W6CX and Northern California 440 Repeater Restrictions

The power output on our 70cm (440) repeater has been reduced by 50dB due to a request from the US Air Force. This change is necessary to mitigate the interference issue affecting the PAVE PAWS radar (PPR) system operating in the 70cm band. This has resulted in the following changes to our repeater system:

• 440 and 220 are now permanently linked.
• The Morning nets that were run on 220 linked to 440 are now run on 220 linked to 2m.
• EchoLink and IRLP are both now accessible only from 2m.
• The Thursday evening net will be conducted on 2m linked to 220 and 440.
• The ATV output has been moved from 427.25 MHz to 910.25 MHz (experimental).

This is an issue that affects all Northern California 440 repeaters. Read more here:
