Hi Slava, I have also noticed this, is the robotic sound you are referring to a low frequency sort of "wha wha" sound which modulates along with the normal voice signal.
I have heard this before as well, and had a friend describe it as "typical Icom", which leaves me in the dark about what it is, I add the Icom comment only to help describe the sound, (assuming it might be specific to Icom), not make a statement about Icom radios. I have not found one yet now that I have my K3/P3 combination, which means maybe I need to open up the less than 200 HZ pass band on the K3, which is not going to happen. -- Thanks and 73's, For equipment, and software setups and reviews see: www.nk7z.net for MixW support see; http://groups.yahoo.com/neo/groups/mixw/info for Dopplergram information see: http://groups.yahoo.com/neo/groups/dopplergram/info for MM-SSTV see: http://groups.yahoo.com/neo/groups/MM-SSTV/info On Tue, 2014-04-29 at 09:31 -0400, Slava Baytalskiy wrote: > Hello everybody! > Ever since i got my new P3 - i've been looking at people's signals > (naturally). > And i've noticed the following: > When using USB on 10 meters, talking locally, there are a couple of folks > that use ICOM radios and i can see these spikes on the left of the carrier. > Normally, in USB, all the signal shows up on the right, correct? > But with these guys there's a lot of signal on the left as well. > And they sound a bit robotic, as if they were off frequency a bit.
