2019-07-08 I participated in the DL-DX RTTY Contest 2019 1 week ago
This weekend was the DL-DX RTTY Contest 2019. In the category 'B': single operator, multiband, 6 hours. Not in the category for dipole or groundplane antenna since I used the endfed antenna. I made 80 contacts, 37 on the 20 meter band and 43 on the 40 meter band. Propagation wasn't great and most of my contacts were search & pounce mode, answering calls from other contest stations. I did call CQ a few times, and one of those was spotted by the reverse beacon network instantly and gave me 3 contacts in short succession. Operation in the contest was limited due to other things in the weekend so I fitted in the 6 hour category nicely. I did some other things on the radio on Sunday and somewhere in the afternoon I noticed a funny electronics smell and the output power from the amplifier had dropped. I found out the output voltage from the modified HP DPS-700 GB server power supply had dropped to about 10.6 volts. Time to find out whether this problem fixes itself or it's time to find another server power supply that will deliver over 40 ampere current at somewhere around 13 volt.
