Dear LF Group, So, as far as trans-atlantic band-plans are concerned: It appears that there isn't actually a common frequency range that all stations on both sides of the Atlantic could use for WSPR
Dear LF Group, I still haven't replied to Fritz Raab, W1FR, regarding the WD2XSH US band plan which he is apparently coordinating - you may remember I posted the US proposals, which he sent me, a cou
Dear LF Group, Thanks to all for the overnight reports/decodes. I also set my RX to listen for WD2XES on 137.577k, but no decodes here - perhaps not suprising considering the level of QRN! Cheers, Ji
Dear Roger, LF Group, The "WOLF GUI" software can be downloaded from http://freenet-homepage.de/dl4yhf/wolf/index.html. Intallation is just a matter of unzipping the zip file. If you then run the WOL
Dear John, Jay, LF Group, I started a bit late last night at 0124utc (don't ask...), but again got consistent copy of WE2XGR/2 and /3. /2 decoded between about 0350 and a little after 0534 (about sun
Dear Laurence, Roman, LF Group, I shut the beacon down at 0446utc this morning. The frequency was 503.975kHz as advertised. Thanks for the overnight reports, nice to see spots from W1TAG again and fr
Dear Laurence, LF Group, The 468kHz frequency does seem to be slated for Chinese Navtex broadcasts - apparently 424kHz is being used for Japanese language Navtex too. This seems to coincide with a ge
Dear Jordan, Roelof, LF Group, I have used a very similar circuit to the one in Roelof's schematic for some time (it is in the RSGB's "Radio communication handbook", and "LF Today"- I should declare
Dear Roger, LF Group, I intend to run the WOLF beacon again from around 1900utc onwards this evening Cheers, Jim Moritz 73 de M0BMU All being well I am now ready to RX on WOLF on 502.5kHz (USB dial f
Dear Graham, LF Group, As the European allocation looks to be wider than the Uk, are we expecting the UK 3 Khz allocation to remain as is, if and when the band is formalised ?, in which case loosing
Dear John, Jim LF Group, Oddly though Jame's twin spots of Jim are 100Hz apart: M0BMU 0.503944 M0BMU 0.503844 My signal is on a nominal 503840 centre frequency... I think what has happened is that, i
Dear Graham, LF Group, If an error in sample rate was causing the error in the transmission timing, it would also lead to an error of the same percentage in the audio frequencies being generated duri
Dear Roger, LF Group, It is interesting to make an estimate of what G3XBM's ERP might be... The noise level at M0BMU during relatively quiet daytime conditions I estimate to be of the order of 3uV/m
Dear Dave, AC 97 (http://download.intel.com/support/motherboards/desktop/sb/ac97_r23.pdf ) specifies 48kHz as the basic, obligatory sample rate for compliant sound cards, so yours should certainly be
Dear Jim, LF Group, Me too. I am getting 3 traces (!) from Jim M (he is 9+10 and audible!) and a biggish one from Gus too I am seeing low-level (about -25dB) sidebands on your signal at +/-50Hz and +
...I should have said that it is on 503.975kHz, 502.4k "dial frequency" -- Original Message -- From: "James Moritz" <[email protected]> To: <[email protected]> Sent: Sunday, Sep
Dear Chris, LF Group, Thanks for the reports on the 136kHz signals. ...I am having difficulty in seeing the point of some of this when there is little in the way of exchanged information between stat
Dear Andy, I would suggest a frequency between 503.825 and 503.900, to avoid the QRM around 504kHz some people experience, and give a bit of tolerance for receiver frequency errors, which are sometim
