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.

I am a member of FOC (#2121) and CWOPs (#974) I also am an instructor (advisor) in the CW Academy (CWA). To learn more about the CWA and CW Ops visit http://www.cwops.org/cwacademy.html
