Unfortunately they do not ship,this auction it is collection only. Otherwise I would have bid on the rabbit cages! 73 Clemens DL4RAJ co/catalogue-id-ramco-10106
Hi Mark and Chris, on http://www.waniewski.de/LW/Lakihegy/lakihegy_lw_1en.htm you can download a pdf file with a schematic etc. of a 135.6kHz & 540kHz 100kW/150kW diplexer Maybe that's a starting poi
Hello Andy, -125MDS means that noise is at -125dBm,not at -128dBm. You feed a signal of a sig gen into the receiver and adjust its level until a RMS AF voltmeter at the receiver's AF output shows an
Hi Stefan, The inside of your shack reminds me strongly on my first car,a VW Golf from around 1983..:-) Yours must be at least from the same decade. 73 Clemens DL4RAJ
Hi Genosse Stefan, I've just resonated my antenna aa inverted L on 137.5kHz (with 502µH) and wil be ready to receive in WSPR-2 as soon as you start. 73 Clemens DL4RAJ
Hi Stefan, here is a copy of the spots shown in the database between between 19:00 UTC and 23:00 UTC. 73 Clemens DL4RAJ == 2018-09-08 23:00 DK7FC 0.137425 -19 0 JN39 1 DL0AO JN59vk 349 89 2018-09-08
Hi Stefan, Capture area of a *lossless* small loop is defined by the formula 3*lambda^2/8pi and therefore independent of its physical size. The loss of real world loops increases with decreasing radi
Hi Markus, I've just checked 1476kHz. The carrier is S5,5 and the 1kHz beeps are clearly audible (R4). Slightly above 1476kHz a second carrier is visible which is probably IRIB. Distance: 186.45 km A
The carrier is right now audible and visible on a battery powered portable SDR (Reuter Pocket) with just a small active ferrite antenna. 73 Clemens DL4RAJ
Hi all, here a forward of Finnish station. 73 Clemens DL4RAJ Hello Clemens, are you in touch with the organisers? Please forward my observation to them. Funny to see the sides fade differently. Not a
Hi Andy, I would connect a sig gen to the RX port and probe the port with a storage scope. Feed the low power TX port into a 50 Ohm termination and probe it with the second channel of the storage sco
Hi Nicolas, I'm copying you audibly at around 476.205kHz with S3-4. IQ2MI 25Hz down is about 20dB stronger. There are also some other beacons active: DF5QZ in JO51HG around 472.75kHz with quite an un
Hi Markus, The longest palindrome I know is this one (today politically no longer correct though...) "Ein Neger mit Gazelle zagt im Regen nie" . :-) 73 Clemens DL4RAJ =link&utm_campaign=sig-email&utm
Hi Albert, congrats to your extremely rare spots on MW by two different Japanese stations. Great job. IIRC so far only DB0ABR has made it from Europe to Japan on MW in WSPR exactly once a few years a
