Sanyi, HA3PG
GästThanks to the SAQ Team, it was an interesting experiment listening to the 100 years old machine, generating RF (or should I call it AF?) signal. Details in a few words below.
– QTH: Pecs, Hungary, Maidenhead grid JN96DB
– RX: MSi.SDR (later RSP1A in the afternoon) + converter to 10MHz built with an SA612 and modest front LPF to cut LF, MF and above
– ANT: Miniwhip (the classical circuit with J310 + 2N5109) at about 8m height on a pine tree, 10-12m away from the house, proper CMC filtering and grounding on about 40m length of 75 Ohm coax
– Signal: 599+ both morning and afternoon transmissions, I did not check exact level but definitely very strong and solid signal in spite of some digital QRM on the frequency
I also tried without the converter and any front filtering in the afternoon. The RX was suffering from strong IMD but still solid copy at about 579/589.
A short 1 min capture can be checked here:
Once again, thanks to all members of the SAQ staff, 73 and stay healthy, old boys.
Sanyi, HA3PG

GästI heard you clearly at 2 o’clock today, but the signal was faint, only RST 449. This was probably because of my new, but a bit unfinished frame antenna. My vintage Atalanta tube receiver also need some adjustments. Best regards, Arnold Goksøyr / LA6RPA Norway

Thanks 73 -
Markus Lemke
GästHey that was working quite good for this old receiver concept. Heard you not too loud, would give you 459 RST. Had quite some noise here despite I was in the garden, away from the house. The FSK transmitter at 18 kHz is much stronger here, which makes reception more difficult.
I highly appreciate the V-V-V SAQ loop at the beginning, this gives me a chance to tune my receiver. Tuning an old tube receiver costs some time – you know that.
looking forward to receive the 2nd message as well and hope that the signal will maybe a bit stronger here then.BR,
Mark

GästAlways a joy to hear the old lady starting up! First signals heard at 0843 UTC (long dash), then VVV de SAQ from 0845 until 0859 and then the msg with the kind recognition of all health workers everywhere…
Your signals were about 15 dB above the background in 500 Hz BW throughout in JP81nx. Some of the background was your own backwave, which was quite weak today but plainly audible. There was another strong VLF station on the frequency initially, but thankfully it stopped a few minutes before you started tuning up.
Equipment: 1 m long vertical E-field probe antenna => homemade upconverter 17.2 / 3467.2 => Drake R-4C
73, thanks and keep safe!

GästMaybe the staff can explain a little about the technical details (cooling, motor start and speed control, …) in English while starting up the alternator.
I’m looking forward to a good reception. -
