From Dave G3YMC

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.
