I will like to acknowledge the following people:

First and foremost, to my wife, TERESA, for her unconditional love throughout the years and for supporting this wonderful hobby.

To my children, Maurice and Rafael (KC3GEO), hope your dad had done a good job raising you. I LOVE YOU VERY MUCH.

IN LOVING MEMORY OF MY FATHER ENRIQUE CENTENO (1910-1984) AND MY MOTHER CARMEN BAUZA (1928-2008) (NP4NR). Both supported my hobby in every imaginable way.

To my sister Lourdes, KP4LCB, for putting up with your big brother and for your love.

IN MEMORY OF MY MENTOR AND ELMER, CARLOS HIRAM RIVERA, WP4I (SK). He taught me everything I know about Ham Radio and CW.

I will like to acknowledge WP4AOO, Jose Alfonso, for all of the "Work of Love" to the hobby and the countless people who have become Licensed Amateur Radio Operators through his teaching. My heart goes out to you and your family. My prayers to you and your family through this most difficult times in your life. Get well soon!!!

I will like to acknowledge KP4IM, Jose, for teaching me everything I know about ESSB and for his friendship throughout the years.

To N3COB, Glenn, thanks for being such a good friend and for inspire me to try Satellite Amateur Radio Operation.

To Toñito Algarin KP4DE, Daniel Hernandez KP4BD, Cheito Roldan KP4JAR and Pedro Labayen KP4DKE. Thank you so much for your hospitality and friendship to my wife and me during my recent visit to Juncos and Utuado, Puerto Rico.

First licensed in the mid 70's (c. 1975) as WP4AFV. Got my Extra Class ticket in 1982 (FCC Certificate # AE-22-83) and callsign KP4GB. I received the new Vanity Call KP4N in 2012.

Active from KP4-land from 1982-1985. Portable operation HP2/KP4GB from 1987-1989. Inactive from 1990 through 2007. Active once again from 2008 through present from W3.

My favorite modes are CW and Digital (PSK-31, RTTY) and enjoy ESSB from time to time.


KP4N-L Echo Link Node in the OLNEY, Maryland area is (INACTIVE).

OLNEY, Maryland now has its very first EchoLink node available over the air. Sponsored by KP4N, N3COB and N3PZ, this node, number 780477 is available for use by any amateur operator within range. Local hams are encouraged to scan and monitor this node you never know when a QSO will connect, so let's make sure the world finds some activity in our area.

When using the 2 meter access on 146.550 with PL Tone 88.5, you do NOT have to be registered with EchoLink to use this service! You do NOT need an internet connection. It does not cost anything. All you need is the node number of the user you want to connect with (which is of course available online at www.echolink.org ), or simply reply to anybody that opens the link remotely.

There are some shortcuts listed below, and frequently used nodes can be programmed into the system with shortcut access. Up to 10 different nodes can be connected at the same time for a mini-conference; this can be expanded by using one of the over 200 conference nodes (similar to IRLP reflectors).

Currently, the radio is set to 146.550 simplex, but this is subject to change.

EchoLink Etiquette

  • LISTEN before keying up or entering DTMF commands
  • IDENTIFY your station before invoking commands
  • Enter 08 to find out if link is connected to someone already
  • Don't disconnect a connected link unless the other parties are finished
  • Remember this is a Simplex Node, not a repeater. There could be a distant station using the link that you can't hear.
  • Keep transmissions short. There is a 200 second timeout.
  • Allow a slight delay after keying up before speaking
  • Leave extra space between transmissions to account for packet delays
  • Don't key up rapid-fire after an internet transmission (like I do), the RX won't trigger for 1 second and you�ll be talking to yourself
  • Close the link when finished (using #, or ##), and identify your station as clear
  • RESPECT the system. All connections will display my callsign to the remote system.
