Hi, 

I've been using quagi antennas on 2 meters and 435 mhz for the past couple of
years for Oscar portable setups and ATV and other quick and dirty lashups and
have found them to work well and be pretty easy to build and match. But I am
not sure I am getting all I could out of them. I've been using the dimensions
from the handbook, and interpolating to get up or down to the frequencies of
interest (for example, the handbook has a design for I think 446 Mhz, and I've
needed 439.25 and 435 - and now I need 421.25 mhz). While the interpolation
seems to work, I wonder if anyone has the actual design information on these
critters? Do any of the programs that model antennas handle quagis? The 
director spacing in particular seems to be a little weird when I compare it
to a straight yagi, sort of a gap between a couple of the elements that I 
don't know the reason for. I've looked up the original articles QST by 
Overbeck, and he doesn't give any design information, but does allude that 
the spacings were determined empirically if I recall. 

My project is to design a simple gain antenna for our local club for people
who want to watch the output of our ATV repeater. My plan was a 6-8 foot
boom quagi on a 1 by 2 (has worked well for me in the past) with a preamp
up at the antenna. While we are at it, anybody got any recommendation on 
cheap 420-440 preamps with better noise figures than the 5 db the RS units
have?

Thanks for the help.

I am in the process of building a weather satellite decoder board and I'm
looking for a suitable receiver (preferably used). The satellites I'm
interested in transmit in the 137MHz range. It seems one of the most
important aspects of a potential receiver is a failry wide IF bandwidth
of 40KHz.

I've not been able to locate a receiver/scanner/etc that has such a wide
IF bandwith.

Any pointers are welcome.

Perhaps the best way is to get a noise bridge or antenna analyser (like
the MFJ stuff) and experiment! See what difference it makes. If your

us know what you find (write it up for a journal).

Or try a couple of Slinkys

BTW -- look at the radiation patterns in low band DXing for a low

folded T (they're all in there). Try to get something with some
vertical radiator.

Above 7100 is only an amateur band in region 2 (North and South America) as
you realized, the upper end of 40 M gets pretty crowded with broadcast stations
from Europe after the sun goes down (and the tide goes out...), but it's still
possible to operate in the spaces.

[Excellent Third Party Question Deleted, due to limp mail service here :)]

Situation:
Technician class amateur radio operating [Key Word Follows] *OUTSIDE*
the technician bands under the control of and within the privileges of
another ham with a higher class of license.

Analysis:
Anyone operating outside their license privileges is an unlicensed operator,
and a control operator is required.  If a control operator is required, then
there are three parties to the QSO: The local operator (who is talking), the
distant operator (who is also talking), and the control operator (who is
responsible for the transmitter).  That makes three, and this QSO is legal
only with a distant station located in those entities that allow third-party
traffic.

Conclusion:
The Technician's license doesn't mean a thing if the VFO is set outside
the technician bands.

Jeff:

Boy, from the responses to your question it seems we are lost in a
semantic jungle.  "Linear loading" seems to mean different things to
different people.

My impression of the best type of linear loading is lengths of wire
or rod tacked on the end of as long a length of straight run as possible
in your situation.  As was pointed out by previous posters, most of
the radiation comes from the 1/3 of the antenna closest to the center.
Make that as long as possible, then add enough extra length (preferably
at right angles to the main wire) to reach resonance.  Actually what
you are doing is adding capacitance on the ends, so you can run several
wires/rods in different directions (like a "top hat") if that is more
convenient.

The best reference for this kind of "shortening" is in Les Moxon's work
which has appeared in various publications for the last 50 years!  See
his HF ANTENNAS FOR ALL LOCATIONS, published by the RSGB and currently
available from ARRL and most ham dealers.  It is one of the best general
antenna references available and is a good investment for any ham.

Summary: I've built K2PH's simple interface.


I happen to be one of the two Amateurs that have built K2PH's interface for 
the Kenwood TS-940. It is simple ( a couple of 5.1 V zeners from RS) and it
works.  I understand the standards purists might object to this implementation.
I've spent a good portion of my professional career working on standards and,
more importantly, implementing standards.  (Actually they're more appropriatly
called "Recommendations" that happen to be made by standards organizations,
but that's another story.)  I fully recognize the pitfalls of taking shortcuts
when implementing a standard interface.  However, I've found that anytime you 
build an  interface, you have to consider the application for that interface.
That will determine how sophisticated that interface should be.  I suspect
that, for most Amateurs, the simplest RS-232/TTL will suffice and only a 
small number will EVER require an interface that adheres to the standards.
When and if that time occurs for me, I'll build a more elaborate interface.
Until then, the two RS diodes (2 for $.59) soldered in my DB-25 hood are 
smaller, simpler, cheaperand less prone to failure than  any of the other
interface ciruits I've seen.  (Besides, it requires no power supply!)

I agree with Wally that optoisolators would add a level of protection to
the equipment being interfaced.  I didn't happen to have any laying around
when I was experimenting with this circuit.  Again, sometimes you have to make
a judgement call.  I decided that, in my case, the worst thing that could 
happen is I could lose the $1.29 receiver chip on my PC I/O card or the $.49
hex inverter  chip in my TS-940 and it wasn't worth the time and effort to 
go out and get  optoisolators that probably weren't needed.  I appologize for 
the "mediocrity" of this design.  I've already used it extensively for 
for three contests and it's working just fine.

Haven't tried phone in that narrow of a band, but I have run AMTOR using 
a 270 Hz CW filter.  As for thruput, we have:
.45 sec/3 char burst = 400 char/min.  400/5 char/word = 80 wpm.

80 wpm, error free, in a channel not much wider than that used by a CW 
QSO.

I better quit, because this is starting to sound like a reason to get rid 
of all code because the infomation density is too low... and I haven't 
started on the newer modes that are even higher density...

Transverters have become as scarce as hen's teeth. The Microwave Modules
MMT series is out of production, apparently MM is out of business. Kenwood

but I've heard they've discontinued it. Check the fleamarkets at hamfests
for these units. SSB Electronics of Germany makes a fine line of transverters,
but they are very expensive here. There's a kit from Down East Microwave that
you can build, or you can roll your own from designs in the ARRL Handbook.

So true, Mickey Mouse (as we used to call them in the UK!) were pretty 
good -- even made in Liverpool my home town!

Beware of the older transvertors though -- they often have a much worse 
NF and DR compared to modern units.

The SSB Electronics are the Mercedes of the world -- with a price to 
match. The ARRL designs are excellent (GaAsFET amp followed by a 17dBm 
drive diode mixer will give decent DR (limited by your 10m RX) and a 
0.6dB noise figure: good enough for anything).

Finally, Hamtronics (see their ads in the Ham press) make 10m to 
50/144/222/432/435 MHz RX converters and 10m to 144/222/432/435 1W

Anybody out there using these or their helical reasonator preamps? I'd

   Hams who drill holes use 1/4 wave 2M antennas when they know the
commute will "destinate" in a parking garage.  For other trips,
especially on the open road when the distance between repeaters is
likely to be greater, they will unscrew the 1/4 and install a 5/8.
This is a major advantage of a permanently installed antenna.  Every time
you remove and then reinstall a mag mount, you will scratch your paint just
a little bit.  Over the years, if you always replace the mag mount at the same
spot, you will leave a blemish on your roof.  In comparison,
there's no wear-and-tear on the car when you change antennas with a
permanent mount.
