Image of the current antennas for 2m and 6m (new on top) and the preamplifiers


First of all, the new antenna for 50 MHz is up on 22 February. This 6 element antenna I purchased from G0KSC and he calls it OP-DES design. First impression is a very different receive "feeling" to the 4 element, I have used throughout the past year. Some directions shown more noise and some a lot less noise, depending on whereto the antenna is pointed. Tropospheric signals I always receive show a bit more signal, as far I can see. But when the tower was still down with the new antenna pointing into the air, it was amazing silent. But still the antenna ist not tuned to the best matching, this will be done in the next days.
As I had the tower down, I took the chance to look after the preamplifier for the 2m antenna. Again a GaAs Fet transistor had to be changed. It is the 4th I have put into this SSB SuperAmp. They seem to be quite sensitive. Now the amplifier is working again and the station is sensitive. The first station received was almost 800 km away. Good start anyway.

By 27 February 2021 the antenna is completed and tuned. Excellent match now with VSWR of 1,07:1 or better from 50.0 .. 50.45 MHz.

Activity 50 MHz
27 February 2021 Completed the antenna
25/26 February 2021 Tried to receive signals from the moon. I think now, noise levels are too high.
23 February 2021 Made some digital contacts - antenna working well.
22 February 2021 New 6 element for 6m is up in 12m.
6 .. 19 February 2021 Extensivly tested the new WSJT mode Q65 with a good number of contacts up to 1200km.

Activity 144 MHz
27 February 2021 First time after long time heard signals off the moon on 2m (RX1AS)

Activity 144 MHz
30 November 2020 Late night 2m was open to South-West France. Only receiving.
21 November 2020 Worked some PA at about 450km, when suddenly EA1MX was in here for 15 Minutes over 1500km.
10 November 2020 Band open to OH, SM0, LY. Worked a whole bunch of stations over 1000km.
7/8 November 2020 Despite a broken preamplifier I could work about 22 stations in CW in the Marconi Memorial Contest (MMC2020). 730 km was longest distance into Southern Germany.
3 November 2020 10 QSOs in Nordic Activity Contest (NAC) in SSB/CW to OZ,SM4, SM0 until PreAmplifier went dead.

Activity 1296 MHz DL0SHF Remote
28/29 November 2020 ARRL EME Contest Part II. Made 34 more contacts for a total of exactly 100 - all in CW mode. Some dupe contacts, so resulting in 89 stations worked on 23cm. Had some computer problems in between.
27 November 2020 Worked some stations in JT65C mode
7/8 November 2020 Worked 7 stations in JT65C mode. Most of them were very small stations with one or two yagi antennas and power around 150 watts. Charlie G3WDG joined the group of operators at DL0SHF. Welcome
