Some TLC for REAST Antennas

VK7ZMS attaching new repeater Antenna

Over the last couple of months there has been a noticeable degradation of the VK7RAD 2m Analogue FM repeater, with increased noise and crackling on the audio, and people requiring more power to get in to the repeater.

Additionally the club had been loaning a Bushcomm SWC-100S Antenna from VK7FAZE for 3 years, but it’s power limitations for non-SSB transmissions meant it was also time for a more permanent antenna to be procured and the loan returned.

A TET Emtron ED-52c was purchased as a replacement multi-band HF antenna and a Diamond X50N and these were installed last weekend, where it was discovered that the Heliax feed line to the repeater antenna was damaged, and it too has been replaced.

All up, a good 3 hours was completing the necessary maintenance and has been well worth it, with many users of the repeater mentioning the improved quality of the signal and Dave VK7DM is also reporting that where he used to need 40 Watts to get into the repeater with a clean signal, he now needs only 1 Watt!.

Thanks to VK7s SD, ZMS, ZBX, ZCR, FPCL and BEN for their assistance on the day with the maintenance work!

New Digital Repeater To Increase Digital Coverage

Yaesu DR-1X Repeater
On Wednesday, REAST repeater officer Damien Styles VK7SD commissioned the new Yaesu DR-1X digital repeater much to the excitement of the gathering of people at the Wednesday evening experimenters group. While the repeater was purchased some time ago, it has only been in the last couple of weeks that frequencies have been allocated by the ACMA for it’s usage.

The Yaesu DR-1X is capable of both analogue and C4FM digital voice and automatically switching between the two modes. Soon an additional module will be acquired to provide DMR, DSTAR and p25 digital voice capabilities.

This repeater is on air right now, with an output frequency 438.675Mhz with a 7Mhz negative offset for the input on 431.675Mhz.

Our repeater officer would be most interested to hear signal reports from you. If you are able to access the repeater, please let Damian know by emailing [email protected]!
