As a person that is just getting started building his own equipment
I have seen designs on how to build your own SSB transmitters that
don't take all that many parts and have circuit boards available for
them. Though interesting enough CW transmitters/receivers are easy to 
build. However, like CW they take some effort and there fore not many
people build them. 8-)

So - does anyone have, or know where I can get, a

I have the Antenna Specialists 2m only glass mount, which may very well be the
number you cite.  I found it pretty easy to install, and out of the box it had
a SWR of about 1.5:1, I couldn't really tune it much better.  As far as
coverage, I frequently find that I can (for example) hit repeaters better than
I can hear them (if they are far away).  I have compared it to a 1/4 wave mag
mount and they seem real close in performance.  I guess I would recommend it.

I am getting ready to put up a 500 foot beverage antenna, and have a 
question about the matching transformer used.  Several articles mention
the use of a low permeability (mu) ferrite or iron core, but a couple of
local gurus use a high permeability (1000 - 5000) type.  The articles
mention T200-2 or FT243-63.
Does anyone out there have any empirical data to back up either idea?
I felt that a high mu core was better to get better coupling between the
turns, but I am concerned about losses at the frequency of operation.
Thanks in advance for your assistance.

Nothing will protect you from a direct strike; if your

real purpose of a lightning arrestor is to bleed off static
charges from near-strikes before they reach dangerous
levels.  The good ones (i.e., expensive) work a lot better

Subject: Building Receivers
Date: 5 Nov 92 20:39:15 GMT
Organization: Aurora Technologies, Inc.; Cambridge, Mass.

I have recently read several postings concerning the construction of simple
receivers. While these seemed to grow out of another subject, I thought that
the following would be of interest to those who might like to build a high
performance, yet simple, compact and low cost receiver. Block diagram follows.

 L/C Band---NE602 Mixer---Cohn Xtal---MC1350---NE602 Prod.Det.---LM386 AF Amp.
 Pass Fil.       |          Filter    IF Amp.         |  
                VFO                                  BFO

While this is a traditional single converstaion superhet design, it uses only 4
IC's. I've built over 15 of these receivers (or in a transceiver) over the last

The IC's use very few external parts. The NE602 is a double balanced mixer with
internal biasing and on board oscillator/buffer. The MC1350 is a high gain wide
band amp with agc conrol. The LM386 is a well know part.

The crystal filter uses cheap micro processor crystals. It is a ladder network
with capacitor coupling. They are very easy to build. Band width can be changed
by changing the C value to cover CW/SSB. Make the filter with 12MHz crystals
and a 5MHz VFO = 40M (a 16MHz Fil and 5 MHz Vfo = 15M, 10MHz Fil and 4 Mhz VFO
= 20M etc,).

One example of a design can be seen in Ham Radio Magazine in an article call-
ed Micro-20 receiver (3 or so years ago). A PC board is available from FAR 
Circuits (about $5) and its about 1 1/2" x 3".

The question pool for each element is reviewed and revised

If one had a perfect coils and capacitors, tuned circuits would
be infinitely sharp (narrow).  They're not.  Tuned circuits have
bandwidths.  The simplest way to picture Q is as the ratio of
the frequency of a tuned circuit to its bandwidth.  The narrower
the bw, the higher the Q.  A tuned circuit resonent at 2 meters
(146 Mhz) with a Q of 100 would have a (3db) bandwidth of 1.46
Mhz.  This is the same as the (loss) resistance to reactance
mentioned by the previous poster, without the big words.  In
general, one worries about Q being too low more often than being
too high.  You can reduce the Q of a tuned circuit by placing a
resistor in parallel or in series with it (depending on whether
the tuned circuit is parallel or series), or by building it from
more lossey components.  Unfortunately, there's no equivalently
simple way to increase Q with passive components.

Nor should we lose sight of the fact that the "no-code" Tech Licence
gives full CW operating rights in the VHF/UHF bands, thus granting
adequate access to most satellite modes...w/o a CW test requirement.

BTW, does the 5 wpm test expand these capabilities to any additional modes?

browsing through a MFJ catalog and noticed two separate tuners. There is a
"random wire tuner" (MFJ-16010) advertised for use while transmitting on a
random wire antenna and a "preselector/tuner" (MFJ-956) used for listening
to shortwave broadcasts. What is the difference between the random wire
tuner and the preselector tuner? All comments will be appreciated and
thanks in advance.
