Welcome to my new Website!

My name is Eric Silverthorn and my amateur radio callsign is NM5M.  I was first licensed in 1976 and am a CW and contesting enthusiast.

For HF I use a pair of Elecraft K3's along with two Winkey USB keyers.   My station is configured for Single Operator 2 Radio (SO2R)  two keyboard operation. 

Heathkit SB1000

I purchased my Heathkit SB1000 amplifier used.  The case needs repainting but otherwise it is in good shape.  The bandswitch knob was replaced with something I had in my junkbox.  I only use the amp occasionally and run a maximum of 400 Watts.

I live in a deed restricted community so I have to use indoor antennas on 6 meters and up.  
My HF antenna is a stealth dipole that lays on my roof for 80m, and a Cushcraft R6000 for 10-20m. 
On 40m I use a homebrew short vertical, 25 ft that is center loaded with two elevated radials.

Although I am not active on UHF and above the following link will take you to a few projects that I worked on.  Project Photos

Ham Radio has been a very important part of my life as it directed me into a technical career.  I own a company called Semaphore Mobile which designs custom application software for handheld devices such as iPhone, Android.  Semaphore Mobile also produce software and hardware for for IoT and industrial communication systems.
