Hi Roger!
=20
Tnx for your point of view. I do not disagree you but... ;-) WSPR will giv=
e a good experience of the propagation and what can be done with a given=
 station and thus it can be useful to increase the knowledge of all of us.=
 It will be a good additional feature to LF unless the "real QSO modes" ar=
e not neglected (i know in wspr is also a qso mode). But if many people wo=
uld switch to WSPR instead of the other modes and if it gets boring after=
 some time, because it is rather a communication between computers, then=
 the whole activity would decrease, perhaps.
It is the same with contests on HF: If you want to test a new antenna then=
 you could do say 5 personal QSOs with a real content and discuss about yo=
ur antenna with the others and get a feedback e.g. about the QSB and so on=
. Or, you can do 100 QSOs in a Contest and get 599tu (yes, in wspr there=
 are real rprts, thats an advantage ;-) ) and can say "I worked USA, Japan=
, Afrika" and so on... That is a good way to check where you can be heared=
 but after a while, the 599tu gets boring for the most. Recently, accident=
aly i found the website of GW4ALG who went QRT due to the contests. He mad=
e excellent circuits for amateur radio, also for LF (my Converter was his=
 idea). I do not know the whole story but i can good imagine that he was=
 very active and interested and dissapointed by the trend to unpersonalize=
d "QSOs" on amateur radio...
=20
I  am just a little afraid that now, many people will neglect QRSS/DFCW/CW=
 and go to WSPR so that the activity in the "old fashioned" modes will dec=
rease. I will not follow to WSPR but i am interested in the informations=
 about the propagation on LF, that will be accumulated. I do not say "Let=
 the fingers from this mode", rather "Remember that amateur radio is prima=
ry a communication between humans, not between computers". For QRSS one ca=
n say it is the same but for me it is rather a audible to visible conversi=
on, the human still has to do the work to catch a wanted signal out of a=
 noise :-)
=20
73 :-) Stefan

Dear Stefan,

You are, in the end, correct and I am sure that Mal G3KEV will already be=
 writing his response in support of you email, HI.

However, my own experience has been that WSPR has made possible propagatio=
n experiments and equipment designs which, were I using CW, would not have=
 been possible. Six months ago I believed you needed 50-100W, capacitors=
 rated at hundreds of volts, antennas that resembled a military tracking=
 station and a ground system with miles of radials to get anywhere. Then,=
 with WSPR, I found out that very little was needed: a simple transverter=
 made with a handful of parts, an ATU made with a small ferrite rod and th=
in copper wire, an antenna that is only 5m long and a ground that is, esse=
ntially, the copper pipes in my home. With this modest station I have lear=
ned a lot about MF propagation and had a great deal of real FUN.=20

So, whilst I agree that a "real" CW or phone two-way QSO is a great and pl=
easurable part of ham radio, I do sincerely believe that WSPR, and indeed=
 many other modern digital modes like JT65, JT4 etc have their place on th=
e ham bands of today.

73s and a happy New Year to you.

Roger G3XBM
