After a recent update of O2 firmware to 2.044A, when I first turn the rig on its bandwidth (on LCW mode) is 1000 Hz. When I turn the rig off the bandwidth is usually 500 Hz and often less -- certainl
Thanks, Mark KA4ICK I'm just using the defaults, Mark: 100% and 5ms. (That's one of many things about the Orion I haven't yet experimented with.) From the manual's description the 3:1 dah:dit ratio
I picked this up on one of my other groups, where it was described with this quote: We've partnered with Google to offer our entire 137-year archive for free browsing. Each issue appears just as it d
Is a low-pass filter advisable or necessary with modern equipment (like my O2)? When I became active again in the mid-80s I automatically installed my old (1950s era) E. F. Johnson cylindrical LPF be
Trying to work the 10-meter contest that just ended from my high-noise QTH, I found a very narrow heterodyne on my Orion II, just one sideband from 28,027,618 to 28,027,627 Hz. (With my step set norm
Well, I guess what I'm asking is if this is internal to the Orion II; do other O2 owners find this narrow signal? (It's still here this snowy Maryland morning...) -- John, K3GHH
Still there, Fred; no change in strength. (I should have thought to do that myself...) John K3GHH wrote: Trying to work the 10-meter contest that just ended from my high-noise QTH, I found a very nar
