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. -- Paul Nicholson --
