In front of the YO is a Samsung Sens notebook computer. Just right of the desk is the Wyse Model 75 monitor for the packet cluster system. This sits on top of a home brew linear amplifier. The unit in front of the radio is a Sony MZ-R55 minidisk recorder. Its small size, which I thought would be a problem, turned out to be advantageous.
As you can see, the recorder is attached to my audio rack via about five 5 feet of double shielded cable. When not in use, it stores nicely under the radio, cables and all! My current audio equipment. Starting from the top; Behringer Mic Behringer EX Behringer DSP The forward gain is high for this short boom length which results in a low feed impedance and limited SWR bandwidth than a looser coupled beam.
Great low angle takeoff because of its height. The 2mtr antenna is a Hustler G7 antenna with 7dBd gain. All antennas are mounted on unique coax standoffs which, while holding the coax, serve as antenna mounts at each tower section. Besides holding the tower, this allows for easy leveling of the overall structure.
The five 5 section tower sits on a trust bearing supplied with grease fittings in order to keep rotational wear to a minimum. The bottom plate supports most popular rotators. The tower system was purchased with the positive pull-down feature. This feature is very desirable during high winds. With all this power, it breaks tangled coax or anything else without hesitation!
Unfortunately this has happened at least once! The upper spring and pulley assembly takes up slack in the positive pull-down cable that goes directly to a tie point on top of the tower.
The tower is controlled by two 2 limit switches that set the highest and lowest points before the motor power is cut off. The control box is basically a junction box for Vac and contains reversing and limit switch wiring.
Thus the total dissipation is kept remarkably low and, even more important, the heat buildup in the studio. This is my main amplifier. Incidently, the baffles soften the air noise pickup in the mic. The baby blocks remind me of my name during senior moments!
This home brew amp is a floor unit that houses a single Eimac tube. The inset bezels are backlighted and emit a soft red glow in a darkened room. The top hinges to reveal a massive power supply with 86uF of capacitance and Volts. It outputs watts with 60 watts drive. I do not use this amp because, unlike the AL, it takes 5 minutes before the filament interlock is ready. I did this to minimize the chance of a filament to cathode short!
The tube is 25 years old! A tube preamp in general gives a warmer sound to the audio from the mic. Programs are stored in 10 user modifiable programs.
A truly marvellous dynamics unit in one increment of panel height. The Alesis MV III generates pro digital reverberation effects using bit linear PCM processing which includes reverbs, 96 delays, and 16 special effects as well as two band frequency equalization. There are as many opinions as there are mics, so here we all tend to get subjective.
These mics produce audio with little or no coloration. The Marshall MXL is a quality condenser microphone that is reasonably priced. Links to Sites.
