Anyone know if Gus is planning to be on 500kHz WSPR tonight? I'm hoping that he will (at last) decode me if he does appear. BTW, two new reporters this evening PA0AM and G4CAO - thanks to both. 73s R
Dear LF group, After running beacon WSPR night 6-7 November with only 10 mW ERP (125 mW) TX power on 500 kHz it gives me great surprise, that a very long range can be achieved with extremely small p

Dear all, Very encouraged by my results at 500kHz, I'd like to try some "low ERP" WSPR tests on 136kHz using the same small antenna and transverter (slightly modified). Ideally I'd need stations lik
Thank you to all the people who have given me advice, both via this group and by direct email, on FET PAs for 500kHz. There has been a LOT of good information and too many emails to reply to everyone
I've been using a single IRF510 FET PA stage on 500kHz and it produces around 6-7W of RF. But, when adjusting my antenna I've managed to damage several devices now. I think the stage is running some
G3XIZ is a good signal calling G0NBD on 501.6kHz RTTY. Not yet heard M0FMT. 73s Roger G3XBM 2009/11/29 M0FMT <[email protected]> Jim FYI G7NKS G7NKS THIS IS G7NKS AT IO92UB IO92UB 200MW ERP OP JIM
If anyone's about, I am trying to use a new fangled digital mode (it's called CW) on 500kHz. Calling CQ around 501.7 and looking for any calls. Have heard M0JXM calling CQ but he did not hear me. 73s
Will leave the 500kHz 1mW ERP WSPR beacon running through the night at 10% TX and we'll see what happens. Any reports, especially from DL or SM would be great. 73s Roger G3XBM -- -- http://g3xbm-qrp.
Hi John (et al), Yes, I managed to get it to match on 500kHz and, despite what appeared to be a lower antenna current, it got me to Germany and France. Today I am going to try for some CW QSOs. G3XIZ
Today I modified my 500kHz antenna. The 28MHz halo up at the top of the 5-6m vertical section (which was the coax feed to the 28MHz halo) was removed and replaced by a spiral inductance/ top capacity
Hi All, SM6BHZ heard me, at last, on 500kHz WSPR at 0556z this morning, so my best DX has now gone up to 951kms with the tiny station. 2009-11-08 05:56 G3XBM 0.503896 -26 0 JO02dg 0.002
Mike (et al), As an owner of the 1st edition of LF Today may I thank you for this most helpful little book; there has been much in it that I've enjoyed and used as sources of information. I do hope a
Andy, Thanks for the quick feedback. The 500kHz antenna is a 5m long vertical with a spiral top hat. It is fed via a (thickish) ferrite rod wound with the required inductance to resonate and this is
Now I am unclear what really constitutes a WSPR QSO. Does me getting a WSPR database report from XX3XXX and he getting on from me at much the same time on the same database constitute a QSO? Or does
John, If you manage to hear me on 136kHz I shall eat my hat. ...but then I nearly said that last time about 500kHz!! 73s Roger G3XBM 2009/11/17 John P-G <[email protected]> Roger Lapthorn
