The standard packaging for an SG-2000, the cardboard box and packing materials, should be retained for future use should the radio need to be shipped elsewhere. The SGC Building, 13737 S.E. 26th St. Bellevue, WA. 98005 USA ©1995, SGC, Inc.
Page 16 LCD may be removed with Plexiglas™ cleaner such as is used to clean aircraft windows. The SG-2000 should be closely inspected upon arrival. As the units leave the SGC factory, they are in perfect operating condition. Should you notice any bent sheet metal, or flecks of paint in the shipping box, you may assume that the radio has taken a hard shock somewhere in shipping.

This was done after a careful study of emerging HF radio technology in the military and government sector and with an eye to providing the users of SGC equipment with the highest level of flexibility, not only today but in the future as well.

In the control heads, the audio signal is further amplified and processed. A syllabic squelch circuit (which was pioneered by SGC in 1976) is used to turn off the noise coming out of the speaker in the event that a signal is not being received.
Page 22: Control Circuits
This means that the control head may be placed as much as 50 meters away from the radio. Although not supported by SGC, many users of the control heads have reported success at longer distances. As with all SGC specifications, 50 meters is a conservative number.

10-conductor control cable between our radios and remote heads rather than a fiber optic cable is one example. SGC has learned that while fiber optics are an excellent material, they are not easily reparable in the middle of the desert or ocean.

Page 42: Remote Head Cable Extension
Carefully unplug the existing cable assembly from the control head and radio and replace it with the desired length. While we recommend that you use the control head wiring supplied by SGC, you may use any other 10-conductor shielded wiring. Remember, however, that the length of the cable run to a remote head is partly determined by the quality of wiring used.
Page 43: 10.0 Power Supplies
The longer the distance between a power supply and a radio, the greater the voltage drop will be. SGC recommends placing a power supply no more than 25 feet from a radio. There are two reasons for this: First.

SGC does not generally recommend switching type power supplies in either a mobile or a base station installation for these two reasons: first, switching power supplies easily generate noise from the switching circuitry;...
Page 45: Mobile Power Supplies
First, HF takes a lot of power on transmit. While you can use a single battery to power both the vehicle and the radio, SGC recommends the installation of an additional battery in all cases where this is practical. The reason for this is that the output voltage from a battery drops as the load increases.

Page 51: Antenna Couplers
HF radio controllers. So SGC began to build computer controlled antenna couplers including the SG-230 and SG-235 Smartuner™ couplers. SGC began building the servo-motor type automatic couplers in 1975 so the transition to a computerized coupler with extremely fast retune times was a logical development.

1.8 to 30 MHz. SGC is the only manufacturer to add the good attributes of a 108" whip (which performs well at the 20 MHz range and above) with the high performance of a helical antenna that performs well at the lower frequencies.
Page 53: Unconventional Mobile Antennas
QMS mounts without drilling any holes in your vehicle. That's a major advantage at vehicle trade-in time. So, if you're planning to use HF while mobile, SGC's QMS system is the best solution you'll find. Contact your SGC dealer or call SGC direct.

The most common configuration of the SG-2000 in the marine environment is use of a standard mounting tray (SGC Part Number 52-46) and the remote head kit (SGC Part Number 04-12). With the control head detached from the body of the radio, the operating position may be made much more compact.
Page 99 SG-2000 MANUAL SGC does not endorse the use of artificial ground plates as a replacement for an adequate bonding system. While such plates, generally made out of a porous zinc alloy, provide some grounding, they are also subject to corrosion and marine growth which reduces their efficiency.

22.2 Scanning in One Direction Only SGC has received several technical support calls inquiring about the radio scanning only in a single direction. In these cases, the radio is reported to be scanning in only one direction toward a certain frequency. If the radio is set to a low frequency, it may only scan upward toward a higher frequency.

It is highly recommended, however, that any SG-2000 with board-level problems be sent back to SGC Inc or to an authorized dealer for repair. For testing purposes the SG-2000 is broken down to four subassemblies: Exciter, LPA, Head and Main CPU (treated as one), and the Display subassembly.
