Comments on recent e-mails.

1.  I cannot comment at all on the ARD receiver, never having seen one.  However I would agree with the statement that a 500Hz filter is too wide.  I have been using a 350Hz filter on hf for years and accept its higher loss.  On hf it is the accepted norm, on 136 we need the filter as narrow as we can get it.  I can understand those who have a quick listen on the band with a ssb filter - with DCF39 it is not surprising they hear no amateur signals and quickly lose interest.

2.  I am always on the band listening fo QSOs between 0530-0630z.  Apart from one or two regulars there seems to be little activity at that time, even at weekends.  Can I remind all that this is an excellent time for lower band noise levels.  In fact the gear is on all day during the week, although I seldom have qsos at other times because of business commitments.

3.  I note with interest the G3XTZ beacon on Wednesday - I must have missed the announcement that this was going to be on.  However I thought QRSS activity would normally be at the top end of the band.  If it is necessary to transmit QRSS outside that section it would be most useful to identify in normal CW at suitable intervals (test beacon de G3XTZ qrp...).  For those of us not into the QRSS scene it is not possible to distinguish between that mode and someone tuning up, and I waited with bated breath for him to start listening for calls.
