WANTED: MEPT Grabbers in S. America, Africa, Asia

Dear Bill,

It Hurts!!.... You have abandoned us visual Beacon Anarchists for the Instant gratification of the WSPR crowd.

Hey, To refresh your memory, Your the one that got me started in this Visual MEPT World. I listened to your podcast and ordered some 10.140 Mhz Crystals and built my Model 1 MEPT transmitter. After that I was hooked. It has gone on to a model 2 and Now started on a DDS driven Model 3 which is all band and right now is crying out for someone to see it at 160 mW. It has made it last week to VK7ZL in Tasmania 8455 miles and ZL2IK in New Zealand 6917 miles. So, as you can see, I have been busy. One of the really extarodinary things is that we are doing this on 40 meters at 7,104,800 Hz. What would really help is to enlist some more monitoring stations with ARGO Spectrum Analyzers on their computers LISTENING. They are sorely needed in South America, Africa, India and the Far East. I have the belief that my signal at 160mW on 7,104,800Hz can be copied in all of those areas at different times of the day, almost every day. The reason it isn't is there is nobody listening and my little FSKCW signal
just keeps looking for a receiver to hear it.

My model 3 transmitter is a thing of beauty. It can work all bands from 160 to 10 meters. It is completely under the control of an Ardunio processor (A great product of Italy). It controls the frequency, the amount of frequency shift, and the CW keying. It is not quite ready for prime time yet. But work is being done on the controlling software and one of these days, It will be done. Then the visual guys will not be chained by a crystal to determine their frequency. They will merely command their Ardunio to control their Direct Digital Synthesizer to the desired frequency, select the desired mode of transmission and hook up the antenna.

So, Please Mr Bill, Don't abandon us visual MEPT beacon guys. We really need your voice and talents to keep the airways of our 100 Hz of spectrum alive and vibrant. You could hang an extra wire out the window and do both!
