I strongly suggest that before even *thinking* about touching
your incorporation paperwork, that you get a lawyer. The first
question to ask is, "If we change any of this, do we have to
make the rest of it confrom to the current law?"
Many states have had problems rise from non-profit/club situations
and have set things up so that anytime any part of such documents
are changed, the whole thing Must be made acceptable for the
law at the time the changed document is submited to the Registar
of Corporations (by what ever title.)
... and as to the by-laws, make sure that you do what ever
drill is required by the corporate charter that is in
effect at the time that you do them.

Subject: Help! SB-200 Problem
To: info-hams@ucsd.edu
I recently bought a SB-200 and decided to "upgrade the circuitry." My
modifications consisted of the following:
- Replaced the power supply's 125 uF 450V Electrolytic Twist Lock Can
Capacitors (Which were leaking. New replacements are very expensive and
difficult to find...) with brand new 220 uF 450V electrolytic capacitors
(Panasonic TS-Series).
- Replaced all the power supply diodes, and bypassed each with a 0.01 uF
1 kV ceramic disc capacitor and a 470k 1/2 watt resistor (for
equalization).
- Replaced the Parasitic Chokes on the 572B Plate Caps. Old chokes were
3 turns wound on 47 Ohm 2 W resistor. New chokes are 2 turns wound on
56 Ohm 2 Watt resistor.
- Repaced 0.001 uF 3kV bypass capacitor on Plate Supply with new
0.001 uF 10kV.
- Cleaned bandswitch.
The following illustates the amplifier performance before and after the
modifications were applied: ("After" Values shown in Brackets)

100 Watts Drive used for all measurements.
Exciter is SB-1400 in CW mode.
As expected, the power supply improvements generally resulted in a somewhat
higher plate voltage and a corresponding higher RF output. HOWEVER, the
performance on 20 Meters is greatly WORSE !!!
a. There is no difference between 20, 15, and 10 meters on the
the output network, except for the obvious coil tap and cap setting
differences (i.e., on 80 meters, additional fixed caps are switched
in), so there are no "unique" output components on 20 meters to fail.
The tune/load caps are clean, and all solder joints are good.
b. I placed an SWR bridge between the exciter and input of the SB-200
to check for input network problems (mismatches). Match was better
1.5:1 on all bands, including 20 meters.
I have considered the possibilty of a bandswitch problem. However, the
20 meter switch position is used to tune for 30 meters, which performed
extremely well, indicating the bandswitch is good. [By the way, I AM aware
that the maximum legal output on 30 meter is 250 watts. I was testing
on the 10 MHz band to get an idea of the amplifier's frequecy response.
Please, no flames. I do NOT intend to QRO on 30 meters.]
I have swaped the two 572B's with EACH OTHER, but have NOT tried new tubes.
Anyway, I doubt seriously that this is the problem.....
I've not probed with a scope and RF probe yet. I'm not sure what to look for.
I'm baffled. Any ideas?

You need a source of zero reflected power - called a dummy load (rated
at the frequency of interest of course). Stick it on the "out" side of the
SWR meter, put the meter into forward mode, adjust meter for full scale
deflection, then put meter in reverse mode, you should get no reflected power.
FOr how to convert the reverse and forward paower into SWR , look up a manual.

Subject: How to Calibrate an SWR meter
To: info-hams@ucsd.edu
Hi
On the front of the meter it has got a 'Calibrate' Pot, and a switch marked
FWD and REF not REV for reverse but REF for referance, is it the
same difference ?
On the meter it is has got several scales, 1 to 5 acros the top with 3 to
5 in red, at 5 it has got a point marked set, and underneath it has got a
scale going from 1 to 3 but reading 0 to 25 %
So If I understand it right, with no reflective power ( ie a dummy load
straight on the output) and the switch in FWD mode I should set the needle
to the 'set' point ( 5 ) when I am TX on full power. Then with the switch
on REF it should read zero ( reflective power).
With the output open and TX full ( being carefull not to blow my rig up )
the reflected power should equal the output power.
Thanks for the help if the above is correct, if not I think I need a few
more explanations.
Thanks
Kevin

To: info-hams@ucsd.edu
I have several pieces of equipment suitable for the prospective
museum curator or nostalgia buff. These are free if you can get them
from my place to yours. These include: a Model 19 TTY and one (maybe
two) spare TDs. I also have two typing reperforators. I don't recall
the model number, possibly Model 28. The last item is a McElroy
Morse keyer. It sends CW practice tapes at continuously selectable
speeds. It is a beautiful piece of mechanical workmanship. I think
it was used by the military for training in the WWII/Korean conflict
era. As I recall, it is the prettiest sounding CW that I've heard
since taking my amateur exams before the FCC at their offices in DC
and New York. The code to be sent is punched onto a paper tape
approx. 3/8" wide. I have a typing perforator that goes along to do
this.
All of these were in working order the last time I used them (that
has been a decade ago). I hate to haul 'em to the city dump but they
are occupying garage space that must be used for other things.
If you are interested, or know of someone who might be, let me know
on the net, by e-mail or via my CBA.

The FCC has said they may do this in the future. I gather the new
computer system can handle it. The idea of callsign reuse is usually
bundled with the proposals for vanity and club callsign assignments,
though I suppose there's no reason it couldn't be done by itself.

I used to have this problem with my TS940 after I moved the transmitting
antenna closer to the operating table. I discovered the cause to be RF getting
into the PTT line of the microphone cable. The problem was cured by placing
a large split bead around the mic cable close to where it enters the rig. I
haven't seen the problem since then. I suppose a bypass cap across the
PTT line to ground would also be a good idea, but the bead solution was
successful and easier to implement.
By 'powering down' do you mean reducing RF power or shutting off the rig?
The symptom that I described would be affected by reducing RF power as well.
Good luck!

Yes, that's absolutely true. I upgraded to general by just taking
the 13wpm test last December. I was a "grandfathered" tech

If you can prove you became a tech before (damn, I can't find
my VE handbook so this is a best guess) about Feb 1987, then you'll
be given credit for the general theory test. Does your
duplicate license show an issue date of before '87? If not,
then I think a copy of a 1986 or earlier callbook that shows
you as being a tech would also suffice.

It has been over ten years since I have been to the British
Virgins, but my dad and I both got reciprical licenses when we
went. There are good repeaters down there and you can hit many
islands at once, depending on your location. We rented a sailboat
and were able to communicate throught the islands at all times.
Certain repeaters will be blocked by mountains on the islands at
times, but overall, it was beneficial.
By the way, I believe 3rd party traffic is still illegal within the
BVI's and their territorial waters, so be watchful.
Have Fun. It's easy to get the reciprical (just paperwork & $20).
