[ct-user] CT.989.002 - CW Paddle support

Forgive the ignorance of this appliance operator but "pull ups" I gather 
are resistors already in place on numbered lines...

Any halp?

Any recommendations on buying "extended" shells capable of housing these 
additional resistors?

Sounds like a cottage industry is out there for someone willing to 
produce these enhanced LPT connections.  Keying line, Paddle line, PTT 
Line.  Perhaps with ferrites already on the leads, etc... is W1WEF still 
fabricating keying interfaces?

Yes, only 34 days until the Florida QSO Party!  http://www.qsl.net/fqp/
