I made a rather serious effort in the Illinois QSO party today since I used to live in IL and know a few of the operators in the contest, plus it is only an 8 hour effort-but I wish they would move i
Hello John, In my case I use several things. I have two noise cancelling units: QRM Eliminator by SP8RSM JPS ANC-4 These are no DSP but rather X-Phase type. I owned a Timewave DSP599zx which worked o
John I have to say that 80% of the noise that impacted me on the low bands (and even 2M) was in my house. The worst was a Cisco switch that wiped out from 1Mhz - 240Mhz. It was the switch I was using
John notes that he had many noise sources, not just one. A phasing unit isn't going to help him. That's a job for reduction at source, or DSP. 73, Drew K3PA Send CQ-Contest mailing list submissions t
I've had that situation. Even if you have multiple, depending on the strength of the EMI, it usually helps a bit, since at least it will eliminate one of them, or two in my case (I side chain the bot
Not for your neighbors on the air when you're running SSB -- its IMD generates splatter on SSB and clicks on CW that make your signal 3 times wider than it should be. I discovered the SSB problem whe
I have to say that 80% of the noise that impacted me on the low bands (and even 2M) was in my house. Yes, the stuff in our own homes is often our worst enemy! I spent a few days going around with a H
Thanks for the feedback so far. Those videos are rather impressive. Other than the FTDX3000, are there other radios out there that have very good noise reduction circuits good at reducing the fatigue
Not a super modern radio, but I was very impressed with the Elecraft K2 DSP daughterboard. It had an uncanny ability to pull very weak signals out of noise. It was also quite good at removing man-mad
