G; I keep forgetting that you chaps use metric and guess it is kinda rude of us yanks always using Imperial? From: [email protected] To: [email protected] Date: Sat, 8 Mar 2014 18:04
Markus; But this 4' coil only takes me down from already resonant ant at 69 kHz. It is in series with those coils shown on shelf at operating position. At bottom of this 4' coil is a tap about 6 inch
Bob, I've got to admit I gave up trying to reverse-engineer the inductance of your loading coil, from the dimensions given in your other mail ;-) Markus From: [email protected] Bob Raide Sent: Satu

Dex, 2 Hz separation is ok, no problem there , it could be interaction with other 'dsp' based programmes, in the past it was found that Spec-Lab for some reason , possibly by sample rate , was intera

Hi Bob, noise was a bit better here than last night but not quite enough: around 5 UT, your modulated carrier produced ~ 10 dB SNR in 106 µHz, but still lacking maybe 5 dB to the opds threshold. Than
AC4IU is only 260 miles from my location. I see David shows no decodes of my signal until after I suspect Bob ceased his transmission. 2 Hz not enough frequency separation for optimum Opera reception

Hi Dex, 2 Hz is more than enough. Op-2H consists of dashes of approximately 33 and 66 second duration, so theoretically two signals could be placed as close as 0.03 Hz apart. Taking into acount a few
