Seems to me that measuring ERP at LF is a bit of a problem. On here I have read comments referring to a stations ERP by various operators : 'Estimate', 'Guess', 'Approx.', 'Reckon I'm fairly close to
Hi All, Gary: Could the undecoded signal you saw have been G3XBM, according to me he was on 503933? WSPR decodes here last night from G3XBM, G4JNT, G7NKS, OR7T and SM6BHZ. Horst: Agree with most comm
OK Brian, thanks for the info. Yes, I realise the efficiency will be a bit less. Seems different people have had quite different experiences using AF techniques/ready made amps etc. Thanks, 73, Chris
I also listened to CW QSOs between G3LDO, G3XIV and EI0CF on the evening of 29th. September 2009, all excellent signals, 100% copy. Great! Recorded it to listen again when bored with lack of CW activ
Hi All, MANY thanks for all the comments and links about using AF amps. I have followed up all the links and taken on board comments. The diverse observations/results have made fascinating reading an
Hi All, Just started constructing TX for 136kHz, noticed Maplin do a Velleman audio PA kit that is rated at 200W (100W RMS into 4R). OK there's no mains transformer or heat sink, but reckon it's good

Hi All, Does anybody know who was sending 'Y' last evening just before midnight UTC on approx. 137.778kHz, please? Thanks, Chris, G4AYT, Whitstable, Kent, JO01MI. Attachment: capt00002.jpg Descriptio
Hi All LFers, Does anybody know if someone is co-ordinating, compiling a list, or whatever, of the numerous errors in the RSGB publications 'LF Today'? I see errors in the book first published in 200
Hello Roger, You are right about the transformer thing and the calculation being incorrect, however, you will be pleased to know this has been put right in the second edition. I totally agree, these
Hi Mal, Some while ago when I commented a strong signal in the band and in beacon mode was causing me problems, you quickly told me I was talking nonsense, saying I wouldn't have such problems if I h
Hi Mike! I'm still at your old QTH, trust all is well with you. Will make you a list of some errors I have spotted and foward it to you in due course. Even some of the page numbers in the 'Contents'
Hi Mal, I agree with your comments about WSPR QSOs. Also pleased to see the renewed interest/increase in activity on 136/7kHz. Earlier you said you had 1W ERP on 136, I am interested to know how you
