8 Automatic memory input (70 radio stations) Sony CRF-V2 1 Communication receiver is very large, which is equivalent to the volume of a 2 1 inch color TV when many accessories are integrated. The weight of the fuselage is 9.5kg (including rechargeable batteries and printing paper).

The workmanship of the shell is very good, and the colors of various buttons are also very bright. If it's not huge, it's really a pity to just look at the part. After reading it from left to right, you will feel that it is like a fully armed knight: there are two reversible base support plates at the bottom to support the receiver and tilt it at an angle. Compared with the vertical desktop, this angle is convenient for operating the control keyboard, clearly observing the display screen and taking and placing the paper tape for printing satellite cloud pictures; There is a flip cover on the back of the receiver, which hides the active rod antenna matched with the receiver. The antenna consists of two parts: the antenna base and a feed line about 8 meters long. The feeder connected to one end of the receiver has two sockets, one is an antenna socket and the other is an internal power socket (3.5mm). The antenna socket faces the front of the receiver, and there are two antenna sockets at the lower end of the right side plate, and the other one is FM/LW/MW/SW. At the lower end of the left panel is a battery compartment, which can be used to charge the battery accessory NP-22H or use an external power supply. The power supply performance of NP-22H introduced in the user manual is as follows: listening to FM can last for 5.5 hours; I printed the fax signal for three hours. I didn't test this data in practice. As a test equipment, I use its external power supply to power the receiver. Two No.5 batteries are used to store the data and clock stored in the receiver. The battery box is located under the antenna box on the back of the machine.

Below the front panel, there is a printing paper installation box for printing satellite cloud images. The model of printing paper is UPP-2 1 3P.

There is no backlight system on the screen. The front panel is illuminated by a small lamp on the left side of V2 1. When not in use, the small lamp is embedded behind the machine.

Sony SRF-V2 1 has a portable device at the top and a guard on the panel to protect the damaged keys, so as to move its listening environment. But this receiver is really too heavy, not a listening device for going out, but a desktop receiver. It can be described as "very simple operation". Although its panel is densely covered with various buttons and knobs, there are two display screens, and there are many menus and English instructions in the big display screen, its routine operation is very simple and clear.

Sony CRF-V2 1 uses "KHZ" and "MHZ" buttons to distinguish frequency and frequency band, which is very user-friendly.

When you select 6, 2, 1 and KHZ, the receiver reads the medium wave broadcast signal of AM62 1.

When you select 1, 5, 4, 3, 5 and KHZ, the receiver reads the short-wave frequency broadcast signal of SW 15435.

When you select 9, 7,., 1 and MHZ, the receiver reads the FM frequency broadcast signal of FM97. 1.

In terms of this direct input frequency, GRUNDIG YB400 and Philips AE3750 combine "KHZ" and "MHZ" into one, which is more convenient for users to use, while Sony CRF-V2 1 feels very direct after separation. Usually, when you want to listen to the broadcast in the KHZ band, you will naturally choose the "KHZ" key to let the listener feel what he wants to hear.

After selecting the listening frequency, the selection of the next receiving mode is also very simple, which can be seen at a glance by looking at my picture introduction. It directly puts the receiver in the receiving state of AM narrow/wide, FM narrow/wide, SYNC LSB/USB and SSB LSB/USB. What, you didn't see FM narrow, which means you must have missed breakfast, and your blood sugar is too low. It's at the top of those seven receiving mode buttons (FM), awesome FM, you know? The default is broadband FM reception. If you want narrowband FM reception, just press this terrible FM button. Last night, I also listened to the CQ of A900 1 transceiver at FM 29.6MHZ with V2 1, so I used this button. How's it going? That's great.

After the acceptance method is also adjusted, the next step is the storage frequency. There is a button "Memory Page" on the right side of the large display screen. Hold it down, then turn the big tuning wheel and select the number of pages, totaling 50 pages. After selecting a pre-stored page (such as page 6), press "MEMORE ENTER" in the lower right corner of the big screen with one hand, and select the key F 1-F7 at the bottom of the screen with the other hand to store the currently played radio frequency in the range of 1-7 (such as F3), so that a * * can store 50 X 7 =350 radio frequencies.

When the radio station is stored, calling out is a similar operation. Turn the page and select the radio frequency of F 1-F7, which is very simple.

The stored radio frequency is not only convenient for listening, but also provides the function of starting and printing (satellite images) at regular intervals. By selecting the "Function" function key on the right side of the screen, the "Timer" command is called up at the lower part of the screen (F5). At this point, the screen shows eight timed start-up and printing. Sony ICF-SW7600G/GR, GRUDNIG YB400, YB230 and Philips AE3750 all provide only two timed start-ups, which are not only few in number, but also without V265438+. The format is as follows:

No Project Start Time Close Time Page Storage Quantity Frequency Print Radio

106: 30 07: 00 p6f397.1MHz is closed every day.

In the screen, the cursor turns left, F2 turns right, F3 goes up and F4 goes down through F 1, and eight tasks can be defined. You can select daily, Monday, Tuesday, Sunday, etc. in the project bar, so that V2 1 can listen to the radio or print satellite cloud pictures at a fixed time every day or Monday (or second class).

Sony CRF-V2 1 can connect with computer system to exchange data through RS-232C. In addition, V2 1 has very powerful query functions: automatic SACN tuning, limited scanning tuning, activity search and spectrum analyzer.

On the right side of the screen, there is a signal intensity display, which shows up and down, and * * * has 10 squares.

Frequency modulation reaches the sensitivity of car radio. I can receive 89.0 Zengcheng \90. 1 Shunde \94.6 Foshan \98.0 Macau \98.5 Foshan \10/0.7 Panyu \ 103.4 Huizhou, which are very difficult for ordinary radios to receive. The FM of V2 1 is variable frequency.

Medium wave performed well, and T2FD short wave antenna was used.

Whether the short-wave receiving performance is good or not actually depends on the supply of T2FD antenna. It is quiet when listening to short wave, which is obviously higher than GRUDDIG S800 (Desheng HAM2000), and the voice signal of SSB is also clearer than S800.

Although the speaker is not big, the sound quality is good, and it feels very resistant to listening for a long time. I'm used to listening to GRUNDIG's traditional Sony stereo. Of course, I feel that the sound of V2 1 is not pleasant to the ear, and its sound quality is already very good for the communication receiver. The radio part of this expensive receiver is quite good, and its satellite cloud image function, RTTY function and fax function are of little use to the current information society.

When designing this model in the early 1980s, more attention was paid to users with special needs, such as offshore fishing, oil drilling platforms and their supplies, translation services, sports exploration, geological exploration and animal research. Foreign countries have a strong awareness of personal safety, and organizations and institutions that have been working outdoors for a long time are very concerned about high-level meteorological and hydrological services. Therefore, the slogan "Open the door of information and entertainment for you" has summarized the design idea.

With the development and application of radio technology, computer technology, satellite technology and ground communication, these meteorological and hydrological services have been undertaken by professional information consulting companies, and users in need can get all-round information and rescue services through registration and payment.
