THANK YOU guys for your "Y" reports - I estimate the second harmonic of "Y" 8193.06 (or so) is about 15 dB below the fund, thus is about maybe 50 mW output! MarinDit is just a 2N2222 colpits osc. and 555 dit-timer IC to a too-short enamal-wire hidden in the parent's attic for the past 18-plus years...
.See if the THIRD harmonic of "Y" is audible. I once while on a trip to northern SASKATCHEWAN heard strongly the THIRD harmonics of all three 4096 desert beacons before we (the three guys involved) put output tuning on them to cut this syndrome! Those were when Hexie/Coxie/Kelsie were the dominant trio, now mostly gone save for the daytimer Coxie still honking away after 17 years...
BTW, if a weak CARRIER is hrd. on the "Y" fund freq. rather than the stronger CW-mode ident (about 4096.53) it might be AM-modulated to about 90% mod. level max. - with rock/exotic music I play when taking desert walks outta here...
I will start to give your bcn. reports when possible, but need a few days advance notice of special tests/freqs. other than regular 24/7 bcns, cuz I don't log onto here everyday... - 73 - MB
