A lot of hams like CWL so that in order to make the note lower, they tune lower in frequency. Some prefer to know that a higher-pitched note is higher in frequency and they must tune up to center that station in the passband. (I like the latter myself.) In olden days we would turn the BFO knob to either the high side, so that tuning up caused the note to go up, or we would turn the BFO knob to the low side so that higher pitched notes were higher in frequency. Then we got these good crystal filters with crystal-controlled BFOs and lost the choice. (Well, I remember my Collins and Hammarlund receivers with product detectors still had adjustable BFOs.) Oh, I am feeling old right now. :-) -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 [email protected] +1.767.617.1365 (Dominica) +1.931.492.6776 (USA) (+1.931.4.WB6RQN) _______________________________________________ Flexedge mailing list [email protected] http://mail.flex-radio.biz/mailman/listinfo/flexedge_flex-radio.biz This is the FlexRadio Systems e-mail Reflector called FlexEdge.
