Hi Volker

?

If you run the X6100 on battery you won’t see any of the heat related issues but you are limited to 5w output

?

The single USB connection for sound and CAT is great and the only cable you need, BUT make sure you use as short a cable as possible and put a few clip on ferrites on it

?

I use a X6100 with a magmount on the car and go sit in parks when I can a couple of times a year and get UK to US and EU with 5 watts, just choose the quitter bands and I tend to work FT4 as less congested and more chance of making QRP QSO’s

?

If you run it from shack power supply you will see the heat issues as stock, ?I run mine at 11v with some heatsinks on the rear and it still runs warm but not hot

?

Also keep an eye, an X6200 is close, several ham stores are starting to get information out about it, seems to fix a few of the issues of the X6100

?

enjoy
