yes, AC9N (cmeehan@crems.cr.rockwell.com) and I (wenewkir@crems.cr.rockwell.com) have done a set.  but we were looking at it as a voice radio...they've gotten
some use around hamfests - we put 'em on 52.525 MHz.

the mod instructions we had were from a past issue of Ham Radio Magazine and 
delt with the single channel Radio Shack 49 MHz unit.

i think it cost more in crystals than it did in radios...8-).

I have a high brighness "jumbo blinking LED" which I bought at a Radio Shack
last year (cat no. 276-020).  The LED has its own MOS flasher built in and
works well connected to 3 penlight cells.  It can really be seen for quite
a distance at night.

QUESTION:  Does anyone know where these little goodies can be purchased
in lots of 10 or so - the R.S. carded individual component price is
rather steep.   I want to connect 3 or 4 of them together to make
flashers for the kid's bikes.

Please reply to rafi@bguvms (bitnet).

Thanks and 73,

I was thinking about mounting a Cushcraft R7 on a flat non-metal roof
about 5' up on its side.  Any comments on how this might work.
I  assume that I should make certain that  the metal antenna
elements do not touch any part of the metal base?

I've had this setup on my car for a long time. I prefer it to having a full
blown rig, as it is very easy to slide the ht underneath the seats and out
of sight.

> What I was wondering is how I can boost the power to say 25w.

There are a few commercially available units. I have an Alinco amp, that takes
in 5 watts and puts out about 30. There are also units made by RF Concepts,
Mirage, and probably others. Expect a price around $100.

> Does anyone have schematics or suggestions for a non-tube amp for the

In addition to the above comments, Ramsey puts out a kit, for about 50 bucks I
understand, that you assemble yourself. I never heard any comments on its
performance, ease of construction, etc.

QST and the Radio Amateur Handbook have a few schematics as well.

There are a lot of options on antennas. I'm using a Larson dual band (144 and
440 MHz) with very good results. Of course you will hear similar remarks about
any other model you can think of. Prices for these are about $40-$50.

Organization: Zombie's Burial Chamber, Berlin, West Germany.

HI !

I own a Kenwood TS-850S(AT) HF-transceiver. I'd like to know
if there's any possibility to use the RF-gain within FM-mode !?

As I work on FM with lots of stations near me, the normal
18db-att an the SQL isn't enough to "kill" unwanted signals.
So, if RF-gain would work with FM-mode, I'd be much more happy.

Another way would be, if possible, to make the SQL more sensitive.
Is there a pre-adjust-varistor inside the rig for SQL-level ?

Any help welcome, tnx in advance.

Fred, the SM is NOT the person who can influence QST, at least not directly.
The HQ staff is one place to start (we have posted our email address lists
on r.r.a.m. -- email to ehare@arrl.org if you missed it, I will send a
copy). The ARRL Board of Directors can set League policy about QST content,
so as a longer term you can discuss QST with your Division Director. The SM
helps run the REAL ARRL -- the Field Organization. (Don't forget that the
League is NOT the HQ staff -- we are just a part of it (an important part,
IMHO). The rest of the League is found "out there." The Field Organization
is exactly what YOU (collective) make it.

Some of us are. I am even taking it upon myself to ensure that your comments
are directed to those who can do something about your concerns. (Even 
Dave Sumner -- he has been mentioned enough in this thread that I guess
I should make sure he sees it. :-)  ). But not all of us read r.r.a.m. all
the time, and news-feed problems happen, so it is much more effective to
actually send us email. At least we gotta' read it enough to answer you.

I must misunderstand something here, Fred. I have been exposed on this forum
for several months, as have been several of the others that work here. I
really don't know where this opinion has come from. 

I hope you don't mind that I had to correct a few minor misconceptions. I
just didn't want to see the SM besieged by calls and letters for something
over which the SM has no direct influence. Keep the QST-content opinions
flowing. I will pick up any that are posted and forward them to our editors
(if I don't miss them). You can also email me directly for a somewhat more
certain path.

Keep the frank discussion flowing, over-the-net or behind the scenes. It
is healthy as long as we can keep in constructive and seek solutions
instead of blame.

A fine critical essay!  But how about the Vision Thing?  I.e., what SHOULD
QST be like?  What other magazines, ham or otherwise, have a format that
would appeal to Hams As They Are Today?  (People, Road & Track, Rolling

What?   The type of punch being discussed is the type made by Greenlee,
often referred to as a "chassis punch."  The beauty of a good chassis
punch is that it *WON'T* warp the metal and leaves a very clean hole.
(You first need to drill a 3/8" pilot hole.)

A toothed hole saw will cut an elliptical hole unless it is held
perfectly perpendicular to the surface.

Using a chassis punch is a manual operation, and it's much
easier to control.

I've been installing NMO mounts on cars for almost 20 years using
a chassis punch -- never a problem.

       I get audible hum from a WE 2500 handset at 13" from the front of

handset not connected to a telephone, and with an Apple 13" monitor.
There's definitely a nice strong field there.

       If there's sufficient interest, I can get an AC gaussmeter
and make detailed measurements.

Then don't read it.  But I think you'll be missing some useful--and
improving--material.  QST is not soon going to publish 100+ pages of
technical material of the kind you would like to see.  It's just not
what the bulk of the readership wants or needs.  Faced with that
reality, why not do the next best thing and at least put the material
*somewhere*?  Given the available page space, which is determined by
the economics of publishing, this method lets us devote more total
pages to worthy projects than we could do in either QST or QEX alone.
Each article stands alone, by the way.  You don't need to have one
to get the benefit of the other one.

come every form of consumer electronic portable device comes with a carrying
case EXCEPT HT's???  If my W2A had come with one or my local HRO hadn't been
out of stock, my drop test wouldn't have resulted in near as much damage...

I have a chance to get a Motorola 2 meter antenna from a guy in town for $10.
It sounds okay to me, but I'm just checking for opinions...

Also, I'm going to give in and drill a hole in the roof of my car.  I've been
told so far to do take these measures:  use a sharp bit, wax the area heavily,
and use RV silicon to seal the mounting.  Any other things I need to watch
out for?

Thanks,
