Thanks to the Northern Ohio Amateur Radio Society, Northern Ohio DX
Association, Ohio/Penn PacketCluster Network, DL1HBT & DXNL, DF4RD,
KW2P, WB3JFS, WB3LHD, K4CEF & Southeastern Cluster Group, W8GIO, KF8VW
and VE3CDX for the following DX information.

3W, VIETNAM. 3W4VL was reported active on 28025 and 14025 kHz between
0000 to 0200z on December 12th. The operator stated he was UV3HD and to
QSL to OK3IA.

5R8, MADAGASCAR. George (5R8GW) has a new call sign as of December 8th.
It is 5R8DG. He has been heard on 24952 kHz around 1453z and 21260 khz
at 1600z. QSL via F6FNU.

5X, UGANDA. 5X5WR with Baldur at the key, summed up the CW side of the
operation on 21025 on December 9th:  The station used by Baldur was a 
FT747, Windom antenna, 100 watts, on Lake Victoria.  He reported making
8500 CW QSOs and said "DL Dxpedition to Uganda QRT QRT QRT" at 1942Z.
CW QSLs to DJ6SI direct, SSB QSLs to Medical Assistance Radio (M.A.R.) - 
Box 1223, D-8209 Scholssberg Stkn. 1 - Germany.

6W, SENEGAL. Apparently, Rich's, K3IPK, stay in The Gambia was short. 
He was again active this week as 6W6/K3IPK. His length of stay is still
unknown. Check 7007 kHz around 0545z and 28025 kHz around 1600z.

EP, IRAN. A Canadian station reported that EP2AS was active during a net
operation on 21157 kHz around 1200z. (Hopefully his activity will move 
up the band.)

FW, WALLIS ISLAND. FW/Y31XO and FW/Y58IO have been quite active on 18
and 24 MHz as well as 7 MHz. Activity will continue until the end of the
year. Check around 1100 to 1230z on or around 7010 kHz. Also, check
24900 kHz starting around 1800z and 18100 kHz around 2345z. QSL via Y58IO.

KP5, DESECHEO ISLAND. (UPDATE) From a news release sent to OPDX by Bob,
KW2P. The KP5 team plans to depart from KP4 on December 28 at about 1130z
(before sunrise). They are hopeful, prior to 2300z, that all stations will
be active from Desecheo. A lot depends on sea conditions and the associated
problems of transferring the equipment from the boat to shore. The list
of operators and call signs are as follows: Randy N0TG/KP5, Dave W0RJU/KP5,
Murray WA4DAN/KP5, Ron AA4VK/KP5 and Bob KW2P/KP5. Activity will be 10-160
as follows:
  CW   - 1830, 3505, 7005, 10105, 14020, 18075, 21020, 24900, 28020
  SSB  - 3790, 7090/7150, 14195, 18125, 21295, 24940, 28395
  RTTY - 3620, 7085, 14080, 18015, 21080, 28080
QSL all call signs to N0TG: There will be a new QSL address for N0TG: 
Randy Rowe N0TG, P.O. Box 891, Desoto, TX. 75123. (Please, direct only,
S.A.S.E and NO BURO)

P5, NORTH KOREA. (A Christmas treat or a belated Halloween prank?) WFWL!
A station signing P51AA has been quite active every day like clockwork on
15 meters mostly, but there have been 10 meter spots reported. The station
was heard on 21022, 21330 and 28550 kHz between 2200 to 2345z. Some of
the reports on the operator's behavior range from his being confused 
about what mode to operate on or that he sounded like he was drunk. The
operator states to QSL via HA5BBE. JA operators are stating that the 
P51AA station is transmitting somewhere in Japan.

S2, BANGLADESH. Erik, WZ6C, has now been issued the callsign S21ZG. This
is valid for one year and he may renew it. He promises to work lots of CW.
QSL to W4FRU.
 
T5, SOMALIA. T5CB is Chuck Brainerd of Tennadyne. He is going to Somalia
the first two weeks of January to install some antennas and train some 
operators. He'll be on the air during this time as T5CB. He says SSB only,
no CW. Plans are for 40, 20, 15, and 10 using a dipole for 40 and one of
Tennadyne's 14-30 MHz log periodics for 20-10. He says he's not sure about
any WARC band operation. Due to his busy schedule, he may only be on 4-5
hours per day. Later in January, another guy (in the military) will be
operating as time permits.
   Meanwhile, TU4EC/T5 was active this week on the 14226 DX net around
2115z. We have no other details on this station.

XW, LAOS. WD4NGB reports that Gus, 9V1ZE, K4SXT/DU3, K4SXT/VS6, etc. 
works for the Embassy in Singapore, and was to be transferred to the
Embassy in Vientiane (Capital of Laos). Gus apparently arrived in Laos
on December 1st, but unrelated matters required his return to Singapore
on December 4th. Gus told Bruce (WD4NGB) that licensing action by the XW
authorities is very slow due to some problems with a previous operation
there by other parties. A 500 watt rig is available for his use. With 
some diplomatic help, he expects to be licensed sometime in early spring.
Evidently, he will not be transferred to Laos, but his job requires some
amount of travel back and forth from Singapore to Laos.

YI, IRAQ. VERON DXPress reports YI1MH is a new station in Iraq. QSN
reports show activity on or around 28507 kHz starting at 1330z. Also,
there has been activity on 14199 kHz around 1515z. QSL via Majid Abdul
Hamid, P.O. Box 5864, Baghdad, Iraq.

PIRATE ALERTS!!
 5X, UGANDA. It has been reported by Baldur (DJ6SI) and Wilfried (DJ5RT)
     that a pirate was using their call sign of  5X5WR on 40 meters SSB
     on December 1st between 2300-0000z and on December 2 on 10 meters
     CW at 0600z.
 PZ, SURINAM. PZ1EE, who is a resident Amateur in Surinam, announced that
     PZ5EL is a pirate. Please DO NOT QSL this station.
     
C9RJJ AND C9RDM CARDS. QSL cards for these two stations should ONLY be
sent direct to Paul, W8GIO, with a S.A.S.E. Paul requests that you should
refrain from using the ARRL Buro. There is already a pile of QSL cards 
for both of these stations at the W8 bureau. Cards sent to the bureau 
will take longer to answer.

Maybe you should find out if he's kidding first before you post such
a blast of someone (and possibly end up with your foot in your own 
mouth, Chuck).
Lighten up, and have fun.  Isn't that what this is all about?

Incidentally, I have been on a DXpedition (Navassa 1988) and I can tell
you that with advanced planning one of the highlights of the DXpedition
was being able to keep short skeds with the families back home.  One of
the greatest thrills in my 28 yrs as a ham was hearing my daughters 
voice on a phone patch from Navassa.  I will also tell you that we 
purposly limited the amount of time that we devoted to such activities.
Those skeds are VERY important.  One of our skeds was with a doctor on
Jamaica, 6Y5EE, and we needed to talk with him urgently when one of 
the guys helping us unload got burned with battery acid.
So, give the DXers a break.  Follow their instructions, and requests, 
and it will work out best for everyone.

The American ops are fantastic.  I remember many times that there 
were huge pileups of mostly Americans, and we'd ask them to QRX while
we listened for Europeans or JA's, and 99% of them would.  Of course
there are exceptions, but they can be dealt with.  One effective technique
is to work them and not write the call in the log ....

To: info-hams@ucsd.edu

How come only DXers are getting blamed for this rude behavior? It seems to me
that most anytime I get on and have a nice long chat with a old friend, in
the U.S., any number of U.S. ops will interrupt the QSO. This is especially
true on 80 and 40 meters. Many people will call in saying "just wanted
to get a report" or "your really loud, just had to call in". They didn't
have anything to add to the conversation. Is it OK to do this to a U.S.
contact and not to a DX contact?

Subject: Has anyone hear of a KR-10?
To: info-hams@ucsd.edu

In a recent posting, Will asked about the KR-10.

KR-10 is really the Kenpro KR-010.  It was a neat outboard
controller that talked to the Kenpro KR-series
az/el rotators.  Kenpro is now marked by Yaesu, but they
don't know anything about the KR-010 (I called 'em).

The KR-010 has 10-bit A/D input and talks RS-232 to the
computer.  They are quick, rugged, and easy to interface
with.  RealTrak, my satellite program, has a driver for the
KR-010 (among others).

The KR-010 is not available any more.  I've only seen one in
my life.  If you can find one at a flea market, grab it.

Yaesu has just introduced a successor to the KR-010, called the
GS-232.  It's also a standalone 10-bit box that talks RS-232.
Its commands are very similar, so it might work in place of the
KR-010.  The GS-232 also has a table-loading facility for off-
line tracking.  Call Mr. Yaesu and inquire.

To: info-hams@ucsd.edu

Hello, netters.

I had been a Korean HAM, and now have a US licence. I want to buy 2m or
440 MHz HT near future. But I will return to Korea in about 2 years .   
So, I want to buy one which I can use in Korea without any problem.
I will appreciate for any information about operating privileges above
6 meters(if possible detailed like 144-148Mhz etc.) or letting me
where I can get such information.

Thanks in advance.

I tried this.  The good news is that it compiled with no problems on a
DecStation 5000/25.  I used the "generic X11" option.  The bad news is
that it has a severe timing problem on Decstations.  I have not looked
at the (computer) code yet to try to figure out why.  Though the
problem changes at different code speeds and some combinations of
actual speed and Farnsworth speed are almost usable, the default
settings cause J (for example) to sound like I T T ;L sounds like I I,
etc.  The problem is obvious to one who knows the code.  I just hope
someone not familiar with the code doesn't think this is the way it's
supposed to sound.  Incidently, the problem appears not to be specific
to the 5000/25's hardware.  A 5000/125, 5000/200 and 5000/240 all give
the same results (and this almost covers the universe of Decstation
5000 machines).  The problem may be trivial, and I intend to look at it
when I can.  If someone else solves the problem, please post.  I am
running Ultrix 4.2b which I think has the X11R3 X libraries and am also
running the development version of the Motif Window Manager.  This may
be the source of the problem.  Someone running Ultrix 4.3 or OSF/1
might try this program and see if the problem goes away.

I've played with power mosfets as RF amps... I was going for
maximum efficiency so I was basically using a square wave to drive them.
I haven't tried driving them with a QRP rig with it's tuned circuit and
sine wave output, so I can't comment on that.

I actually ended up using an ICL7667 fet driver chip to drive an IRF511,
which in turn was driving a bigger fet (an IRF440).  The circuit looks
something like this:

                       +10V                     +40V
			 |                        |
	                +-+                      +-+
			| |                      | | RF choke
                        | | 8 ohms(*)            | |
	+10V	        +-+                      +-+  blocking cap  
          |              |                        |     | |
 ICL7667  |         ||---+-----------+       ||---+-----+ +--->to T output
	  |	    |                |       |          | |      network
	|\|         ||<--+  IRF511   |       ||<--+
	|  \        |    |           |       |    | IRF440
 TTL >--|   >-------||---+           +-------||---+
DRIVE	|  /             |                        |
	|/|             GND                      GND
         GND

    (*) - Pay attention to the power rating on this guy! ;^)

The gate capacitance of the IRF511 is no problem for the ICL7667. I think I
also had a very small resistor (a few ohms) in series with the IRF511
gate to tame things a little.

I had two of these drive circuits (ICL7667-IRF511-IRF440) with the drains of
the IRF440s connected in parallel.  At one point I had about 175 watts 
cranking out of it on the 75 meter band, although efficiency was better at 
lower power levels.  I was using it on AM (with a PDM modulator, but that's 
another story...) and I ended up running it at about 75 watts out with 125% 
positive modulation.  Overall efficiency (including the modulator) was
somewhere around 80-85% if I remember correctly.

I hope this is of some help.

Greetings:

Regarding the Belden catalog, I'd say it's very useful.  There's a lot of
stuff listed besides coax, but the listing for each coax product shows
information like loss in db per 100ft. at several frequencies, etc.  I'm
sure they'd send you one.

As to the tone finder, I didn't buy the one you mentioned but instead
purchased the CD-1 made by Connect Systems, Inc.  It's sitting next to
me now (down, boy).  This little box decodes CTCSS, DTMF and, allegedly,
DCS.  The instructions put me off a bit as they said the audio for the
unit had to be derived from a receiver stage before the de-emphesis circuit -
this after the "guy on the phone" assured me the tape output of a scanner
would do.  Making an internal would be a bummer here as we plan to use
the box on several different radios.  So anyway, as you might expect, I
just attached it to the tape output to see what would happen.  After a
but of judicious tweaking with the internal gain control (in the CD-1),
it reliably decodes CTCSS and DTMF.  For the latter, it repeats what it heard in 
in 4 digit groups after the carrier goes away.  But no joy on DCS so far.
I expect that for that one really must "go inside".

I would like to to experiment with writing some software that would
utilize the HAMCOM type interface.  I am in search of some example 
source code that will accomplish the sampling from the interface.
I have an understanding of whats going on but have never tried
to sample from the port and count timer ticks. (I think this is how
the HAMCOM and similar software works.)

Any pointers would be appreciated.

Has anyone any experience installing a mobile rig in an '86 Toyota
Corolla (or similar clone)?  Specifically:

1.  What is the best way for removing the head liner in order to
    route the antenna coax from the roof?

2.  What is a good route through the firewall for the battery connection?

3.  Does RF interfere with the operation of the car's computer system
    in this vintage model?

4.  Are there any other problems I should be alert for?

     I remember reading in a couple magazines about people who were

	very upset because they just bought their new toyota before
	
       	reading in the manual that you can't operate a two-way radio

	with more than 10 watts output. I don't remember the specific
