I'm active on AM and CW.

I currently hold:

  • Extra Class Amateur Radio License
  • Commercial Radiotelegraph Operator License
  • GMDSS Operator / Maintainer License
  • GROL with Radar Endorsement

These are a few recent pictures of my shack.  

The picture below was my AM station that I had in Massachusetts. Pretty much everything was homebrew. Next to me was my single tube AM transmitter and linear amplifier for 75 meters. The rack holds a second AM transmitter.  Everything has since been scrapped for parts.

Massachusetts AM Station

This picture was taken during construction of the transmitter in the rack.

At the ARRL Headquarters on 1/3/2011. Left to right is our ARRL tour guide George Carbonell N1RMF, ARRL CEO David Sumner K1ZZ, my wife Angelica and me.

Here's my 40 meter Class E RF deck using a single MOSFET.  Carrier output is 50 watts, and it's driven by a DDS VFO.

Next is my 8-FET 75 meter Class E RF deck.  This one is also driven by a DDS VFO.  Carrier power is 400 watts.

Here's a closeup of the driver and MOSFET assembly.

The rack below houses my 20 meter station, which I run at 500 watts.  The Heathkit DX-60 is frequency controlled by a DDS VFO and drives a homebrew single 3-500Z linear amplifier sitting in the bottom of the rack.  You can see the tube glowing in the viewing window.

Next is a portable 75 meter, class E AM transmitter.  It runs 100 watts carrier and is driven by a DDS VFO.  Shown in the cabinet is the power supply, audio amplifier and modulator.  

An inexpensive but very capable and portable receiver is the SoftRock Lite II, seen below which I've changed the crystal in order to cover the 75 meter AM window.  Connecting it to a tablet makes for a completely battery powered combo.

If you work me 20 meters QRP, this is the rig I'm using.  It's crystal controlled, puts out 5 watts and has a good old fashioned mercury keying relay.

My station receiver is an SDRplay II.

Everything in the shack run off 120 volt outlets.  It makes things much easier.
