You can find a more detailed explanation of the protocol either on
ARRL info server or at HAM-server@Grafex.sbay.org.
Both are automated mail servers so you have to send a msg like :
INDEX
QUIT
in the message body (QUIT should be used if you get problems with the .sig).
I've been through this same days ago and I find the file at GRAFex quite
comprehensive (I only miss a couple of info yet to start my project). Don't have
the arrl version handy but I would imagine that they are more or less the same.
If you need a copy quickly, let me know your email addr and I'll send it to
you.

I've been bugged by the way ARRL writes BAUDS for several years.
Look at it this way, a HERTZ is a cycle per second. Do we say HERTZS?

To: info-hams@ucsd.edu
Those of you who sent me such inviting and pleasant email, thank you.
I haven't gotten back to all of you yet, but I will. Others worried
that I don't yet have a ticket and I'm playing with HTs. Let me put
those of you at ease; I haven't touched the PTT button yet. I am
working my way through the study book...
Being a computer programmer, I am indulging my fascination with the
hardware and protocol surrounding two-way communications. A few
questions have come up in my explorations that I think are
appropriate for this list.
I've modified my Kenwood TH-78A by removing diodes 4 and 5 as
specified and it's now able to do cross-band and rx 300-399 and
800-999 Mhz. The latter carries cellular traffic across a range I
haven't yet determined, but the former seems to be perpetually
quiet. I'm guessing that there is a reason that this band is made
available...
What are the other three diodes for?
Do I need (and does someone make) an antenna that handles all four
bands?
I'd heard it said (back in CB days) that a mobile antenna interacts
with the vehicle it's mounted on: a center-of-the-roof mount made
for a round pattern while a rear-bumper mount makes for a cigar-
shaped pattern that leads the vehicle. Is this true? Does this
affect whip antennae that drape over the entire vehicle?
Thanks again, and I look forward to joining your ranks. :-) M

X1 to be any submultiple of the desired FO FO/9 being the closest you
can get, cuz the xtal runs in its fundamental mode only.
A 3.58 mc TV crystal will , on 41st harmonic, give 2 mtrs +/- error of
course, ... so you may wanna keep that in mind.
putting a series cap---variable--- to the xtal (get one a hair low
in freq)...you can tune it up to proper freq. Use => 70 pf to do it.
Coil L1 to be .05 to .1 uh 6 turns on a bic pen body, adj length
to help C1...10-20 uuf variable ( or use 10uuf fixed and adj coil only)
Coil L2 to be 1 - 1.5 turns...leading direct to ant whip.
HOW IT WORKS
The ckt is plain ol' R-C osc, with 47 pf and 100pf ( which may need to
be made twice the values in some cases* ) as the feed back caps.
The collector sees gnd AT the xtal fo due to the tiny uh there...BUT
the coil L1 and C1 act as a trap for 146mc band, and so extract what
little amount of harmonic energy there is ( not much , but...).
The osc then operates like any other, other wise...you'd NORMALLY take
RF from the emitter via 4.7 to 10 pf.
In THIS case tho, we WANT the harmonic, so L1-C1-L2 is put to use.
RF out put is on the order of u-watts ... suited for use as sig gen to
align radio sets with, or to acid test the hearing ability of it's user.
(abuser?)
The cheapest of 9v batterys will give 15ma for 28 hrs...so HERE we are
talking about like 280 hrs...no need for a power supply
As this ckt will work from 5 to 18 volts....
you could series up AA cells or solar cells if you wanted to...
HOW TO USE
As you get rig aligned so it can hear the test osc up close, just move it
further away.
Receiver to have a 56 ohm resistor in place of the antenna, so you don't have
have to put the test osc across the street to make it weak enough to be
50% full quieting.
After tweaking Rx for best reception, re-move test osc futher away...etc.
* In some osc's 47 pf has to be 100pf and 100pf has to be 180-220pf.
This affects exact freq and is dependant on what frq xtal you use.
the 47/100pf was for 10.7 mc but the 100/180-220pf was for 3.58 mc.
If osc fails to work and you KNOW its hooked up right-transistor is good,
then change those 2 caps...maintain about 1:2 ratio between 'em
Practical values will be *with-in* 4.7pf to 470pf for freqs of
100kc thru about 16mc (fundamental modes)

OK, let's open up this can of worms.
PREFIX - 1) to place in front 2) an affix attached to the beginning of
a word, base, or phrase and serving to produce a derivative word
or an inflectional form
Thus, I believe that K5 is the prefix component of my call. That makes it
unique from W5FO, WA5FO, KN5FO, .....
We have the Continental US divided into 10 zones, etc. At the present time
this division means nothing. Any ham permanently residing in any zone can
own any call from any other zone from which they transfered, bringing their
old call with them. Is this country the only one in the world, where a
country is divided up into zones or regions assigned specific prefixii (;-) ),
that currently allows this?
The reason this is a bother - if i'm looking for a state, etc. for an award
or multiplier in SS or whatever, I have no earthly idea on their geographic
location any more. Does it bother anyone else?
Carrying this further. Can I sue Arizona, if I should chose to move their,
to allow me to bring and use my Texas license plate tags? Me thinks not.
Carry this own to the international level. Can a ZD9 move to TU land or
whatever and take their call?
So can we go back to the division with the new opening of the calls missed
or whatever and get the system back in order?
Just a nit pick. It's not like the call is you. You are you. Dubs on K5E.

Well, I think in the US, each call must consist of a prefix of one or two
letters, followed by a number, followed by a suffix of one to three letters. ITU
regs are more complex, but prefixes still don't include a number.

Yes, I can't stand it. Cheap for the FCC is the only reason.

Bad analogy. Callsign are Federal - as long as the prefix and format are right,
how FCC assigns calls is up to them. Registration is a State matter. The
Sovereign State of Arizona can tell you to stick those Texan plates up your
tailpipe, if they want to.
|> Carry this own to the international level. Can a ZD9 move to TU land or

Huge difference. ITU treaty requires the prefix be right, even if it's like
"VE2/KG2S" (Yes, I know I can't legally do that for Canada, it's gotta be
KG2S/VE2! What can I tell you ... ) US rules allow you to use /extensions, but
it can't be something that sounds like you're overseas, and it can't be KT, AG,
AA, or AE (and now you know why it's KT and not AT!)

No, I really think most amateurs consider their calls to be parts of
their identity.
