Goes up to HF only. Great sensitivity specs on paper; however, the sensitivity is measured under non-standard conditions. Has remote control. Might be hard to use if remote control is broken. Must specify Hz CW filter at purchase time if you want filter. Menus, menus, and more menus. Designed for high-signal strength areas like Europe. Minimum tuning increment is 2. No DSP. No BFO knob. This coupled with excellent selectivity make the AR a strong choice for the shortwave broadcast listener or DXer. Although performance is excellent, features have not been forgotten. The mini headphone jack will accept a mono or stereo 3.

The two line 48 character backlit LCD gives you the status of the receiver. The supplied full-featured 32 button infra-red remote provides access to virtually all facilities including: volume, tone, numeric keypad, memories, PBT, filter selection, etc. Made in England. Includes VAC wall transformer. The optional BP allows portable operation. Note: The sensitivity quoted by manufacturer is measured using non-standard conditions. AGC off. Physical: 9. Figures in brackets indicate R F pre-amp switched on. There are a number of improvements in the new version.

The receiver continues the British trend for producing high-quality receivers without frills at reasonable prices. Remote control keypad enabling direct frequency entry. Antenna connectors are two: 50 Ohms and Ohms unbalanced input for wire antennas. Four IF filters with the option to add two additional filters. Two VFOs. Computer control.

The user must 'drill down' to find settings and options. It is quite different than the Japan Radio Company NRD-series receivers that have almost every function on a separate knob or switch.

Our listener feedback suggests the menu structure approach is a 'love-hate' relationship with few users in the middle ground. The AR was an excellent receiver for the price, especially in Europe. Should you wish to add the hardware noise blanker and audio notch filter, order the UPNB slight saving in price. Japan Radio Corp. Old model. JRC www. Compared to analog signal processing circuits, digital signal processors are more advantageous: They only require less precise components; they are robust against drift and interference; they are easier to integrate with high precision; and they offer greater flexibility with software processing.

The digital signal processing algorithm is based on repetition of operations such as data readout from the memory, multiplication, addition and subtraction. See your information on screen! Covers from 0. And the adopted external DC IN terminal allows you to operate with 3.

In addition, the installed BP can be charged simultaneously, while 5. Not only can you see your operation status, you can display broadcast visual information. You can watch TV programs at anytime, anywhere. Great for sporting events, security, or amateur TV without unpleasant wiring. Wideband receiver. Yaesus have notoriously bad user interfaces.

go here Despite its incredibly compact size, the VR provides coverage of kHz through Making operation simple and efficient is the "Auto" mode, whereby the tuning steps and operating mode are automatically programmed according to the frequency you have selected. You won't miss those quick, important transmissions with the VR When monitoring on the "main" displayed frequency, you can simultaneously listen to a second station operating within 20 MHz of the main frequency in the AM and FM-Narrow modes.

This can be especially helpful while monitoring public safety communications. Featuring a handy world map showing the station's location, the special Shortwave Broadcast Station Memory Bank includes several different frequencies from a number of popular shortwave stations, including Voice of America, the BCC, Radio Japan, Voice of Russia, etc. The operating frequencies may be changed by the owner, to keep up with changing station schedules! To aid in finding band activity, the VR's Real-Time Band Scope, used while operating in the "VFO" mode, will sweep the band in search of activity, displaying the received signals graphically according to frequency and signal strength.

The incredible channel memory capacity of the VR allows an astounding array of operating possibilities! The memories may be arrange in up to Memory Groups, and you can attach an alpha-numeric label to both Memory Channels and Memory Groups to aid in channel identification.

Drake SSR-1 Receiver

The memories store operating frequency, noise blanker status, and DSP information separately, so each channel is optimized for best reception. The VR's versatile scanning system allows lightning-fast sweeping of operating frequencies, so you won't miss any of the excitement on the bands! The scanner allows you to select from three scan-resume options, too: "Delay" Scan, which lets scanning resume after a programmed interval of waiting on an active channel; "Pause" Scan, which holds on an active channel until the incoming signal disappears; and "Hold" Scan, whereby scanning stops when activity is encountered.

There is a wide array of scanning features available to the VR user:? VFO Scan Sweeps the entire frequency range of the receiver 0. Memory Scan Choose from scanning of all memory channels, or channels within a particular memory group. As many as band-limit memories may be utilized for the setting of scanning borders. Priority Operation Allows operation on one channel while periodically watching a "Priority" channel for activity.

Operation will shift to the Priority channel if it becomes active. The optional DSP-1 Digital Signal Processing Unit includes a number of features which can significantly enhance reception through improved interference rejection. Digital Noise Reduction Filter The DSP will analyze the incoming passband and suppress noise which is not directly associated with the incoming signal, providing quieter reception. Digital Notch Filter Automatically notches out annoying "beat" signals "heterodynes" which can spoil reception, especially during Shortwave operation. Comments about the Yaesu VR from www.
