The paging function uses standard DTMF ... if your repeater passes or can
be programmed to temporarily pass DTMF then you could page through the
repeater. A typical message could be sent to a TH28, TH48 or TH78 like
this...

Message =  CALLME

DTMF    =  # 2 C 2 A 5 C 5 C 6 A 3 B #

There are 10 receive message memories of 6 characters each, so you could 
send up to a 60 character message. The units also have 10 transmit 
message memories of 6 characters each.

Subject: Re: FT-470 intermod fix ... Can you tell?
Organization: Hewlett Packard Company, Spokane, Wa.
Newsgroups: rec.radio.amateur.misc

Another way to tell is to hook up a spectrum analyzer to the antenna
input (Be careful not to transmit!!!) and look at the first LO leakage.
It is very easy to see on my radio (about -50 dBm).  The first LO will be
offset from the receive frequency by the first IF frequency.  At 144 MHz
the LO will be at 165.7 MHz.  For receive frequencies above 157 MHz, low
side injection is used. 

You are correct that the new IF frequency is 21.7 MHz, however I had the
Yaesu technical guru tell me it was 21.15 MHz this moring.  It turns out
that the part number for the new part is 21R15AU and he got confused.  The
changes done in the modification are as follows:

RF Unit:  XF2001  was 17N15AU and is now 21R15AU 
          XF2002  was 45N15A1 and is now 47M15AU
	  L2007  was 4.7uH and is now 3.3uH
	  L2008  was 4.7uH and is now 3.3uH

IF Unit:  X3001  was 16.845MHz and is now 21.245MHz
	  X3002  was 44.615MHz and is now 47.265MHz

The service manual does not show these changes. 

By the way,  I don't think the IF change did anything to the intermod 
performance of the radio.  A friend has an unmodified radio and it checks
out exactly the same as mine.  The problem here may be terminology.  The 
front end intermod performance is primarily determined by the mixer and
the LNA.  Intermodulation produces a signal at the desired receive frequency
which will be converted into the IF no matter what the IF frequency is.
I suspect the actual reason for the change was to move a spurious receiver
response out of a commonly used public service frequency band.

After a few weeks of experience, I have found that all of my favorite 
repeater frequencies have intermods or spurs of one order or another that
will break the squelch even when I am using the rubber duck antenna (really
bad on a quarter wave ground plane).  I hope this will be fixed in their 
next dual band offering, but I am sure I won't be buying one...  This has
not been an enjoyable experience.

A friend of mine has one and loves it; he just goes on and on about what a 
great 
antenna it is.  My understanding is that not only does it not need ground 
radials,
being a half-wave antenna, it actually works better without them.  The 
idea is
to get it up as high as possible, to take advantage of the very low angle 
of 
radiation.  The thingies that look like little radials are, I am told, in 
fact
de-couplers to isolate the antenna from ground.  Everyone I've talked to
who uses this antenna likes it.  I've used on of field day over the years, 
and
have no complaints.  It's a bit pricey, but it sure seems to be a nice 
antenna.
Good luck...

Two days ago I passed my Extra tests, so my study techniques do work, at least 
for me.  For the element 4B test (Amateur Extra written) I used the study cards
sold by VIS (from Mississippi.)  Their package consists of double-sided cards.
One side has the question and the multiple choices, the other side has the 
question and just the right answer (and perhaps some  very brief explanation 
of it.)  I believe there is a card for each question in the exam question pool.

Advantages of this system:
   1.  You can segregate the cards into piles, such as "Already know this", 
    "Need some review" or "Virgin Territory".
   2.  Easy to study for just a few minutes at a time, anywhere.
   3.  No extraneous material.
   4.  A quick and easy way to pass the exam!

Disadvantages:
   5.  There is much repetition of single concepts; rephrased, or with different
    numbers to plug in to the proper algorithm.
   6.  The explantion is missing on some cards where it would be easier to
     learn the formula.  
   7.  The system is designed for you to memorize the correct answers, perhaps
     with little or no understanding of theory or application of that info.
   
IMHO, this final point is potentially harmful.  You could pass the test by
rote memorization, even those question involving calculations.  

BTW, I found the Extra test to be much easier than the Advanced test was, nine
years ago.  (I've been licensed for 27 years.)   On the CW side, I used the
Morseman Plus program on my PC, W1AW's practice sessions, and a few QSOs to get
up to 20 wpm.  I think the PC-based practice was most important.

Using a hole punch is not a good idea as it tends to warp the metal

C528 or the later model (I forget the number) a look.

FYI... if you're into covering the ENTIRE ham band, my C628A does
quite nicely from 420-450 MHz.  Quite a nice piece of gear for working

I own a TH-77A and previously the TH-75A. The technique to figure out what is
the PL code in use is to turn on the CTSS on the HT and then select PL tones
until you break squelch. I used this to figure out what PL the security guards
were using during a recent emergency drill at work. Of course, this may be
beyond some HAMs now, (insert the license class, age group or other category
of your choice here) so that feature is a nice one.

        Did you mean factory NEW when you said "new" or just new to you? 
There is a free factory upgrade for the FT-470 that applies to models from
certain lot numbers.  I believe the most predominant one is lot #19 and
lower have terrible intermod problems.  Mods are made (supposedly) to IF
stages etc... and sensitivity as well as selectivity are increased after
the mod.  There may be other lots that have problems as well (I know lot
#30 has quite a number of problems ie. batt saver not functioning
correctly, low output power, mushy squelch etc...).  The lot number is
usually the first two digits of the serial number if I remember correctly.

        I would suggest calling Yaesu at (800)255-9237.  They will probably
be most helpful and will tell you if there are any upgrade mods since you
bought your radio.

In addition to having all of the "I"'s dotted and all of the "T"'s crossed,

I suppose it depends on your sense of aethetics; myself, I find it hard to
consider a design that doesn't work "elegant"...  If "reliable" appears on
the spec sheets, relays may well be "elegant" where dozens of EMI suppression
components that won't protect the CMOS circuitry anyway would be just a

I run a G5RV up about 35 feet in the middle. It loads up fine on 80,40,20,15

are usually 4x or 53 and don't do as well in the pileups as I'ld like.  I'm
thinking of building a dual quad just for 20m but can't complain as I've got
quite a few countries with the G5RV with a barebones FT-101Z and have 
good success on every band except 160m.

By the way, I do have a balun on mine, and use a tuner;  I understand that
I need neither of these with this rig and antenna (tube finals) but love to
see that SWR drop.  It gets below 1.3 on every band except 160m.

If the factory mod fix requires a change in the IF frequency,
a couple turns of wire and a general coverage receiver should
be enough to verify the frequency change.

Wrap the HT with about 10 turns of insulated wire around the
case.  Connect this to a piece of coax connected to the receiver.
With the HT on, enough signal should leak out to be detected
as a tone in the SSB position.  Tune to the old and new IF
frequencies, and listen.  You will hear the osc. singing !!!!

A freq counter lacks sensitivity, but a GC receiver with -120dBm
MDS, works just fine. The S-meter reading may be only
S1 or S2, so do not be alarmed.  A shielded osc is not very
strong.  This may be of some help.

So, keep the case on, close your eyes, and use your ears.

.  This would give them the same status as landline phones
in terms of getting permission to 'tap' them and use them as evidence, but
only as far as police are concerned.


As far tas the morality of listening to these calls goes, that's something
that you'll have to decide for yourself.  But, remember that these
people are transmitting their calls to the world everytime they 
pick up the phone.  If they are unaware of this, it is due to their
own neglegence/stupidty.
