Received a nice card from Tom WB2ILA concerning the MRCA Sunday Night CW net. The net is now held at 20:30 EST and the frequency is 3558 kc. The old frequency was 3570 kc- I have several sets with the older frequency of 3570 so I need to change.  I  did check AF4K's site and he has miniature crystals available on 3558 which are available depending on your "crystal current" requirements. 
               Anyway a nice reminder from Tom,  very professional.
