both bands
with some success.

Subject: TheNet X-1J memory loss fix

A number of messages have been posted referring to problems with buffer
losses in heavy traffic.

I have never been sure where to look as I have never been able to
regenerate the buffer loss problem in the local nodes over here, so
was reduced to reading the code and scratching my head.

I have just found ( like last night ) a possible cause for the problem.
When the node is very busy, and needs to reject a connection, and if
rs232 crosslink protocol mode 2 is not being used, the node fails to
release the memory used by the received packet.

A quick fix for this ( untried ) is to patch one byte of the code.
If this appears to fix it, I'll recompile and fix a couple of other
things and rerelease it.

To do the patch ( in thenet X1J release 2 ) debug the file THENET1.X1J
and look at the byte offset 0x13d8 into that file ( if you are using
DEBUG under DOS don't forget that DEBUG will add 0x100 so do a D 14d8
and the byte at that address should be 0x2a. Change this to 0x24. This
will cause the code to call the memory deallocation routine.

Please, this is a quick and dirty fix that I have *not* tested. If it
does not work at all, I've messed up the fix. If the problem persists
there's another bug yet to be found. If it works, I'll redo it properly.
Be aware that it is theoretically possible ( if not likely ) for very
heavy traffic alone to take a node out if used inadvisably.

Once again, my apologies and let me know how you get on.

No need for apologies Dave...your work is very much appreciated.  We have been managing
this minor problem and everyone has been quite patient.

We will be patching as soon as possible.  Our key problem site is remote and will probably
not get changed until late this weekend.

Thanks for responding to this problem, I'm sure several folks will be following with
a watchful eye.

Do you mean hear partial packets from anywhere (HTS packets) or packets
directed at the node?

Subject: What am I hearing ?

I was playing around with Hamcom 3.0 last night to see what it does, and
after copying the usual CW & RTTY on 20 meters I decided to poke around
the SWL/Military Freq's with my TS440s.

On numerous frequencies between 8 - 14 mhz I found strong signals running
850 hz shift.  I tried to decode them as: RTTY,ASCII7,ASCII8,AMATOR in
speeds ranging from 45 baud to 150 baud with Normal & Reverse Shifts.

I got nothing.. naddda.. zip.. just a screen full of garbage.  Using the
pulse timing mode it appears that the Mark pulse width is 10ms.

What am I hearing ??  I looked thru the various FAQ's and found nothing,
but if I misssed it please refer to it and I'll look there.

Thanks for the help..
