This EME station map is based on data from the call3.txt database file maintained on the MMMonVHF site. The red dot indicating the location of a station is shown at the centre of their grid.
 
 
I have only included stations that have a 6 character QRA locator and an 'EME' label and ignored stations marked as 'Expedition'.

I recently worked KS but still need the following states to complete WAS on 144MHz EME - NV, OK and VT. If you're active in any of these states, or know of anyone who has 2m EME capability please contact me via the email address on my QRZ.COM page to arrange a sked.

Having been involved in software development for most of my career I wanted to use a toolchain that that was lightweight and low cost to build my own website. After some research I chose Hugo as the static site generator, Amazon S3 as the hosting service and GitHub as the repository for site customisations and content. 
 I spent a couple of hours getting Hugo, Amazon S3 and GitHub setup using…
My interest in radio started when I was around 12 years old, listening to broadcast stations on short-wave using my parents Marconi T21A valve receiver. I collected QSL cards from all over the world for my reception reports and then moved on to listening to radio amateurs on 40m and 20m. 
 I passed the RAE in 1975 and was first licensed in 1979, starting on 2m FM with a homebrew transceiver…

In 2020 I took up CW again after many years and successfully completed the CWOps CW Academy Basic Course in March 2021. 
 In May 2021 I successfully completed the CWA Intermediate Course and now enjoy making regular CW QSO’s. You will hear me mainly on 40m and I occasionally take part in the K1USN SST and CWops Tests (CWT). I am also a member of the Long Island CW Club, a club dedicated…
