Peter, It's a known problem also here. There are several ways to prevent that noise slip into the DC feederlines. Assume that every situation will be different for each of us, depending the source of
Nice question. My friend Google couldn't produce an instant answer. What I know is that they used to have two frequency bands in use: 300m & 600m. Knowing that the MGY was a modern vessel assume he h

Geri is vy weak sandwiched between two beacons PIA (Italy) and PE. After exchanging callsigns he disappeared into the noise not a valid QSO. Good vis in SL see attchement. Understand that he just clo
Stefan, I can hear you, marginal... In QSO some other DL station (?) But maybe it's better to listen on 501kHz, possible the filter is less attenuated there. Have my doubts, because you are very deep
Tks Tom, It's an indication what we could expect from our "Behörde". - 800Hz bandwidth no restriction in mode. :-) I like this one: "die maximale Leistung nur dann auszuschöpfen, wenn es zur Aufrecht
Stefan, Yep, been R/O for 15yrs. About the PY/EU QSO to make things worse :-) In the 80's PCH (Scheveningenradio) had limited MF TOR-channels, as an experiment they opened a duplex 425/512kHz TOR cha
Stefan, Can you indicate were you listen in your CQ call? At te mom you are becoming better. Jan/pa3abk Now my RX and active antenna is much better after adding a band filter in front of the first ga
Mal, Consider this as how things are within the EU. Stefan is initially listening on 477,5 he has his computer (WebSDR) on 502, you were calling 501,7 (I guess) How many more variables you want to ge
Received an email from Wouter PA3WEG. The WebSDR is x-tal driven, but he will look at it to get the unit somewhat lower. He intends to widen the bandpass filter in such it will catch the lower end mo
Stefan, I have experience as a "former" user of 500kHz. Under certain conditions there are "ducts" which enables you with low power to cover large distances. One of my favourites was EU to Brazil. Mo

Stefan, Just be sure that the TX antenna is not coupled to the E-probe. ( De-tune the system when you check it) I'm mostly listening on my TX antenna, the E-probe is only a few meters away. These two
Could reach him once, just taking the chance of positive propagation wave. Albert managed to pre-heat the duct towards Moscow having -15dB. Mostly I differ 6-10dB with his signal. The last sequence P
NL may up to 505kHz :-) But with 20dB less reception it becomes difficult. :-( His sigs are increasing at the moment, but still on the noise floor. Have a good trace on SpecLab. Opera certified :-) J
Stefan, At the mom I'll will call you on 502kHz everytime you stop your CQ. And stop when your CQ starts again. There's some QSB on it but have peaks in the region of 4-5. Jan/pa3abk Can you indicate
Rcvd with a Yaesu FRG-7700 with "Chinese DDS" VFO & low profile antenna. Maingear is "fixed" on the "old" QRG WSPR/OPERA. So the reception could be better. Anyway results looks good. RX2: 21:21 @ -1,
