There is a DC spur at IF center though, so offset tuning should be used.              Wideband spur emissions are minimal, shouldn't interfere with anybody on HF.       Yet to get reception reports though, as now I have no license and no suitable       power PA.       --- SBBSecho 3.12-Linux        * Origin: War Ensemble - warensemble.com - Appleton, WI (1:154/30)       SEEN-BY: 1/123 19/10 90/1 105/81 120/340 457 123/10 131 129/305 154/0       SEEN-BY: 154/10 30 40 50 70 700 201/0 203/0 124 220/80 90 221/0 1       SEEN-BY: 221/6 360 226/30 227/114 229/101 200 424 426 616 664 1016       SEEN-BY: 229/1017 230/0 240/5832 249/206 317 400 280/5003 317/3 320/219       SEEN-BY: 322/757 342/200 423/81 460/58 633/0 267 280 281 384 410 412       SEEN-BY: 633/416 509 640/1138 1321 1384 712/848 770/1 3634/12       PATH: 154/30 10 203/0 221/1 640/1384 633/280 229/426           |
