Does anyone out there in Greater Netland have any experiences with 900
MHz amplifiers? I am looking for one to boost 5 or 10 mW of video up to
about a watt.

Light weight is an important factor...which is why I hesitate to get
DownEast!s 10 mW -> 10 watt amp...it is gonna take some heavy batteries.

Any suggestions for someone with AF & HF kit experience, but little
knowledge of 900 MHz construction techniques and no UHF test equipment?

Some years ago I cut and article out of one
of the Ham magazines on Coaxial Dipole 
construction. I don't remember what magazine,
and I don't even know what year, but I wish
to build one of these antennas for 28.4 mHz,
and I have no idea what dimensions the 
coaxial section should be as opposed to the
wire ends. The antenna looked something like
this when completed:


  Wire       Coax            Coax         Wire
-----------===============X=============----------

X = Feedpoint with RG-8 Coax.

The part where the wire attached to the coax, the
coax center conductor and braid were shorted together
and connected to the wire.


Anyway, I could use formulas or actual dimensions
gathered from articles on such an antenna. Or maybe
there are users of this antenna whom are familiar
with its construction.


I think this antenna might have been called a 
Double Bazooka also, but maybe not.

Any help appreciated

A new filter circuit called the "Bowtie Filter" will soon
be available for the PK232.  It improves filter response and
provides maximum mark/space seperation.  

It also improves the "crossed footballs" on a tunning oscilloscope 
by displaying a + or bowtie pattern.  By using the tuning scope 
and a bowtie you can tune you radio within a couple of hertz of 
a packet center frequency.  The filter can also copy shifts as 
low as 30 Hz and still maintain the (+) bowtie display.  

I saw a prototype that was installed in an Infotech M8000 and
the o-scope display was impressive.  I was able to tune the receiver
on a dead carrier and watch the o-scope display go from | to /
to - in 10 Hz steps.   


The filter boards will be available from Willco Electronics

I've noticed that McDonalds are usually keyed up just about
continuously on 154.71.  It'd be really irritating to be a next
door neighbor to them!  Thank goodness they are QRPP.  I'm not sure
exactly how those frequencies are coordinated.  When we were
working on getting permission to install a UHF repeater on our
microwave tower at work, we had to deal with a person attached to
our state turnpike commission.  I don't work for that department,
so I don't know the exact process.   So far, we're still waiting
for a frequency allocation.  Our maint. people have a low power
repeater on 464.7875/469.7875 that covers basically just the
property on which our building sits.  It'd be nice for us to be
able to talk to our couriers from the tower.  For now, we lease
time on a commercial tower nearby for the courier mobiles; it is
cheaper than cellular-- the ower leases time to many users on the
same channel with assorted PL tones.

Our amateur repeater has an input on 146.295 on top of the tower at
313 feet, so it is nice not to have to compete with another uhf/vhf
system for now.

My wife and I use some regency UHF synthesized mobile rigs in our cars.

I had no trouble at all retuning them for use in the 440 repeater band.

the sensitvity is a little less than a "real" ham rig, but they do 
meet regency specs. ( .5uV for 10 db sinad ). they do have a 20 
watt power output, 10 channels, and work just like they disigned to work.

I was just wondering how one would find out what PL tone a particular radio  
setup was using.  I have noticed that the local McDonald's drive thru window  
radios do not suffer from intermod like mine does on the same frequency as I go  
through their drive thru.  I am assuming they are using some sort of PL tone or  
CTCSS ( not really sure what the difference is ).  I was wondering how you  
might figure out what frequency the PL tone is?

Subject: Three Minute Morse

I have been glad to see Alan's posts about this binary tree of
morse.  I thought up the idea of the tree (minus the mnemonics)
about a year ago when I was first trying to learn the code.
What I needed was something of a PATTERN to make sense of it all.
Well, I got sidetracked and am now getting back into it because
of this handy scheme to learn to associate WHICH LETTER goes
with WHICH SOUND.  That is the hard part.  I think I could learn
20 wpm as easily as 5 wpm.  Here's what I am attempting and suggest
as a pattern:

  - listen to CW of other hams, intently trying to hear the
     letters and the words as distinct units;
  - then, try to start interpreting the sounds;
  - keep practicing to speed this up.

You know you're getting somewhere when you say "That was a 'C',
no wait, a 'Y'...woops I missed a couple letters."  Eventually,
the recognition of characters ought to come faster.  Then, the
recognition of words.  Oh, what a day that will be!

PS, I am indeed one of those hopeless "no-coders" and look at
me...learning morse code.  Breaking all the stereotypes.  :-)
I think CW is pretty cool.  I can make out a lot more CW on
the bands than SSB.  And I think CW would make a darn slick
interface for a full-blown computer watch...I could take notes
during meetings without any distractions or lugging something
around.

For those still reading:  I want to find out about this LOWFER
stuff around 150 KHz (?).  Anyone within radio reception of
Binghamton/Elmira have a regular sked that I could eavesdrop on?
Where could I get a kit or the like?

I have a 736R and love it.

I use it mainly for FM and SSB. I haven't used it on the Sats yet.
I have the antennas on order to do this though.
It has a great receive and the transmit sounds great (so I am told).
It seems to get better reviews than the Kenwood.
There are many functions that take some time to learn and a lot
that are set and forget.
The DOCS are pretty easy to understand.
I plan on getting the 6 meter module. I currently have the 70cm and 2mtr 
modules only.

I have only seen the 9600 baud mods. No mods for freq extension that I know of 
but what purpose would it serve? There are commercial rigs that operate on the 
OTHER freqs that I need.

Thats about all I can say. It does what it is supposed to and does it WELL.

As Jon hints, this is very similar to a double-conversion analog receiver: 
To avoid dynamic range problems, you have to be very careful about the 
gain distribution in front of the high-selectivity filter (at the second IF).  
With a DSP, you would have to design in enough "headroom" (dynamic range) 
so the DSP's A/D wouldn't overload even with signals considerably above 
the in-passband signal that controls the AGC level.

Putting the DSP after the AGC detector is little better than using an
audio filter.  Assuming the analog IF filter has good unwanted-sideband
rejection, you might as well do the DSP processing after the product
detector (at audio).
