I know three hams who have the 22at and they all say that the lack
of a backlit keypad is the main drawback, otherwise they love 'em.
It will work for packet, but keep in mind that under any high-power
high duty cycle ops, the rig will get VERY hot.  run as little power
as you must to make a good packet contact, and your rig will thank you.

you may want to check out the yaesu mini 2m ht (ft11r??) as i have
heard nice things about them as well

73 and good luck

My apologies if this is part of an FAQ, but I

I would appreciate information on where I could

The encoders are a simple plug-in option. The decoders are only available
to Generals and higher licencees. Some of us early Tecnicians also have
this option. ;^)

I would like to find the instructions for

The reason you're confused is that the fright-mongers can blithly say,
"Radiation is going to kill you," while those who try to make _rational_
statements haven't the luxury of such blanket statements.

If history is any guide, the tens of thousands of living hams are proof
that, No, it's _not_ going to kill you, or make you sick, or make your hair
fall out, or any of the other horrendous things the fright-mongers use to
attack everything technological.  Is that plain enough?  Nobody has ever
established any link between the radiation from operating an HF amateur
radio station and any health-related problem.

Go enjoy the hobby and stop reacting every time some Luddite screams "doom"
at technology.  :-)

To: [e-mail]

Once upon a time, I ftp-ed a Morse program for the Mac -- I think it was
even called "Morse Tutor," although I could be wrong.  I also seem to
recall it was written by a German.

I need to find it again!  Any suggestions as to sites?

Thanks and 73,

Subject: PKGOLD Enhanced PROBLEMS
To: [e-mail]

        TO ALL HAMS USING PKGOLD ENHANCED

  I have ran into a problem with the latest version of PKGOLD Enhanced
  with Pactor.  It seems to exit the program with the following:

   DISK ERROR 100
  DISK READ error
  record -1 in GOLD.BD

  This is found on the screen after the program dumps out. Timing of the
  exit from the program is random meaning 5hrs or 1hr after loading the
  program and has even done it while in the connect mode as well.  It will
  leave the TNC open so that the buffer fills up and no connects can
  happen.  Having the ***SAME*** version for the Kantronics TNC (KAGOLD)
  for use with the KAM+ and the KPC models and using the ***SAME*** computer
  ***WITHOUT***  ONE problem at any time and I can leave it without worry
  PKGOLD I can not do that at all. (also tried it on other computers with the
  same results)

  One other problem I have notice is that opening a connect window it is
  full of junk chars which should not be there. ?????????? (PKGOLD ONLY)

  Interfex claims it doesnt have any problems and thinks it mine.  Why can
  I run the same versin for the Kantronics TNC without any problems but
  yet I can not run the PKGOLD (extra cost) with the AEA products.
  (PK-232, PK-88, PK-96)


  Also how many commercial programs leave out the manual because you have it
  with your other versions of gold

  Has anyone seen or have the so called DUALPORT PKGOLD yet.

Subject: Question about power supply for HTX-202.

The nominal voltage of a fully charged car battery is 13.8 volts. That's
why most fixed supplies put out that voltage. In a car, the charging
system can increase that voltage to 14.5 volts, sometimes even 16 volts,
so the radio has to be able to work with that if it can be run off the
car. All you care about as far as supply current rating is concerned is
if it can put out *enough* current. The radio will only draw as much as
it needs, so a bigger supply is not a problem.

This is a basic Ohm's Law problem. Model the circuit like this:

  ----------------
 +|              |
Bat 13.8V       Radio 6.9 ohms
 -|______________|

Assume the radio is a resistor (it's the load), and that if the radio
normally needs 2 amps at 13.8 volts, it has a resistance value of 6.9
ohms. Now it doesn't matter how much current the 13.8 volt supply is
*capable* of producing, at 13.8 volts it can only push 2 amps through
a 6.9 ohm resistor. I=E/R or 13.8/6.9=2 amps. The only way the supply
can push more than 2 amps through the radio is if the supply *voltage*
is increased, or the radio resistance is somehow decreased (it can do
that by outputting more RF or AF power). Let's assume a auto charging
system voltage of 14.5 volts.  Now how many amps will be pushed through
the radio? The answer will tell you why higher voltage batteries allow
HTs to transmit more power. (Remember P=I*E)

Now obviously solid state devices have an upper voltage limit, and
exceeding that limit will destroy the device via voltage breakdown
and current avalanche. So you never want to use a supply that has
a higher voltage than the equipment is rated for. However, most
equipment has a built in *safety* margin of about 20%, so you can
*usually* apply a voltage of about 16.5 volts to a 13.8 volt rated
radio without destroying it. A few tenths of a volt difference from
rated voltage should never be a problem.

CE>Hi Ken, I have a stupid question. Does anybody actually send Farnsworth-

CE>why learn sounds in a way that will not be encountered in operation?

The reason is that nearly all electronic keyers are not designed
to send code that way, though there are a few.  As you probably
have been told, Farnsworth code is meant to force learners to
recognize a character by its complete sound and not by counting
dots and dashes.  As your speed comes up you will eventually be
sending/receiving code in the 15 to 20 wpm range and that matches
Farnsworth character speed.

The Supermorse program for learning code does use the Farnsworth
method.

Oh, really?  Then why did that new ambulance I saw the other day say "Ford" on

They must have more than one set of exam tapes.  The Element 1A tapes we
use at our VE sessions (ARRL tapes) are _no way_ 16 wpm characters!
They're _slow_.  I couldn't say if they're actually 5 wpm characters, but
definitely not 16.
