Broadcasting Again After a Natural Disaster
By Jon Hill
After Super Typhoon Mawar slammed into Guam on May 24, listeners in far-flung countries who count on KTWR to bring them spiritually nourishing broadcasts found that their radios went silent.
Winds of at least 108 mph swept over the TWR shortwave station’s radio towers, damaging all five curtain antennas, two of them severely. Not knowing how long it would be before KTWR broadcasts would again reach those uncountable listeners across Asia, ministry staff hastened to contract with other outlets to temporarily carry some of the programmings. Other team members buckled down to repairs.
Amazingly, through the blessings of the Lord and the hard work of our skilled staff on Guam, a healthy portion of KTWR’s regular program schedule is already back on the air. One rough estimate indicated that a third or more of the station’s gospel broadcasts are going out again, including to countries of special concern such as North Korea and China.
TWR Vice President for Asia Daryl Renshaw said he is thankful both for the resumption of some of the broadcast ministry to North Korea and for TWR supporters who make the outreach possible.

KTWR updates their DRM schedule
From KTWR Guam:
We ran into some unexpected
interference with our 11860kHz DRM broadcast at 1358-1428UTC. As of this
Friday, 10 December, we will move it to 11890kHz. We hope this will greatly
improve the SNR in central India.
73 and have a great Christmas.

One final DRM Test from KTWR before winter schedules
![]() |
| KTWR QSL |
Hi Everyone,
While we are very close to the B21 broadcast season, we have one more DRM test to try this season. We want to verify that we can broadcast dual language services with our automated playout system. (Years ago, we proved that we could broadcast dual language services with a more manual approach.)
On 30 October, the English block to China at 1100-1130UTC will be replaced with Mandarin and Cantonese. The English part of our Japanese broadcast at 1200-1230UTC will be replaced with Japanese and Korean. This test will be only for one day. Speech audio will be computer-generated, so it may or may not sound slightly unnatural. Feel free to let us know how the audio quality turned out.
Running dual languages requires KTWR to use MSC=64QAM instead of our normal 16QAM. This will require a better SNR to decode than what is currently required. Current solar conditions appear to be

KTWR begins DRM in English on August 5
Hi Everyone,
KTWR is about to start regular DRM broadcasts to four different areas. We will do one day per week to each of four areas starting 05 August 2019. We will be working with the content server parameters to come up with the best compromise settings for each area. Each week will have different settings. We would really appreciate your feedback for as many weeks as possible. Your assistance will ultimately help give your fellow listeners the best possible reception in the long run. For now, all programs will be in English.
The schedule will be as follows, starting the week of 5 August through the end of the A19 broadcast season:
All times UTC - 05 August, 2019
Monday 11580kHz 1215-1245 target to South Asia 90kW
Tuesday 11995kHz 1026-1056 target to ANZ/South Pacific 50kW
Wednesday 11995kHz 1026-1056 target to China 50kW
Thursday 11995kHz 1026-1056 target to Japan/Korea 50kW
We hope you enjoy the broadcasts.
