Today I began to remove the damaged antennas and the old cabling. My little Angel, Marie, helped me all the time! 🙂

OE3GWU QRT

On 2016-06-16, the local Firefighters helped to tilt my antenna array. 4 of 6 antenna’s are beyond repair. Only useable is the R5 and the Helix. All others are damaged. I plan to be on air in 2 month again.

A few days ago, I bought a GMC-320. I know it is a cheap counter, but still very reliable for Beta, Gamma and X-Rays. Alpha „Rays“ cannot be measured, but thats no issue. Here in Austria, we have no Alpha Source. Anyways, my future plans are to upload the Data to APRS (OE3GWU-15). OE3GWU-13 will stay my Waether Station. I cant upload the whole Data onto my -13 suffix. Well, I could do, but it wouldnt be displayed very nice on aprs.fi.

Currently, there is no reliable Windows or Raspberry Pi Software available that runs stable. I am in Contact with the Weather-Display programmers so they are updating their Software. I won’t do a hardware review here. There are tons of them on Youtube.

 

I just updated my Weather Station Controller.

The old Raspberry PI B+ was phased out. A new Raspberry PI B3 is now used. Also Weather Display 11.3 was updated to 11.5. Thanks to Brian Hamilton for the long running support.

Also the Controller now hosts my DV4mini Hotspot for System Fusion and is prepared to host my Geiger Counter.

The now free RPI B+ is going to be used on the Sternstein Repeater as DV4mini Hotspot. Then we have a continous coverage from Vienna to Linz using System Fusion.

About 1 week ago, the RMS Packet Digitpeater on our Nebelstein Repeater Site went online. It works like a charm – with standard TNC equipment. However we currently do have issues if people with a SCS Tracker or P4dragon are going to connect. The TNC-X cant decode their Signal very will. Therefore we decided to swap the TNC-X against a SCS Tracker. It is industry standard. We will publish information how older TNC’s need to be configured in order to work properly with the Tracker.

Anyways we are finished with the „Proof of Concept“. OE3ZK – Gert is going to publish an artice in our local Newspaper – the QSP.

For more info, pls email me.

On May 27th, my Hometown was hit from a Supercell. Ice fell in the size of 2-3cm (0,7-1 in). The Weather Station is damage, though will remain online. Wind speed and direction measurements are going to be wrong though.


On Friday, November 6th 015, the new Yaesu DR-1X at the Nebelstein Repeater Site went online.

Repeater Details:

RX: 145.037,50 MHz
TX: 145.637,50 MHz
Modulation RX: AUTO
Modulation TX: FM fix
Power: 5 Watts
CTCSS: 88,5hz

Caution:

CTCSS will be enabled in 2 weeks.

Thanks to Alois, OE3IGW for his great work as Sysop!

Yesterday, Peter – OE5KPN and I installed the new Yaesu DR-1X Repeater on the Sternstein. It is currently in AUTO RX and FIX TX (FM) Mode and works perfect. Using 20W of Power, it doesnt reach as wide as the old FM Repeater which utilized 30W, though 1st tests showed that the repeater works great. Franz – OE3FRU and Karl – OE3ELG were called as test persons. Both approx 50km away in Lower Austria had no problem working over the repeater.

I want to thank Peter – OE5KPN for the great work he did. Also I want to thank Franz – OE3FRU and Karl – OE3ELG for the tests that were performed. Ther tests that were done with you were indispensable.
