Thanks for the capture Jay. The slant code was working fine when you
copied it, early on a very cold morning here. But as things warmed up
both dots and dashes exhibited unwanted startup offsets. Figure it's
because of the final single-supply op amp that is run off unregulated
battery voltage (the other op amps run off regulated 5 Vdc). May switch
to a modified version of DFCW until I can get to the beacon to install a
9 V regulator.
