PI7NOS beacons

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.

   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

Beomaster 5500 Power Supply Failure and Recovery

  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 ...
