First part done

The first ARRL weekend is over.
It started with heavy rain Friday afternoon but it cleared up Saturday afternoon and the remaining of the weekend was fairly OK besides some snow Sunday.
Managed in total of 39 QSO's with some new stations and some worked before.
Think the activity was higher this year compared to last year and Sunday evening activity was very good with a lot of stations QRV.

I believe the smallest station worked was K1DS with single yagi and 100W or so.
One funny thing was Tobbe SM7EOI who lives 35 km away uses 4 * 11 el DG7YBN antennas hrd good but we missed to work before my noise became to high at MS when I beam into my house.
We can only work when doppler is high as the tropo signal is so strong.

Did make a switch box for the pol switching Saturday afternoon but it did not work on the RX side and the moon was on its way up so I left it with fixed RX H.
Did work XE2AT with TX vertical and RX horizontal and tried to call CQ a few times V but got no reply's.
Later on Sunday afternoon I found that the cable I used from the relay switching the two RX cables in the shack was short circuit so after replacing that it worked as planned.
The preamp for the V antennas had lower gain so the noise level dropped but it worked well.
Worked JE1TNL using both TX and RX vertical so the system works.
Compared a lot with HB9Q RX on livecq when I changed the TX pol and all times it shifted 90 degrees and a bit lower level on V as expected.

Worked Bernie ZS4TX who has the exact same array as I do and when he TX V he was like -10 with me and when TX H he dropped to -27 so a huge difference.
Listen a lot on Bernd DL7APV with different pols and at some point he was more or less gone when I RX V.

Experienced some noise from time to time and did walk through the house with my 817 with a rubber duck on but did not find any source of extra noise but need to continue the investigation as I believe I have something interfering.
Some times I can detect noise with patterns in Map65 both in freq and time domain.

Sunday evening I had problem with MAP65 hanging when trying the decode so I could only at few times report to livecq.
Do not know why and I have never experienced anything similar before but Sunday night it was constantly hanging.
Besides from that and some high VSWR when antenna soaked the station worked without any problems.
Need to find some good settings for CW until the next leg as I tried a few times but CW does not sounds pleasant with my settings at the moment so I did not work any.
