Greetings fellow radio operators!

PRR Position Light Signals

Working PRR position-light signals on my railroad.  To see them working: http://youtu.be/qxmYF0r-9uk

General video with train backing into yard as two run around main tracks: http://youtu.be/TxHtg6BCVgU   (more stuff below)

I have been licensed since 1986 and came in as a Novice. I was 26 years old then! One of my co-workers was a ham and he gave me my license exam during a lunch break one day! My QTH is just outside of Philadelphia, near the Philadelphia International Airport.

I am new to CW so thanks to all of those who have been very patient with me. I'm still learning to send with my straight key and not get "glass arm" or loose track of what I wish to say while keying. I enjoy CW very much and wish I had pushed my self harder to properly learn it sooner. I thank the hams at CWops and SKCC and FISTSfor offering good CW elmering programs. I enjoy working other ops new to CW. I have been doing most of my HF work on CW and really enjoy it.

I am a member of the Straight Key Century Club, #11080, FISTS #14610, and my interest in CW goes hand in hand with my other big hobby which is railroading. I enjoy freshwater fishing as well.

I am happy to confirm contacts with other stations and short wave listeners provided I have them logged. I will send QSL in mail, via bureaus, e-QSL and LoTW.

I try to upload logs to LoTW and eQSL as soon as I can but once in a while I miss one as I use a paper log and convert manually for electronic confirmations. If you sent aQSOto LoTW and have not received a confirmation, please e-mail me.

My other hobby interest, when the bands get lousy, is model railroading which I've been doing since age seven back in 1967!  Below is a small snapshot of my 7' by 12' HO scale model railroad.  I handlay my track with individual wood ties and even make my own track switches (turnouts) out of rail stock.  The rail comes in 36" lengths.  I created a small jig to make the turnout frogs and used either a Dremel tool or a hand file to shape the rails and solder together, using the same tools to shape the point rails.  You can see three of my hand-made position light signals -- one a high signal and two low to ground "dwarf" signals.  The signals do work -- I use a desktop computer and software that I wrote using PowerBASIC for Windows.  I run it under Linux, however! 

 

Below are some recent pictures of the layout still in progress.   My signals are hand-made out of brass stock and the lamps are micro LED's.  I light the LED's by having the computer controlled logic controllers complete the circuit to ground using logic "high" which turns on a transitor to sink the LED current.  The signals themselves, being brass, hold the 5v positive voltage.  There are dropping resistors in both negative and postive feeds.

USRA 0-8-0 and signals

 

This is one of four logic controllers in the system.  The vertical boards are track circuits which detect train position.  The computer power supply in the back powers everything.

Below is the manual controls for the switches and signals.  The computer also operates the switches similar to the signals as the switch machines are stall motor machines.  Plus and Minus 12v go to either side of the motor and one side is grounded to make the switch move.  This is a representation of actual controls found on railroads.
