"My equipment has optimum filtering when operating in SSB digital modes only when I center the frequency at 1500 Hz. Therefore, I move my VFO appropriately if I hear something that I want to decode. I only move around the waterfall for casual checking of signals or if they are very strong and I am betting that I won't need any filtering in place. I admit that there have been a number of times that I was in QSO with someone away from the optimum 1500 Hz point and some QRM appeared that I could not filter out."
I appologize, since I didn't realise that it is equipment defficiencies which do not allow you to change from the 1500hz center point. It must be an Icom thing, since the Kenwood equipment I am using permits centering on 1000,1500, or 2210 hz. I think that you should take up your cause with all the many digital, RTTY and SSB nets around the world who only specify a VFO frequency as opposed to the exact frequency of the offset or sideband in use. It certainly is a "slap in the face" to good operating practices and should not be condoned by experienced operators anywhere. Some remedial math might also be in order since 14109.5 + 1500hz is 14111.0 ( not that this supports my argument or anything) "Nuf said, will continue to bumble along with VFO frequencies, trusting that others can deal with the vagarities of their equipment, and hope that we can co-exist for the common good. somewhat tongue-in-cheek, John VE5MU ------------------------------------------------------------------------------ No virus found in this incoming message.
