TWR DRM Return to the Air

Hi everyone,

Most of you know that Typhoon Mawar damaged KTWR's antennas to the point that no broadcasts have gone out from that station for the past two weeks. Several factors have made it very difficult for the team on Guam to get the antennas back in operable condition. We are sorry that is has taken so long to resume broadcasting from this site.

In the meantime, TWR has been working diligently to find other broadcasters who can air our programs during KTWR's downtime. As of the time of writing this note, ~50% of the KTWR programs have been covered by other transmitter sites. This includes some of our DRM broadcasts.

As of Tuesday, 6 June, the following DRM broadcasts will resume. They will be transmitted from Tashkent.

Frequency (kHz)       Day      Time (UTC)     Coverage Area

15390                        Tu-F      1515-1545       South Asia

15390                        Su          1500-1545      South Asia

15205                        Su          1600-1630      South Asia

We will keep you posted on the progress in getting the rest of the DRM broadcasts back on the air.

73 and may the Lord bless you.

DRM Frequency change for mid-A23

 Hi everyone,

We have been greatly encouraged by your continued listening to KTWR's broadcasts and sending us reception reports that show you are listening to the programs. This helps us keep the programs on the air.

It turns out that reports have shown that propagation is not quite as solid as we had hoped for the South Indian language block on Sundays at 1600-1630UTC on 15205kHz. We believe that the 22-meter band will be more stable at that hour. Effective 2 July, this broadcast will change from 15205kHz to 13670kHz. Power will remain at 90kW.

Please let us know how the change affects reception. Thanks for your help.

DRM on 12055kHz is Coming Soon

Happy new year everyone.

The 12055kHz broadcast to South Asia will start the first week of January. This will be Tues-Fri at 1515-1545UTC. The God Centered Life program will be in English. It is expected to last at least until the middle of the year. 

KTWR will be beaming this at 90kW at 285 degrees. It will be interesting to see how coverage differs from the 15390kHz Sunday DRM broadcast that is at the same power and azimuth. Reception reports for both broadcasts would be helpful.

 We are planning special DRM broadcasts for Christmas Eve, 24 December 2022.  These will be during our regular Saturday evening DRM broadcast slots to China, 12040 kHz at 1100 UTC, and Japan, 9910 kHz at 1200 UTC.  We will be airing two audio services for each program, Mandarin and Cantonese at 1100 and Japanese and Korean at 1200.  These will be accompanied with slides.  64QAM modulation will be needed to support the higher data rate.  This will require an SNR at the receiver of about 17dB vice the 13dB threshold for 16QAM.  We hope you'll be available to listen and that you receive a strong signal!

The weekly Japanese language program, Every Man a Warrior, will still be aired at its usual time, 1130 UTC, in 16QAM format.

Delay in Broadcast

Hi Everyone,

One of our DRM blocks (12055kHz) that we thought would start at the beginning of the B22 broadcast season was delayed until the beginning of 2023. We also decreased the 9910kHz to China from M-F to only be on Mondays.

DRM broadcasts (Effective 30 October 2022):

 

                                                                           Designated

Day              Time (UTC)        Frequency        Coverage Area         Language

Saturday     1059-1129          12040 kHz          China                       English

 

Saturday     1130-1230          9910 kHz            Japan                      Japanese, English

                         

M                 1215-1245         9910 kHz            China                      Mandarin

Sunday        1500-1545        15205 kHz           India                        English

Sunday        1600-1630        15390 kHz           India                        South Indian languages

Another change we are considering is to move the 1600-1630UTC block on 15390kHz to 1030-1100UTC on 15200kHz. This is to take advantage of better propagation at the earlier time. If you are in South Asia, please let us know your preference. We can either leave it as is or move to the early time.

Thanks for tuning in.

KTWR B22 DRM Schedule

Hi Everyone,

Thank you so much for your patience while the team on Guam battled several component failures in both of our TSW-2250Ds. It was a tough slog, but both transmitters are up and running at full power. We are grateful for the other broadcasters who helped us with analog broadcast coverage while TX6 and TX7 were down. One thing we learned is that it is very difficult to find other broadcasters who could cover our DRM broadcasts. In fact, no one could do it. That reinforced the importance of KTWR's DRM broadcasts.

We will definitely be continuing DRM transmissions in the B22 broadcast season. In fact, we will be adding to our current schedule. Here is the B22 DRM schedule:
