kchibo DSP-D92L

Kairon’s DSP technology can be said that with each passing day, a flash, DSP radio less than a year after another, from the second half of last year to now successfully launched two new FM / AM two band radio (D90L, D91L) and two wide-band radio (D39L and D48L). And actively listen to the views of fans, continue to improve. DSP technology is reaching maturity, resolve the DSP in a number of radio problems. End of this month or early next month a more mature DSP and the majority of wide-band radio enthusiasts also met.

D92L been located in the entry-level amateur radio DSP products, is because it is the time in R & D just want to make up for gaps in the numeric keypad machine, the machine did not expect the prototype came out beyond imagination, is very excellent. So Kairon who after careful consideration, has been re-positioning of D92L, which is our current positioning of the origin of this product. I use the term from two days, Kairon people are still very modest, we can be seen.

A, D92L introduction of stand out

★ 1, the first numeric keypad and jog while the DSP radio
Before, German students have used Shuttle DSP radio tuning, tuning up and down than with the Shuttle key to the more convenient, so D92L addition to the shuttle, was added to the numeric keypad to enter, for fast tuning play an important role.

★ 2, the first step to 0.05MHZ FM
Explain here, stepping to 0.05MHZ, tuning can be achieved only with the shuttle, keyboard input or tuning up and down keys or only the minimum step of 0.1MHZ. This is, for the FM frequency is shifted to 64MHZ, listen to TV sound can be very important, although the original D39L and D48L FM frequency range of 64-108, but because the minimum step to 0.1MHZ and high selectivity can not listen to the DSP TV sound, very sorry. It can be said in my repeated calls, and eventually I am very satisfied.

★ 3, AM bandwidth selection
Medium wave and short wave radio listening, press the “IF bandwidth” button, you can improve selectivity, reduce adjacent channel interference. D92L bandwidth has 1KHZ, 2KHZ, 3KHZ, 4KHZ and 6KHZ, bandwidth, but also take into account quality, noise.

★ 4, “FM de-emphasis” function selection
De-emphasis is based on the different regional broadcasting standard, increasing 50μS and 75μS function selection. In some European countries FM de-emphasis of 50μS, FM de-emphasis in China is 75μS.

★ 5, stored information will never be lost
Can be released from the first DSP radio, the calls have continued, and finally realized D92L. Engineer for the Kairon applause. But the time and date information, or to re-adjust

★ 6, high-capacity storage
Pace is still very large, the storage location once reached 900, although it is not dynamic storage, or each band 30, page 10. But we can according to different time periods, different regions would not have fun store radio stations.

★ 7, short-wave step
AM tuning step for the Shuttle 1KHZ, up and down keys to 9KHZ. Shuttle shortwave tuning step for the 1KHZ, up and down keys to 5KHZ.

Second, the same door with the machine before the DSP similarities

★ 1, the same battery and D48L for 550MAH, also sent two batteries. But the charger is not filling in the machine outside, and handy to provide external power supply is similar.

★ 2, software similar to KK-S500, the first step buttons are lit backlight, the second step is the actual operation.

★ 3, Shuttle similar KK-S500, stall a little sense.

★ 4, the sound quality may be the best DSP products, there are KK-S500 taste.
