I am looking for a 2m mobile unit, at least 45-50 watts. Any suggestions as to
brands and features needed would be appreciated.
Thanks,

Local news for VK2 WIA members
==============================
As a result of a meeting of concerned members of the WIA which
was held in Sydney recently, a committee has been formed to
encourage independent candidates to seek election to the
Council of the NSW Division of the WIA at the forthcoming
Council elections.
The committee consists of Peter Naish VK2BPN, Bob Mayer
VK2BMU, John Brooke VK2FUR, Alan Dark VK2XAT, Roger Henley
VK2ZIG. No member of the committee will stand as a candidate.
The committee can be contacted at PO Box 372 West Ryde NSW
2114.
-------------------------------------
Guidelines for the preparation of programs for transmission by
-------------------------------------------------------------- Amateur Radio Teletype
======================
from Frank VK2FJL
part 2.
-------
(2) UNSHIFT-ON-SPACE.
Some RTTY machines and most computers automatically change
from (FIGS) to (LTRS) every time a (space) is received.
To defeat this feature when text containing both spaces and
figures is being prepared : e.g. Satellite predictions, it
is necessary to insert a (FIGS) immediately before each
upper case character which follows a (space).
(3) PARAGRAPHS.
Commence each paragraph with an extra (CR)(LF) - i.e.double
spacing - and type four spaces plus a (LTRS) or (FIGS) be-
fore commencing the text.
(4) HEADINGS.
Un-numbered headings should commence at the lefthand margin
and be underlined using the hyphen on the next line, with
double spacing both above and below the underlined heading.
(5) PUNCTUATION.
Your layout will look neater and text be more readable if
the following suggestions are used.
(A) FULL STOP - This follows directly behind the previous
letter, but allow two spaces after each full stop.
This may later be expanded or contracted to fill the
line to the right-hand margin.
(B) COMMA - This also follows directly behind the previous
letter, but with only one space to follow.
(C) HYPHEN - When used to punctuate a sentence - type
(SPACE)(FIGS)(HYPHEN)(LTRS)(SPACE) and resume the text.
This can later be expanded to two spaces on either side
if required for line fill.
(D) QUESTION MARK - This looks better when preceeded by a
space and followed by two spaces. Like the full stop,
This may be expanded or contracted for line fill.
(E) COLON - Also provides clearer text when preceeded and
followed by at least one space.
(6) TABOO'S.
The use of the following characters should be avoided as
different keyboards will them as print different things :
semi-colon, equals, percent, dollar sign, pound sign, plus,
ampersand, quotes, maltese cross, exclamation mark and
the bell.
The question mark, colon, hyphen and apostrophe also differ
on some keyboards, but as their use cannot be restricted
entirely, it is obviously impossible to please all of the
people all of the time.

IPS weekly report
-----------------
14 January - 20 January 1994
Issue no.: 03
Date of issue: 21 January 1994
Date 14 15 16 17 18 19 20
10cm 90 96 100 105 101 103 105
A 18 18 14 23 21 21 (10 estimated)
T 63 42 11 41 59 25 29
Summary of activity
Solar activity was very low 14th-15th January, and 17th-20th.
Activity was high on 16th with an M6 flare.
The geomagnetic field at Learmonth (WA) ranged from unsettled
to unsettled to active with a minor storm period during local
night on 19th.
Ionospheric F2 critical frequencies at Sydney were slightly
above predicted values on 14th and 18th, near normal most of
15th, 17th and 20th, and slightly below on part of 15th, and
19th. Sporadic E blanketing was often present from 15th - 18th
January.
Comment:
Sporadic E was often observed this week. HF conditions may
have been degraded due to mild geomagnetic activity which has
more or less persisted since January 11th. The source of this
enhanced geomagnetic activity is thought to be a broad south
polar coronal hole.
IPS Monthly predicted smooth T-indices

While we're on the subject, it's worthy of note that (apparently by FCC
fiat):
* the color subcarrier is 3,579,545 Hz +- 10 Hz
* the horizontal scan frequency is 2/455 times the chroma subcarrier freq.
* the vertical scan freq. is 2/525 times the horizontal scan freq.
So, 14,318,180 Hz makes a fine frequency reference for generating sync
as well as a neat sampling rate for frame stores.
Don't know if this has been said before, but I haven't seen it (recent
news troubles here... meeee, screw up the permissions? Nawwww).

That's not "normal" component tolerances. That's a blown front end.
It was either blown, built wrong, or mismeasured.

Ah, this brings back fond memories of the early 1960's. The
commercial services were replacing their wide band FM radios
with narrow band FM boxes. For a mere pittance, you could
have a 60 lb block of sold iron, complete with a Carter Super
Motor Dynamotor, Mallory synchronous vibrator power supply,
loctal tubes, and persuader microphone. (Ah, nostalgia).
With a starter relay to the on-off switch and welding cable
to the trunk, one could have a radio far superior to the typical
"ham" AM (not FM) radio of the day. "Goonie-birds" (Gonset
Communicator I thru IV) were grossly inferior to the average
commercial radio. Why would anyone want a non-commercial radio?
Well, there was a sufficient supply of conservative arguementation
favouring AM. (Incidentally, I was in Los Angeles during this
time). Although I was on the FM side, the only arguement that
struck home was "What would you do if the ONLY source of radios
was commercial surplus"? You're asking a small kit manufacturer
to compete on equal ground with used equipment. Since it is
almost impossible to produce a finished radio in the uSA that
will compete effectively with Japanese imports, now you ask
the same manufacturer to compete against USED equipment.
If the only place left for an American manufacturer of radio
equipment is the kit market, methinks that it is a major
miracle that they exist in the first place.
If the quality of the product offends thee, I suggest you offer
improvements instead of criticism. Please realize that additions
cost money, and that one should only suggest additions that one
would be willing to pay for. For example, don't suggest a Heathkit
quality manual as this will probably cost $70 per kit. I'm sure
Ramsey would be interested to know what the customers want to see.
While I agree that the kits leave considerable room for improvement,
I do not consider them to be completely worthless, or non-functional.
I don't have much faith in ham radio as a technical hobby any
more. The derogatory term "appliance operator" now applies to
most of the licencees. I was recently involved with a local
distributor of ham radio accessories. Many customers could
not wire a simple tnc or phone patch to radio connection. The
level of expertise in both radios and computers was disappointing.
My hat's off to anyone that builds a kit now days. Tis a rare
and apparently dying breed.
