70cm Voice Repeater VK6RNS

HERE ARE SOME PICTURES OF THE REPEATER IN IT'S   CONSTRUCTION STATE!

This repeater will be on air in 2004 and hopefully will be linked directly to VK6RNC when it is placed in a permanent location. There is no CTCSS required for this repeater and it's frequencies can be accessed by all classes of Amateur licence. John VK6KK/VK6HZ currently is the repeater custodian for this 70cm repeater.

The front of the repeater and cavities. No the HP8549 analyser isn't a fixture :(  I think a suitable holder is needed to mount the handset microphone on the front of the cavity box.

The back panel of the repeater - new cables have been made - the circulator provides another 30dB isolation. Note the two parts to the cavity set - one is Rx other is Tx.

A picture of the 'retrofitted' FM92 PA (25W) and the controller - (a few small changes have been made since this photo was taken) - The Rx is on the right side of this picture. The original PA had blown up - but FM92 PA's are easier to find.

A close up inside the modified cavity set (top Tx side) - Notch - Bandpass - Notch is the configuration.

Here is a plot of the filter Tx and Rx - measurements plots will be added soon.
