Hello Paul,

Does your sferic blanker fill the gap with zeros, or with interpolated values, 
or does it eliminate the gap? Or other? 

I have been planning to make a Matlab impulse post-processor that fills with 
interpolated values for use in noisy locations; wondered if the SpecLab sferic 
blanker already interpolates.

Looks good Stefan.  I'll be looking for your signals.

I assume the daily 100 character 5170 transmissions will be off until Monday.

Currently I'm testing some changes to the sferic blanker.
I can't really improve on the settings I've been using for years at 8270 but at 
lower frequencies it is possible to gain up to an extra 2dB.  I mentioned the 
other day about the use of a separate channel for triggering. Also I've altered 
the noise floor tracking, using an asymmetric time constant to good effect.
