        Hi, I have run into a BC-100XL scanner for free (as it did not
work).  I tracked down the problem to a slightly toasted resistor.  Could
someone tell me the proper value of R94 please?  Also, if anyone familiar
with the scanner could give me any idea of other features (ie. exact
frequency coverage, how to work searches etc...)

Thanks in advance,

When I talked to the folks at HAL last month, they indicated they would
release clover design details "sometime in the future"  Until then, they are
going to get whatever they want for it, it appears.
Without competition there won't be much downward pressure on the price.
If you had purchased one before the first of the year, you could have had it
for $750.

We need a "public domain" system to be distributed to multiple vendors, like
TAPR has done.  That is probably the only way we will be able to have reasonable
prices on advanced communications modes.  As long as the modes remain
proprietary, they will be expensive.  Anyone care to form a committee to design
such an advanced mode?

Subject: FM and fences
Date: 11 Jan 93 10:15:13 GMT




I fly radio control model aircraft, but recently the club
flying site has been experiencing radio interference problems.

There is no fixed pattern to the interference which can range
from severe on some days to non-existent on others. Some of
the members believe the interference is caused by the recent
addition (some 18 months ago) of a 3 strand wire fence, fig 1,
and that the interference is caused by the fence when the
atmospheric conditions are just right, (general consensus
among members is high humidity). Members that can remember as
far back as 18 months believe these problems did not exist
before 'the fence' --- are they right?

All radio sets are FM and have been tested to conform to the
manufacturers specs.

My question is:-- is this possible??, and if so how can it be
prevented without demolishing the fence, (since the farmer
likes his fence).

Fig 1.

The layout of the site is:-

If it is impossible for a fence to be causing this problem
then the hunt will be on for other radio sources in the area.

True.  Coordinators have the attitude "if it buzzes, we don't do it."
However, as a wise person observed, "Packet people don't know s**t about
radios; Radio people don't know s**t about packet."  In the general case,
regrettably true.  Packet folks aren't experienced enough to deal with
coordination lore.  AND they don't consider full-duplex regenerators
(aka packet repeaters) as repeaters, because some of the bits get changed.
They really don't but that's a nit.  I maintain that there is a signal
that is being received, and the information is being retransmitted in
real-time.  THAT's a repeater, and coordinators should be able to 
coordinate those, because it's the case that the frequencies need to be
(Oh Gawd, they'll pounce on this...) "protected" by coordination.
Simplex (standard digipeating) packet systems should NOT be coordinated,
at least in terms of spectrum.  Packet groups, if they are stupid enough
to get into it, should coordinate that.  There's coordination, then there's
coordination.

In the pure sense, repeater coordinators should not represent ANYBODY.
They are a central, neutral, organ that should be used to COORDINATE
the usage of spectrum, under the "accepted standards".  The group that
decides the "accepted standards" consists of the folks that represent
whatever factions that obtain.  Rather like the Geneva Convention, I'd
venture.

What does one reply to a SWL card?  I got one recently, and didn't realize
that some sort of reply was appreciated.  Just a note saying thanks? or is

I have the NC-29 (modified) and think it is decent.  With the modification,
you don't have to quick charge for the full 5 hours, but can run the timer
down to whatever you want.  I agree that if the power goes off/on during the
night, it could cause problems.  Maybe the "run down timer button" should
be a switch that you leave "on" so if the power does go out, it will fall back
to trickle charge...

    I made my own power cable using the Radio Shack power plug
p/n 274-1571  (3.5mm O.D. and 1.3mm I.D.) and a cigarette lighter
plug.  I would, however, recommend some type of line filter as the
radio picks up quite a lot of alternator noise (on transmit) from the
cigarette lighter outlet.

Good luck!

About 15 years ago, my bank in New Hampshire had a small logo available
showing a ham in front of a radio with a mic in hand. However, I don't
remember who the check printer was, although I suspect it was one of the
bigger ones. (Unless they allow 2 logos and can fit the "Star of Life" on
our checks for my Paramedic XYL, we'll be settling for plain text for now).

There are a lot of "third party" check printers (i.e., who do it free-lance
as a result of a direct order from you, not through a bank), so shopping
(and lobbying) around seems to be warranted. Amway has an agreement with
some place, so you can order checks through them. (Basically, you order from
your Amway distributor, and get a voucher/order form in the mail that you
complete and send to the printer. This is not to be construed as an
endorsement for Amway, but as an example of what sort of arrangements can
be made). Hopefully, this thread will generate enough interest to encourage
the printers to come up with something.

Nope!  This tactic was tried in LA by jammers in the 1970s...and
it didn't work.  They figured they had found a loophole....since the
repeater was not transmitting on top of THEM.  No one was amused!

Gosh, I *THINK* so.....but maybe not!

Are we talking about AMATEUR radio, with people who have some
idea of the history of the development of FM repeaters and coordination?

Regarding simplex QSOs.....of course no one is going to get in big
trouble by accidentally stumbling across the odd frequency or input.
But I thought we were talking about a bunch of folks on this newsgroup
who think they have found some loophole to harrass operators of
links, closed repeaters, or any other spectrum usage that they don't
like.

I have a question about your review of the 5100....

On the scan function, when running PL decode, will it stop on a busy channel
even if the wrong pl is there, or no pl at all, and just mute the audio?
Or will it just skip over it, just like my Kenwood TH-77?  

I have the Yeasu FT-212RH and when I decode PL on a memory, and I am scanning,
if a signal comes in on the same freq. as the decoding channel, the scan will
stop yet the audio is muted.  (Do you understand this?  It's almost confusing
me as a write it! 8^) )

Thanks for the help.

First, is this radio modifiable for out of band transmit?  If so, what
frequency ranges.  Please no flames/comments about type acceptance.

Second, how does the radio handle odd offset repeaters?  Do all/some of the

>My grandfather was a radio amateur (he got his license in 1913). I have a collection of QST's from the 1920's and a bunch of QSL cards from the same period. Are these worth anything? Many of the Qst's still have their covers but most have either lost their covers or the covers are loose.

The QST's are certainly worth something.  The QSL cards probably not.
