Hi Vic and all. I have kept my K2 (1188) up to date with all the A/B mods, however at times I see references such as the one below about T7 where a toroid may have been changed from the original windings to a revised spec. Are these documented anywhere, which toroids are now different and why? Thanks, 73, Deni F5VJC / GM3SKN K21188 ========================================================================= It looks fine, although I would move the two wider filters a bit to the right. There looks like about 6-8 db difference in attenuation between the widest and narrowest filters, which is probably on the high side of normal (although this tends to vary). I see about 4 db on mine, which is #709 but has had the crystals replaced and T7 rewound to current spec. I would be interested in knowing how much difference in attenuation others are seeing. I know that K1JD has an ANCIENT K2 (field test vintage) which has zero db difference! -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco
