Re: LF: last night opera signals on LF

[DK7FC <selberdenken@posteo.de>]

Hello Domenico,

Nice to see the activity on LF. There are several new RX stations, due to the upcoming SDR kits in the recent time. So the ratio RX/TX stations increases :-)
Currently i stay on MF but soon i plan to be back on LF with a somewhat stronger signal again. Then i can overcome the noise floor of Paul's new receiver on LF, at least in QRSS-60 i guess :-)
The coil body is already here. I just need to wind the coil. I have holidays now, so there is more time...
Then i will leave some more messages on your EbNaut decoder.

Hello LF,

noted some nice activities on LF in opera segment last night.

Good detections of Dave G3XDV here in JN80, as usual.

2017-08-18 00:04:09 G3XDV   1796km 137473.788Hz   3mHz -39.5dBOp  82% 20.8dB
2017-08-17 22:49:46 G3XDV   1796km 137473.791Hz   8mHz -35.8dBOp  99% 21.0dB
2017-08-17 21:14:40 G3XDV   1796km 137473.792Hz   3mHz -37.1dBOp 100% 20.1dB

Compliments Dave for your signal: your station is a 'lighthouse' on LF.

Noted that also Tom, SM2DJK is again active in opera with his coherent transmitter.
No opds detection here but, observing his central frequency in 2 hours,
i found a carrier that most probably is  Tom's signal (see attached plot).

My LF EbNaut auto-decoder is again online  http://qsl.net/iz7slz/ . It can be reprogrammed easly

on any other LF or MF frequencies and timeslots on request, in case some operator wants to try EbNaut.

Main Rx antenna is still under repairs but i hope to erect it for tonight.
