Subject: Help!  Noise on a KDK 2030
Date: 28 Aug 92 13:11:16 GMT
Organization: Lenoir-Rhyne College, Hickory, NC

hi folks...

I have a KDK FM-2030 2-meter mobile radio that has developed
an occasional noise problem.

The noise first appeared last weekend on a trip through the mountains.
after an hour of low-power simplex with my traveling companions, I was
told that I was transmitting mostly noise, like if I was holding the mic
out the window.  Plenty of signal, just lots of noise.  Receive audio 
was normal.  I un-hooked the KDK and switched to the HT.  Later in the 
day I used the KDK for the entire two hour trip home without a hint of noise.  

The noise re-appeared yesterday, after enough air-time to make a contact,
but went away after two transmission attempts.

The solder joints in the mic connector are solid, the connector is in tight, 
the antenna connector is tight, the rf meter indicates a normal signal level.

I recently replaced the rf output transistor.  the original KDK mic went 
bad years ago, and the unit has been transmitting fine for two months 
with the mic off of my old Teaberry "T-Scout" cb.  

Any ideas?

The easy way to get a cheap and nasty 12V supply is to go into a CB shop and buy
one. It should be no more than 20 pounds. Tandy may be able to supply but are
expensive. (You probably know Tandy as Radio Shack). All UK supplies are 220/240 V
as there is no use whatsoever in a 110V one.

   Actualy I beg to differe.  There was a very public trial of a drug runner

   the Feds had illeagaly tapped his cellular phone.  The courts not only slammed

   Cellular is like CB or Ship-to-Shore.  This is an open broadcast on public
   airwaves and thus there was no reason for them to assume that it would be
   considdered "private".

Reasonable people may argue this way but still the law makes it
illegal.  Bad spelling aside you are either wrong or missing some
facts of the case.  Are you sure it was cellular?

  I just wanted to add, if you were to do all the mods to the
th-77, that this is a nice feature to stop someone from accidently
keeying up and transmitting incase you were out of the amateur
band, i.e. 148.01~177 or like 450.01~510.00 and monitoring(since this 
model will transmit out of band if the HT is modified correctly.

Well, I don't think there are ARES/RACES branches in YU4. I am not

kind of thing.

Drills can be valuable, particularly for newer hams like myself
(licensed 2.5 years). We had a disaster drill in town about 1.5 years
ago, and I was riding around town making up emergency situations
(the road is blocked because of flooding; we can't get through here),
listening to other "pretend" situations, and --most important -- learning
proper net procedures. When the hurricane hit New England last August
and I was out with a Red Cross disaster assessment team helping people
whose homes were severely damaged, I was amazed at how much the real
disaster sounded like the drill. The drill definitely helped prepare me.

Do you need a drill every month or every week? No. Do you need a bunch
of self-important people with special emblems, logos, etc.? No. Should
local police and others have their own good emergency communications 
systems? Yes (in fact, our radio club donated some very good, new
radio equipment to our town's fire department). Should the ham community
try to maintain good working relations with the local police department?
Yes.

Just my opinion ...

In our town and immediate surroundings, the frequency is our local

Our hurricane in New England last August certainly can't compare with
Andrew, but it was a serious situation. Members of our club were
assisting both the Red Cross and Civil Defense. Power was out in almost
the entire region, although there were pockets of electricity. On the
repeater, people were able to report important information such as 
where there was a gas station still open, where there were dangerous
power lines down, etc. Cellular phones could have handled a call from
a truck to the police/power company, but the rest of us couldn't have
heard the information. Ham radio was definitely a help.

Yes, I also listened to commercial radio and TV broadcasts when I could. 
The wise person tries to have as many alternatives as possible in an
emergency. Ham radio, when used correctly, can be an important one.
And, as I mentioned in my last post, right now it's virtually the
only way that ordinary people can get information to and from loved
ones in Bosnia-Herzegovina. The YU4 hams are doing truly incredible,
superhuman work to try to help people communicate there.

                  Of UHF Connectors on 9913 and other sins
                                on *HF*.

I have been reading about the horrible sin of using PL259 on 9913 and
the effect it has on family values.  This discussion started with a
query about using PL249 on Belden 9913 at *20MHz*.  Consider for a 
moment the following set up:

   ==================-------------============================v^v^v^v+ 
    50 ohm coax        Z ohm line    50 Ohm Coax              50 Ohms|
   A                B             C                           D    ///

The impedance progressing from 50 ohm load to source:

   At D  50 ohms

   At C  50 ohms

   To figure out the impedance at B, consider the Smith Chart (if you
   do not like Smith Charts then formulas found in many handbooks,
   including the ARRL Handbook, can be used) normalized to
   Z ohms.  50 ohms will be at 50:Z swr circle and the impedance at
   B can be read off once the length of line BC is known.  Now a UHF
   connector (only the length of Coax from which the braid is stripped 
   during assembly is relevant) is about 1/2" long or about 0.3 of an 
   electrical degree long at 20MHz.  So now move along the constant 
   swr circle towards the source for 0.6 of a degree (36 minutes 
   that is) away from 50 ohm point and you have the the new impedance at B.  

   Now construct a circle on a Smith Chart centered at 50 ohms and 
   plot the impedance B on it.  Move along the constant
   SWR circle (a strong magnifying glass and 0.1mm pencil lead might
   be useful in this excercise) and you have the horrible mismatch
   at A.
    :) :) :) :)

Gary's comment hits very close to my thoughts on the matter. To be honest, it
does not matter one ha'penny-worth (cent/dime/nickel-worth to most of you) to
me whether pro-words or pro-signs are used ... but I note with interest that
no-one has mentioned the matter of pro-words being language dependent whereas
pro-signs are not. OK on VHF all parties will probably speak the same language
and English is "Universal" but in noisy international HF voice contacts I can
see good cause to use pro-signs.

The Radio Shack phone in question, according to the catalog, dosen't
use digital encryption as do properly equipped Motorola radios.
The RS catalog describes the phone as using 'frequency inversion'
a well known and easily countered technique.  So, it's very questionable
how secure these phones are.

On the other hand, by paying a few more bucks, one can have of the truly
digitally encrypted phones, such as the 'Tropez.'  According to 
Popular Science, this phone operates in a new 900mhz band allocated for
the use of these phones.  I recall also of hearing about a similar, but
competing model called I believe, the 'Escort.'

A word about Motorola encryption.  Through my association w/Civil Defense,
I got to play with one of the local Public Service(police,fire,pub. works),
radios on the trunk system.  These awesome HT has digital voice encryption
built in.  I notice about a 250ms to 500ms delay between transmitting
the word 'test' and hearing it in the receiving unit(simplex).  Also
their is a noticeable decline in the readability of the voice, in digital
mode, although the signal is still a 3-4 in readability.  Lastly, if you
can ever get ahold of these units, put two of them together and try to
create some audio feedback while in digital mode.  The sounds are quite
interesting.

John-

As you might expect, Hams were involved with communications as soon as the
storm subsided.  I live in Brevard county, where the weather was beautiful
while Miami was being bashed.  The Brevard RACES and ARES groups sent teams
of operators to the disaster area immediately.  As I understand, they were
required to take their own food and water, in addition to comm gear.  Their
efforts were coordinated through the Miami area Emergency Management
offices.

Here is a bulletin that I picked up on Packet, several days after the
storm:

--- End of messsage #8665  to ALL    from N5AUV  ---

According to reports, most of the many repeaters in the South Miami area,
went off the air as a result of the storm.  As suggested, many of the local
Hams had their own problems.  If they weren't already involved with an
organized emergency group like ARES or RACES, they may not have been able
to contribute much even if they tried.

I don't know if any of the out of area Hams are still on duty in the
affected area, but suspect they have returned home by now.  I hope to hear
more on tonight's RACES net.
