Subject: Help on H/H & TNC problems reqd
Date: 4 Sep 92 08:08:42 GMT
Organization: Digital Equipment Corporation

I have a packet station consisting of the following equipment:

Rig : Alinco ALM203E H/H
TNC : BSX2 (TNC 200 clone)
PC  : AMSTRAD PPC640DD

I think I have a problem with the above which  I think might be
stemming from the H/H I use. It`s a relativery old H/H but has given
me good and reliable service, however I have noticed that it`s use 
seems to result in the loss of quite a few packets on my local frequency.

By this I mean that the TNC DCD light is illuminated but the CON light does
not flash to indicate that the packet has been rx`ed properly. It also seems
to be very susceptable to the frequencies of the tones, as I have two nodes
wroughly equidistance from me but their tones are very slightly different, 
rsulting in one being rx`ed ok the other only very occasionally.

I have used a FT290R in same setup in place of the ALINCO which has fixed the
problem.

My main question then is, I guess the problem may be due to two things - the squelch
open time of the RIG and also the de-emphasis, Is this correct?, Has anyone else had
this problem with the rig or can suggest any mods?? Would fitting a H/W DCD to the TNC
and running with open squelch help, can it be done on my TNC, has anyone got any details
of a mod or design for a DCD.

I hope you can help cos this problem is very fustrating...

    I do have a router sitting on the Internet and that talks to our local
amateur tcp/ip group.  Since 44.x.x.x is not routed my direction (and I
wouldn't want it to), amateurs need to telnet into my unix box (kumr) and 
then they can telnet out to the Internet. Mail and news can be routed via 
kumr to/from the Internet and the amateurs that are in my local area.  I
haven't set up a worm hole at this time. If there is interest, I would
like to look into it with folks.

Tone twist, the phone company term for the effects of incorrect 
pre-emphasis/de-emphasis, is an annoying problem that plagues many 
packeteers using the microphone input and speaker output of their 
voice radio for packet. There are a couple of solutions. The best 
is to go into your rig and insert tones directly at the modulator 
stage and extract tones directly from the discriminator stage, 
bypassing the bad emphasis networks in the radio.

The second solution doesn't require modifying the radio. Simply
put RC networks in the input and output leads that compensate for
the poor emphasis networks in the radio. You'll need a test set
of some sort to know when you have the total curve just right. Or,
you can just play it by ear on a separate rig until everything
"sounds" right. That's usually close enough.

Hardware DCD and open squelch is almost always a good idea. TAPR
has a kit that plugs in the modem chip socket to implement this.
It's cheap and simple to install.

...hm, I've been on packet for nine years, now.  Seen it change.

To tell the truth, I'd view a shutdown of this kind as a positive
event.  

When all is said, if I need timely, content insensitive data 
communications, I'll use the Net, dialup or real PSNs.

Packet, as is, is an interesting pastime, but nothing to get upset

The gateway I can help you with, but I require all people that access it
to have their ticket. With the new code-less licenses it is very easy to
get one. You can actually do it in a couple weeks. If you are interested
in how let me know and I will try to get you in touch with the proper
people. Once you have it, we can do a lot about getting you in touch with
your dad.

When you get your ticket send a message to gateway-request@arasmith.com
and I will register you with the gate and send you the gateway instructions.

There is an easy way to give them full access.  Find yourself a
cheap AT and configure it to run KA9Q NOS, specifically the WG7J
or PA0GRI varients. They are available on ucsd.edu.

Attach your TNC, in KISS mode, to the AT and attach the AT to the
Unix box via a slip line.  You can set up the user permissions in
the /ftpusers file on the AT so that only the users you specify
can get on.  Your users then just telnet from the unix box to the
AT, login with their callsign and, if you use the wg7j or pa0gri
versions, connect out via the radio using their own callsign.

As an added bonus users on the radio side can also get to your
Unix box.

We're planning to do this locally with a 386bsd box via ethernet,
a novell file server (running novell TCP/IP and NFS) and
G8BPQ/AA4RE.  The NOS box will be the radio handler and allow
connections to these services as well as cross band connections.
(We have multiple ports on the BBS now.)

I see two problems with this. First since many hams will be out enjoying
the week end any way, doubt they would miss the network for a weekend
and second the ARRL is in  Newington I doubt that a Phoenix shutdown 
is going to bother them.. How about a simple letter writting drive

If they were hams, they could very well be control operators of the
station.  They would be operating it on remote control.

Probably the best mode is to make the thing function like a node.  The
thing would source packets that appear to come from the user's call
(but via your station).  Theoretically, they could just set their call
on the TNC though and still be legal.

  Come on now, you are in a very unusual position.  Here in east Texas,
it's unusual for adjacent sites to be very far apart.  In effect, you
are telling me there are no sites between Dallas and Houston.  Alaska
has different problems.
  Perhaps you will be stuck with 1200 baud for a while.  The routes
that carry high traffic from many sites will be the first to convert.
That probably means both coasts, especially California and the NorthEast.
  Over *most* of the country, I don't see a need for 400 mile links.

Subject: Shorting Nicad batteries to revive them...
Date: 23 Aug 92 22:28:06 GMT
Organization: University of Illinois at Urbana

According to one explanation of why Nicad batteries die that I've heard,
small metal whiskers grow across the electrodes with use, and eventually
develop a short which prevents the battery from holding a charge or from
being charged.

The solution is to charge the battery as best is as possible, and then
*short* the battery terminals for a brief (?) time which is supposed to
melt these whiskers (and I suppose the metal flows back to the electrode
of origin).

Has anybody done this?  What exactly have you done?
Must it be done on single cells?  I am trying to do this on a battery
pack.  One pack won't take enough of a charge to warm up the 
shorting wire, while another battery pack heated up the shorting wire 
so fast I couldn't hold on to it (I guess you should use pliers!). 

Is less than a second of shorting enough?

(I'll let you all know if it is after I charge this battery and run
it down again.)

Thanks.

Summary: I am buying a HT - which should I get and why?1
Keywords: dual band handi talkie ht
Date: 26 Aug 92 05:25:39 GMT
Distribution: usa
Organization: IBM, Austin

Hello!

After reading through all the doublespeak and non-information of
manufacturer spec sheets, It's time to get some expert help. I'm in the
market for a dual band (2m, 70cm) handi-talkie and need some solid
information from people that have used them.

I've been looking at the ICOM W2A, the STANDARD 558, and the KENWOOD
78. I have not yet got any info on the YAESU. From what I read in the
forums, Kenwood has a poor service department, so I'll pass on their
gear. The ALINCO dual bander seems to have some software problems, so
again I'll pass.

Questions:

Of the remaining hardware (plus any I've missed), does anyone have any
good reason why I should buy one over another?

I would like to do high speed packet (9600 bps +) with the portable. I
realize that I'm asking for miracles here, but does any handheld dual
bander have a low enough phase distortion and proper bandwidth to do
this?  Better yet, if it works, what's the setup?

Also, what about mods to open up the RX/TX? I know the W2A can be
opened up quite a bit. Others?

Nobody in our area has a Standard 558 - what does it come with and how
well do you like it? The trade press and Standard disagree on this, so
I'm interested in what users have to say...

Offbeat Questions:

Has anyone taken a commercial V.32bis modem and made it into something
that would be useful for packet use? They're getting cheap enough now
to make this feasable. I expect some modifications to the modem guts
and possibly a "backend" of some sort would be required.

Any recommendations for mounting an Antenna on a Mazda MX3?

Closing:

Thanks in advance for everyone's help. If I get a good response, I'll
post a summary so others will benefit.

Yours,

Hi ...
     On our PBBS we run an open phone line.  Anyone can call the PBBS
and read and send traffic, licensed or not.  Anything that a visitor
sends is held.  The sysop changes the message that was sent to go out
under the sysop's call as third party traffic.
     There's the rub!  You have to have a third party agreement between
the two countries.  I am not sure who Wales has a third party agreement
with.  I do not believe they have one with the U.S. (I will admit to only
checking when the traffic demands pouring through all the back issues of
QST to find the latest list).  Disregard, I did have one on the disk, we
do not.  Hence, doing it through a U.S. amateur would be illegal.
     You are in a great time period for ham classes!  They will be starting
all across the country!

Bradley,
I don't recommend shorting the cells out as you are doing.  I doubt that it
helps, and I am afraid that you and/or your equipment may be damaged by doing 
so.

    After years of trying non-scientific (i.e.  pass/fail) means of
rejuvinating my ni-cad's I have adopted the following.  I try to charge the
individual battery or cell "normally" with a 1/16 C rate. If it is in a pack
of cells I open the pack and isolate the cell with jumpers, alligator clips,
or straight pins under the insulation.  If that doesn't work I give it the
shock treatment.  I happen to have an old RS CB power supply, it puts out 2
Amps continuous and 3 Amps peak at 12 Vdc.

    I apply the output from the power supply to the offending cell(s) until
the circuit breaker pops.  At that time I measure the cell voltage and, if it 
is anything but 0 V, place it under normal charge for 16 hours.  If the cell
does not show any voltage I repeat the shock treatment a few more times.  If
it doesn't pick up I figgure that I have fried it and toss it out.  If it was 
a cell in a pack I remove and replace the bad cell.  I seem to have a fair
success rate with this method, and have never had a cell explode or change
shape.

    An alternate method which I have read about but not experimented with
sounded interesting:
    The author used a scale to measure cells before use, and after they would 
no longer charge.  He found the latter cells to be lighter than they were
originally.  He injected distilled water till they were their original weight 
and claimed that most would begin functioning again.  Sounds feasable, no?

    Anyway, welcome to the world of the rechargeable cells.  Be sure to let
everyone know how your experiments come out!
