It does a very good job of pulling the signal out of the noise. It works in NH, traditionally a fringe region, in all but the most shielded of rooms. I also had occasion to test it for Everset in Kangerlussuaq, Greenland. I found it had no trouble acquiring at any time of the day. If the ES100 does not do well enough for you, there is supposedly an ES200 available that uses a longer sequence for even more sensitivity.
The one thing I wish is that there were access to the synchronized analog signal and/or a 1PPS. Even a top of the minute would be useful. It only has the I2C digital interface. 73, David N1HAC On 12/4/18 11:35 AM, Tim Shoppa wrote: > Thanks for the heads up Tom!
