All Systems are Go – QSD Radio

Over the weekend I installed the 8-pole audio lowpass filter as well as a temporary 40m band-pass filter at the front-end. Already I can hear the difference in bandwidth and absence of QRM from off-channel signals. I haven’t rigorously tested it yet, But I’ll do that this weekend.

I listened to a contest on Saturday using a little 3″ speaker laying on the bench. Sensitivity seems comparable to my TS-450 and audio quality is good, given the compromise speaker. Sunday, the band was dead until evening.

I wrote a little dissertation on my experience with this rendition of Tayloe detector. You can find it here:

More tests and specs to follow.
