Hello Group, I'm observing a RTTY signal at evening since Monday. Mid frequency is 137 kHz and shift approx. 80 Hz. Impossible to decode it with my equipment. Monday it was *very* strong here, Tuesda
Hello Bob, I have been noticing this signal also, need to check during the day. have only been listening at nite and it is quite strong. Bob K3DJC FM19 York, Pennsylvania Oopss!? At State Side ? (Joh
Greetings LowFers, Observed the mysterious RTTY signal until 0140z last night. The signal showed strong QSB from "undetectable" on FFT screen to "colour red" in a time window of approx. 10-15 min. Ma
The carrier/rtty on 137,000 kHz - as mentioned in previous emails - could not be detected here (Thursday)+ But, instead, I can see a single, steady carrier on 136,997 kHz - even during daytime+ Is t
Hello Group, I hit the "SEND" key by mistake before the mail was ready :) Sorry...! Here the full contribution follows: The carrier/rtty on 137,000 kHz - as mentioned in previous emails - could not b
Hello Gang, I checked the band last night carefully : - The carrier mentioned by Peter / Marco on 136998Hz is not audible here but it is visible on spectogram with some QSB, readability between 'T' a
Hello Gang, Hi Holger, Saw your signal yesterday evening on FFT screen but had some trouble with my antenna matching. I can not confirm, that LX1PD was QRV today, but I can confirm that we had some u
Hello Gang, Hi Peter, When listening to the signals on LF earlier this afternoon I was surprised how loud they were (about +10 db above normal) Nothing unusual to observe from here. All signals seems
Hello Gang, Hi Marco, I discovered that plywood is not a good insulator, expecially after a rainy weekend and with 21 kV on it .... :((( Go to the next restaurant! Drink and eat somewhat, not too exp
Hello Gang, Hi Rik, I did not observe unusual conditions *here* on LF Tuesday the last few days. Since the Ionosphere seems to be quite "normal" over these days I have no explanation. Only the Tropos
Hello Gang, Hi Toni, Today I've made some comparisons of different Audio-filter settings and CW against Slow CW. All test were made blind and under real band-noise conditions with the main receiving
Hello Gang, For those who are interested in that topic, the MD thesis (Doctoral Dissertation) I have mentioned is: 54°16'N / 10°04'E, JO54ag 73 es gl de Peter, DF3LP
Hello Gang, [...] I agree. The 3 sec time is optimal with white noise QRN or short 'cracks', but many time I would have preferred to have 6 or 10 seconds when receiving with Lux or heavy statics. Agr
Hello Gang, My understanding of the GRAM software is that the 'dwell' time is just a period of wasted time idling between performing an FFT on each set of data rather than increasing the FFT length.
Hello Gang, 1640z: Heard DJ2LF/p with rst429 (with chirp) at 136.85 kHz. Called him sometimes but got no reply... 54°16'N / 10°04'E, JO54ag 73 es gl de Peter, DF3LP
Hello Gang, I heard DF2PY in the morning and in the evening calling CQ for longer periods. The signal was 579 to 599. I called for several times but no response. The signal of DF2PY always is well an
Hello Gang, Hello 'Geri', [...] Using the 25 kW ERP as a basis, Peter's signal is in the vicinity of 25 mW ERP. I don't know Peters real ERP but I thought it was more. I assumed already 35 mW for my
Hello LowFers, Added a gallery of pictures to my homepages: http://www.qsl.net/df3lp (Antenna, shack, etc.) Hope it works and will be of interest... 54°16'N / 10°04'E, JO54ag 73 es gl de Peter, DF3LP
Hello Gang, Thanks for interest and discussion! Rik, ON7YD wrote re DF3LP's elevated feed antenna: Until the lower part reaches the ground it will still radiate. It does not matter (except for engine
