Hi Dave,

Thanks for your comments, hopefully the antenna improvements I implemented for 500 kHz have also improved things here as well. Though biggest change for 137 are the "improvements" I made to the loading coil.

You can see the progress on my web site at http://myweb.tiscali.co.uk/wgtaylor
in the antennas pages.

Hi, Gary.
You must have made some antenna improvements since I last copied you on 137...you're putting out quite a strong signal.
 
Regarding rge ROS signal, it looks quite wide, but the power density is low, and there's plenty of "white space" between the dots. It would be interesting to see what the spectrum would look like with 5 or 10 stations "stacked" on top of each other.
 
Not that we ever get 5 or 10 stations on 137 kHz...:-(

Hi Dave,

Yes, that is my ROS signal, the MF-1 mode is no more than 100Hz bandwidth.

Thanks for picture.

Gary,
 
Is this what ROS looks like?

Hi LF,

My ROS MF-1 beacon is transmitting now with 3 minute timer.

Frequency is 137.500 kHz (dial 136.500 kHz USB), reports & QSO attempts very welcome.

ERP about 50mW.
