QRV again after a long time beeing absent.
This was the first time i was QRV on 13cm. Although i had just 1W on this band i made some very nice contacts.
There were still good conditions because of a very nice tropo.
Despite foggy wheather in the morning it turned out to be a very nice DUR test this time.
Unfortunately the activity from Stations from within a 100km radius is getting less and less. Without ON4KST chat its rather difficult.
The picture shows my 1.5m dish with the 13cm box below. Many thanks for all the QSO ! Hear you next time, hopefully !

Currently a new draft european standard prEN 50561-1 is widely discussed. Amongst defined notches for amateur radio bands and dynamic notching for shortwave radio stations it also includes raising the allowed levels of PLT signals on mains lines by about 30dB ! This would mean that any SW radio close to such modems will be impossible.
There is a big discussion in forum.darc.de and in hamradioboard. There is the assumption that raising the levels for PLT will cause other electronic manufacturers to claim for higher interference levels as well. In addition future PLT modems will sure also work up to several hundret MHz to get the high bandwiths required for video streaming. This will affect VHF radios, broadcast radio and even TV broadcasting.
Therefore there is a openpetition which allows you to demonstrate your opinion against PLT devices and against this draft european standard:
Some very interesting background can be found on the pages of the IRT:
The german body for elaboration of electronic standards DKE will meet today (Oct. 22th) to decide if they will vote for or against this draft standard on european level. Whatever this decision will be it makes sense to vote against PLT in the petition above…
