Bolong radio HS902

THis article mirrors here from my old page of geocities that will very soon be deletd dur to Yahoo's proposals :(((

all radios together

Bolong radio is the oly analog radio of the picture with enhanced view ( ie at the left)


This radio has been the results of a replacement project with a Chinese friend who lived for a short time in the student residence two years ago. He used mainly that radio in offer to listen a bit to the local radio stations but also his homeland.

I give to him a Kchibo model found from the local market mainly the 515 which is a semi digital , ie having a digital readout but is fully frequency agile. More information n this radio you will find on the chibo.pdf file along with some interesting technical info also for Bolong.


Why I am writing this report , though I have already written in the pdf? This is because with the return of the PL200 back to the factory for servicing or replacement - a total of 4 weeks – and the C330 already given to my father in the country house , using big radios as 1102 and 1103 in the road is quite uncomfortable, requiring the use of cassette sized radios only in the chest pocket of the blouse which is mostly preferable for me. All that time I had the opportunity to use and test it more than previously. I also like to listen to the music when I am walking inside the city. And it impressed me very much with its audio fidelity.


Appearance

The radio is a bit thick-y with black color and metallic mesh surface over the speaker . I never use it as I prefer to use my earphones . It is a also relatively heavy compared to the C300

There are three buttons on the front face: ON button for FM one for AM , one stereo switch and onle lock switch all locatd on the bottom right position below the display . ON the top there is a 8 band sliding switch . ON the left there is a volume control a ON off switch and a earphone connector.


There is a stereo FM light and a band light( FM or AM ) and a tuning light on the top right position.

The thumbwheel is relatively small for my fingers at 1 cm of diameter and a little hard to turn . I prer it this way so that it doe not tune out for any reason .

As in result in most bands Bolong seems to have a better sensitivity or total audio result than 1102 except the 50 mb . ON 50 mb there were superhet images from the lower part of the 41 mb that mixed with the upper part of the 60mb stations ( 6200 and up)


You read my review. This is a result of more than 10 hours of testing usage.
