There is a big difference between "energy on opposite sideband" and hearing the opposite sideband. If you switch to the opposite sideband and can clearly copy the intelligence, then the issue is sideband suppression. If you hear unintelligible audio from the offending signal, that is splatter with many possible causes, one of which is IMD in the exciter, amplifier, or both.
ALC is frequently abused with the offending op receiving great audio reports. I find many who never monitor ALC while operating SSB. Few ops give accurate audio quality reports today, much less pay attention to TX bandwidth when providing reports in spite of the proliferation of SDR's and panadapters. Most don't know the difference between RFI in the TX audio chain and an over-driven signal. We need to mentor our brethren to help guide them in the right direction. While some might consider this nitpicking, ours is a service based on science and facts. However, science and facts are too often ignored. I use screen captures from my P3 when pointing out broad signals. Half of the offending ops don't have an e-mail on QRZ.com. Half of those who do are surprised to learn of their transmitter bandwidth "abuse." A significant portion of those don't care and are offended. Fortunately, that is rarely the case here. 73, Bill, K8TE "Sadly, many of those are splattering so wide that you can hear them on the opposite sideband. Unfortunately, a report of great audio does not mean great IMD performance." -- Sent from: http://elecraft.365791.n2.nabble.com/ ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
