Yaesu G-2800DXA Extra Heavy-Duty Rotator Systems
Yaesu G-2800DXA Extra Heavy-Duty Rotator Systems are azimuth positioners designed to rotate large tower-mounted amateur and professional antenna arrays under remote control from the station's operating position. These systems feature attractive compass-dial position indication controllers, with a connector port for optional computer interface for automated directional antenna positioning control. Yaesu's G-2800DXA rotator design utilizes 98 heavy 3/8 in. dual-stacked circumferential ball bearings to distribute load over the full diameter of the housing. This design minimizes stress and wear and practically eliminates the possibility of destructive water entry: There is no shaft hole in the top of the housing. Instead of the usual AC motor drive used in older rotator designs, the G-2800DXA, G-1000DXA and G-800DXA use a variable-voltage DC motor, removing the need for a large starting capacitor with its potential for failure exposed to outside temperature variations. The factory-lubricated rotator unit is housed in melamine resin-coated die-cast aluminum, intended to provide maintenance-free operation under all climatic conditions. A mast alignment gauge on the rotator housing simplifies accurate mechanical alignment during installation. Tower mounted, this model handles over 30 sq. ft. of antenna wind load and over 650 lbs. of vertical mast load. About 130 ft. of control cable is included with the G-2800DXA only. Control console power is 110/120 volts AC. The handsome desktop controller provides 360 degrees radial indication of actual antenna azimuth bearing. You can select rotation time over 360 degrees from 50 to 120 seconds on the G-2800DXA, and preset a desired heading for the rotator, to which it then turns automatically. When a fast rotation speed is selected, special "auto slow-start" and "auto slow-stop" features avoid sharp jolts to the antenna array and tower. Activating the rotator causes it to begin turning at slow, but increasing, speed. As the antenna approaches the desired heading, the rotation automatically slows down, before bringing the antenna to a gentle stop. The operator may select the stop heading, the compass bearing through which the rotator cannot be turned, which is most convenient for their station location and operation, allowing full rotation through north, south or both, if desired. In any case, 90 degrees overlapping rotation allows rotation through the selected stop heading for 450 degrees of total rotation. These rotators are intended for mounting to an accessory shelf inside a support tower (not supplied), at least 1-meter (40 in.) below the top of the tower. Yaesu rotators have a fine reputation within the Amateur Radio community. When installing a new tower, or replacing an old rotator, consider purchasing a Yaesu G-2800DXA Extra Heavy-Duty Rotator System from DX Engineering.

Yaesu FTDX10 Compact HF/50 MHz 100W SDR Transceivers
The exciting Yaesu FTDX10 Compact HF/50 MHz 100 W SDR Transceiver utilizes the Yaesu Hybrid SDR configuration - Narrow Band SDR and Direct Sampling SDR - like the FTDX101 series. The Narrow band SDR receiver emphasizes excellent receiver performance, while the Direct Sampling SDR provides a Digital Processing Real-Time Spectrum Scope. This stylish and well equipped model sets a new performance standard for the "affordable class" transceiver. Great for base and portable operations, the Yaesu FTDX10 is ready to order from DX Engineering. Click "More Details" for Features and Specifications Main Features of the Yaesu FTDX10 Compact HF/50 MHz 100W SDR Transceiver: - Narrow Band SDR with 3 types of roofing filters and phenomenal multi-signal receiving characteristics, as in the FTDX-101 series. The Down Conversion type receiver configuration with the first IF at 9 MHz has been adopted for the FTdx10. Excellent narrow bandwidth crystal roofing filters have the desired sharp "cliff edge" shape factor. Thanks to the Narrow Band SDR's latest circuit configuration including 500 Hz, 3 kHz and 12 kHz roofing filters and low-noise oscillator, the RMDR (Reciprocal Mixing Dynamic Range) reaches 116 dB or more, the close-in BDR (Blocking Dynamic Range) reaches 141 dB or more and 3rd IMDR (third-order Intermodulation Dynamic Range) reaches 109 dB or more in the 14 MHz band at 2 kHz separation. - 250MHz HRDDS (High Resolution Direct Digital Synthesizer) affords quiet and clear reception The local circuit of the new FTdx10 uses 250MHz HRDDS method same as the FTdx-101 series. Thanks to its characteristics that improve the C/N (carrier to noise) ratio and the careful selection of components in the design, the phase noise characteristic of the local signal achieves an excellent value of -145 dB or less in 14 MHz at 2 kHz separation. - 3DSS (3-Dimensional Spectrum Stream) on the 5-inch Full-Color TFT Display with Touch-Panel functionality The 5-inch Full-Color panel shows the 3DSS display. By touching the frequency display, the numeric keypad is displayed and the active band and frequency adjustment can be set by direct input. Frequency setting and adjustment can also be performed by turning the MAIN dial or touching the scope display. Similar to the FTdx-101 series, the MULTI display, RX operation status display, Center, FIX and Cursor modes are available. - Front Panel Designed for Superior Operating Efficiency - MPVD (Multi-Purpose VFO Outer Dial), is a large multi-purpose ring around the outside of the VFO dial that enables control of Clarifier, C/S (custom selection function) and recall of memory channels. - Remote Operation with optional LAN unit (SCU-LAN10) is possible with the optional SCU-LAN10 and SCU-LAN10 Network Remote Control Software. In addition to controlling the transceiver basic operations, the versatile scope displays enable sophisticated operations such as monitoring the band conditions on a large display at a location away from the ham shack by connection to a home LAN network. Additional features of the compact Yaesu FTDX10 include: - 15 separate band pass filters - Effective QRM rejection with the IF DSP (IF SHIFT/WIDTH, IF NOTCH DNF, DNR, CONTOUR) - High-quality and super stable final amplifier utilizing the new push-pull MOSFET RD70HUP2 - Aluminum Heat Sink with 80 mm low-noise axial flow cooling fan - High Speed Automatic Antenna Tuner with a large capacity 100-channel memory - RF & AF Transmit Monitor - Microphone Amplifier with Three-stage parametric Equalizer (SSB/ AM mode) - QMB (Quick Memory Bank) - Band Stack Function - Optional speaker – SP-30 designed for the new FTDX10 - Optional 300 Hz Plug-In Roofing Filter– XF-130CN
