I did not ask a question about filtering !!!!!!!!!!!!!!!!!! What I said was why use SSB mode which is 3 khz wide for a 6hz/200 hz wide signal when one could take advantage of the receiver narrow CW f
If you could read you would do some research at K1JT's wonderful website: http://www.physics.princeton.edu/pulsar/K1JT/ Joe has laboured for many a year on similar projects and has written much about
Having used practically every mode both as a radio amateur and commercial operator morse code (CW) is the most effective method for a radio amateur where only a minimum amount of information is excha
Mal The answer is simple in many cases. Why not? I will explain. You can use a narrower filter if you like, it would have to be 200Hz wide to allow the reception of all WSPR signals in the range of t
If recent published info is correct, this specifies a bandwidth of 6hz why is USB with a bandwidth of 3 khz necessary to receive this transmission. Surely it would be obvious that CW mode was more ap
Hi Mark A sensible response to my own observations, others seem to miss the poiint and go off at a tangent if it differs from their own opinion. In this context about WSPR I am able to see the other
Hi all, dj8wx is xmitting at 135,975kHz in WSPR mode, pwr abt 50mWERP. RX dial 134,475kHz (USB). No traces of your signal, but another one showed up, about 80 Hz lower... 2240 -21 1.8 0.135896 -1 TM0
Hello Uwe, could you increase your power for just one test, HBG 22 is too strong. F4DTL Nicolas. Dans un e-mail daté du 09/01/2009 20:55:13 Paris, Madrid, [email protected] a écrit : Hi all, dj

Thanks Victor, The signal on your screenshot with the strange "hook" at the beginning is DF0WD (operated by DL4YHF). Markus DF6NM noticed me in a PM about the effect. I don't know what causes it yet,

Shouldn't they be marked as such by the program ? I have seen in the past some rows received by WSPR with the tag (bad msg)... but maybe it catches only some of the errors... Dear Alberto, LF Group,

Hi all I am getting strong traces of the wspr signals on 500 khz but only some decode, obviously the system is working otherwise I would get no decoded material at all. There also seems to be delays.
