Hi Markus I was just up and running to catch the (cats) tail end of Uwe's transmission I look forward to the next excursions. Re the improvement over the years in Uwe's signal. Here I have not seen signals recently as good as those in the past I am sure, I will look up my captures. Secondly I think I saw an improvement when the QRG moved to 8270Hz. Of course this is a very tenuous observation, just a gut feeling but often those are highly reliable indicators of fields for investigation. 73 Eddie --------------040509020308020706030505 Content-Type: text/html; charset=windows-1252 Content-Transfer-Encoding: 8bit On 19/01/2014 12:18, Markus Vester wrote:

The improvements of Uwe's signal at PA1SDB over the years is indeed impressive. Uwe, can you perhaps comment on your antenna size and current, then and now?

Hi Markus

I was just up and running to catch the (cats) tail end of Uwe's transmission I look forward to the next excursions.
