A friend of mine from the Army Security Agency had a brother who got in
a car wreak and paralyzed him. Had his neck whiplashed and left him in
a fetal position unable to talk, move, etc. Thanks to my friend knowing
morse code it was found his paralyzed bother could use a code reader to
communicate with his family, friends and others. Was something to see
but still gave me chills. He would use a type of "key" in his mouth and
send morse code with it. Seems his mind was clear, just his body was
gone.

Thank you mister Morse.

This writer is a satisfied user (and registered owner) of CT. Our club uses
at least three different versions of it for Field Day and most other
contests. The version I have (8.14) provides three different CT.exe files
depending on whether you have an 8086, 80286, or 80386 machine. That way
you don't have to be stuck with a slow software package after you upgrade
to a fast new PC.

I just wish that the phone modem download/upgrade service was still
available - after all, I specifically paid for that feature when I bought
the program.

The serial number of my FT-530 is 3M230998.  So it looks like it is from
lot 23.

Do you prefer the Heil 4 or 5 element?

My primary interest in using a mike at all is HF contesting. I would assume
that the 4 would be the ticket, but I have heard the 5 recommended too.

Rig in use at moment is TS940.

Thanks for your help.

I have seen similar capacitors inside

anyone know how big (uFs), these

I tried doing a similar mod for the TM-431A and it didn't work
either....  some guy from finland sent me the proper matrix for that
radio...I haven't performed it yet...looking at the schematic, it seems
that I might be enableing euro repeater offsets instead of the the US 5
mhz offset...

Anyway, check your schematic and find the 431A (non-usa) one and that will
have the diode matrix you need...(I think)(...

To: [e-mail]

I am looking for a case or something I can replace the radio clip on a
htx-202 with that is like the GE radio clips. You know the one that has a
round thing that you slip inside the belt case... Some I belive you have to
turn upside down to get off. I dont know hat these are called, so it it hard
to explain.. But I am sure someone knows what I am talking about. Well I am
wanting to buy one of these. Dont need the belt side, I have that.. Just
some way to attch it to this radio.

                        THANKS!!

The links are on 40 meters during the day and 75 meters at night. Once or
twice a year the boys on 440 will patch three or four private link
systems together for the fun of it. It gets old fast so they turn it off.

Subject: RFI proofing my computer?
To: [e-mail]

Along the lines of proximity and the guy who bought a tower case, give
some thought to getting a side-mount stand.  You can use this to
mount the CPU on the floor with the floppy towards the top.  It
is not inconvient when mounted like this.

Before doing this you obviously should do as suggested and try to
isolate where the problem is coming from.  The case that it is
radiating through the chassis can sometimes be cured by the side-
mount floor stand.

Subject: Vertical Antenna Recommendations?
To: [e-mail]

I personally would recommend the Butternut. I have an HF6V with 12/17 and
160 meters added and am a believer in it. I DON'T believe the claims about
the R7 and others not needing radials and being equivalent to the Butternut.
Right now I am reading a book called Vertical Antenna Handbook by Capt.
Paul H. Lee, USN(RET), N6PL published by CQ magazine. I recommend it to
really get an idea as to how verticals really work. At least, I recommend
it as of chapter 5.

One thing I have noted, any vertical you listed and I have seen advertized
is extremely short and inefficient on 80/160 meters because the feedpoint
resistance is like 1-10 ohms and the reactance is 300-1000 ohms. Hard to
get the antenna current up and to radiate. Check out the book.

Good luck

Subject: Yaesu FT-41R PL problem--read before buying (FT530 note at end)(LONG)
To: [e-mail]

This note is being provided as a service to the amateur
community.  It is not intended to endorse or dis-endorse
this product, but rather to educate the community to a
problem, for which a solution exists.

******************************************************

The Yaesu FT-41R (and perhaps it's sister 11R) has a problem
with the PL (CTCSS for you Motorola lawyers) tone frequencies.
If you do NOT buy the optional FTS-26 CTCSS DEcode (tone
squelch) board, the PL tone is generated by the microprocessor
itself, rather than a dedicated PL tone chip (MX265).  As a
result, the PL tone generated can be slightly off, to a
degree to make certain reed-type decoders used on some repeaters
go nuts.  This makes repeater use difficult, if not impossible.  If you do
go out and buy the optional FTS-26 board, the tones are
generated by the board, and this should not be a problem.

It turns out that the PL tone is too high in pitch, and this difference
is audible at the 250.3 PL.  Yaesu's fix, according to
Yaesu Tech Bulletin 9420 is to increase the size of the
capacitor on the microprocessor crystal to pull the frequency
down, thereby lowering the PL.  The mod specifically calls for
C2018 to be changed from 33 pF to 39 pF.

I have not done this yet, as I am awaiting the part from Yaesu.
This mod is built into the factory beginning with lot #12.
Units prior to this will need to be mod'ed or you may just
be lucky.  To determine your lot number, look at your serial
number.  the lot number is the two digits immediately following
the letter. (i.e. a S/N of 3M078626 would indicate a lot #07)

If you are contemplating buying a unit at a retailer, check the
serial number -- if it is prior to lot #12, test the unit on
a few repeaters and see if your voice drops in and out.
Newer repaters with electronic decode tend not to be as sensitive
to PL frequency mismatch as are old mechanical reed style decoders.

************************************************************

Also, to FT-530 owners:

There is an existing INTERMOD fix for the 530.  Now, before you
all go and jump to put your units in the mail, let me tell you
what this mod does.

The mod entails changing the first IF frequency of both receivers.
The VHF frequency moves from 15.25 to 17.25 MHz, and the UHF
frequency moves from 47.225 to 44.775 MHz.

What this buys you:

  If your INTERMOD problem results from two strong signals that
are mixing in the front end to produce a signal at the frequency
you are trying to receive, this mod will do NOTHING for you.
(e.g. you are listening to 446.00 MHz, and two signals at 452.00
and 458.00 MHz mix to produce a tone at 446.00 MHz, then you are
out of luck).

  However, if the problem results from two strong signal
that are mixing to produce the IF frequency, then this may help.

  Alternatively, if the problem is really IMAGE response
(you are picking up a station that is 2xIF away from your desired
station), then this MOD will help.

Think carefully and investigate thoroughly what your problem really
is before you send the unit in.  The mod does nothing to affect
receive range, nor does it do anything to change RF desense,
overload or other nastiness, just changes the image response
frequency...

A hint in diagnosing your problem... The first IF frequency is
not dependent on the frequency tuned, but rather which receiver is
used.  The left receiver uses the VHF IF, while the right receiver uses
the UHF IF.  Tuning a UHF frequency in the VHF side uses the VHF IF,
and vice versa.
