Yaesu FTDX-9000 HF/50Mhz

ft9000_frontThe FTDX-9000 is a ground breaking HF/50 MHz Elite Class Transceiver from the YAESU Engineering Team. Previewed at the Dayton Hamvention® in May, 2004, the FTDX-9000 features unmatched close-in dynamic range, flexible selectivity choices due to its advanced 32-bit DSP filtering, a high-resolution TFT display, and high power: the 200-Watt “D” (Deluxe, fully equipped) and “Contest” (custom configurable) versions, as well as the 400-Watt “MP” version, are all available now!

Now includes additional features of PEP9000-Performance Enhancement Program

Advanced 32-Bit IF DSP
The FT DX 9000 utilizes a 32-bit floating-point IF Digital Signal Processing system to provide a wide range of interference-suppression and intelligence-recovery features. Included are Variable IF Bandwidth with preset “Narrow” settings, IF Shift, Digital Noise Reduction, and a Parametric Equalizer “Contour” system for enhancing or suppressing sections of the IF passband. On transmit, the bandwidth is adjustable, and the SSB voice parameters may be precisely adjusted using the Three-Band Parametric Equalizer system.
200 Watt and 400 Watt Versions
The FT DX 9000 “D” and “Contest” versions provide 200 Watts of power output, with an internal power supply, while the FT DX 9000MP provides a whopping 400 Watts of power output (the power supply is external on this model). All versions provide continuous adjustment of the PA Bias Level from the front panel, with real-time metering of the bias level and heat sink temperature, for adjustment of the operating conditions between Class AB and Class A. Class A output on the MP version is 100 Watts, while it is 75 Watts on the D and Contest versions during Class A use.
YAESU Exclusive: Full Duplex (for One-Radio SO2R Operation!)
The FT DX 9000 is the only Amateur HF Transceiver to provide Full Duplex capability when operating on two different bands. So, in a contest, you can be calling CQ on 10 meters while simultaneously receiving on 20 meters, looking for new multipliers! This unique capability is found only on the FT DX 9000!
Large (6.5-inch) Multi-function TFT Display
The FT DX 9000D’s 6.5″ TFT display provides a host of operating status and station-management information. Included are a World Map with Sunrise/Sunset/Grey Line display, Logbook, Swept SWR across the band, PA Bias Level, PA Heat Sink Temperature, PA Voltage, Real-Time SWR, Memory Channel listing, Menu listing, and (when using YAESU rotators) indication of the rotation direction and rotation speed, along with presets. A responsive, high-resolution Spectrum Scope lets you watch activity on the band, with custom span and center frequency presets available via the Menu. And, on the rotator page, use your keyboard (not supplied) to input your Latitude and Longitude, and the FT DX 9000 will draw a Great Circle Map of the world, centered on your location! There’s also an “Oscilloscope” page, showing TX/RX waveforms as well s a “waterfall” display for weak-signal digital work.
Three Roofing Filters for Outstanding Close-In Dynamic Range
The FT DX 9000 provides three “Roofing” filters in the first IF, allowing you to select (on the fly, or automatically by mode) front-end bandwidths of 15 kHz, 6 kHz, or 3 kHz. Choose the bandwidth that best matches the band occupancy and your operating mode at the time!
Leading-Edge Receiver Performance
The receivers in the FT DX 9000 are crafted using an ultra-quiet 400 Mhz High-Resolution DDS local oscillator, for extraordinarily low noise close to the carrier. The high-level mixers and robust IF amplifier stages are designed to yield a 3rd-order Intercept Point in excess of +40 dBm, your assurance of high performance on today’s crowded bands.
Parametric Microphone Audio Equalizer
Another unique FT DX 9000 feature is the 3-band Parametric Microphone Equalizer, independently adjustable for the front panel (XLR) and rear panel (8-pin round) microphone connectors!

The Parametric Equalizer system allows the operator to tailor the transmit passband more precisely than with other equalizer systems. You can adjust the center frequency of each of the three audio passbands, the width of each of these bands, and the amount of boost or suppression you wish to engage within each of these frequency ranges. This allows you to focus available power where you want it, and maximize fidelity according to your voice pattern and the response of your microphone.

And because you can adjust the front and rear microphone jacks independently, you can equalize one way for a “DX” mic element on the rear panel, and equalize differently for a “studio” microphone on the front panel mic jack!

Kenwood TS-590SG HF/6m Base Station

Kenwood TS-590SG HF/6m Base Station

The Kenwood® TS-590S provides impressive, yet affordable amateur operation on the HF and 6 meter bands. Thanks to a down-conversion receiver, narrow first roofing filter and dedicated first mixer, the TS-590S has the best dynamic range in its class when handling unwanted adjacent off-frequency signals¹. Having the first roofing filter (6 kHz BW) directly after the mixer enhances the noise blanker’s ability to deal with adjacent off-frequency signals. The result is excellent receive performance, revealing signals that would be hidden to lesser rigs.

Kenwood was the first in the amateur radio market to deploy DSP based AGC at the IF stage with the TS-870S. This DSP technology has now been taken to the next level with the TS-590S. With this new transceiver, a 32-bit DSP is deployed from the IF stage forward, the TS-590S marks a bold new chapter in Kenwood’s proud history of making compact, high-performance transceivers. The DSP based AGC has been improved for the target signal in the IF passband, this result is greatly improved in-band IMD characteristics that are on par with those “top of the line” transceivers costing much more¹ (¹for 160/80/40/20/15 CW/SSB/FSK).

The TS-590S transmit section uses a die-cast aluminum chassis combined with a large heat-sink to increase heat dissipation efficiency. The cooling system uses the same size fan as in the previous model, but now uses two of them. This allows the fans to run at a much lower RPM while still providing more airflow. Lower RPM means less noise. This heavy-duty TX design is capable of withstanding long hours of operation under grueling conditions as found on DX-peditions or during contests. Excellent performance is expected, combined with ergonomic operation.
