Weather station again On Line

Since June 2022 my weather station is on line and uploading again.

After moving to out house in February 2015 I didn’t upload weather data until 01.06.2022.
Before moving to our house I was using an old Dell notebook, running Windows 7 and WSWin32 to download data from my TFA Nexus weather station and upload it toInternet.

Since June 2022 I am using a Raspberry Pi 3 to download the data. Onec downloaded the data is than processed und uploaded using WeeWX.

You can find the uploaded data here.

End Feed Half Wave antenna for SOTA

As SOTA is becomming more and more an issue for me and I would like to act not only as hunter, but also as activator, I decided to build myself a multiband EFHW antenna. My choice fell to the EFHW antenna as built by HB9EAJ.

Here are some pitures of building the antenna.

Testing is still open. The test will be done as soon as i find some time for.

YAESU FT8100 2m TX problem

Some fellow HAM’s told me that my transmission sometimes “gets lost”.

Some time ago I have found two possible reasons for this problem.
First possible problem was well known “thermal faliure”. After opening my radio I have found the suggested modification allready made, so I had to look further.
After some search foud an article describing the problem with VIA’s (VIA – latin for path or way, electrical connection between copper layers on printed circuti board), so I made the modification on my radio.

I hope the problem is solved, waiting for the feedback from my fellow HAM’s.
