The new TS-590SG is the great novelty by Kenwood for 2014. This transceiver comes to relieve the Kenwood TS-590S, preserving most of their features, incorporates new functionalities and a great improvement in transmission and reception.
The new TS-590SG keeps the most of the key features of its predecessor TS-590S. Among the improvements stands out an improved reception and transmission.
Kenwood launches its new All Mode HF / 50MHz Transceiver with optimum performance on RX to satisfy a wide kind of users from beginners to DX experts to totally enjoy the amateur radio.
The price only includes the Kenwood TS-590SG transceiver.
Superb benefits on RX: Excellent Dynamic Range
In the 15, 20, 40, 80 or 160 meters bands, the TS-590SG uses a lower conversion for the first IF (11.374MHz). Counting with the first directly Roofing filter (6 kHz bandwidth) after the mixer to improve noise reduction ability for adjacent signals outside our frequency.
What really determines the RX benefits is the second Roofing filter, after amplifying. The TS-590SG is equipped with 500Hz and 2.7kHz MCF 6 pole filters. Achieving with that a superb dynamic range when there are adjacent signals, a feature that was not possible when using a higher conversion. When the interfering signal was close to working signal, a virtual plane dynamic range is maintained. With strong interfering signals, the capture of the signal is clear.
DDS generates excellent feature of signal to noise ratio, significantly reducing the noise generated by adjacent unwanted signals.
For the first local oscillator, instead of using the conventional PLL / VCO, the DDS (Direct Digital Synthesizer) output is directly supplied to the mixer. When lower conversion is activated, the oscillator frequency is lower than if a superior conversion is used, the output has a better feature of signal to noise ratio and an optimal level of reciprocal mixture.
Wide range of facilities thanks to the 32-bit floating point DSP.
In addition to basic functions such as AGC, Digital IF filters, detection and demodulation, a large number of facilities including noise reduction and IF rejections are all implemented by last generation algorithms.
The TS-590SG uses a DSP from the IF level. Kenwood was the first brand offering IF AGC based on DSP in amateur equipments (TS-870) and the DSP technology has been improved in the TS-590SG, resulting in the development of an excellent IF AGC. It is possible to reach an optimal level of AGC signals even beyond the Roofing Filter and the IF passing band. You can be sure to optimally operate at any time, without having to think about the Roofing Filter bandwidth. The Gain control performance has been totally improved for the desired signal in the IF passing band (RX Band). The result is a characteristic of IMD (Intermodulation Distortion) hand in hand with the high end transceivers. Enjoy a superb RX with next-generation Kenwood sound.
Adjustable IF filter passband
This operates as the passband HI CUT/LO CUT function in SSB/AM/FM modes, and as the WIDTH/SHIFT control function in CW/FSK/SSB-DATA modes. Operation can be switched using the menu in SSB and SSB-DATA modes.
Remove a powerful interfering signal with a notch filter to capture a weak target signal. Choose from automatically variable notch frequency in IF Auto-Notch(1) and manually adjustable notch frequency in Manual Notch(2) depending on your interference situation.
One-touch A/B switching FIL A/B can be set independently with VFO A/B. This convenient function enables swift operation during contests or split operation.
In addition to the analogue noise blanker (NB1), which has a proven track record for eliminating weak noise, this transceiver is equipped with a digital noise blanker (NB2). The optimum blanker for the type of noise and reception conditions can be selected. NB1 enables stable noise suppression independent of reception bandwidth, while NB2 is effective against noise that defies tracking by an analogue noise blanker.
Highly reliable design guarantees stable operation
A pair of 60mm×60mm fans have been used for the cooling system, which provides sufficient air flow at low rpm for less noise. Attention has been paid not only to the fans and motors but also to the size and shape of the intake/exhaust vents as a comprehensive approach to quieter operation. The aluminum die-cast chassis is combined with a large heat sink to effectively dissipate heat, minimising the rise in temperature in the final section during continuous transmission sessions. This heavy-duty design is capable of withstanding grueling conditions typical of contests or long hours of hard operation.
Built-in high-speed automatic antenna tuner
The built-in preset-type automatic antenna tuner covers amateur bands in the 160~6m band range and can operate when the transceiver is receiving. High-speed operation and the proven relay method enable rapid QSY through instantaneous band changing.
Drive output (including 135 kHz band)
The transceiver comes equipped with a drive output (DRV) connector that enables external access to the transmission drive output (approx. 0 dBm). This is not just convenient when a transverter is attached; this DRV connector can also be put to use for transmission on the 135 kHz band, for which the main antenna terminal cannot be used. Performance can be further enhanced when combined with a dedicated reception antenna connector.
The speech processor increases the clarity of messages for the receiving station by raising average transmission modulation. Besides adjusting compression level, soft and hard modes are available for 2-level adjustment. Compression levels can be set for each of mic transmission and voice-message transmission.
The TX filter passband is switchable. Low-pass and high-pass cut-offs can be switched independently for fine control over filter operation.
The equaliser enables the adjustment of frequency characteristics to suit the voice quality and microphone characteristics on the transmitting end. Users can choose from flat (default), high boost (2 types), Formant pass, and bass boost (2 types), as well as conventional and user settings (using the ARCP-590G).
The transmission monitor function outputs transmission audio via the speaker in 20 steps, allowing you to check sound quality.
- VOX function (adjustable gain, selectable delay time)
- Adjustable TX power output
- Adjustable MIC gain
- Adjustable CAR level
Diverse functions supporting CW operation.
In addition to conventional split frequency setting methods, the TS-990's proven split setting functionality has been included. A long press of the SPLIT key, when making a 2kHz up setting, will enable quick setting by pressing "2" on the keypad. Furthermore, in simplex operation with just XIT on, the XIT frequency can be changed with TF-SET. The keypad keys are now band-direct keys. Each band has 3 memories, enabling quick call-up of usually-used frequencies.
Note: Delays may occur when using USB audio. We recommend using USB audio in situations where time lag is not an issue.
Using the ARCP-590G (radio control program), virtually all functions can be controlled via a computer. Changing various function settings and managing memory channels can all be done from your PC. The ARCP-590G also enables the recording and erasure of voice messages.
Voice guide and recording functions (option)
VGS-1:Voice guide and storage unit enables voice guidance for frequency, key operation, settings, etc., and recording/playback of messages. A Manual Mode, in which vocalization takes place only when buttons are pressed, has been added to the voice guidance. Either English or Japanese can be selected for the voice guidance language.
-Constant receiver recording: 30 seconds. (1 channel)
Easy-to-use, diverse memory functions
The transceiver features a memory that can store up to 120*1 frequency memory channels, with each able to be given a memory name of up to 8 letters. Also included are the memory scroll function, which can be used to check memory data without changing operating frequency, memory channel copy, which enables the copying of memory data to another channel, single channel memory clear, memory lockout, memory shift, and the ability to change memory data/frequency temporarily. Other features include the Quick Memory function, which can store up to 10 channels*2 on the fly, and the capacity for temporary changes to memory shift and memory data.
*1: Including specified range memory and expanded memory channels.
*2: 3, 5 or 10 channels can be selected.
Multiple scan functions
Program scan, memory scan, group scan, subtone scan and CTCSS scan are included among the many scan functions available. The transceiver also offers program slow scan, which automatically reduces the scanning speed around any frequency of special interest.
Enables full-duplex operation with improved functionality such as visual confirmation of HF frequency on the LCD panel. Control via TNC (AX.25) enables more access to HF functions: XIT, mode switching, split-frequency operations on/off, memory shift, and frequency step selection. The transporter sends out its pre-programmed call sign via CW every 10 minutes.
