Quite certain to. At the beginning, you won't know what directions
your interests will take, so your first equipment really should serve to
find this out.
The
: things I *think* I'm interested in now are the result of extensive
: reading over the past 4 or 5 months about the many facets of ham
: radio, rather than actually doing anything :). Anyway, the thought
: of communicating with someone in a far away country was what initially
: drew me to amateur radio (as is the case for many, I'm sure). I own
: a home in a reasonably unrestricted neighborhood, so an antenna won't
: be a problem. So I'm in the market for a good, used HF rig less than
: $500 if possible.
Starting this way is close to ideal. Buying an older rig, flat on
its price curve allows you to try it in anger, learn from it, and then
sell it for exactly what you paid. Free radio, free education, free
entertainment ! Even if you grow to hate this radio, at least you have
learned what you like/dislike, and as you can recoup your money, you are
free to seek something that suits your newly discovered tastes. I've
just discovered 2 ARRL books I never knew about... 2 volumes of collected
QST reviews. They cover most of the current stuff, and then all the
reasonably common radios back to the sixties.
I'm not sure of prices in your country (They're about HALF ours !)
but you may be able to find a reasonable TS830 which was once a
contester's favourite, the FT902, FT101ZD, FT102 could also be of
interest. These radios all have valve (tube) outputs which could need
replacing at modest cost, the benefit of them is that their Pi-tanks act
as a medium-range built in ATU, with about the same coverage as mnany of
the flashy auto atus in the $$$$$ radios. The RX input stage on the
FT102 is notoriously easy to blow up, but is easy to fix.
If you can find a TEN-TEC Corsair in your price range, you would
have a very respectable transceiver indeed. They have a reputation of
so-so reliability, but are easy to fix and the manufacturers are
extremely friendly and helpful. Several friends use these, and I've
fixed them when needed, I'd say there was no reliability problem, but
they could benefit from a bit of careful filtering of ancillary
connections. Amateur bands only, a delightfully clean Rx allowing you to
work things other people can't hear.
I'd like a general coverage receiver, too, but
: I don't know when they became common on HF transceivers. A good
: rig in that price range might be too old to have a general coverage
: receiver. Any suggestions on specific models I should keep my eyes
: open for?
The first rigs including general coverage were very poor, well
worth avoiding. I have a soft spot for FT102's and TS830's but I
wouldn't touch an FT757 or a TS 430 with the proverbial barge-pole. The
first general coverage job worth bothering with was probably the IC735,
which has earned a reputation as a good radio, with the inevitable high
resale prices.
I've been told that the Collins S-Line is good, as well
: as the KWM-2A. Drake was also mentioned (TR4-C and TR-7). Of
: course, I don't know anything about any of these radios, yet, so
: I don't know what would make one better than another.
These were superb radios in their day, but beware that they are
not quite as good as the legends have it. Reminiscences tend to be a
little golden-tinged ! S-line and KWM2's are now rather old, and any
ones now for sale will likely need maintenance and regular service work.
With someone local that can help, this can be educational. Second hand
prices are higher that is appropriate to their true value because of the
legends. It's a little like choosing a Bugatti type 35 racer as your
first car - it will cost in money and time, but prove educational, and
get you involved with a fairly good bunch of enthusiasts. Parts are
getting rare and are becoming expensive as these acquire collectors item
status.
: Also, I've got a 386 at home that I'd like to set up as part of a
: packet station. I've considered a dual-band HT for this purpose, which would
: have the side benefit of giving me a radio I could take backpacking
: and camping, as well as on the road. My gut feeling, however, is that
: an HT would be a compromise for a packet station as well as a mobile -- but
: that's just a guess.
A good guess, your guts are right! You won't use many frequencies
for packet, and the true value of packet is in leaving it running,
rather than trying to use it for real time QSOs... this means a seperate
radio. You will wind up, most likely, with several radios and the packet
one can be the cheapest. This is an ideal application for a
re-crystalled commercial rig, something by GE or Motorola bought cheaply
at a rally. You'll need a little help to modify it, then it's your turn
to help others.
It would be great for hiking, though. And it would
: get me on the air quickly. But that got me thinking about mobiles. Would
: I be better off buying a mobile instead. Obviously, it wouldn't be very
: convenient for backpacking -- my truck won't fit in my pack :). But I do
: spend more time on the road and at home than I do in the woods, so I want
: to try to get a rig that will give me the best value for my current
: interests. I can always buy another radio later assuming I don't get
: laid off :). Anyway, based on the catalog prices that I've seen, a dual-band
: mobile doesn't cost a whole lot more than the fancy dual-band handhelds such as
: the Yaesu FT-530. Besides, if I used an HT in the car very much, I'd end up
: buying an external speaker/mic. This would further reduce the price difference.
: I'd be interested to hear from some of you that have used an HT for packet and
: commuting and how well it's worked for you. Also, if you have both types, maybe
: you could give me some pros/cons of both types of radios for the purposes I've
: mentioned. Also, I remember a posting a few weeks back where someone compiled
: some suggestions for buying an HT. It seems like someone said that they
: wouldn't recommend buying an HT as a first radio. I'd be interested to hear
: some of the reasons for this.
You have used three key words "Handheld" "dual-band" and "catalogue
price" The market demands have steered the manufacturers towards
smaller and smaller portables, with wide coverage as a sort of built in
scanner, with longer operating times from smaller batteries. The current
products all have sacrificed RF performance to achieve these ends, they
have wide front end filters, power-starved RF amplifiers and mixers, and
have RF performance and coverage comparable to a cheap and nasty
scanner. This means that they are much more susceptible to overload from
nearby out-of-amateur-band transmissions than older models. If you want
a hand-held, I4'd recommend looking at re-programmed commercial
(Motorola, GE, etc etc) units, or old model japanese stuff like the
IC02E. Surprisingly few people are aware that modern units are prone to
blocking and overload, firstly, what they don't hear, they often don't
know they're missing, and when they know they're failing to receive
something, they don't realise that some other radios would still be
working. Don't buy an HT as a first radio, you need to learn and form
your own opinions first, finding a good one is a minefield. They are
designed to impress the non-technical. I'm not surprised that some now
include computer games ( a cynic like me would add "in place of RF
selectivity").
There are plenty of reasonable quality mobiles out there, go for
something second hand and old-ish, and treat it as a learning exercise.
I use a FT480 multimode at home, and a TW 4000A dual band FM rig in the
land-rover, I've had both for several years, both were bought second
hand, and I feel no urge to change either. I don't have an HT, If I had
a need for one immediately, I'd be in trouble, I don't know of one on
sale here that I'd consider satisfactory. Reports of a radio shack HT in
the US, with proper 2m band selectivity are encouraging.
: Lastly, satellites seem very interesting, but I'm sure that is a ways down
: the road for me. Also, I don't know if the HT/mobile could be used there
: too. Is FM appropriate for working satellites? Either way,
: I don't think this part should affect any of my purchase plans just yet. But I
: would like to hear from someone with experience in this area concerning the gear
: they use (or wish they had) and maybe the title of a good introductory book.
The keen satellite folk around here have all saved up for FT736's,
but you can get on with a few old radios. You don't need modern
multi-banders, one radio on each of the two necessary bands will do
fine. The very very serious VHF folk still use transverters into good
HF rigs.
: My budget is not without limit, so I know I can't get all of this stuff at once.
: It sort of depends on what I find first. I'm leaning toward the VHF gear
: because
: I could get on the air quicker. Also, I could set up a packet station fairly
: soon after that and really start to get my feet wet.
May I suggest an HF rig first, which will use up your budget nicely,
and then shop around for a junk commercial mobile unit to be modified
for a couple of chosen packet frequencies. On this net and on HF you can
seek a few people prepared to give advice and possibly physical help.
You can use your HF radio with a converter to listen to sat output,
and so only need a rig for the satellite input band.
The less you spend, the more you learn, which gives you a profound
advantage.
Unfortunately, there are
: not
: too many hamfests near me (Huntsville, AL), so it might take awhile to find
: an HF rig. There are some larger cities within driving distance (Nashville is
: only two hours away, Birmingham is less than that, and I can be in Atlanta in
: about 4 hours). I'll just try to keep my eyes and ears open, and hopefully
: if/when I run across the right radio, I'll have the budget available to get it.
: But the other gear I could easily order and be on the air fairly soon.
: I'm afraid I've rambled on much more than I had anticipated. My basic
: questions,
: in case you got tired of reading and missed them :), were this:
: 1) can you recommend any used HF rigs (less than $500) that I should look for?
: 2) i like (even prefer) the potential convenience of a handheld radio, but
: would
: it be a poor choice for packet and auto use?
yes it would
: Thanks for any help.

My answers have been a bit long-winded, and maybe a little
opinionated, but I hope I've covered all your questions. These are just
personal opinions, formed by acting as the local rig-fixer for a number
of years, I hope they help a little.
Good luck

Subject: Need Repair Info for Monitor
To: info-hams@ucsd.edu
A few years ago, I bought a new Commodore C-64 for the kids,
hoping they would play a few games and get interested in
computers... What happened was, they got interested in
computer games... Anyway, a couple of years went by, and
the nice little Samsung composite color monitor that we
bought with the system just up and died. Being an EE myself
and having lots of test equipment at work, I could easily
fix most little problems that crop up in such devices, IF
I only had a schematic and maybe a little block diagram and
some repair info. The kids aren't too interested anymore,
and I might set up a dedicated packet station or something
if I could get it fixed...
So, the question for the netters is: Where does one obtain
this sort of information for this sort of equipment? I have
heard that Sams Co. provides such stuff. Does any one know
a phone and address for them? Do they provide a catalog or
something? My suspicion is that the manufacturer would want
to give you a thick manual that costs its weight in platinum
and only covers one model (and probably hasn't been translated
from Japanese), if you can even find the right contact in the
company. I really would hate to throw this thing in the
junk pile (I have more than enough CRT bombs lying around
already). Thanks for any help!

Subject: Unix ham radio control program
To: info-hams@ucsd.edu
As an offshoot of my project of writing an X11 logging program, I've decided
I'd like to tackle writing a generic radio control program for Unix-like
systems. My idea is something like this:
- A server process could be configured with information about what kind(s)
of radio(s) you have, what serial ports to use, etc.
- The server would accept connections from other processes that want
to interface with the radio.
- The server would communicate with the processes using some kind of
generic radio control protocol.
This way other programs can talk to a radio without having to know anything
about the details of communicating with it. They just talk to the server
in a generic language and the server handles the radio interactions.
This brings up the a few questions, and I'd like to solicit input and
opinions from the net before I dig into this:
- What kind of functions need to be defined in the generic language?
A few things that come to mind are things like 'get frequency',
'set frequency', 'get mode', 'set mode'. What other things might
a program want a radio to do (assuming of course that the radio
supports it.)
- Are there other things besides radios that might be controlled?
Antenna rotators? Antenna switches?
- At some point I'll need details for the various known controllable
things, like the command language for Icom, Yaesu, Kenwood, etc.
Maybe people on the net can help provide these things for me.
After getting lots of response to my earlier posting about the X11 logging
program I'm beginning to think there are lots of people running unix-like
systems (mostly Linux) in their ham shacks. I'm hoping that I can come
up with something that will serve the needs of a variety of interface
requirements so that people can start linking up their unix boxes with
their radios.
