Skip levels and local

[slowmover]

(Time limit grumble)

During Skip I have to back off RFG a fair amount, SQ not so much I also have to max RFP so that the usual poor radio rigs can hear me.

Without Skip we all have an easier time. My capture radius is improved for the odd angles when without, but it doesn’t terrifically affect my signal capture given better big truck rigs (export radios).

I have baseline settings for both periods. Took awhile to work out what was best as a starting point (max distance goal).

(NRC) AM/FM BILL 3

The President BILL III FCC CB Radio is Here!

The new Bill III FCC builds on the ultra-compact legacy of the earlier Bill and Bill II models and adds FM modulation with host of smart signal-processing tools into an ultra compact chassis that’s barely larger than a typical smart phone.

Yes! Ordered a Bill 3 yesterday. NRC put it over the top.

Looks like the Bill III could be the smallest mobile of all time. President should add SSB capability.

HARRISON is the SSB candidate (relative size).

The new AQUARIO 70 is tiny and with SSB ($399).

For short range the FM & P-channels make B3 ideal as trail & campground radio now that it has NRC.

Rock quarry excavator. Scale house. Gate guard.
There’s a long list of potential users.

— Used to be parked regularly a mile from a 24/7 beef plant. Constant chatter. Wouldn’t have been any requests to repeat. Trucker or Receiver.
Both had loud backgrounds.

If I keyed up I’d get bombed with, “What radio is that?” by the cattle haulers. They were making their way toward NRC STRYKER. Voice arising from a totally silenced background. Noise stripped from voice.

Clarity is King.

Yes, but the one from the industry magazine was about direct line of sight being impacted by heavy smoke.

Tropo is understandable. VHF direct line of sight getting impacted to the point of not being able to talk to a radio that they can "see" is another level.

I have measured the impact (of smoke) at microwave frequencies. And I can see it being a thing at UHF and VHF under certain very specific conditions of frequency, smoke density, and smoke source. But really, I would be surprised if it impacted HF at anything detectable in the field. Sure, there is probably some theoretical issue, or fractions of a DB in path loss that can be measured in the lab, but probably nothing that would be repeatable or reliably quantifiable in the open air.

I suspect that the makeup / source of the smoke would play a great deal also. Hydrocarbon based smoke? I bet that has more of an impact, and at lower frequencies (still don't think it would be much at HF though). But fine smoke and ash from undergrowth is probably a good bit less of an impact.

T!

I agree, I wish I could find the article. It was specifically about simplex VHF on wildland fires . It was noticed by end users, and took some careful testing to prove it.
