The important parts of my radio station are shown in their own sections, though I suppose that what is important is open to interpretation. What is generally meant by using the term important, is expensive, complex, and troublesome. The accessories, and add on components which are used to compliment the function of the "important" gear are often equally vital to the operation of the station. Without a power supply, or microphone,  a station is as dead as if there were no transceiver. Still, most of these items are collectively known as accessories.

Power supply
    Without a power supply, most ham equipment can not be used for base operations. Nearly all amateur gear is designed to run on 13.8 volt power. Military and commercial gear runs on a variety of voltages from 6 to 28 volts DC. Most transceiver models have matching power supplies produced for them. This has the advantage of guarantying that the supply will be sufficient for the needs of the unit, and that all cables, and connectors match. These supplies will also be designed to match the styling of the radios for which they are built. The only drawback, is that they are generally the most expensive route; but for the ham who wishes to go first class, this is the way to go.
    In my own case I picked up a lab power supply. This is a 42 amp unit, which gives it quite an advantage over the Kenwood unit, designed for my rig (the Kenwood unit puts out 30 amps). Of course, it does not feature the Kenwood logo, nor does it match the styling of my radio. Oh well, you can't have everything. The unit has multiple taps, for powering a variety of gear, and has more than enough power to run several pieces of gear at once, including more than one radio at a time. Something that may turn out to be an advantage at some future date, is the ability to wire the unit for several different voltages. This is done easily by simply connecting the power feed to different combinations of terminals. This presumably will give me the ability to operate military and commercial gear on 14, 28, 60 and whatever other voltages are out there. It is also possible to operate units on different voltages concurrently. As a lab power supply, I assume that the current supplied is clean, and pure.
Antenna Tuner
    This is very nearly indispensable, for the operator of most of today's multi band HF transceivers. The alternative is to have a series of antennas cut to length for different bands. Of course, these would then require an antenna switch to select the proper antenna for the band being used. The operation of a single band unit, like most of today's VHF/UHF transceivers, should not require a tuner with a proper antenna, as the antenna will be adjusted once, during installation, and then left alone. While there are certainly performance advantages to having a properly tuned antenna, or connecting through a tuner, the main reason for tuning is to prevent the reflected waves, generated by high SWR, from frying the finals of the transmitter. Many transceivers have fuses or circuits which protect against this, but none are fail safe.
    A number of today's transceivers are available with built in antenna tuners. My own Kenwood TS-440SAT is so equipped. These are automatic tuners, and you can hear them churning away , when you set the unit to tune. Most use little motors to turn variable capacitors, or coils, until a proper match is established. These units are very convenient, particularly when built into the radio, but do not do a better job than a basic manual tuner. In some cases, as with random wire antennas, or oddly designed, low bandwidth antennas, the manual tuner can do a better job, or may even be the only way to get a match.
    The tuner built into my Kenwood will not tune for 160 meters, and requires a 50 ohm impedance from the antenna/cable combination, making it unable to tune random length wire antennas, or unbalanced antennas. It also had a bit of a hard time tuning my Cliff Dweller antenna on certain (30, 17, and 12 meter) bands. It is rated to tune for a resistive impedance of between 20 and 150 ohms. The tuner should not be used for more than 30 seconds at a time, according to Kenwood, and three unsuccessful attempts indicate that the tuner is not compatible with a given antenna system, on a given band. The tuner sits in the right hand side of the transceiver, and is standard on the TS-440SAT, and on option on the TS-440, and the TS-440S. I eventually bit the bullet, and got myself an external manual antenna tuner to compliment my auto tuner.
    The manual tuner I picked up, is a Kenwood AT-200. This model was designed to accompany the older, TS-520 transceiver. The styling is close enough to mach that of my TS-440 nicely. The tuner has connections for three antennas, including a wire. There is also a connection for a dummy load. In addition to it's tuner, and SWR meter, the T-200 can be used as a power meter. It will tune through all of the bands from 160 meters, up to 10 meters. Besides the tuning knobs, there are selector switches for band preselection, as well as for selection of the antenna. The meter is switchable for a maximum power reading of 20 or 200 watts.
    All in all, this is a very nice unit, and gives me a flexibility in antenna design, and selection, which the auto tuner did not offer. I am looking forward to trying it out with some homebrew EH antennas, and a long wire. I may try my hand at a few other types of antenna construction, and a bit of experimentation. Resourceful ham operators have used tuners to create resonance in all sorts of objects, making nearly anything metallic into a potential antenna. In some cases, the performance is surprisingly good. At any rate, possession of a good antenna tuner, will assure me of reasonable antenna performance, no matter what the local restrictions on type, and construction may be. This in combination with the ability to use a longwire, may very well constitute the potential for the ultimate stealth antenna.

Microphones
    As with the power requirements, most amateurs will find their units coming with a microphone more suited to mobile operation than to use as a base. This is a matter of taste, of course, and there are many who will find the standard, basic, handheld mike perfectly satisfactory for home use; others will wish to purchase a desk mike, or perhaps a headset. The main advantage to a desk mike, is that it frees up the hands, though most models have other advantages, and offer additional  features.
    My particular model was made by Kenwood, and is one of the more deluxe desk microphones on the market. It is the model MC-85. This unit has a little control panel of it's own, and is specifically designed to integrate with the Kenwood series of radios. Connection through the standard Kenwood 8 pin plug gives the unit the capability to change frequencies, via a switch on the mike panel. There are plugs on the back of the unit base for connecting up to three radios, though the unit was only provided with one cable. Buttons on the mike panel select between the three outputs. In addition, there are slider switches to adjust pre amp, and compression levels. A two position switch turns compression on and off. There is also a meter to indicate the microphone output level. A tone switch, PTT, and PTT lock complete the controls. A pair of LEDs, indicate power, and PTT lock. The unit is battery operated. The actual microphone element is an electret condenser unit on an adjustable goose neck mount. The styling of the unit is classic seventies/eighties, and it is one of the more elaborate desk microphones on the market.

     The microphone is powered by many Kenwood radios,, and has a battery box for use with radios which are not compatible with powering this mike. Extra cables can be purchased for connecting for up to three radios. The supplied PG-4G 8 cable is the standard connection for most Kenwood radios. 4 pin (PG-4D) and 6 pin (PG-4E) cables are also available, though they will require installation of 4 AA batteries, in a small compartment under the mike, accessible by removing a pair of screws. This is a 700 ohm mike with a 300 to 7000 Hz frequency response. Some users have reported that this mike insensitive to RF interference, when running multiple radios; but I have had no such problems. Reports form other users indicate that unit should be checked for proper ground, and for improper insulation between the mike element, and the gooseneck.
Key
    Considered as an obsolete holdover from past days, a rite of passage for new hams to get on the international bands, a burdensome requirement, or the mark of a true radio enthusiast, CW (Carrier Wave) operation is assumed to be a capability of any good fixed base operation. For a long time, this was the real sticking point to my entry into ham radio. My code skills are dismal (some would go so far as to say that they are non-existent). I therefore do not have a very elaborate key; but then, how elaborate could something like a telegraph key get? It would seem that picking a key would be an easy thing. We all know what they look like, from war movies, cowboy movies, and adventure shows. We all know how they work too. You simply tap out the dots and dashes on them, to be translated by the listener on the other end. Of course, nothing that attracts any sort of hobby or recreational user ever stays simple. There are a variety of keys, and code generating devices out on the market; what most of us picture is the straight key.

     In the early days of ham radio, and for decades beforehand for generations of telegraphers, long distance communication meant sending code, via key. For telegraph operators, an entire eight to ten to twelve hour work day might be spent sending code. After some years of this, telegraph operators would develop what was known as Glass Arm.  This appears to have been some sort of carpal tunnel syndrome. The culprit was the constant wearing repetition of movement, over long periods of time. In order to combat this, a new type of telegraph key was developed in the 1880s, called the Sideswiper, also known as the Cootie.
     The Cootie worked by flipping the paddle from side to side, instead of straight down. Rather than placing your fingers on top and tapping down, the Cootie worked by grasping it sideways, the same way that you hold a housekey before turning it in a lock. You then formed dots and dashes by rocking the key from side to side. For some reason, probably known to orthopedists, and anatomists, this is much easier on the arm and joints. It could also be quite a bit faster, as characters could be formed on the backstroke. The Cootie had contacts on both sides of its travel, so that a dot or a dash could be made by rocking the paddle in either direction. The Cootie was in popular use until the 1920s, when it was replaced with something more advanced, called the Bug.
     Technically know as the Vibroplex, the bug was a sideswiper, just like the Cootie; but it was a bit more automated. Where the Cootie could send either a dot or a dash, from either direction, the bug made a dot when pressed to the right by the thumb, and a dash when pressed to the left by the forefinger. This really took some getting used to but could be quite fast once mastered, and always sent perfectly formed characters.
        During the seventies and eighties, automation, and emerging digital electronics made it possible to use memory keyers. Generally, these were used along with a regular key, and would remember certain letter combinations, like the station's call sign. Eventually, availability of fairly powerful computers made it possible to send code vial a computer keyboard, and to have it decoded by computer and displayed on a screen.

Computers and software (C)
    Computers are nearly indispensable in everything today, having crept into most human activities over the years. Ham radio is no exception. I go into a bit more detail in my section on Porky the computer; but have not yet been able to do the subject justice, and do hope to expand on this subject in the future.
External speaker/phones
    Even the most basic, primitive units have built in speakers. The problem is that these are often basic, primitive speakers. Companion speakers are made for most transceivers, and many hams use headphones.
Clock or clock software.
    FCC regulations require a station to be identified at regular intervals. It helps to have a clock with a timer, to insure compliance. Actually, a clock is a great accessory, in any case. They are helpful in logging contacts, keeping up with nets, and even occasionally for telling the time. Back in the old days, radio manufacturers sold station consoles with clocks, timers, SWR meters, and other features built in. Today we use computer clock software, or radio controlled atomic clocks.

    Assuming that you have gathered all of the gear that you need, or at least all that you can afford, you need a place to operate from. Many ham stations operate out of a small corner of a bedroom or living room, others are housed in elaborate shacks. My first two stations were simply stacked on a desk, while many operators use bookshelves or other style shelving units. Whatever the means of the operator, all fixed base stations must be arranged with the following considerations:

• proper presentation, and ergonomics

• room for everything

• nice appearance

• proper cooling

• connections for power, ground, and antenna

• good lighting
