Walt, where did you or those you allude to get the notion that someone HAS
to talk to you on the amateur bands? There's no requirement that someone
MUST answer your CQ on the low bands either. Amateur radio operation is a
privelege granted to those who meet technical requirements, but
conversation is not a granted right that accompanies a license. I am
certainly allowed to ignore someone calling on 2M just as I can ignore the
dog barking next door.

Open repeaters weren't the original issue in the thread (which is still
running in r.r.a.policy, by the way). The issue was the refusal of a
coordinating committee to allow more than one repeater per channel, despite
the FCC requirement for channel sharing and non-exclusive use of any given
frequency.
IMHO the problem is MORE severe in the 2M band than at 440, although the
ridiculously high number of linked machines which simultaneously broadcast
the same information on 6, 2, 220, 440, and 1296 compund the problem in all
bands.

Roger, from your callsign I can see that you hold a high enough class of
license to know that you can either personally fill some of that
underutilized spectrum with your own repeater, or join one of the smaller
special interest groups that utilize 440 for their amateur radio
activities. Open repeaters weren't the issue, access to spectrum was and
continues to be the problem.

Bob,
IF you can, find the manual, it is essential to programming the th78.
If you have really lost it as opposed to misplaces, i may be able to
send you a photocopy.

The thickness and durability of the fiberglass radome is a major
consideration, and since these are hand-built it controls the antenna price
much more than the price of the copper inside does. After a winter on a New
England mountaintop, you begin to see why the Diamond sells for less. Also
remember that Diamond and most other imported antennas have gain ratings in
dBi, which is 2.1 db more than the dBd rating!

First things first. Celwave purchased the old antenna manufacturing portion
from Phelps-Dodge Copper Co. several years ago. Celwave itself is a
division of Radio Frequency Systems. So when people talk about Phelps-Dodge
antennas today, they really are refering to Celwave RFS. Celwave owns the
trademarks "Stationmaster" and "Super Stationmaster" among many others.

Next, call Celwave at 1-800-321-4700 to obtain their current "Product
Selection Guide #191" catalog. The local distributor also should be able to
give you one to inspire you to do business with him! Most of the
information you need is in there, but I'll summarize it here for all to
read.

Last, the people who advised you are correct, but not for the reason you
think. Read on for details, and you'll see why a brand-new PD220 is the
best way to go,
followed by a used PD220 in the 151 to 159 ranges.

The PD220 is the Super Stationmaster, a rugged implementation of their
patented colinear dipole design. It is rated at 4.8 dBd in the 2M band,
overall length 22 feet; the support pipe at the bottom is 2-3/4" OD and
about 30" long in the ham band model. The ranges are suffixed as follows:
  PD220-1  136 to 144         PD220-2  144 to 148     PD220-3  150.5 to
158.5
  PD220-4  151.5 to 159.5     PD220-5  155 to 163     PD220-6  162 to 170
  PD220-7  166 to 174         PD220-8  216 to 225

> We've contacted a local distributor regarding the purchase of a new antenna.
> Cell Wave PD-200.  Big bucks.  Distributor says this antenna is 21 feet long.
> I'm also not sure I've got the model prefix correct.

The PD200 is the regular Stationmaster, a lighter duty version rated at 5.8
dBd. The element housing length is 19 feet, the antenna is only 1.13 sq ft
wind area, and the support pipe is smaller (2-3/8" OD) and shorter (22").
It was NOT designed for wide bandwidth, only 1.5 MHz at 1.5 VSWR, so you
specify the center frequency when ordering and you can't reuse them in a
different part of the commercial spectrum or amateur band. They all show
the same number PD200 on the tag.

Ignore the lengths and go strictly by the model numbers when you can. It's
what is inside the radome that matters, not the dimensions of the
fiberglass housing. The most important thing is the model tag, because it
tells you two important things: What frequency range the antenna was built
on, and what frequency it was tested on.

In your case the statement that the antenna is 20 feet long means that it
is PROBABLY the PD200, which is incapable of operating efficiently on 2M
when built for 152.x MHz. You can verify my educated guess by checking the
OD of the radome at the end where it joins the metal support pipe.

Don't try to disassemble it and lengthen the elements; you'll damage it
beyond repair and you never get the radome watertight again! There is no
external tuning adjustment; these are custom-built and custom-tuned
professional grade antennas. Instead, take advantage of one of the unique
advantages of an end-fed broadband colinear: the ability to get a slight (3
to 4 degree) downtilt of the main lobe if you drive the antenna at about 5%
below its cut frequency. Thus if you put 146 MHz into a 152 MHz PD220
antenna, the VSWR will only be about 1.9 and the main lobe comes down from
horizontal by about 3-4 degrees so you aren't shooting so many precious
ERP-watts (new term, Gary?) into the solar system. You can't do this with
the PD200 because its "Q" is too high.

Gary, I owed you one so I thought I would pay off early before the interest
rates went up again! Feel free also to add or modify from your experience.

The first rule in rfi is to attack the SOURCE of the interference, rather
than try to prevent it from reaching it's destination.

I had an older suburban with the same problem.  WhT i HAD To do was to put
both resistor ignition wire AND resistor plugs.  Suburbans have very High
Voltage (HT) ignition systems.  I also had to heavily filter the 12 volt
supply line.  (Some power was lost with the resistor wire/plugs)

david-

The function buttons are "multiplexed", sharing the microphone's up, down
and push-to-talk button lines.  I don't have the exact data at hand.

I sometimes have trouble with functions being activated while using the
up/down buttons.  When function 1 gets activated, I can't procede with the
up/down function until I manually press button 1.  Does anyone else have
this problem?

I use a small Macintosh application called MacShortwave which will not
only do what you ask but will also show MUF and LUF on all ham bands by
time and path.

You can program 50 location buttons by name and lat/long. Then, when you
select two city pairs (yours and another), it will tell you the distance
in miles and the best frequency for the time of day. You also need to put
in the current sunspot number.

But, this is for the Mac . . . there must be something similar for DOS if
that is your environment.

     You can "use" any spacing you want for casual transmissions, as there
is no "official" FCC rule on this; for example, a lot of locals in
my area use 146.535 for simplex mobile.  However, you may get flack
from some operators for not adhering to the ARRL Band Plan (which
specifies precise simplex frequencies between 146-147 and 147-148 MHz).

     If you use FM during a VHF contest, use ONLY the ARRL-specified
simplex frequencies as called out in the Band Plan (they're listed in
the ARRL Repeater Directory) EXCEPT (a) you CANNOT use 146.52, and
(b) you CAN use other simplex frequencies as locally APPROVED by
the frequency coordinator(s) in your area.  Note that I said
approved, NOT "agreed upon by an ad hoc group of local hams."

Strange thunderstorm. Generally the problem is the abundance of wind.

They did cost money at one time. Virtually every other country in the

Since you brought it up here's an update:  The university, due to a flood
of complaints from students, faculty, staff, and the student newspaper,
have taken the drastic action of removing the doors from the stalls in
all the restrooms. No privacy but at least the gays have to go elsewhere
to do what ever it is they do to each other.  No more sticky floors.

It's easy to tell that you haven't been on a college campus for a loooong
time. Funny that you've been thinking about this all this time, though...
