Hello up in WNY! Unfortunately, there's really nothing private in using CTCSS, just to the ops using it. Everyone else tuning can hear everything that's going on, and maybe that very low BRRRRRRRRRRRRRRRRRRRR sound in your audio that the CTCSS tone puts there. (Which is not as sub-audible as people are lead to believe.) Anyway, all that CTCSS toned squelch does is keep squelched all the other traffic and noise that comes on to your transceiver. When a signal is RX'ed with that CTCSS tone that matches what your radio is set to, the squelch opens. Since 11M operations in this country don't use CTCSS tones, pretty much every 11M receiver and transceiver are wide open to listen to your COMM's. (a.k.a., they are carrier operated squelch, meaning any signal that goes up to a listener's squelch threshold level will just hear what's there.) Yep, CTCSS makes it so you don't hear everything that's on your FREQ, but anyone on your FREQ will still hear everything you TX, whether you are toned, or not. So, what's another option? There's voice scrambling out there, where a listener will hear what sounds like chickens in a feeding frenzy to others tuning in. That's employed commercially on the VHF / UHF bands, but I've yet to hear it on HF. But, I don't see why that wouldn't work. You could do DV (Digital Voice), modes like Icom's D-STAR, or Yaesu's C4FM FUSION. The Icom IC-7100 I believe can do D-STAR HF, and the Yaesu FT-991A can do C4FM FUSION there. Most CB'er will not have the ability to de'MOD DV, so that could be private for you, for a little while. However, you won't be private to some tuning HAM's, or fed monitoring stations. Oh... To answer your question on when Cycle 25 revs up? DX F2 propagated stations could indeed block your traffic, and make it so the traffic that you want on CTCSS toned is blocked out at times. Why did I go through this long winded? I wasn't too sure if you knew really how CTCSS tech worked, and my apologies, if you do. Anyway, good luck.
