Spring is here and it is antenna time. Peter PA4O (Ex PA4PS) helped me with mounting a second 16 el M2 yagi in the middle versa tower. We now have 3 equal 2 meter systems for 144MHz.
A fourth is available and will be set up for the contest weekend only. This is a system with 3 clover leave antennas. This system can hear 360 degrees. The cable from the clover leave system is connected to the eme system so we can use the relays switch of the antenna. After the contest we only have to reconnect one cable and the eme system is back in business.

I bought 80m of 1 1/4 inch (39mm) Celflex hardline coax. This will be used to feed the double ten switch in the field.

The computer for the 6 meter table had a problem. It switched of and I could hardly start it up.
I found out that when I connected to the internet the computer shuts down. I mounted a second ethernet card and now it is up and running again.

Next weekend the VHF UHF SHF contest season is starting.
Before we can start I have to do some repairing and preparation.

Today I went to Jaap PA0T. One of my 1144 MHz preamps with a smd hempt fet in is broke. These smd fets are too small for me and Jaap would like to help. We were lucky. It was not the fet that was caused the problem but a loose contact. We also looked to one of the driver pa’s. It would not switch. It was repaired before and a switch transistor made bad contact. This was a easy repair but hard to find.
