I can see it in Swansea IO81CR Using SDR-IQ, SDR-Radio software, 100m loop ant roughly E-W. clearly visible, with hints of what appears to be a 7-second flutter together with some much slower fading.
Hello group. Has anyone any experience with this SDR ? It looks interesting and I'm a bit tempted, especially as it works full spec down to 500 Hz and "usable" to 100 Hz. But as I have never used an
Nice strong signal on 137.772, which has slowly drifted down onto its present frequency and now seems to have settled. Is it five dashes or five dots? Martin GW3UCJ Swansea IO81CR.
I shall be testing using QRSS120 this evening. The transmission will be an 'X' starting at each hour from 1700 with the last one at 2100 UTC. Frequency will be 137.7755kHz. A 6WPM CW ID will be at th
Hello LFers, Do any of you live near Cardiff, Wales? My wife is wondering how they are doing in her home town weather-wise. 73, J.B., VE3EAR I live 50 miles West of Cardiff, JB. It's cold (for us, an
PA0A is running *considerably* higher ERP than me Martin, so if you are only getting a weak trace from him then you'll have no chance with my signal. 73s Roger G3XBM Ah, but just because it's impossi
On all wideband VLF grabbers, activity was visible on unusual frequencies this afternoon (Jan 24th): 18.6 kHz, 15:55 to 16:08 UT: long dashes 15.7 kHz, 16:15 to 16:30 two dashes 13.0 kHz, 16:37 to 16

Not me I think Martin as I was TXing in 2224,2228,2232,2236,2244 and 2248 slots. I really need to get the ERP up don't I! 73s Roger G3XBM No, I guess that it's PA0A, Roger. After shifting down, you'r
Still trying to get a report on 137.5kHz WSPR tonight with the QRPp output. Any reports would be appreciated, although none of the usual semi-locals are listening, so I may be out of luck. Roger G3XB
You only need approximate time sync - a second or two is good enough. 'JNT Oh what fun! Got the clock on the synched puter up, trying to get the clock on the duff puter matched up. Harder than it sou
Dave, Yes I can confirm a WSPR transmission from here in that slot too. Keep at it... 73s Roger G3XBM I can definitely see a faint WSPR signal on 137.550. Last transmission started about 22:34. Marti

Anyone else seeing a signal at 137.05 kHz? Not seen any mention on the reflector. 73 Terry GW0EZY Is it still there at 13:32 Terry? I can convince myself that I'm seeing a very faint carrier on SpecL
I'm getting a strong carrier with 5dB flutter on 13.070kHz or thereabouts at 18:30UTC. Anyone else see this, or is it local to me? Martin GW3UCJ Swansea, South Wales. SDR-IQ/ SDR-Console.
