Dear LF, I copied this at 1440z today, on 137.700. "O" copy. I'm not sure if it actually was DL1EIE or somebody else calling him! It was a good strong signal anyway. 73, Dave G3WCB IO91RM nr Windsor
Hi, Lee, LF I have found that the core material used for the output transformer and feedpoint choke isn't too critical in push-pull FET transmitters like the G0MRF and other designs. I've used a vari
Hi, Ed. Thanks for the report. I called Nicolas F4DTL at the same time as Jeff called him! Nicolas and Jeff were both "O" copy. I also called G3MFW in QRSS mode on Saturday at 10:14z, but he didn't h
Warren, LF, I caught the "J" this time at about 0400z. Screenshot attached. (My ARGO calibration is slightly off- it reads 500 millihertz high!) My antenna is a 20m long "Tee" at 5m height, and my RX
Yes! Sycom is the name of the outfit. Well done, Mike. He also sells IRF540 100V 28A mosfets. Perfect for that 137 or 500 kHz PA... 73 Dave G3WCB --Original Message-- From: owner-rsgb_lf_group@blacks
Paul-Henrik, LF, You are correct. 3C85 is a ferrite, and has been widely used in transformer cores at LF, as reported by G0MRF and others. I have no experience of the material personally, as I have n
LF, Warren, Good copy of XGJ on the morning of 23rd Nov. Several call-sign strings copied. Best copy so far this season! 73, Dave G3WCB IO91RM nr Windsor, S.E England Attachment: XGJ_0400z_23_Nov_200
Dear Nicolas, LF, Lots of transmissions copied from F4DTL copied today, with much QRN also.Screenshot attached. Also copied DF6NM "M" and F6BWO "O". Lots of static crashes... 73, dave G3WCB IO91RM nr
Dear LF, I copied this fragment at 0400z this morning on 137,7805 There's definitely a "G" in there. Anyone claim ownership? 73, Dave G3WCB IO91RM nr Windsor S.E. England Attachment: UNID_TA_0400z_17
Here's an earlier fragment from 0500z on 14th Nov. Could be a "3" or maybe an "O" with QRN. 73, Dave G3WCB IO91RM nr Windsor S.E. England Dear LF, I copied this fragment at 0400z this morning on 137,
Ah, it was XGJ....thank you for the confirmation! 73, Dave G3WCB IO91RM nr Windsor S.E. England --Original Message-- From: [email protected] [mailto:[email protected]
Hi, Warren Fragments of XGJ were received here at 0300z this morning. Screenshot attached. 73, Dave G3WCB IO91RM nr Windsor S.E. England Thanks Dave, Nice capture, condx down somewhat from last week.
Dear Andy, LF I did a quick search through Eurocall, and found 23 "Poole"s, but no RHM Poole, which is a bit surprising. R is for Ranulph, by the way... Short biopic of RHM Poole contained in the pap
Ed, LF, Good QRSS10 signal from RU6LA at 2200z this evening (Copied in QRSS3) 73, Dave G3WCB IO91RM nr Windsor, S.E. England Dear LF group! What's traces on 137.778,7 kHz at my argocaps - signals was

How about QRSS on three closely spaced frequencies at once, perhaps? 73, Dave G3WCB Dear Gary, LF Group, Quoting from the Propagation chapter of the Admiralty Handbook of Wireless Telegraphy 1938 edi
Paul-Henrik, LF, 136.35 kHz is fine for me, it's probably just that the conditions may have changed. I'll continue to monitor 136.35 for the next few hours. 73, Dave G3WCB IO91RM Hello Dave, LF Thank
Paul-Henrik, LF, I was definitely seeing traces of your signal around 1900 utc before you QSYd. See attached screengrab. No sign ot the QRSS3 on 136.35, yet. 73, Dave G3WCB IO91RM Danke Markus! I'm s
