Yosan Excalibur radio station review

The main feature of this radio station is form factor 1DIN(the size of the car radio), thanks to which the popular question"Where to install the radio station in the car?" Yosan Excalibur (Yosan Excalibur) can be easily connected in almost any car that has a niche format 1 DIN, while you get the convenience of station management without violating the aesthetics. In addition, the radio is "omnivorous" in terms of supply voltage. The internal converter allows it to be connected both on cars with 12-volt equipment, and on cars or buses with a 24-volt system.

However, these are far from the only advantages of Yosan Excalibur. The station has a very broad functionality and good technical characteristics, as well as thoughtful management.

The appearance of the radio

The front panel is made of high quality black plastic. It contains a loudspeaker, an LCD display, a 6-pin connector for connecting a PTT, keys and potentiometers for station control, as well as a two-color LED indicator. It signals the work of the station for transmission - in red, and for reception - in green.

Station building collapsible, has metal covers that are securely fastened with screws on the side and back. The rear panel has a connector for connection external antenna and a connector for an additional loudspeaker, power wires are removed, here the manufacturer has placed a plate with the station's serial number.

Walkie talkie display has two backlight colors - green and orange, symbols are perfectly readable from any angle of inclination. Due to its large size, a rather large number of indicators can be displayed on it at the same time: channel number and frequency, modulation mode, power level and signals on the air, type of squelch, etc.

Yosan Excalibur Controls

Excalibur has dual potentiometers, with the exception of the CH channel selector. All of them have a smooth ride, there are no backlashes. The outer regulator is ribbed and the inner regulator is smooth.

Regulator PWR/ VOL - turning the station on and off, VOL-adjusting the speaker volume.

Regulator MIC/ SQ- microphone gain, SQ allows you to control the operation of the threshold squelch, while being a button for calling additional functions FC.

Key AM/ FM / MENU- switching the modulation mode amplitude or frequency / call the menu.

Key SCAN/M. SCAN- scan mode for all channels and scan for channels / stored in the memory of the station.

Key EMG/SHIFT- switching grids / switching frequency offset 0-5.

Key MEM/M. SAVE- memory channel selection key (channels are assigned to function buttons) / storage of channels.

Key ASQ/LO. CT- enable or disable automatic squelch / key lock.

The control keys are backlit, which greatly simplifies the work with the station in the dark. Additional functions called up by pressing the potentiometer FC.

TangentaYosanExcalibur has an average weight and dimensions, it is convenient and pleasant to use. The cord is soft, therefore, it will not "tan" in the cold and subsequently break.

The headset has a push-to-talk key, channel up / down buttons and a button that is responsible for turning on the automatic squelch. The UP, DN, ASQ buttons have a blue-white backlight, which makes it easier to control the radio at night.

You have more questions than answers, then the material below is for you. This is a review on one of the worthy representatives of the CBC family, Yosan Excalibur radio stations. Excalibur, one of the few stations capable of meeting the needs of a wide range of CBC users. This copy came to my desk by accident. My friend asked him to modify it. Of course, I took the opportunity to review it.

Unfortunately, I got the station without a box and I can't say anything about it.

Appearance
The radio station is made in the form of a monoblock. It has standard dimensions 1DIN, this is its feature.

9. Channel selection knob
10. Modulation selection button. The second function is to call up the station tuning menu (via the FC button)
11. Channel scan button. Normal scanning occurs within the same frequency grid. The second function is to scan memory channels (via FC). You can change the scanning direction by turning the channel selector knob or using the buttons on the headset.
12. Button for switching grids. The grids are switched sequentially. There are 15 of them in this station, 45 channels in each (holes are enabled by default). The second function is to switch stations to zeros and back to fives (via FC).
13. Memory channel selection button. To select a recorded channel, you need to press the MEM button, the letter M will appear on the display, then you need to press one of the buttons below the display. Although they are not signed, they are also memory cells. AM / FM - 1, SCAN - 2, EMG - 3, and so on. To write a channel into memory, the actions are the same, only you must first press the FC button. Indicator M will flash.
14. The button turns the automatic squelch on and off. The second function is to enable key lock mode. All buttons are locked except for the automatic squelch on / off button on the headset.

Menu

The station has a menu. It has 4 points. It is called up by successively pressing the FC button and the AM / FM button. The name of the menu item is written on the left, where the frequency is usually located. The mode is changed with the channel switch knob.

BEEP - turning on and off the sound of the keys (ON - on, OF - off. When turned on, the "note" symbol appears on the display, on the left, above)
ROGER - sound signal end of transmission (ON - enabled, OF - disabled. When enabled, a "double note" symbol appears on the display between the channel number and the frequency)
COLOR - display backlight color. (01 - green, 02 - orange)
LIGHT - display backlight brightness. (BR - full brightness, DI - reduced brightness)

Return to factory settings
If the station does not work correctly, or you want to clear the memory channels and return to the factory settings, turn on the radio station while holding down the AM / FM and MEM buttons .

Inside
The station was made at the Nextron plant in China (small letters below). Serial number the station starts at 1211.

Installation is made on a green PCB board.

On the first IF, 2 filters are soldered, this is a plus.

Editing is neat for the most part, but there are a couple of unpleasant moments!
The VCO unit seemed to have been soldered after assembly. What the Chinese were doing there is not clear, but everything works.

The station can operate from a voltage source of both 12 and 24 volts. For this, the station uses a voltage reduction circuit with a large resistor dissipating excess power. The station can work in trucks without a 24V -> 12V converter!

The board has a socket for connecting a CTCSS module. Unfortunately, Yosan does not put them in its stations anymore.

The output stage is built on transistors 2SC2078 and 2SC2314. Output power 8 watts. Both transistors are screwed to the back wall, which improves heat dissipation, thermal stability and protects against vibration when using the station in a car.

Heat exchange is carried out through a thermal pad, which is not very good. The harness is nearby, soldered to the mass sloppily (reminiscent of an explosion). Iron filings and flux residues were found on the board and case. When finalized, it was all cleaned out.

Outcome
If we close our eyes to the flaws in the installation and some shortcomings, then the station turned out to be good. She's really worth your attention. Featuring a wide range, dual noise suppressors and extensive functionality, the station is able to satisfy the needs of a wide range of users. Modification is strongly recommended, since the above flaws can cause unpredictable behavior and breakdown for the station. Otherwise, the station can be recommended for use both in a car and on a base for solving a wide range of tasks.
