2019-01-14 I participated in the UBA PSK63 prefix radio contest
PSK63 contest in fldigi Like in 2015, 2016, 2017 and 2018 I participated in the UBA PSK63 Prefix Contest in the past weekend. Before I really dove into the contest I first mounted a new end-fed 10/20/40 antenna which can handle more power and tested it.

It took a few tries to get the antenna tuned on the 40 meter band. I tested this with the amplifier which has proven to be really precise about the SWR of the antenna in the 40 meter band, as noted in my post about the ARRL RTTY roundup 2019. I had planned to get this antenna up and running before that contest but that did not work out.

After testing I switched back to 50 watts power without the amplifier because the rules of the UBA PSK63 prefix contest limit the power.

I made a total of 69 contacts as single operator 40 meter. I had a short look at PSK63 activity in the 20 meter band during daylight but it was completely none.

After the contest I tried some FT8 contacts on the 40 meter band with the amplifier active. The amplifier did not like this and went into SWR protection. I must have tuned it perfectly for 7.040 - 7.050 MHz but the SWR is already outside the limits for the amplifier at 7.074 MHz.

Update 2019-01-30: The 'recalculated claimed score' is 3933 points. I scored better in most previous versions of this contest!

Update 2019-02-27: Results are in: 66 valid contacts, 56 prefixes, 3696 points. Ranking number 19 Single operator 40 meter band, number 18 Europe, number 1 the Netherlands. Ok, only 1 participant from the Netherlands in that category, so that wasn't very hard.
