John was a member of the North East Radio Club and was a long serving Amateur Radio Operator.

Unfortunately he suffered with Parkinson’s and spent his final years in a nursing home at Ingle Farm. He was a keen amateur and had his radios setup at the nursing home you would hear him frequently coming up on the liked repeaters.

Thanks to Tony VK5FBIC he was able to attend one of our Saturday afternoon meetings late last year, he arrived in style in and access cab. I spoke to John and he was over the moon to catch up with old faces.

Unfortunately I have no further details about any memorial services

Hi All,
Over the last couple of weeks we have had reports of  intermod
interference on the tail of our 70 cm repeater, most likely from a
commercial trunking system, most probably the SAGRN about 3km away.
To alleviate the problem we have replaced the duplexer, added an
isolator to the transmitter output, and invoked tone access to the
receiver using the standard tone frequency of 91.5Hz.
The delay in taking action to fix the intermod problem was due to the
time to purchase the isolator. We regret the inconvenience so far and
would like to hear reports of the transmission quality after the fix.
We would also ask that you pass on any further issues to us.
Cheers
