I think you need to pay Rm100 to keep the old decoder, actually old decoder can be a very good digital radio

voilà, digital radio, sound is crystal clear LOL

so dust off your old decoders and put them to good use, but don't tell astro about you new found discovery

but do it quietly, we don't want astro spies who are strolling these forum to report to report to their boss and decide to encrypt the radio signal

you could send email to lyngsat asking them to update the list

there is better unencrypted sat radio alternative on-board satellite JCsat-3A at 128.0°E, but requiring 1.5m c-band satellite dish, bad news is astro decoder can not tune to these radio stations

from my understanding, signal transmission power as well as signal frequency determine the required minimum size of receiving dish

just look at those TV antenna, VHF has longer wavelength when compare to UHF, so VHF antenna is cut to have bigger size than UHF antenna

KU-band transmit at higher frequency, has shorter wavelength, thus required smaller dish, although bigger dish is welcome to reject more noise from adjacent satellite transmission helping dish to focus better, however at KU-band frequency more precision is needed to manufacture the parabolic dish

C-band at lower frequency, longer wavelength, bigger dish is needed

just like measat 3, jcsat got both KU and C band transponders on-board its satellite

each transponder on-board the satellite is independent, you can't switch off one transponder to improve bandwidth of another transponder
