I completely agree on both counts. My present code speed is 55 wpm,
and I'd be REAL hard pressed to do it without a keyboard.
Although, I did just that at an ARRL convention out at Glacier
National Park a year and a half ago -- with a pencil.
There we were -- in a TENT, no less -- with all contenders having
long ago given up (at around the 40-45 wpm mark), except for myself
and one feller from Western Canada. We gave each other the evil
eye across the table, and asked each other if we were gonna try
60 wpm, to which we agreed, dull pencils and all.
We walked out of the tent not knowing who had "won" the little
contest, until I stuck my ear up against the tent walls (neat trick)
and overheard the examiners saying something along the lines of
"geez, I can't read EITHER guys scrawling, can YOU?" "Nope". "well,
which guy won?" "Whelp, how about THIS feller; I see what looks
like a couple correct characters there that I can actually read."
I still didn't know who had won.
Got a check in the mail one day a few weeks later, claiming that
I had won both that and the QLF (sending with your left foot)
contest. I returned the check, suggesting that they might
consider using the money to help a newcomer get rolling nicely.

This is, I believe, a telephone number. 387 is the Bosnia country

six are the local number. Sarajevo, for instance, is 387-71-XXX-XXX. Some
local numbers do have seven digits. The amazing thing in this war is that
the phones will occasionally come to life and people trapped inside can
telephone out. It is much more difficult to make a call into the country,
since the few lines that remain are almost always busy. Good luck if you try
to get through. I have been attempting to send a fax to the United Nations
Protection Forces in Sarajevo on behalf of one of our local correspondents there for
nearly two weeks without much success.

Hello all. I just got an Oldsmobile Cutlass with a center, floor mounted
console. Kind of like "four on the floor". Looks real sporty but
absolutely no place to mount my dual band Yaesu FT-5100 rig. Can someone
who has solved this puzzle help me out? How did you mount your radio?
Must be vertical along the console but how did you attach it. Does
someone make a vertical mount that slips over these consoles or maybe you
put velcro on your radio. Anyway, I'd appreciate some suggestions on the
best approach. Tnx es 73's...

I heard a strange story on the CBC last evening. The report was on
the increasing interest in nudism in the Winter months. To promote
this festive and relaxing activity additional interests where specified.
There is, according to the CBC, a nudist amateur radio club.
I am wondering where, how many members? Anybody know anything about this?

Supposedly, 14.265mhz, 4pm,(pst); Thurs.
Unfortunately, my antenna is marginal, and at that time of day all I
get is hash on 20m, so I haven't been able to check in. Maybe I'll
try again tonight.

Today I called the FCC in Washington and spoke to Tom FitzGibbon, who
works in the Amateur Radio section of the Private Radio Bureau. He
told me that the FCC exercises no jurisdiction over radio stations in
Canada, that a US-licensed amateur operating there under the
reciprocal agreement was free to use any frequency or mode authorized
by the Government of Canada, and that the same was true for all other
foreign countries as well.

My guess is no. When I sent a card to N7RO for a station that has
F6FNU as a mgr, N7RO sent it back to me with a note saying that F6FNU
requires direct qsl. I bet N7RO knows about this. :)
BTW, I have a 100% QSL return rate from F6FNU. I only include cards of
one station in an envelope, include a euro size SAE and two crisp dollar
bills.
BTW, I read in the CQ Almanac that F6FNU is a manager for over 450 stations.
The largest number of all managers.

Seven outgoing qsls to a dollar. Sorted by prefix. No more than 6 months
old. CBA ok.

I found the butane torch to be overkill... exploding the solder into
a vapor. What I favor is the use of copper tape... fan back the braid,
wrap copper tape between the inner insulator and the braid and then
solder the braid to the copper tape. Then solder the copper tape to
the coax connector. This may change the impedence slightly (could be
for the better :-)) but the soldering is extremely easy as the copper
tape can be used for a snug fit inside the coax connector, and the coax
connector can also be soldered to the copper tape at the base of the
connector. This works well on 9913 and pl259s.

I got a chance to try one here in the ARRL Lab (a torch type, not one
that heats a soldering-iron tip). It worked okay, but I still think I
prefer the big soldering iron. Of course, I must point
out that I have had umpteen years experience with the big iron and
only about 10 minutes experience with the torch. :-)
The fact that I was able to use it after only a few minutes practice
does suggest that they work. I would much prefer to carry
one of them off on a Field Day wilderness expidition, or up a tower,
that an electric one. :-)

This is a well documented problem. The easiest way to solve the
problem is to cut the audio wire (audio from PK232 to TS850) right
at the PK232 connector. Then connect the FSK out (on the PK232) to
the FSK in on the TS850. Use FSK mode exclusively for digital modes.
The rf you think you hear is coming in on that wire. I did this
2 years ago and things are fine now. No need to have this wire
since you really want to use FSK (vs AFSK) for digital anyway.
There is another way to fix it which involves modifying the TS850.
Send me a SASE and I will send you the Kenwood Service Bulletin that
describes how to do it.

Ok, apparently I'm not analyzing this case properly. Here's the way
I see it.
Dipole split by infinite ground plane.
|
|
-------/\/\/\/\---o | o---/\/\/\/\-------
E1 | E2
|
|
If we apply drive to E1-E2, equal currents are driven into each element's
impedance. So the halves of the dipole have equal currents flowing in them,
but 180 degrees out of phase. With the infinite ground plane isolating the
halves, one half has half the total current flow.
