I have been trouble shooting a problem that arose in the shack. The problem is that while in a qso my kat500 will start rising in SWR's. I decided to check the system out by hooking a dummy load to the coax connector at the tower. The K Line performs as expected. SWR are 1:1 and it sits there

[Elecraft] KX3 - Switching power source while operating

2017-06-28 Thread Terje Elde
Hi, I’m wondering if anything is known about how much of an intermittent loss of power a KX3 will more or less not notice, during full use (transmit at 15W), and during receive? Asking because I’m considering some power solutions, and wondering if it could be useful to switch between multiple

Re: [Elecraft] KX3 - Switching power source while operating

2017-06-28 Thread Don Wilhelm
Terje, A loss of power will not allow the KX3 to power down gracefully, so some information such as what frequency, mode, and other data may be lost. To insure a seamless transfer between batteries, you may want to design your controls so that two battery packs are in parallel for a short time

Seems to me the most straightforward approach would be to put a set of batteries in the KX3. Then you can drop and restart external power without worrying about the time delay. The radio won’t care. Only thing you might have to do is adjust output power if you were operating above the

As Dick mentioned this is the most likely reason. There is another power management setting that should be checked and disabled as well. Open the device manager, and expand Universal Serial Bus Controllers. In there there will entries such as Generic USB Hub, USB Root Hub and each of these
