Repeater updates

146.060+ 123.0
443.900+ 94.8

Vince, N6OA, is generously providing WIRES-X support for the 70-cm machine. WIRES-X access is digital-only. The repeater will still pass analog traffic, so those of you with analog rigs, please check the S-meter before transmitting. Also, because the duty-cycle has become rather high, the output power of the 70-cm machine as been reduced to 25W. This will allow a 100% duty-cycle without power drops.

On the 2-meter side, the new amp is in place. A bit about the new amp is in order.

It is fairly common knowledge that YSF repeaters are unable to maintain 100% duty cycle at full power. They start out at 50 watts, but as they heat up, the power is reduced to 25W. We see this when folks from St. Augustine, for instance, join our net, check in, but as the net goes on they stop hearing us.

We now have a Henry Radio C130AB10R amplifier doing the heavy lifting. Our DR-1X now puts out 5 watts, well within it’s capability. The amplifier is a 10dB system which, while capable of 100W, is only asked to provide 50. The hope, is that through not running anything full-on, we can extend the life of the entire system and have a more consistent operating experience.
