This afternoon James 9V1YC, Ben 9V1KB, and I tested the likely coverage area for a proposed new repeater location at the home of Harish 9V1HP. The test went **better** than expected. We expect to establish a repeater at this location in the near future. (more)

On September 14 the population-wide rollout of the token began. I collected mine two days later for use while running because they're much easier to carry and to waterproof than a phone is. Today I finally got around to opening it up. (more)

A lot of people are up in arms about ARRL coughing up a $1M ransom to regain access to its data. There are several common objections, but they overlook any/all of: the business model of extortion, ARRL's avoided information security costs to date, how ARRL views itself, and/or how information security matures in the real world.

From September 20 through 22 I attended (virtually) IARU Region 3's triennial conference. Only a few of the topics discussed were immediate concerns of Singapore amateurs, but as IMDA generally aligns its approach with that of administrations in neighbouring countries I'd suggest that it's very much in our interest that concerns of our neighbouring hams are successfully addressed.

As planned, our new duplexer has made it possible for us to resume work on antenna configuration. We're particularly concerned about improving gain and therefore coverage to the east and realised that a short yagi might improve coverage for a large part of Singapore. (more)

Daniel 9V1ZV, Harish 9V1HP, and I installed the new duplexer (a Sinclair Q2330E) on Wednesday, however its TX insertion loss and VSWR seemed a little on the high side, so during installation we dropped power to 5W to avoid transmitter overheating problems. Today I visited again and with Harish reverted the antenna configuration to the two separate antennas that we've been using since the move after performing a simple empirical test of alternative configurations.

Singapore's Minister for Foreign Affairs and Minister-in-Charge of the Smart Nation Initiative — Vivian Balakrishnan — invited several makers and open-source advocates to a session with GovTech on Friday, during which a teardown of the first version of the TraceTogether token was performed. The purpose of the session included allowing us an opportunity to examine and learn about the token, and to propose improvements. (more)

Several months ago I observed an interfering signal very close to the repeater's input frequency (145.075MHz vs. 145.025MHz), which might conceivably push the receiver's AGC down to the point that weaker on-frequency signals fail to successfully lock the PLL so the receiver would not successfully demodulate them.
