73 kHz band is going to be difficult from= my =0A= preliminary tests. =3B Seems to be a lack of skywave. =3B I thi= nk =0A= skywave is going to be rather scarce and =3Bbest I am doing so far = is out =0A= to Kansas but it is ground wave am sure. =3B Got to get the ground = system =0A= rolled out here soon as lawn mowing ends. =3B That should help = =3Bto =0A= give me more field strength on all the bands. =3B Going to try 73 = =0A= periodically and see what shakes out!
I have worked PA0A on CW by ea= r =0A= last winter on 500. =3B Yes our 500 licenses go down to 470 region.=  =3B =0A= In winter we should have no trouble working CW by ear am sure and will = be =0A= looking forward to it as you would be even further away from me than = =0A= PA. =3B I also worked into N. Ireland and I went to SSB and was hea= rd and =0A= worked Finbar=2C EI0CL [I forgot the suffix of his call] cross mode as = he has =0A= no SSB authorization. =3B Jay=2C Warren and I work regularly Sunday= evenings =0A= on 510 upper throughout the =3BWinter months.
I see no takers fo= r =0A= 73. =3B Gary has a grabber on 73 for us and using QRSS 500 spec lab= and I =0A= tried last nite but never saw a trace. =3B With ground system out t= his =0A= Winter his grabber may be a winner-Bob

Hi Bob=2C = =0A=

Success! :-) Welcome! :-)

Sorry i can't receive on 4000m= here =0A= since my receivers are mono band homemade DC converters (for 137 kHz an= d 472 =0A= kHz) and direct sampling receivers at 0...24 kHz.

But=2C i remem= ber you =0A= were the strongest station on MF (is that 472...479 kHz for your licenc= e?) =0A= last season. Are you a CW man as well? Do you think it is realistic to = try =0A= for a TA CW QSO? If=2C then it could work in november to february. So f= ar i'm =0A= only getting sporadic WSPR-2 decodes at WD2XSH/17. My WSPR signal is QR= P =0A= though. At least VO1NA copied my signal in GN37OR last year...
Worth= a =0A= try? I'm continuously doing overnite WSPR-2 tests on 630m.

With Stefan's help I seem to have finally = made it =0A= into the group. =3B I am Bob Raide W2ZM with exp. =3B license= 's for =0A= 500=2C 137=2C and most recently 73 kHz band.
I am ready to fire u= p on =0A= 72.401 with Qrss 60 if anyone is interested to try for a capture =0A= tonite. =3B Or I can change to 137 if no one is interested in 400= 0 =0A= meters.
