To: [e-mail]

Is there any way to make an Alinco DJ180T stay on a busy channel
instead of automatically resuming scanning after 5 seconds? Also, is
there any way to lock out channels? (It seems that if you upgraded
to 200 memories, scanning without lockout would be rather difficult)

Thanks in advance for any light you might be able to shed.

I recall recent mention of an East Coast Drake user group which meets
on 75m on Saturday. Unfortunately, the time and frequency slipped
off the spool before I grabbed it.

Can whoever knows post or email when it is?

Thanks

Posting, since others may be interested.

According to information someone sent some time ago it is:

    3.865 Saturday @ 8:00PM Eastern

Note that I've not been able to verify this from Colorado this summer.
Hopefully I'll be able to participate this fall when the QRN settles
down a bit.

BTW, anybody interested in setting up a similar net in this part of the
world?  Surely there are other plains/inter-mountain Drake enthusiasts
out there!

: Thanks

Welcome.  Always happy to hear from other Drake users.

Contact Charley Snodgrass ([e-mail]).  I ran into him at the
Dayton Hamvention where he had a table set up in the flea market. He has
come up with a DSP development system (dsp compiler software) to use with
Analog Devices based PC sound cards (like the Cardinal and Orchid).  You
can mail him at:

Charley Snodgrass
P.O. Box 10393
Cedar Rapids, IA 52406

Don't know if he has any neat filters or demodulators coded up yet, he is
selling the DSP compiler, editor, debugger (much like the borland IDE
Integrated Development Environment) for about $80.

Surely you jest. Conducting business (weather on an Autopatch or not) is
illegal on Amateur radio. The test is: Do either you or your employer
benefit.

Get yourself a copy of part 97, the FCC rules governing the Amateur
Radio Service. Codes and ciphers are specifically excluded. See
97.113(d). ALL communication MUST be in plain language. (CW is
considered to be plain language, not a code).

It is really difficult for me to understand how ANY ham (that
passed the necessary tests required to become an Amateur) could think
what you want to do is allowed. This is a joke, isn't it?

It is against the rules to operate a cellular phone in an aircraft in
flight...  This is an FCC rule, not an FAA rule...  As a charter pilot, I
have to inform my passengers that the use of their cellular phone in the
aircraft is prohibited...

And why is this...  Because from altitude, a 1/2 watt cellular phone can
lock up hundreds of cells for miles around, instead of just the one or two
that it can see from the ground...  It has been estimated that 700 or so
airborne cellular phones stratigically placed around the country can lock
up the whole cellular system nationwide...

Tom, buddy. I service the coast guard electronics in the pacific northwest for
a private contractor. Take my advice please. If you go out on the water get
yourself a vhf radio. A lot more people dissapear on the water than you ever
hear about. Sorry to get heavy but watching people cry and the anguish
involved all for the want of some sort of reliable communication. It gets to
you.

I have been able to open some battery packs by breaking them open.  The
advantage is that there is no kerf, that is, gap caused by the cutting
instrument.  I have found the best way to break the case is to put it into
the vise and apply pressure in the right spots.  It usually breaks, or cracks
along the glue seams.  You may have to do some additional prying with a
screwdriver to completely open the case.  Some battery packs use very strange
cells that I have not been able to locate.

Hope this helps.

Perhaps a viable transmitting antenna for HF would be ridiculously long
and impractical in a handheld?

At least two Japanese companies make some.  Tokyo HyPower Labs makes a
40/15/6m tribander for SSB/CW.  And jcomm makes single-band HF SSB/CW
transceivers.  The biggest problem with such devices isn't their low
power, but the efficiency of any kind of antenna you can comfortably use
as an HT.  Connected to a dipole or other "real" antenna, these units work
as great QRP rigs.  In fact the jcomm  gizmos have quite a cult following.

It's worth it. They're pretty cheap, anyway. But do the mods in the mean-time.

Because as a skipper and as a ham, you're doubly legally protected if what
you need to do is call 'Mayday, Mayday, Mayday' and all you have is a non
type-accepted rig. And if you're life were really in danger, you could
always pitch the radio in the drink when help arrived, and not feel the
loss too acutely, if still worried about what the CG might say.

On the other hand, in a normal boarding/inspection your ham radio
handheld, once shown to be a ham radio rig and not under USCG
jurisdiction, is a lot less interesting than are your flares,
PFDs, and toilet.

The Coasties have been conducting a crack-down on unlicensed marine
VHF. A ham rig is about the only way I can think of to have last-ditch
marine VHF frequency coverage without the expense of paying an exhorbitant
'user fee' to license a transmitter that you never intend to use. And
yes, the Coasties will cite you if they find a turned-off marine
VHF with no evidence of transmitting, and no license. It probably violates
every rule of probable cause, due process, and evidence, but hey,
it then becomes your problem to go through the process of having
it thrown out of Federal court. And getting the Coast Guard to make
amends is like getting any other branch of the military to do so.

Bill's right. The water gets mighty big and lonesome when the mast comes
down and the rigging wraps around the prop shaft, and that sharp rock
is looming ever closer...
