Depends.  Who said you knew about the input being there in the first
place?  After all, it IS a simplex channel.  Are you expected to buy a
spectrum analyzer and watch the whole band to see if whatever
frequency you land on keys a transmitter somewhere else in the band?
I think not.  Would you tune the band when operating on 52 splx to see
if you were keying someone's odd repeater?  I sure wouldn't.  Hey, did
anyone even figure out that split?  Where would you come up with
something as lame as 1.02mhz shift???

By the way, I was quite impressed by the number of people who
responded privately to that statement, saying they agreed, but
wouldn't dare say so publicly.  I respect their privacy and appreciate
their support.

Subject: 1.2GHz on an HT -- how far?
To: [e-mail]

Hi!

A few of us with experience only in HF/VHF were discussing operation in the
1.2GHz band and specifically just how far (or not) one could transmit with the
typical HT operating on 1 or 2 watts with a rubber duck style antenna.

It's obviously going to be very line-of-site sensitive, but in practical
terms, in a moderately flat and forested area, are we talking hundreds of
yards or a a couple miles?

I'd like to hear from some people with practical experience in settings such
as this.

Thanks!

I have had wonderful results with Icom products over the years.  Kenwood
is right up there too.  My entire hf station is Kenwood.

Stick to either of these brands and you won't be disappointed.

>73, Ron...WA7GFE

Here's what I did...
I put on BNC connectors designed for RG213. These are close enough in size to
the 9913 to work OK. You will never get a perfect seal out of the rubber gasket
clamp-type connectors, because the air-core coax tends to collapse as you
tighten the connector. So, basically it comes down to gooping it. I smeared
some RTV into the coax-connector joint, and around the threads of the clamp. I
then spiral-wrapped two layers of electrical tape over the entire connector
assembly, the final layer going from the bottom up, like shingles on a roof,
continuing a few inches up the coax. Needless to say, you have to plug
everything together before you start wrapping. Pull the tape very tight so it
conforms to the surface. Lastly, point the antenna end of the 9913 *down*. This
way any water that gets in stays put. You can always pull the connector and
drain it out, if necessary. You will probably need a short piece of RG58
between the 9913 and the antenna to do this. I've had no problems for about 1
yr of New England weather.

A couple of things: I know many hams say don't use RTV because it's corrosive
over time... So far no problem, and all the connectors are nickel-plated brass
anyway. You may want to use that coax-seal putty instead. Also, as far as
condensation, my 2m antenna is chimney-mounted, and the 9913 runs up alongside
the chimney, enclosed except for the last 3-4 ft. Therefore, your milage may
vary if you run it up a tower.

Is there a packet pakage for the Mac?  I'm looking for the program for a friend.
The best way to get me is though email.  He is also looking for a fiel that
lists call signs on a Mac.


And for me can you tell me the the proper Internet path to send a email over the
packet system to a packet user?

Does anyone know of a source (mail-order, probably) for aluminum or
copper sheet in small quantities?  Or heavy duty chassis of the same
stock?  I need some on the order of 1/8 inch thick for a grounding
bulkhead for my new QTH.

To: [e-mail]

Fellow Hams:

     I am currently looking for the mod sheet for the new Kenwood HT,
TH-79A. I know it is a new radio, but I wonder if anyone has decoded it
from the Japanese yet. I am a MARS member, and I would like to use it on
our repeater activities. Unfortunately, Regional MARS has not seen
through to sending my revised pedigree, so Kenwood won't talk to me.

     I understand it will do many tricks that would make your dog
jealous, I just want the limited outband mod.

Anybody that can help, please email.  --->[e-mail]

I know this isn't quite the right place to ask, but what part of FCC
rules governs the use of 49MHz walkie-talkies? I'm looking for stuff
like power limits, antenna limitations, rules on broadcasting (baby
monitors do this), etc. Thanks. By the way, will a simple crystal swap
move these things over to 6M or is it not this easy?

Is the splice done so that the braid is connected around the entire
circumference of the cable?  How about sealing it from the elements?
Is heat shrinkable tubing acceptable, or would it be possible to
use some 1/2" PVC tubing with silicon to seal the cable/tubing gap?

Actually, I suspect that the individual technique used (tapes vs computer)
isn't nearly as critical as the mnemonic technique used, eg., associating the
sound of the letter with a picture of the letter, instead of counting dots
and dashes.
