CW Net

MARCO members are encouraged to check into the CW net convening on 14.307 MHz one-half hour before Grand Rounds. This is intended to be a slow-speed net open to all interested participants. Danny Centers, W4DAN described the net operation: CW interest has increased within the last six months among many of the MARCO members.  The number of check-ins before the SSB net on Sunday mornings has increased.  There are several more that listen, but are reluctant to check in because their comfortable CW speed is slightly slower than many that are regular and have checked in for years.  While interest in CW is on the upswing, and we have the potential of increasing participation in the CW net, maybe it is time to organize net procedure to accommodate all comers equally.  If a formal roll call is implemented at the beginning of the net to recognize everyone that wants to check in, an efficient and orderly net will result.  After all have checked in, then declare it a free net for comments.  To oblige those that prefer slower operation, care should be taken to call the net at a slower than usual speed until everyone eventually gets up to speed.  This would encourage more check-ins.  After a fashion those new to CW net operation will become confident and comfortable with higher speeds.  Of course, late check-ins should be listened for and permitted even after a free net has been declared. There is a good potential of having a very successful CW net, but maybe we should have a little organized direction.  VE3OQM has served as CW net control for many years.  WB6OJB has done a great job of picking up the net when Bob was not on frequency or could not be copied.  I would suggest that Bob could call CQ MARCO de VE3OQM QNI.  As soon as he...
