Re: My latest MIDI controller opus

Scott ... indeed nice job on the labeling - how'd you do it? I have a Dymo machine here that does the sticky paper labels ... worked for a while on my CMD2A but now some are peeling off... would love to know which tool and tape you used (it appears to be a clear background)

Re: Diversity Operations

Yes - very cool. I played with it on FT8 ... that 'interferer' that i have I think you'd agree is a nasty one. I'd love to find out what is causing it - Plasma TV, grow lights ... haven't a clue ... It is worst on 15 and in that direction covers the whole band with the repetitive nature seen there (...

Re: Diversity Operations

One other comment: just to be clear - this feature is only "local" in nature - in 2 ways: 1) it acts on local noise, not sky wave and 2) frequency-wise it is somewhat narrow in response so one has to optimize at a particular frequency (the one of interest)... I don't know that it is overly...

Re: Diversity Operations

I've not had a chance to look in to how to do it ... besides the fact that there is no audio... so I'll work on getting something better. One reason why I did this is because the only video (on UT) that shows coherent beamforming doesn't show it WITH a signal! So I for one was left asking : but how ...

Re: Diversity Operations

sorry - misspoke there - the noise floor does not go down by 24db ... that nasty noise signal PEAK goes from -90 down to the (new) noise floor at 0-114db. Since these interference signals repeat and are broad the overall noise floor does go down a decent amount ... looking at the video it changes ab...

Scott, thanks for the detail on the switch. It's not a router - it is just a switch (there is a router on/from the incoming Spectrum cable line though).

Just as an FYI and pertinent to the mention of the resampler to 'correct' things.

Same response as before Scott..... operator never doing something stupid like driving an external amplifier with 100W. If you have an amplifier with no protection against gross over-drive it would be possible, without ALC, to make a stupid and potentially costly error. As I've explained ad nauseum t...

Re: My Diveristy Adventures

Scott will I'm sure reply about using the system in general. I have never been able to get diversity to work myself but that is more because the antenna selection is critical. I've not had a reference antenna that picked up the noise as loud or louder and still picked up some of the signal. So I end...
