I wonder if Scott, Andy or someone else can tell me what the bias

it has an active microphone element and will work okay if I 
provide a small amount of bias current.  What I want to know is
just how much current is the "right" amount.  Also... I presume 
that I can use a "suitable" dc blocking capacitor and run the

Kansas ham plates do the opposite (that is, they delete something
found on the normal plates).  Normal Kansas plates have a two letter
county designator on the plate.  Kansas ham plates do not have the
county designator and are thus a "state issued" plate.

As yet, I have not found anything beneficial to having a "state
issued" plate.

RG-8 has loss of .9 dB per 100 feet at 20 MHz.  350 feet would give a

50W heat, and 50W to the antenna.   de N6MZ

The UHF side of the TH-78 can be switched to the VHF frequency range and
vice versa.  With this feature you can receive two frequencies on the
same band at the same time.  The TH78 is said to be the only HT around
that can do this.  There is also a memory extension module available
that gives you a total of 250 memories.

Actualy I beg to differe.  There was a very public trial of a drug runner
here in Florida where the Defendant (read as Convict now) claimed that
the Feds had illeagaly tapped his cellular phone.  The courts not only slammed
him so hard his cellular may pass in another year or so, but has condoned the
Southern Bell Mobility activity of recording ALL cell conversations for use
by law enforcement types need them.  The basis for the rooling being that
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".

Another solution is to change the length of the open wire feeder.  It
won't change the VSWR on the feeder, but will change the impedance
the tuner has to match to.  With luck, you will hit an impedance range
the tuner can tune more easily.

It is worth noting that police departments tend to need a small amount of
obfuscation in their radio communications.  Hence, for a police department,
pro-"words" like QLF and 10-666 are more useful than pro-words like "Standby"
and "Roger", so long as their number is not so great that they can't be
memorized easily and used without confusion.  

Q-signals don't cause (much) obfuscation on amateur voice, because most hams
knew them at one point, and can easily pick up the common ones if they didn't
learn them or if they forgot.  However, they are rarely shorter than the
actual words they replace when *spoken*, so there's little point to using
them (and as I've pointed out, if your listener can't hear the difference
between QRM and QRN if either one is present, why not just use "interference"
or "noise"?).

Try the ARRL Antenna Book.  It has a semilog graph of Frequency Vs
Attenuation in db/100 ft for a variety of common and not so common
feedlines including coax, open wire and hard-lines.

I do not remember the attenuation at 20MHz, but at 7MHz it is about
0.8db per 100 feet for the foam dielectric RG8 cable and about 1.6db/100ft
for RG58 cable.  Further, the graphs seemed to be, more or less, straight 
lines and so log-linear interpolation for other frequencies should work 
well.

With all the bad press some manufacturers are getting in this newsgroup,
I thought I would take the time to post a positive experience I had with
Yaesu.  A while back, I lost the little rubber dust cover that fits over
a microswitch on the back of my 727 HT.  So, last week I called Yaesu
and described the part and asked if I could buy a replacement.  The guy
who took my call said, yes, they had the piece in stock and would send me
one.  I asked how much it cost and also if there was a minimum dollar
amount on such an order.  He told me that the part cost less than a dollar
and it wouldn't be worth writing up a bill for.  It arrived today.

I realize this was a small kindness, but it sure made my day, and it's
something I'm going to remember when it comes time to retire the 727
and move on to the latest generation HT.

Yes.  Many people do this, but I don't clean my refrigerator often enough.
Note that Julian said "refrigerator."  This does not mean that cold is good

  It is and it doesn't convert that easily. The MAJOR problem is the screen
  cursor placement commands. NEC has reversed the X,Y coordinates at the
  command level. (Makes sense in a way when you realise how chicken scratch is
  organized) Also, the syntax on several of the commands are just different
  enough to cause non-operation.

  I hand entered the entire program in the CT-17 manual. I started to debug the
  thing and gave up after several evenings. I did write a few routines for
  controlling the IC-761 after I figured out what the radio wants to hear and
  what it sends back.

It is probably the BEST kept secret, and not intentionally so...

Use 52 and the Star touch tone to activate the radio in the Westford Police

2. Disabled cars.... everywhere.
3. Crashes, etc.
4. Fires.
