[Elecraft] What crystal filter do you use the most?

I am not DW but I think I qualify as etal!.  I have been doing CW since I was a pup and I am older than Hector.  I started with a BC455 with no crystal filter and the bandwidth of the receiver was about half the novice band.  I now have a K3 with 500 and 200 CW filters.  I sometimes use the 200 for rare DX that is in the noise with lots of QRM, but most of the time I set the bandwidth to about 500 hertz.  The 500 hertz filter suits me fine.  When I use an older rig without digital bandwidth and with a 500 hertz filter I am real happy.  With the K3 I am happy with about 500 hertz band width for rag chew contacts.  It does not mother me to hear three or four signals unless they are about the same strength and about the same tone (frequency).  My K3 has standard 2700 hertz SSB, standard 500 hertz CW plus an additional 200 hertz filter.  I think I wasted money for the 200 hertz filter that I seldom use and I can't document any QSO that I required the 200 hertz filter to make the contact.But I am easy to please and was quite happy with the BC455 and a couple of crystals in 1956.   Willis 'Cookie' Cooke,TDXS Contest Chairman K5EWJ & Trustee N5BPS

Hey DW etal,

I noticed that you like to get on 40 and 30 at sunrise......I may try 
that if I can get up early enough! Have you read the article in the last 
QST about the 3 myths about propagation, notably on ionization at 
sunrise? It may be of benefit.
