Yes, if you redesign/retune all resonant circuitery to new xtal.
Since QRG is lower you will need new coils etc.

To: [e-mail]

All I can tell you is that on TV(here in Europe) there is plenty of ads
pushing 'an intelligent battery charger' with a microchip which charges
ordinary batteries.
Perhaps they have found a way of charging ordinary alcalines through
intelligent charging (whatever
that may be). Sometime ago I was told that it couldnt be done. One hundred
years ago, someone also said we cant get to the moon.

Yes you can do 6M from Coast to Coast but its very rare. Sporadic E or
Es max single hop range is 1400 Miles. In the 3 seasons I've been on 50
Mhz Double hop to the Atlantic has happened 4-5 times. Thats what make
50 Mhz so interesting... You NEVER know what will happen next! 73s...

    Ah, now that's a very interesting (and untrampled) area. Most of the
really keen, usually ex-naval, CW operators I know eschew narrow CW
filters and use their ears. They complain at great length about the poor
sound of most radios and point at older valved units that had very much
better in-band linearity.

   The designers in Japan have learned of the importance of better front
ends, but still assume that once past their 9 MHz filter, there is no
remaining need for any care. The AGC controlled stages seem the worst
culprit. Wondered about doing a very linear IF at 1.4 MHz, where I have
a lot of really good filters, probably a long string of push-pull
grounded-gate stages with photoresistor gain control. Bought a bag of
ORP12 cells, but haven't yet got a supply of bright enough LEDs. I need
to run them at the bright=low R end of their range as their response
slows a lot at the dark=high R end.  Scrounged some samples of a monster
LED that will work as an outdoor torch, LEDs are being aimed at the
vehicle brake and indicator light market, so there ought to be some
along at reasonable prices fairly soon ( is there any prize for wild
optimism?)

   Another one from my personal niggle pile is lousy audio amplifiers
that latch short spikes into far longer pulses.

Subject: How to Identify Channel Master Control wires
To: [e-mail]

One of my friends disconnected the control wires from his Channel Master
Controller and forgot the correct way to reconnect them. The Rotor is a small
TV type mounted with cheap hardware and is rusted in place.
Even after the nuts are chiseled or drilled off the rotor the mast will not
move up (which it has to be done in oder to release the rotor) because
the mast is rusted to the support bearing in the top of the tower. Can I
determine the correct order by taking resistance readings or by trial and
error ? There are three wires so there are 9 ways the wires could be
connected,  would trying the different combinations harm the rotor or
controller ? One of the combinations we tried would cause the rotor to turn if
the beam was disconnected but it was not strong enough to turn the rotor and
beam (the beam is easy to turn by hand). Would the rotor turn at all if the
wires were connected wrong ? Thanks Gary WB8OFU.........

I would appreciate pointers to any mods for the Icom 281H or 2GXAT?

I've checked several ftp sites but came up empty.  At the ARRL convention
there was a 281H taht was setup in the demo mode that did some fancy things
with the display but the rep wasn't sure about the key sequence so any
info on this would also be appreciated.

And it never fails to amaze *me* how many people make nasty generalizations
and unfounded criticisms of others and drop references to how much money
they have to spend in the hopes of impressing everyone, and then back down
in record time claiming their posting was "misunderstood" when called onto
the carpet.

No, I want ICOM to take my number and call me back when they've got time
to talk to me.
I'll even foot the bill.

I just want the same quality customer service out of ICOM that other
companies magically manage to provide while still turning a profit.

I think it's about $1400 w/ tuner, and $1225 w/out from R&L in Ohio.

This may be off-topic, so I'll limit myself to only $0.03 worth.

I wanted to be a ham for the thrill and adventure.  After the Loma
Prienta Earthquake in October 1989, a friend, who is a ham, was
telling me about all he did working with ARES/RACES in the aftermath
of the earthquake.  I knew that was something that I wanted to do.  A
secondary reason was that he and I could chat and not have to be in
the same room or tied to a telephone.

As for ragchewing, I think it depends on the region.  In California
where I was, there wasn't too much problem with ragchewers tying up
repeaters.  Well, except for one instance where a mobile ham needed
direction and an OF (Old Fart) ham explained for a full minute that he
didn't know where his destination was located.  In Florida, where I am
now, it is relatively densely populated by OF hams.  OF hams are easy
to spot, IMHO, because they are the only ones who NEVER EVER wait for
a courtesy tone and thus time out the repeater, or they talk for so
long they they alone time out the repeater, or they talk at length
about mullet fishing.  Unfortunately, I haven't spent much time since
being licenced in other parts of the country so I can only speak from
my limited experience.

I think the original poster doesn't understand just how understaffed the
FCC is.  Nor does he comprehend the fact that the paperwork load
recently doubled in this area due to the the re-occurance of license
renewals after a 5 year respite.

First point.  The FCC staff has been cut back to the bone, and then some
over the last 15 years.  To illustrate the point, there were something
like 11 engineers in the local field office in 1980.  There are 4 now.
And you have to realize just how much area these 4 guys are responsible
for!  They have to do all marine inspections, commercial site inspections,
etc. along with other duties in Northern CA.  From my way of thinking, it
is a miracle they just don't get completely snowed under.  Gettysburg
is in the same boat.  Further, they are in the midst of updating a 1960's
computer system to a more modern networked workstation system.  This will
help, but the migration path caused some pains.

Lastly, the work load thru this section literally doubled.  There are about
as many renewals being processed right now as there are new licenses.  they
didn't HAVE renewals last year!

SO...if you would like to have your taxes hiked, then by all means, I'm
sure that we can accomidate 4-5 week turnaround!
