Hello Gary and LF, I'm sorry I wasn't available last night to try some decoding tests myself. I saw the RTTY traces on the grabber as I was heading out for the evening. I will certainly put together
Hello LF, I've just set up a new web-hosting account, seperate from my ISP's "free" webspace, as I was frequently running out of space! The new URL is: http://www.gm4slv.org.uk The grabber is at http
Fantastic news Dave! Will leave at 5W until 18:30 then QRP to around 1W or approx 5mW ERP - should give an indication of your own signal strenght? Cheers -- John GM4SLV IP90gg Clousta, Shetland
Thanks Graham.... so that's what narrow shift RTTY sounds like.., I'll try to decode some now I know. Looks probable given the audible strength of it. John
Hello LF, I've been seeing/hearing sequences of 5 long dots (or are they dashes?) on 503.6 on and off all night. Difficult to know if there's been any ID on them, but not heard any on the odd occasio
Hello LF With the current good conditions for transatlantic signals I've extended the frequency coverage of the grabber. It now covers from 501 to 508kHz. The AR7030 has a 9.5kHz IF filter which seem
Hello FL, Doen anyone know the source of a CW ident I can hear on 503.95 sending "WC WC" ? Just noticed it on the grabber and can hear it reasonably well by ear. Seems to be fading up in strength at
Thanks Graham, This is an interesting discussion, but I think we're seeing things from different perspectives, since you are used to groundwave and skip-zones and such, whereas I'm in the strictly "D

Hi Gary,LF, Hearing your slow CW ident and long dash quite nicely up here. Will email a sound file direct. Cheers, John -- John GM4SLV IP90gg Clousta, Shetland
Undoubtedly I was and certainly I have. Your snide comments aside, I'm referring to your recent reported measurements and optimisation of tuning components to achieve good drain waveform as recounted
that all depends on your software! gMFSK has the choice of 45 or 45.45 There are just as many errors (ie lots) whichever speed I choose. The noise seems to be wrecking the decoding despite a reasonab
Hello LF, Ray, Chris, Just had a listen and GI3PDN is RST539. Band noise extremely low so fully Q5 despite being very weak, as long as I use the external tuneable pre-amp. Also hearing GW4HXO calling
Hello Pat, LF, As an experimentally minded person I do of course keep an open mind on these matters, and conduct regular trials to determine which varietal gives the best results (both for soldering
Hi LF,Gary, Just had 4 successful 100% decodes in a row - timestamps (per your data) 14:54, 14:57, 14:59, 15:02 No...wait.... number 5 just printing 100% too at 15:04 this is too easy John -- John GM
Hello LF, I've just been adding a few sound clips to my web-pages of recent signals received. I keep forgetting to record stuff, but have recently captured G3LDO working G3XIZ, GW4HXO at around 1500
