Why Wide?

During Check-in Malaysian 40m Net - 7130 MHz

Nowadays, propagation changing very fast..at this time we need some more power to penetrate the QRM but with widen tx bandwidth audio also can penetrate..this happen because with widen audio, we occupied more bandwidth to penetrate the QRM also..with two this work together power & wide bandwidth it's will be easy to others station to copy us..Just watch the video above & you will taste it..hi hi

p/s : Thanks to 9m2avb for recording.

Even feel too tired with routine works, still have time to this hobby..After got some advise & link from Ferry (Yb0AR), manage to play again to increase with TX bandwidth on this radio. Special thanks to Peter (G7VKK) for this kind of idea..very good also explanation from him..by using sound card & software inject to I.F Filter (12khz) at TS2000 (pre-installed), now this 'toy' can give almost 7kc TX bandwidth. No need madness modifications..May be most peoples will say 'splatter' but for me we have to try then we know..with word 'Experiment purposes' why not we try..hi hi..can say now I'm very happy with 7kc TX bandwidth on my TS-2000..Next project will be change LED light for LCD screen with Blue color..hi hi..Full story are here..

Audio

Recorded by YB0AR

After done change Telefunken ECC83 Tube for MIC-200, now going further to touch-up little bit at EQ to get balance audio with current tube..you can hear some different with my audio now..separation, clarity is much better now..even we get much at low-end but we have to balance with hi-note to make sure people can understand what we talking about..our voice natural at mid side..so, we need to tone down mid-range at EQ to get audio more natural..so, enjoy the short video above & if possible please use your headphone..just do some sharing..
