To the south, where city lights interfere, the clouds appeared bright and dynamic, changing within seconds from glowing intensely to fading away. The green and red colors were visible only in camera pictures, while to the bare eye almost no color effects could be seen.

  Not seen that much snow in long time Strong  cold north east wind. the day before the 3cm XVTR was removed to prevent damage.

New beacons are now active from Lopik at 385 meters above sea level. 432,415 MHz 5,760 900 GHz 10,368 900 GHz 24,048 900 GHz 47,088 900 GHz  info: Bakens vanuit IJsselstein | Hobbyscoop.nl I heard the 3cm beacon PI7NOS on Monday, 21 December, on the first attempt despite poor propagation. Unfortunately, 10368.900 PI7NOS wasn’t heard during very good propagation on the 2nd Christmas Day, so I suspect it might be broken at the moment. I picked up OY6BEC at 432.401 with a very strong signal over 1257 km from IP62OA to JO33HG. On the 2nd Christmas Day, there was excellent tropo on 3cm beacons: LB2SHF S9, SK6MHI strong, SM7DTE, DB0XY, and OZ7IGY 9+.

   The Nordic Activity Contest runs from 18:00 to 23:00 GMT on the second Thursday of each month. It’s supposed to be all modes, but only FT8 activity was observed. Propagation included meteor reflections and some sporadic E. An attempt was made with FT4, but there was no response. PSK reports of my signal   5ele 400W

  The picture is just for reference. My system has different speakers, and the remote is a larger console powered by 1.5V D cells. I’ll share my picture if I manage to find it again. I received this system from an inheritance. There were some problems with it: after switching on, the volume was set to maximum and the remote control responded slowly — panic in the room! The loudspeakers had to be refurbished with new rubber surrounds, as the originals had completely deteriorated. The cartridge of the special linear turntable with servo system no longer followed the groove, seemed damaged, and was very expensive. Presumably this happened during earlier transport; when moving the unit, remove the valuable cartridge and place it separately in a protective box, and use the transport lock. The heavy platter also remains loose, so that should be removed as well. Unfortunately, too late — the damage had already been done. When moving the pickup arm, the servo followed the movement, so the ...

  I drilled some holes in the bottom to let rainwater drain out that could get in through the bearing gaps. My G1000DXC bearing pointer suddenly started moving uncontrollably and then stopped, making further movement impossible. I was able to move it using an external DC 12-20V, but the needle was stuck. Before this, it had issues turning at high speed—first in one direction, then in both. The last time I took the mast down, I saw a lot of water pouring out of the bearing gap. Inside, I found the internal potentiometer damaged, with the positive lead completely corroded and loose.  The 500-ohm potentiometer has 5.6VDC across it constantly when the rotor is in standby, so electrolysis can occur if moisture is present.  Before opening the rotor, turn it to the middle position opposite the end stop; there’s a mark on the top body indicating the end stop position. This ensures the movable end stop lever will not block at the wrong place. The potentiometer has a 270-degree end...
