Yes, John. The display that I get with the Sims's configuration is so pleasant that I want to use it. But that configuration is hidden behind the TCP/IP address. I did make my own configuration but the final aspect is poor. (AAMOF, I am lazzy; or I've more interesting things to do?).

Hi The normal approach to running any GPS module is to initially let it determine what it’s location is. This process is called self survey. Many modules will let you save that location in the module. If you give a module a location that is wildly inaccurate and lock in that location, the

I believe that your problem still remains somewhat unsolved, as you should be getting good coverage over most of the compass except for the northern "doughnut hole". Instead, you're apparently getting coverage only to the W through NW. BTW, when using a T'Bolt I have my AMU thresholds set at

IIRC Lady Heather comes with a TCP/IP example configuration that connects to a couple of remote Thunderbolts, one of which is in Seattle. Are you sure that's not what you're seeing? John On 7/8/21 10:00 AM, Admin wrote: Chris, Thanks for your comments. However, how do you explain

Thanks to all takers. Now, I recognize my mistake. I shouldn't invoke LH by the Sims's executable. It is not enough to change the TZ and location, as I did. It seems to me that the signal strenght algoritm continues referencing to Seattle. Thus, most of the birds flying outside (270 to 315
