A quick update everyone – I replaced the 8Mhz crystal yesterday, it was a fairly straightforward task, although I did have to use a combination of a solder sucker & de-soldering wick to get the faulty crystal out as it was in fairly tight – Installation of a new crystal took less than a minute afterwards.

The good news is that #12000029 is back online – Radu has checked the data it is reporting and all appears to be ok with the dose rate and temperature.

I’ll keep it in my lab in the garage for a couple of weeks under testing then install it outside (when the Scottish weather permits!)

Hi there,

I’m the host of #12000029 and was also concerned about the readings! I was planning on e-mailing Radu, however he was already on it and diagnosed the fault as the 8Mhz crystal – I’ve now ordered up a replacement and will hopefully have a correctly functioning uRADMonitor within a few days.

Hoping the background radiation isn’t as high as previously reported and also that the temp stabilises once the repair is complete.
