Confused about pre-select filters and WIDE receive mode

David Salomon

My goal is to be able to use a slice for ALE scanning, bypassing all filters so the rig is not engaging and disabling filters 2 to 5 times a second.

My understanding about filters is that when the slice is in WIDE mode, pre-select filters are disabled.  However, when I use MARS-ALE to scan frequencies, I still hear relays clacking as the frequency moves to different areas of the spectrum.  Note that I am scanning frequencies outside the ham bands.

Did I misunderstand how filtering works on the 6600?  Is this possibly an issue because I have the MARS filters installed?  Is there any way to simply bypass all filtering until the radio is put in transmit, then disengage the filters on receive?

If I 6600 will not work for this application, I have another question.  Is there a way to have the radio frequency set from external software ONLY when it goes into transmit?  My reasoning for asking this:  I can set up MARS-ALE to scan and receive via another SDR, but key the flex when an active frequency is found.  However, doing this currently will (obviously) transmit on whatever frequency the 6600 is set to, which does me no good.

Any thoughts and comments welcome.

Can't help you there as 160 is the only HF band I do not operate, so never tested there.
