Looks great Dan, about what time did the switchover happen? which chart can we check it on, the possible change that is? When I remounted mine out further from the house on a pole, you could see the raise on the norm level for my area. :)


Oh, I see it now, wow, if that's it, you went from average of 55cpm's to 20cpm's on your map chart and your still in experimental mode.

The detector tube has changed from an SBM-19 to an SBM-20 so the sensitivity has gone down. My station has been in experiment mode for ages, i just had a look at my long term trends in RadLog and there looks to be some detections, take a look at the max detected values. They can be seen in shared data.
Not sure if they're real or bad connection to tube. The detector was on the wall in a work area where I am busy.

Dan, question, I just noticed that this is running audio, not a problem, but wondering, that output from that audio plug, is that just the clicking like I have now with my GMC unit that I have that use the TL-081 adapter? So I can feed this audio plug on this unit into my adapter like normal or is it strictly into the line/mic jack on the PC? I use all TL-081 adapters for all my units except for the GMC-280 that's USB. Most of my audio jacks are in use already, so I am hoping that I can just use the audio into the adapters I have in use now.

Yes you should be able to use the TL-081 adaptors, connect the audio line to the 3.5mm jack. I have a similar adaptor but mine didn't appear to work as expected, so this is untested.

radbox-20 update - decided to order longer lead time parts well in advance

- SBM-20 tubes ordered
