Subject: Amplifier impedance (was SWR & Powre Loss)
To: [e-mail]

While people are busy trying to solve Tom's problem,
I thought I'd help with the following:

Most commonly used amplifiers use variable resistance
devices, which are obviously lossy.  Which is why you
need heat sinks or blowers if your amplifier handles
lots of power.

But, there is another type of amplifier known as the
parametric amplifier.  Basically, instead of variable
resistors, you use lossless variable capacitors.  You
feed in power with a high frequency AC source.  It
isn't too common, since with all the power reflecting
around it reportedly was quite a challenge to get working
properly.  But, once you got it working, it could offer
very good noise figures before people figured out how
to make microwave transistors.  It might be interesting
to see someone implement a parametric *power* amplifier.

Simple answer...when in Canada, do as the Canadians do.  The USA/Canada
arrangement is one of automatic reciprocal licensing.  That is, when
I go into Canada I simply operate according to all Canadian regulations
using my call/VE for the province you are in.  As to frequencies and
limitations, you act as if (because you are) licensed as a Canadian
amateur.  Thus, while in Canada you can operate voice in many
of the CW segments where voice is prohibited by US regs.

Whenever you visit another country and you are granted reciprocol
licensing privaledges (either automatically as per USA/Canada
agreement or by direct application and the granting of an actual
call for the country you are in), you operate under the rules of
operation for the country you are in.

Hope that answers the question.

It might make still more sense to turn the job over to the ARRL,
a la the proposal for Canada. India has ALWAYS used this system,
and so far as I know it has always worked well.

Subject: Field Day
To: [e-mail]

I was reading the Field Day rules in this month's QST.  It appears as
if Field Day is theoretically open to only hams who are "members of
the "ARRL/Canadian Field Organization".  Does this mean that only
Canadian hams and members of ARRL are (in theory) participants in
Field Day?  The rules specifically indicate that "Foreign stations may
be contacted for credit, but are not eligible to compete."  I always
thought that Field day was an International affair!

Does it really say "members of"?  I believe you only have to be
"located in" the ARRL field organization.

Nope, its a US/Canadian event.  You can work DX stations, but they
are not eligible to enter.

I'm not sure.  Here it is copied from p. 132 of May's QST.  I hope
I don't get a letter from Mr. Imlay for this.  :(

1) Eligibility: Field Day is open competitively to all amateurs in the
ARRL/Canadian Field Organization (plus Yukon and NWT).  Foreign
stations may be contacted for credit, but are not eligible to compete.

=================================

Are US hams who are not ARRL members "in" the ARRL field organization?
If so, wouldn't the phrase "US/Canadian" be more appropriate?  It
certainly appears to me as if all Canadian hams are eligible but only
US hams who are ARRL members can compete.

Subject: FT-41R weirdness
To: [e-mail]

Hi all -

  I just acquired a new Yaesu FT-41R, and it exhibits a very
bizzare problem with a local repeater.  When using the repeater,
the audio drops out intermittently.  The repeater output carrier
stays on.  Specifics:

1)  The repeater needs a PL tone.

2)  The audio on the input to the repeater (output of the unit)
doesn't drop out, nor does the PL tone drop out as verified
by my FT-530 in Tone Squelch mode.

3)  The audio is "hot" on the FT-41R.

4)  Unit has been checked for loose connections, weirdness like
that.

5)  I am hitting the repeater with a good signal -- when the
audio is there, it is full quieting.

My weird analysis:

The "hot" audio is causing the PL tone to distort and/or get clipped
by the voice, and is causing the local repeater to drop audio.
(I don't know what would cause the repeater to drop audio but
keep carrier -- I have asked the owner, but no reply yet....)
Thus, by backing off the deviation, this should be fixed.

Before I go and play around with the insides, anyone else have
any other possible explanations for this weird phenomena?


Thx in advance,

Ken

A friend of mine is moving to southern Oregon soon, and I am wondering if
anyone knows of a linked repeater system (on any band) that would link from
roughly Los Angeles to Ashland, Oregon. The only system that I know of is
CONDOR, but I don't think it connects all the way up to Oregon. Thanks for
your help.

In Oregon the State Police used to have bumper stickers that say
something like "Monitor CB ch. 9, 17, 19"  Of these, channel 17
would be your best bet.  Its the Interstate 5 truckers channel and
is used on other roads as well.  In the metro areas 17 is full of
Mud Ducks, echo boxes, and other weirdos.  I assume the truckers
just turn off their radios when passing through.  Out in the country
its much better behaved and you will be assisted promptly if you
are sincere.
Nobody seems to listen to 9 because its really boring.
I take a CB along when traveling away from populated areas because
there are so few hams out there in the boonies that even if you can
hit a repeater there won't be anyone listening.

>Is there a "standard" simplex emergency freq on 2m, 220, or 440?

Try 146.52, 223.50, 446.0  I can often raise someone on 146.52 while
on road trips but I wouldn't count on it and certainly not the others.

        o 16 channel w/ scan

We would also like to acquire the programming cable for these.

Bill,
  I have five of the MT1000s that cover the 154Mhz region that you
  are looking for.  They are 16 channel w/scan, just like you want.
  I also have sources for the programming cables.
  I can sell the MT1000's for $850 each, including shipping.  If
  you need the rapid chargers for them, I have them for $75.00
  each.  These radios are in EXCELLENT, LIKE NEW condition!  If

I would like to be able to use my computer along side, or in close

(radio frequency interference). What are the most efficient methods
for reducing RFI.

I have 486DX2 50 MHz, Super VGA monitor, and a laser printer.
All equipment is less than two years old and presumably well shielded.

I'd like to be able to use my computer while I'm on the air, logging,

Any suggestions?

*THE* SKN (straight key night) is New Years Eve.  However, There is a
newer, more frequent version of SKN that has been largely
taking place every (well, maybe only 'many') Friday nights,
starting variously around 0400 UTC (earlier  in the
winter) on 80 and 40 meters in the Novice subbands (3702
and 7102 khz).  The emphasis is both to encourage the use of
straight keys, and to engender interest in the use of Morse,
elmering people, and the general gathering of people interested
in "low-key, relaxed community" on amateur radio.  Besides, why
just wait until New Years Eve?  Straight keys can be used more
often than that!  The hope is that you'll converse, tell yarns,
and just sit back and enjoy (plus maybe exercise that arm).

Try it.  Get on and call CQ CWIST DE YOURCALL K and tell a story.

Unfortunately SKN occurs on New Year's Eve which is why I've only participated
once.  Any nite or day can be Straight Key for me however, since that's all I
have to send with anyway.
Maybe we could have SKN on Monday, Bug nite on Tuesday, Paddle nite on Wed.
and Keyboard nite the rest of the week since that's what most seem to be
using now.
