The Station Today

Radio Free Raubsville consists at the moment of old radio
equipment:
- HF: Henry Tempo One (Yaesu FT-200), ca. 1976
- Realistic HTX-202 2M FM hand-held, ca. 1992
Impressive, isn't it?
There is a state-of-last-year's-art laptop computer - a Dell
Inspiron 700m - that does nothing more than run Win-EQF for logging.
(It's not as though I can control the FT-200 with it!) I can't even
use it on our high-speed Internet connection, because the WiFi
router sends hash every 2kHz on 20 meters. So when I work 20m, I
leave the Dell in the other room, turn off the WiFi, and use my
trusty ARRL Logbook I've had since I was KB3AIM in 1992. If I'm
working a contest, I have to transfer the paper into Cabrillo format
by hand. (!)
So when you read the following, you'll know why I'm being so
thorough. (You also know why I'm not going to win the ARRL
Sweepstakes anytime soon.)
Antennas consist of a low dipole for NVIS on 75m and a homebrew
vertical for 20m. At least I can get out (after a fashion).
Look at the bottom of the page for
N3OYA's diary of station-building!
Rebuilding N3OYA
The station is in the process of being rebuilt. Most of the
equipment was sold several years ago, when Real Life ™ prevented
spending time on the hobby and rented living quarters prevented both
good station equipment installation inside and good aerial
installation outside. It is slowly being replaced, however, and I
thought sharing my research would be a good idea for other amateurs
kitting up for operations.
In a perfect world, I'd have the Yaesu top-of-the-line
transceiver, complete with amplifier, towers, and directional
antennas. Since my world is far from perfect, I've got to come up
with another plan.
Usually, advisors tell the enthusiastic purchaser of equipment
whose pockets are shallow indeed -- in other words, me -- to choose
between two simple options:
- Focus on one area of interest and get less equipment, while
getting the best equipment for that interest; or
- Get generalized equipment that won't excel at any one facet of
amateur radio.
There are too many areas of interest for me. I want to do
emergency work, but I still want to be a competitive contester
(well, as competitive as a hundred watts and wire antennas can be).
I'd like to sate my long-unsatisfied QRP jones. I'd like to have the
ability to crank out more dB, though the legal limit isn't that
important. Plus I'm poor as a churchmouse.
So what to do?
I guess I'll have to get compromise equipment.
Thankfully, I know what I like and what I don't. So hereafter you'll find
lists of my criteria, followed by discussions of equipment options
and maybe a choice or two.
First I'll need a reliable, basic HF
transceiver.
The HF Rig - Needs
-
Simple control
layout
- RIT
-
Split
operation
-
Relatively low
cost
Simple, huh?
The HF Rig -
Wants
-
DSP
-
Speech
processing
-
Internal CW keyer
Not much more, is it? I already know I'm not a
"bells and whistles" type of operator (there goes the FTDX-9000), so
we can keep it simple and save some money along the way. I also don't want to wade
through seventeen different combinations of menus and hotkeys to get
to a setting I want to adjust.
Given the above criteria, let's see what's out there
on the new-radio market: (List in no order of preference. Hell, it's in alphabetical
order, because that's how the catalogs list stuff. Prices from AES, as of
02/02/06.)
| Alinco |
DX77T  |
$699.99 |
| Icom |
IC718  |
$599.99 |
| Kenwood |
TS50S  |
$699.99 |
| SGC |
SG-2020ADSP2  |
$795.00 |
| Yaesu
|
FT840
|
$599.99 |
Now, let's start the process of
elimination.
First out is easy: the Kenwood. The technology is quite old,
and it's too small for me to reliably get hold of all the
controls. I only
included it out of guilt, anyway (because I wanted to include all of
the Big Three), since it compares more accurately to the small
mobiles offered by the other manufacturers. I wonder why Kenwood
doesn't have an "entry-level" HF transceiver? Maybe someone can let me know.
Narrowing the others is more difficult. I used to have an FT840, and
enjoyed operating it.
Made a passel of contacts with it, enjoyed the audio on both
transmit and receive, and liked the simplicity of it. Compared to the others,
though, it's as old as the TS50S, and lacks "all mode" operation (AM
and FM boards are optional).
It also lacks DSP, standard receive filters, an integral
iambic keyer and front-firing speaker. It's pretty rugged and
simple, and I know it well.
Those are plusses.
But the minuses outweigh
those.
The Icom IC718 is a few years old. It's quite an impressive
piece of equipment, with good reviews from EHam.net. Comes with an integral
speech processor and iambic keyer. Also comes with everything I
want from the list above.
It does have a menu-based adjustment system, but it appears
to be fairly simple, with only two levels of menu. Everything else is knobs and
buttons. On the
downside, internal receive filters are an option. But there is a $50 rebate at
the moment, which means the cost for the unit is $549.99. And with the DSP, maybe I
won't need the hardwired
filters...
The DX77T is Alinco's first foray into the "desktop
base station" market.
It looks like the IC718, and it's got alot of the same
features (though without DSP).
I wonder... Anyway, it gets good reviews, and I like the fact
that it's not from one of the Big 3, but that's an insufficient
reason to seriously consider it, based on price
alone.
Plus, with the various specials we're seeing these
days, the price of the Icom continues to drop. A visit to http://www.kjielectronics.com/special/offer01.shtml
showed me a complete HF station for $799, shipped. There's a few things I
neither need nor want, like the straight key and G5RV (I hate "do it
all" antennas; no such panacea exists). But I'll take 'em, just in
case my trusty old J-38 and all my homebrew aerials vaporize
themselves.
But I still haven't talked about the SGC. The
little 2020 has standard 2nd-generation DSP (which SGC calls
"advanced"), an integral keyer, and is a really rugged little
bloke. I've used SGC gear before, and they really take a
lickin', and they're wonderfully simple to use. The
downsides are that it puts out a mere 20 watts at full power
and costs more. But that also fits my QRP addiction, so...six of
one, half a dozen of another.
But that's
not really a problem, since Communications
Concepts supplies HF amplifier kits to get me somewhat beyond
100 watts at a reasonable price (and the wonderfu smell of hot
solder...). And I love the militaristic look of the radio; it
appeals to the soldier still living in me. Hell, you can get it
with a manpack option, complete with H-250!
So I have
to make up my mind.
The Bands Above
HF
I had considered getting one of the new all-mode,
most-bands rigs like the Icom IC706MkIIG or Yaesu FT857/897, because
the cost would actually come in below seperate radios. I decided against it for
several reasons, the most important of which is that I'd like to be
able to talk on and listen to multiple bands at the same
time.
There was also packet to be considered, but since
we've got a wireless network attached to a cable modem here, there's
no reason to dedicate a VHF/UHF radio to sloooow transfer of ASCII
text. If I want to look
at the DX Cluster, I'll telnet to a cluster node. That said, I'll be looking
for either a radio that has a packet TNC built in or a cheap packet
interface, just in case everything goes to
pot.
As an aside, I do have an inclination to VHF and above
long-range communication at some point, but for the moment FM will
do fine.
It's simply more versatile to have seperate radios for
HF and VHF/UHF. That
makes it necessary for us to shop for another radio.
The same criteria hold forth for a VHF/UHF radio as
for HF, at least for me.
I need something uncomplicated, rugged, and with more than a
few memories (there are a lot of repeaters and stuff around
here). An alphanumeric
display for the memory channels would be nice, though not entirely
necessary. I really
want to be able to see where the VFO is on both bands, too. Reduces button pushes, which
is one of my watchwords for
simplicity.
Another perusal of the Internet stores reveals a wide
variety of choices. At
first blush, I'm attracted to the following
radios:
| Alinco
|
DR620T
|
$339.99 |
| Alinco
|
DR635T |
$369.99 |
| Icom
|
IC2720H
|
$399.99 |
| Kenwood |
TMV708A
|
$399.99 |
| Yaesu
|
FT8800R
|
$389.99 |
Tough choices, since there's no obvious low-price
leader, but let's take them in order.
The Alinco DR620T is a fine radio, and is priced
attractively. It has
both bands visible in the display, lots of memories, and also sports
three different output power levels. I like this last, because
unlike most amateurs I always adhere to using the lowest power
needed to maintain reliable communications. It doesn't have a standard
on-board packet TNC, though it is available optionally for another
$130.
The DR635T from Alinco is basically the same radio as
the first, with the addition of cross-band repeat
functionality.
Unneccessary for my home station, though something to think
about for the mobile.
You never know.
But it's right out for
home.
The Icom IC2720H has everything the Alinco units have,
with the addition of seperate knobs and buttons for each band. It also sports a built-in
packet TNC supporting up to 9600 baud, plus more memories than the
Alinco units. It also
has crossband repeat.
Kenwood's TMV708A looks nice, but I can't find
detailed information for it on either retailer or manufacturer's
websites. So it's
out. (What's with Kenwood,
anyway?!)
As for Yaesu's FT8800R, it has a host of features
included in the base price, like simultaneous monitoring of the
other band. Each band has its own volume and squelch controls right
on the face, and you get more than 1000(!) memories. Plus AES is offering the
remote-head mounting kit for free. It doesn't have a TNC built
in like the Icom, though.
Now, the decision. I think the Yaesu wins for
massive amounts of features at a reasonable price, and AES for
throwing in a free widget.
But let's look at it through the prism of my
requirements. I don't
need to remotely mount the control head, so that makes no difference
(though it might for the mobile!). Taking everything into
consideration, it looks like I'm getting another
Icom.
