Radio Republik Indonesia has revealed that it plans to purchase four DRM-capable medium-wave transmitters. The public radio broadcaster says it intends to use the first pair to reach populated areas of the Southeast Asian archipelago, and the second pair for emergency warning in west Sumatra and West Java.
Freddy Ndolu, member of the RRI supervisory board, made the announcement during the Digital Radio Mondiale general assembly, which took place in March. RRI joined the DRM consortium in 2015.[…]

“This week old region region 2736 (renumbered 2738) returns to Earth view, giving the solar flux a much needed boost. This means radio propagation returns to the high side of marginal for amateur, shortwave radio & emergency operators on Earth’s dayside. Luckily, this monster region is not a threat for big flares or radio blackouts so GPS users should continue to enjoy decent reception, especially on Earth’s dayside.
Aurora photographers at high latitudes also get another brief chance for aurora views this week due to another small pocket of fast solar wind expected around April 12-13. On top of that, we have had some very strange lights in the sky recently due to a NASA rocket mission to study aurora (called AZURE). Learn the details of these stories, what conditions to expect and what else our Sun has in store this week.”

In April 12, ARRL will conduct the Frequency Measuring Test (FMT), a tradition that dates back to 1931. In that era, prospective participants were promised “a pleasant and profitable experience” and advised that taking part in the FMT would be a form of insurance against out-of-band operation “and the unpleasant consequences that follow.” Official Observers and Official Relay Stations were required to participate in the FMT or offer a darn good excuse. W1MK — the predecessor to W1AW — was one of a dozen or so transmitting stations. The 80- and 40-meter frequencies were confirmed through an arrangement with the US Department of Commerce Radio Division.
Accurate frequency measurement — at least to the degree that radio amateurs rarely worry about operating outside of an amateur allocation — now is almost a given. But today’s FMT leaders are able to accurately measure beyond the number of decimal places (out to 5) a typical transceiver will display. FMT announcements may conjure visions of a vast array of sophisticated laboratory equipment. However, while some of the most successful stations did have laboratory-grade gear, others got quite close with far less hardware.
FMTs take place in April and November. The November 2018 FMT results are available on the ARRL website. The actual frequencies were 3,598,726.31 kHz on 80, and 7,064,327.23 on 40.
Tom Wilheit, WX4TW, one of those measuring the 80- and 40-meter frequencies of transmitting station K5CM on November 8 to within 1 Hz or less, reported using an Elecraft KX3 transceiver and Spectrum Lab audio spectrum analysis software. Others used a similar approach. James Keeth, AF9A, reported using an “openHPSDR Mercury receiver, a 10 MHz OCXO reference calibrated against CHU and WWV, and WSJT-X frequency mode for measurements.”
Jim Michener, K9JM, depended on his Elecraft K3 and tuning forks to get within 1 Hz of the mark on both bands. Grady Harper, AJ4YA, got extremely close by zero-beating the signal on his K3 and adjusting the measured frequency “to correct for errors in my tuner.”
“This is my first try with this type of adjustment,” Harper said. “The fractional part of the Hz is based on length of time between beats. I guessed at this part.”
If you’ve never entered an FMT before, Connie Marshall, K5CM, offers informationon his website on how to measure the frequency of a carrier. Articles in QST also have covered this topic.
The April 2019 FMT will get under way at 0200 – 0225 UTC on April 12. The 40-meter frequency will be in the vicinity of 7065 kHz, and the 80-meter frequency will be in the vicinity of 3599 kHz. Details are on page 94 of April QST.
