G0MJI - 4m Wspr

Hello, thank you for finding your way here.

Wspr on 4m is a little different from Wspr on other frequencies. This is due to a number of factors, not least the scarcity of multimode 4m transceivers at this time. It is a little less 'Plug 'n' Play' than on the other bands. As ever rumours abound that a new 4m Multimode is on its way (Okay, the Icom 7100.) In the meantime 4m Wspr remains an interesting challenge.

Here are a few things I have learned whilst trying to put out a Wspr signal on 70mhz.

I hope to spot you soon...

1) Why 4m Wspr?	5) Modifications To The Spectrum 4m Transverter For Use On Wspr
2) What is possible?	6) What Is A Weak Signal?
3) Frequency issues	7) Using The Spectrum Transverter With A Flex 1500 - Yes You Can!
